System Marketplace online

(e - Commerce)

The development of the Internet led to the formation of a new world that is commonly known as cyberspace. In this virtual world every individual has the right and ability to interact with other individuals without any restriction that could prevent him. So globalization has actually perfect running in a virtual world that connects all the digital community.

From all aspects of human life affected by the presence of the Internet, the business sector is the sector most affected by the development of information technology and telecommunications as well as the fastest growing. Through e-commerce, for the first time all humans on earth have an opportunity and equal opportunity to compete and succeed in business in cyberspace.

Definition of E-Commerce
E-commerce is a type of mechanism in electronic business that focuses on individual-based business transactions using the Internet (technology-based digital network) as a medium of exchange of goods or services between two institutions (business to business) and direct consumers (Business to consumer), through time and space constraints which have been the things that are dominant. It can also mean a way of shopping or a trade online or direct selling that utilize Internet facilities where there are websites that can provide the service "get and deliver". Ecommerce will change all marketing activities and also at the same cut operational biaya2 to trading activities (trading)
During the fierce competition in the era of globalization, then the real competition lies in how a company can utilize e-commerce to improve the performance and existence in the core business.
With e-commerce application, should the relationship between the company and other external entities (suppliers, distributors, suppliers, consumers) can be done faster, more intensive, and cheaper than conventional application of management principles (door to door, one-to- one relationship). So e-commerce is not just a mechanism for selling goods or services through the medium of the Internet, but also against the occurrence of a business transformation that changed the way companies conduct their business activities. Develop and implement an e-commerce system
is not an instant process, but a transformation strategy and business system continues to grow in line with corporate developments and technology.

A.1 The process contained in the E-Commerce are as follows:

1. Presentation Electronis (Making Website) for products and services.

2. Direct booking and availability bill.

3. Ririskiky automated customer account can be safely (both account numbers and credit card numbers).

4. Payment is made directly (online) and transaction handling.

A.2 The benefits obtained by using the transaction through the E-Commerce for a company are as follows:

1. Increase revenue by using online channel they cost less.

2. Reduce costs associated with paper, such as letter postage, printing, reports, and so forth.

3. Reduce delays by using tansfer electronic / on-time payments and can be directly checked.

4. Speeding up service to customers, and more responsive service.

Examples of E-Commerce
A lot can be done through E-Commerce namely:
1. Purchase the book through online.
2. Electronic purchase via online.
3. Purchase of vehicles through online.
4. Purchase through an online clothing, etc.

Positive and Negative Impact of E-commerce

In the world of E-Commerce would have a positive impact and negative consequences.

Its positive impact, namely:

1. Revenue Stream (revenue stream) that may be new more promises that can not be met in a traditional transaction system.

2. Can increase market exposure (market share).

3. Lower operating costs (operating cost).
4. Widen the range of (global reach).

5. Increase customer loyality.

6. Improve supplier management.

7. Shorten production time.

8. Increasing the value chain (the chain of revenue).

Its negative impacts, namely:

1. Loss of financial terms is directly due to fraud. A fraudster transfer money from one account to another account or he has to replace all the existing financial data.
2. Theft of confidential information that is valuable. Disorders that arise may disclose all such confidential information to parties who are not eligible and can result in big losses for the victim.
3. Loss of business opportunities due to disruption of service. This error
is non-technical errors such as electricity suddenly goes out.
4. The use of access to resources by unauthorized parties. Suppose a hacker who managed to break into a banking system. After that he moved a number of someone else's account into his own account.
5. Loss of trust from consumers. This is due to various factors such as work done on purpose by others who try to slander the reputation of the company.
6. Unexpected losses. Disturbance caused by deliberate, dishonesty, improper business practices, human factor errors, human error or an error factor of the electronic system.

Most abuse comes from people in a dishonest course not from a sniffer on the loose on the Internet. The firewall itself is often used to enhance security, a firewall can be used as control of access to the system directly (firewall should digunakankan to control all access to the system, rather than simply to restrict access from outside into), another reason why a firewall is more difficult to access originating from outside than from within.

E-commerce is a process of supply,sale of of goods,ordering goods ,and purchase goods online. With the Internet, all can become more affordable and more practical. But in practice, there are concerns or risks that might occur, such as abuse of the trust account to saller buyer. Saller can use account no buyers for other things.

In addition, also at risk if it turns out Saller is only an empty site is not responsible, but this has got security handling of the LSS.

It should be noted also in Saller data security that can be uprooted by competitors or hackers to obtain sensitive data. It inibisadiantisispasidengan mounting internal and external firewalls.

The risk of using WIFI connection

The most effective method to prevent interception of data via Wi-Fi is to use a VPN. However, VPN is too complicated because at present there is no solution to the VPN plug-and-play. For modern society, technology, Wi-Fi (Wireless-Fidelity) is a part of everyday life. In the big cities in Indonesia, Wi-Fi not only penetrated the office. But also shopping centers, restaurants, coffee shops, hotels, campuses, and even housing-housing. The main function is Wi-Fi wireless internet access.

In public places, there is Wi-Fi that are served free of charge and some are paid. In public places also, for example in shopping centers, plenty of options usually available access point. Access points were visible when the notebook users have to select the SSID (Service Set Identifier), the alias name you want to use the wireless network. When a notebook is connected with a particular SSID, the notebook that was already entered into a Wi-Fi network.
Malware Analyst, Kaspersky Lab warns Christian Funk, notebook users should be vigilant when accessing Wi-Fi in public places. Because, Funk asserted, access the Internet through Wi-Fi network extremely vulnerable to attack in the form of data piracy. To trap the victim, criminals generally create a wireless access point (hotspot) for free or copy the login page of the Wi-Fi service provider trusted. Furthermore, criminals are just waiting for the victim lured into dangerous networks.
"To perform this attack, the perpetrator does not need to have technical knowledge of high-end computing. Actors only need to create a fake access point in order to trap the victim. Once the victim is trapped, then the players can tap into typed data that the victim in the web pages opened via Wi-Fi , "said Funk.
Funk explained that the main target of this attack is to steal credit card information on the victim when the victim make transactions online using the Wi-Fi. However, criminals also steal information such as e-mail accounts as well as their passwords, as well as the accounts used by victims to access Internet sites, such as social networking sites.
Funk warned, data theft has serious consequences. For example, if criminals could steal credit card information of victims, the criminals could take advantage of the victims credit card for shopping. Spending bill that also fell into the victim. Though the victim have never committed expenditure.
Another example, if criminals are able to steal account and password of your e-mail the victim, the criminals can take advantage of e-mails offering to spread spam (unsolicited e-mail address.) These crimes can be done if the criminals could steal another account, such as accounts of social networking sites.
Funk emphasized that the most effective method to prevent piracy of data via Wi-Fi network is to use a VPN (Virtual Private Network). With VPN, the data from the notebook users are sent to the server through a virtual tunnel, and vice versa. As a result, the data can not intercepted. However, Funk admits, VPN technology is too complicated for most notebook users.

"Encryption of wireless data traffic is too complicated for users. At this time there has been no VPN solution that is plug-and-play (can be used without the need setting)," said Funk.

Without VPN, Wi-Fi users should not conduct financial transactions or access the internet banking. Also, users should be diligent, industrious change the password of the accounts owned. If you must conduct internet banking transactions in a mobile, Funk suggested, notebook users should use the 3G internet network.

"3G Internet becomes an attractive alternative because of the Wi-Fi and 3G data traffic is more difficult to plow. Also, 3G Internet network has wider coverage than Wi-Fi. speed 3G internet is also more than enough for most purposes mobile computing," said Funk .

Encryption for Data Security in Networks

One of the things that are important in communication using a computer to ensure the confidentiality of the data is encrypted. Encryption dalah a process to change a code of which can be understood to be a code that can not be understood (not legible). Encryption can be interpreted as a code or cipher. A coding system using a table or a dictionary that has been defined to replace the words of the information or that are part of the information sent. A cipher uses an algorithm that can encode all data streams (stream) bit of a message into an incomprehensible cryptogram (unitelligible). Because cipher technique is a system that has been prepared for the automation, then the technique used in computer and network security systems.In the next section we will discuss a variety of encryption techniques commonly used in security systems of computer systems and networks.

A. Conventional encryption.
This encryption process can be described as follows:

Plain text -> Encryption Algorithm -> Cipher text -> Algorithm Dekrispsi -> Plain text

User A | | User B

User B|---------------------- Lock (Key) --------------------|

Figure 1

Origin information that can be understood in symbolized by the Plain text, which then by the encryption algorithm translated into information that can not be to understand that symbolized the cipher text. The process of encryption consists of two algorithms and keys. Locks are usually a short string of bits that control the algorithm. Encryption algorithm will produce different results depending on which key is used. Changing the encryption key will change the output of encryption algorithms.Once the cipher text has been generated, then transmitted. In the next recipient of the cipher text received converted back to plain text and key algorithm and the same.Security of conventional encryption depends on several factors. First encryption algorithm must be sufficiently strong so that makes it very difficult to decrypt the cipher text with the basic cipher text. Furthermore the security of conventional encryption algorithms rely on the secrecy of the key is not the algorithm. That is assuming that it is very impractical to decrypt the cipher text based information and knowledge about the algorithm description / encryption. Or in other words, we do not need to maintain the secrecy of the algorithm, but enough with the secrecy of the key.

Benefits of a conventional encryption algorithm is the ease in use widely. With the fact that this algorithm does not need to be kept secret with the intent that the makers can and are able to make an implementation in the form of chips with low price. Chips can be widely available and provided also for several types of products. With the use of conventional encryption, security principle is to maintain the security of the key.

The model is widely used encryption is a model based on data encrytion standard (DES), taken by the Bureau of U.S. national standard in 1977. For the DES encryption of data on the 64 bit block using 56-bit key. By using this key, the 64 input data converted to a sequence of methods to 64-bit output. That the same process with the same key is used to change the encryption back.

B. Public-Key Encryption
One of the main difficulties of the conventional encryption is the need to distribute the keys used in a safe condition. An appropriate way has been found to overcome this weakness with a model of encryption that is surprisingly not require a key to be distributed. This method is known as public-key encryption and was first introduced in 1976.
Plain text -> Encryption Algorithm -> Cipher text -> Algorithm Dekrispsi -> Plain text User A | | User B

Private Key B----|

|---------------------- Lock (Key) --------------------|

Figure 2

The algorithm is as depicted in the image above. For conventional encryption, the key used in encryption and decryption cent is the same. But this is not actually the required conditions. But it is possible to construct an algorithm that uses one key for encryption and her partner, a different key, for decryption. Furthermore it is possible to create an algorithm in which knowledge of the encryption key encryption algorithm plus not enough to determine the key dekrispi. So the following technique will be done:1. Each - each of the systems in the network will create a pair of keys used for encryption and decryption of information received.2. Each - each of the system will publish the encryption key (public key) to install in public registers or files, while her partner still maintained as a private key (private key).3. If A wants mengisim message to B, then A will encrypt the message with the public key of B.4. When B receives a message from A then B will use the private key to describe the message from A.As we have seen, public-key distribution because it does not solve the problem needed a key to be distributed. All participants have access to a public key (public key) and private keys generated locally by each participant, so no need to be distributed. During each control system - each private key with both the communication becomes secure communications. Each partner's private key system to change the public key will replace the old public key. The weakness of public key encryption method is compared with conventional encryption methods encryption algorithm has a more complex algorithm. So for comparison of size and price of the hardware, the public key method will result in lower performance. The following table will show the various important aspects of the conventional encryption and public key.

Conventional Encryption
Required to work:
1. The same algorithm with the same key can be used for the decryption process - the encryption.
2. The sender and receiver must share the same algorithm and key.
What is needed for security:
1. Keys must be kept secret.
2. It is impossible or highly impractical to translate that information is encrypted.
3.Knowledge of algorithms and sample of an encrypted word is not sufficient to determient the key

Public Key Encryption
Required to work:
1. The algorithm used for encryption and decryption with a pair of keys, one for encryption one for decryption.
2. The sender and receiver must have a suitable key pair.
What is needed for security:
1. One of the key must be kept secret.
2. It is impossible or highly impractical to translate that information is encrypted.
3. Knowledge of algorithms and sample of an encrypted word untu insufficient to determine the key.

NETWORK SECURITY

1. What is Network Security

One thing to keep in mind that there is no network of anti tapping or no computer network is completely secure. The nature of the network is to perform communication. Any communication to fall into the hands of others and abused. Security systems help secure the network without blocking its use and place of anticipation when the network is successfully penetrated. Also, make sure that the user in the network have enough knowledge about security and make sure that they accept and understand the security plan that you created. If they do not understand this, then they will create a hole (hole) security on your network.

There are two main elements forming the network security:

• Wall of security, both physical and virtual, which is placed between the devices and network services used and the people who would do evil.
• Security Plan, which will be implemented together with other users, to keep the system can not be penetrated from outside.
Defined security aspects of these five points.

a. Confidentiality Require that information (data) can only be accessed by parties who have authority.

b. Integrity Requires that information can only be modified by parties who have

authority.

c. Availability Requires that information available to parties who have authority when needed.

d. Require that a sender authentication information can be correctly identified and there is no guarantee that the false identity is not obtained.

e. Nonrepudiation Requiring that both the sender and receiver of information can not deny sending and receiving messages.

Attacks (interference) for security can be categorized into four main categories:

a. Interruption
An asset of a system being attacked so become unavailable or can not be used by the authorities. An example is the destruction / modification of hardware or network channels.

b. Interception
An unauthorized person gaining access to an asset. Parties in question can be a person, program, or other systems. An example is the interception of data in a network.

c. Modification
An unauthorized person can make changes to an asset. Examples are changes in the value of the data files, modify the program so that it runs with no proper, and the modification of message being transmitted in the network.

d. Fabrication
An unauthorized party inserts counterfeit objects into the system.
An example is sending false messages to others.

There are several principles that should be avoided in dealing with security issues:
Ÿ      silent and all will be fine
Ÿ      hide and they will not be able to find your
Ÿ      technology used complex / complicated, meaning safe

2. Concern Network Problems

Overview
Defining security (on a computer network) can be done by looking at the targets to be achieved through the concept of 'safe'. Here is a list of features
that can prevent / anticipate the attacks from outside parties or the party inside.

Security Policy
Before proceeding to the implementation of a more distant level should be determined first what was to be protected and protected from whom. Some of the following questions to help determine the security policies are taken.
1. What information is considered confidential or sensitive?
2. You protect your system from whom?
3. Do you need remote access?
4. Are passwords and encryption enough to protect?
5. Do you need Internet access?
6. What action do you do if you find that your system is compromised?
And many other questions depend on the form of organization you manage.
Security policy depends for what you believe other people, inside or outside your organization. Policy should be a balance between allowing the user to access the information needed while maintaining system security.

Physical Security
Physical in this section is defined as a situation where someone can get into the room server / network and can access these devices are illegal. Unauthorized persons could have been a guest, cleaning staff, delivery courier packages, and others who can get into the room and fiddling with existing devices. If someone has access to that room, that person can just install Trojan horse programs on the computer, booting from a floppy disk, or steal sensitive data (such as the password file) and unpack in a safer place.
To maintain security, put the server in a room that can be locked and make sure that the room was locked properly. To avoid surveillance, use a screen-saver that can dipassword. Set also all computers to perform the function of auto-logout after inactivity in a certain period.

BIOS Security

Actually, an admin is recommended to disable boot from floppy. Or it could be done by creating a password on the BIOS and set boot password.

Password Attack
Many people store important information on the computer and it is often a password that prevents    others   to   see it. To avoid attack user password then you should use a password that is pretty good. Hint password selection:
   • All passwords must consist of at least 7 characters.
   • Enter a combination of letters, numbers, and punctuation as much as possible with a record that still easy    to remember passwords. One way is to combine random words with punctuation or by combining the words with numbers. Examples: @ sweet melon flavor #, komputer0digital1, less 2001
• Use the first letter of a phrase that is memorable. Examples: parking is prohibited between the hours of 7 am and at 8 pm à dpap7php8s, no system is completely secure within the context of network à tasybbadkj
• Use a number or punctuation mark to replace the letters in the password. Example: success à k3b3rh45! L4n
• Change your passwords regularly

Malicious Code
Malicious code can be a virus, trojan or worm, usually in the form of code instructions that will burden the system so that system performance decreases. How to anticipate it could be seen at 6 the following example:
1. provide awareness to the user about the virus threat.
2. use a good anti-virus program on a workstation, server and internet gateway (if any).
3. teach and train users how to use anti-virus program
4. as admins should always update your anti-virus program and virus databases
5. Familiarize the user to NOT open the email attachment file or any file from a floppy before 110% sure or     not an attachment / file page "clean".
6. Make sure your security policy up to date.

Sniffer
Sniffer is a computer network communication interception devices utilizing premicious mode on ethernet. Because the computer communication network consisting of random binary data will typically have sniffer protocol analyzer so that a random binary data can be solved. Sniffer for the management functions can be used for network maintenance, to an outsider can to break down the system.
The easiest way to anticipate the sniffer is using a secure application, for example: ssh, ssl, secureftp etc.

Scanners
Network services (network service) of different runs on different ports as well. Each network service running on a particular network address (eg 167.205.48.130) and listening (listening) in one or more ports (between 0 to 65 535). Both make up what is called a socket address that uniquely identifies a service within the network. Ports 0 to 1023 the most commonly used is defined as a well-known number in the UNIX convention and described in RFC 1700.
Port Scanner is a program designed to find the service (service) what is running on the host network. To gain access to the host, the cracker must know the points of weakness that exist. For example, if a cracker has to know that the host is running the ftp server, he can use the weaknesses that exist on the ftp server to gain access. From this passage we can conclude that the service is not absolutely necessary should be removed to minimize the security risks that might occur.
Similar to a port scanner in the previous section, network scanner provides information on the intended target, such as the operating system used, an active network service, type of machine that is connected to the network, and network configuration. Sometimes, network scanner also integrates port scanners in their applications. This tool is useful for finding information about the target as much as possible before doing the actual attack. By knowing the conditions and network configurations, one would more easily enter and damage the system.
Example scanners: nmap, netcat, NetScan Tools Pro 2000, SuperScan

Spoofing
Spoofing (impersonation), usually done by irresponsible parties to use the facilities and resources of the system. Spoofing is a technique that is detected as an undercover identity that is not true, eg: posing as a specific IP, computer name and even a certain e-mail address. The anticipation can be done by using a firewall application.

Denial of Service
Denial of Service (DoS) attack in which a party is to exploit aspects of the Internet Protocol suite to block access to those who are entitled to information or systems under attack. Hole that allows denial is in category C, which is in a low priority. These attacks are usually based on the operating system that is used. That is, this hole is in the network part of the operating system itself. When this kind of hole appears, this hole must be repaired by the owner of the software or patched by the vendor that issued the operating system. Examples of this are TCP SYN attack where a network connection request is sent to the server in a very large number. As a result, the server was flooded with requests and the connection becomes slow or even not be achieved at all. These holes are almost in all operating systems running TCP / IP to communicate on the Internet. This seems to be an issue contained in the design suite TCP / IP, and is something that is not easily solved.
In a DoS attack, someone can do something which interfere with the performance and operation of the network or server. As a result of this attack is slow in responding servers or networks, or can even cause crashes. DoS attacks interfere with the legitimate user to obtain a legitimate service, but does not allow a cracker to get into the existing network system. However, this kind of attack against a server that handles e-commerce activities can result in financial losses.

Dangers of Cigarette Smoke Effects Human Body For Health

Cigarettes are toxic things that give effect to relax and feel more manly suggestion. Behind the usefulness or benefits of cigarettes that contained a piece of a very big danger for people who smoke and those around smokers who never smoked.

1. Cigarette smoke contains more than 4000 chemicals of which 200 of them poisonous and 43 other types can cause cancer in the body. Some substances that are dangerous are tar, nicotine, carbon monoxide, etc..

2. Cigarette smoke is just dead on an ashtray containing three times the cancer-triggering substances in the air and 50 times contain pengeiritasi eyes and breathing. The shorter the higher levels of cigarette toxins that are ready to float into the air. A place filled with cigarette smoke pollution is a more dangerous place than pollution on the streets are jammed highway.

3. Someone who tried smoking usually be addictive because cigarettes are addictive is difficult released under any circumstances. A heavy smoker will choose to smoke than eat if their money is limited.

4. Expensive price of cigarettes would be very burdensome people who are poor, so that his family health and welfare funds are often diverted to buy cigarettes. Rooms with famous brands are usually owned by foreign tobacco companies coming from abroad, so the money spent on smokers will flee to foreign countries that reduce national income. Cigarette factory that employs many workers will not be able to improve living standards for employees, so if the cigarette factory closed down workers can be employed in other establishments that are more creative and bring in foreign exchange.

5. Most smokers will usually invite other people who do not smoke to smoke to feel the same suffering with it, that is trapped in an evil addiction cigarette smoke. Most smokers are in a more deliberately smoking in public places for the exhaled cigarette smoke can be inhaled to others, so that others will get cancer.

6. Activities that damage the body is a sin, so that cigarettes can be categorized as an unlawful object or item that must be avoided and shunned as far as possible. Ulema or religious scholars who smoke may have different perceptions in this regard.

Conclusion:

So it can be concluded that smoking is an activity undertaken stupid humans who sacrifice money, health, social life, reward, positive perceptions, and so forth. So be grateful if you do not smoke, because you are a smart / clever.

When someone offers a cigarette then starting with the good. Feeling kasihanlah in those who smoke. Do not listen to those who think you are lower than they otherwise follow-up smoking. because in the hearts and minds of those who are sane they want to quit smoking.

Development of Information Technology II

Finally, I can finish this article, after all this time I tried to write, write, and write a decent article in the post. Okay, enough of this story is not important, let's start it.

In the Government Sector (e-government).

E-government refers to the use of information technology by government, such as using the intranet and the Internet, which has the ability to connect the purposes of residents, businesses, and other activities. Can be a business transaction process between the public and government through automation and networking systems, more commonly known as the world wide web. At its core e-government is the use of information technology to improve relations between the government and other parties. the use of information technology is then produced new forms of relationships such as: G2C (Governmet to Citizen), G2B (Government to Business) and G2G (Government to Government).

Benefits of e-government can be perceived among others: (1) service better service to the community. Information can be provided 24 hours a day, 7 days a week, without waiting for the opening of the office. Information can be sought from the office, home, without having to physically come to the office of government. (2) Improving the relationship between government, business, and the general public. The openness (transparency), the expected relationship between the various parties would be better. This openness eliminates mutual suspicion and resentment from all sides. (3) community empowerment through information that is easy to obtain. Given sufficient information, the public will learn to be able to determine his choice. For example, data about the school: the number of classes, student capacity, passing grade, and so forth, can be displayed online and used by parents to choose the right school for their children. (4) Implementation of a more efficient government.

Finance and Banking

When this has been a lot of economic actors, especially in big cities that no longer use cash in payment transactions, but has used modern banking services.
Modern banking services that exist only in big cities is understandable because the current economic growth is still concentrated in large cities only, which causes the velocity of money is also concentrated in big cities. So the banking sector was rather slow in its expansion into the regions. This is somewhat due to the current condition of infrastructure in addition to geographical aspects of Indonesia's unique and spacious.
To support the successful operation of a financial institution / banking like a bank, it is definitely needed a reliable information system that can be easily accessed by customers, which in turn will depend on information technology online, for example, a customer can withdraw money wherever he is as long as There is no service from the bank ATM, or a customer can check balances and transfer money to another account in a matter of minutes, all transactions can be done.

The development of telematics technology and infrastructure in Indonesia will greatly assist industry development in the financial sector, such as expanding the scope of business by opening branches in the region, as well as information exchange among insurance companies, brokers, the banking industry, as well as other financing institutions.

Banking and financial institutions have been influenced strongly by the development of products in information technology, even they can not operate again without information technology. This sector requires the development of products in information technology to provide their services to their customers.

The development of information technology is strongly influenced by human resource capacity in understanding the information technology components, such as hardware and computer software; network system either LAN or WAN and telecommunication systems that will be used to transfer data. The need for information technology-based energy continues to rise.

Development of Information Technology

2008-09-10T23:29:00.000+07:00

The development of information technology to improve performance and enable a variety of activities can be performed quickly, precisely and accurately, so that ultimately will improve productivity. Development of information technology show emergence of various types of activities based on this technology, such as e-government, e-commerce, e-education, e-medicine, e-laboratory, and others, all of which were based electronics.

Preliminary

Information Technology is a technology used to process the data, including the process, obtain, compile, store, manipulate data in various ways to produce high quality information, information that is relevant, accurate and timely, which is used for personal, business and government and is a strategic information for decision making. This technology uses a computer to process the data, the network system to connect one computer to another computer as needed, and telecommunications technology used for data and is accessible globally.

The role that can be given by the application of information technology is getting information to personal life such as information about health, hobbies, recreation, and spiritual. Then for professions such as science, technology, trade, business news, and professional associations. Means of cooperation between individuals or groups that one with another person or group without knowing the limits of distance and time, country, race, economic class, ideology or other factors that may inhibit exchange ideas.

Development of Information Technology spur a new way of life, from beginning to end of life, life is known as e-life, meaning life has been influenced by a variety of needs electronically. And now it is overflowing with a variety of letters that begin with the prefix e such as e-commerce, e-government, e-education, e-libraries, e-journal, e-medicine, e-laboratory, e-biodiversitiy, and still others are based electronics.

Evolution of the Global Economy

Until two hundred years ago the world economy is agrarian in which one of its main characteristics is the land is the most dominant factor of production. After the industrial revolution, with the invention of the steam engine, the global economy evolves toward industrial economy with its main characteristic is the capital as the most important factor of production. By the turn of the century now INL, humans tend to occupy a central place in the production process, because of the economic phase we are entering is based on knowledge (knowledge based) and focuses on information (information focused). In this case the role of telecommunications and informatics as a key technology (technology enabler.)

The progress of information technology and telecommunications so rapidly, allowing the implementation of new ways for more efficient production, distribution and consumption of goods and services. It is this process that brings people into the Society or Information Economy. This new society is also often referred to as post-industrial society.
Whatever its name, in the information age, physical distance or geographical distance is no longer a factor in human relations or inter-agency effort, so that the universe into a hamlet of the universe or the "Global village ‿. So often we hear the term "distance is dead" or "distance is dead" increasingly evident truth.

Role of Information Technology

In our lives in the future, information technology and telecommunications sector is the most dominant sector. Anyone who mastered this technology, then he will become a leader in the world. Information technology plays a role in many fields, among others:

1. Education (e-education).

Globalization has sparked a trend shift in education from the conventional face to face education toward a more open education (Mukhopadhyay M., 1995). As an example we saw in the French project "Flexible Learning ‿. This is reminiscent of Ivan Illich forecast early 70s about the "Education without schools (Deschooling Socieiy)" which in extreme teacher is no longer needed.
Bishop G. (1989) predicted that the future of education will be flexible (flexible), open, and can be accessed by anyone who needs without the view factor type, age, or previous educational experience.
R. Mason (1994) argues that the future of education will be determined by the network information that enables interaction and collaboration, rather than building schools. However, technology will continue to widen the gap between the rich and the poor.
Tony Bates (1995) states that technology can improve the quality and coverage when used wisely for the education and training, and has a meaning that is essential for economic prosperity.
Alisjahbana I. (1966) suggested that the approach to education and training will be "At that moment (Just on Time) ‿. New teaching techniques will be two way, collaborative, and inter-disciplinary.
Romiszowski & Mason (1996) predicts the use of "Computer-based Multimedia Communication (CMC) ‿ that are synchronous and asynchronous.
From the forecasts and views of scholars can be concluded that with the influence of globalization, the future of education will be more open and two-way, diverse, multidisciplinary, and related to the productivity of work "on the spot ‿ and competitive.With the development of information technology in education, so when it is already possible to place a distance learning using the internet to link between students and professor, saw the value of an online student, financial checks, view class schedules, send the tasks assigned faculty and so on, all it has to be done.

A major factor in distance learning that have been considered a problem is the lack of interaction between lecturers and students. However, with the internet media is very possible to make interaction between faculty and students both in the form of real time (real time) or not. In the form of real time can be done for example in a chatroom, a direct interaction with real audio or real video, and online meetings. That is not real time can be done with mailing lists, discussion groups, newsgroups, and bulletin board. With the above interaction of faculty and students in the class may be replaced even if not 100%. The forms of material, exams, quizzes and other educational ways can also be implemented into the web, such as teacher materials made in the form of presentations on the web and can be downloaded by students. Similarly, with exams and quizzes are created by faculty can also be done in the same way. Settlement administration can also be solved directly in a single registration process, more so in support with the online payment method.

A web-based distance education, among others, should have the following elements: (1) Center for student activities; as a web-based distance learning community must be able to make this facility as a place of student activity, where students can add the ability, reading course material, find information and so forth. (2) Interaction within the group; The students can interact with one another to discuss the materials provided by lecturers. Lecturers may be present in this group to give a little review of the material that gives. (3) student administration system, where the students can see information about student status, student achievement and so forth. (4) Deepening materials and examinations; Usually quis faculty often conduct brief and tasks aimed at deepening of what has been taught and do a test at the end of the study. It also can be anticipated by the web-based distance learning (5) digital library; In this section, there are a variety of information literature, not limited to books but also on digital libraries such as sound, images and so forth. This section is for support and shape of the database. (6) online material outside the course material; To support the lectures, required reading material also from other web. Hence in this section, lecturers and students to directly engage to provide other materials for publicizing to other students via the web.
To realize the above ideas and desires in a form of reality is not an easy job but if we look to other countries which have long developed a web-based distance learning, have a lot of institutions or agencies that use this method. Not only the skills possessed by the engineer who needed but also the various policies in education influenced its development. When viewed from the readiness of supporting facilities such as hardware, I suppose that this is no doubt. Only one who has always been a major concern of Internet users in Indonesia is the bandwidth problem, of course with limited bandwidth this is the comfort, especially on non-text based material.

In the global era, offering scholarships appeared on the internet. For most students in the world, the tuition fee to obtain the best education is generally still considered expensive. Very unfortunate if there is a clever student in his class can not continue school because not afford the tuition. Scholarship information is the key to success can no long these potential students.

Until this article first, maybe next week we'll dial again. If you want to continue reading this article still continues to follow developments in bremavillages.blogspot.com ... okay ^ _ ^

The Development of Windows and Microsoft

2008-07-03T06:07:00.000+07:00

For those of you who are currently reading this paper would be familiar with the name Windows. Yes, windows is the operating system made by Microsoft that was founded by Bill Gates.

Like the saying goes not know it was love, so it's good to know colleagues trace the history and development of the operating system of bill gates homemade om this.
Windows 1.0
The first version of Microsoft Windows, called Windows 1.0, released on November 20, 1985. This version has many shortcomings in some of the functionality, making it less popular in the market.

Windows 2.x
Windows version 2 came out on December 9, 1987, and became slightly more popular than its predecessor. Most gained popularity because of its proximity to graphical applications made by Microsoft, Microsoft Excel for Windows and Microsoft Word for Windows. Microsoft Windows eventually obtained a significant improvement when Aldus PageMaker appeared in versions for Windows, which previously could only walk on the Macintosh. Some experts noted this computer historians as the emergence of an application that behavior is significantly other than Microsoft's initial success as Microsoft Windows.
Windows version 2.0x using real-mode memory model, which is only able to access up to 1 megabyte of memory. In such configurations, Windows can run any other multitasking application, such DESQview, which runs in protected mode offered by the Intel 80286.

Windows 3.0
Microsoft Windows eventually achieve significant success when stepping on version 3.0, released in 1990. In addition to offering increased capabilities to Windows applications, Windows 3.0 is also able to allow users to run several MS-DOS applications simultaneously (multitasking), because this version has been introduced virtual memory.
This version is precisely what makes the IBM PC and kompatibelnya serious challenger to the Apple Macintosh. This is due to the increased graphics processing performance at that time (with the graphics card Video Graphics Array (VGA)), and also protected mode / 386 Enhanced mode that allows Windows applications to use more memory with an easier way than what offered by MS-DOS.
Windows 3.0 can run in three modes, namely the real-mode, standard mode, and 386 Enhanced mode, and is compatible with the Intel family of processors from Intel 8086/8088, 80286, up to 80 386. Windows 3.0 will try to detect which mode to use, although users can force Windows to work in a particular mode only by using certain switches when running it
• win / r: force Windows to run in real mode
• win / s: forcing Windows to run in standard mode
• win / 3: The force Windows to run in 386 Enhanced mode.
Version 3.0 is also the first version of Windows that runs in protected mode, although the 386 enhanced mode kernel was an enhanced version of the kernel from the kernel in protected mode Windows/386.
Because of the backwards compatibility feature, Windows 3.0 applications must be compiled using 16-bit environment, so that did not use the Intel 80386 microprocessor capability, which is actually a 32-bit processors.
Windows 3.0 is also present in the version of "multimedia", referred to as Windows 3.0 with Multimedia Extensions 1.0, which was released several months later. This version is bundled with the existence of "multimedia upgrade kits," which consists of a CD-ROM drive and a sound card, like Creative Labs Sound Blaster Pro. This version is the pioneer of all the multimedia features included in later versions of Windows, like Windows 3.1 and Windows for Workgroups, and become part of the Microsoft Multimedia PC specification.
The features mentioned above and support the application software market growing 3.0 makes Windows extremely successful in the market. Noted, within two years prior to the release version of Windows 3.1, Windows 3.0 sold 10 million copies. Finally, Windows 3.0 was a major source of revenue to Microsoft, and Microsoft did make some revisions to the original plan.

stem), and in theory prevents the application to the memory space owned by other Win32 applications with

Windows 95

Windows is superior in user interface and multitasking. Windows 95 is the windows that are considered revolutionary and bring a new era of computing. Released August 24, 1995.

Microsoft has two advantages of this release: 1) it is impossible for consumers to run Windows 95 on a DOS operating system not made by Microsoft which is much cheaper, 2) although traces of DOS were never completely removed from the system, even versions of the plug a version of DOS to be loaded as part of the boot process, Windows 95 runs on its own in the 386 Enhanced mode, using virtual memory and memory addressing model flat 32-bit. Features that make Win32 applications for maximum virtual RAM as much as 2 gigabytes (with 2 gigabytes of the rest are reserved for the operating sy

out the approval of the operating system. In this case, the functionality of Windows 95 approaching what is owned by Windows NT, although Windows 95/98/Me do not support more than 512 megabytes without editing the system configuration hassle.

Before you replace it with a new Windows version, Microsoft released Windows 95 in five different versions, namely as follows:
• Windows 95 - the actual release of Windows 95
• Windows 95 A - includes an update of Windows 95 Original Service Release 1 (OSR1) are inserted directly on the installation.
• Windows 95 B - includes several other major updates, like the FAT32 file system, and Internet Explorer 3.0. This version also known as Windows 95 OSR2, or many people in Indonesia call it Windows 97.
• Windows 95 B USB - Windows 95 or Windows 95 OSR2.1 is the version that offers support for bus-based hardware Universal Serial Bus / USB.
• Windows 95 C - or Windows 95 OSR2.5 includes all the features above, plus Internet Explorer 4.0. This version is the most recently released version of Windows 95 series.
Windows 95 OSR2, OSR2.1 and OSR2.5 not released to the public, but only to OEMs who want to use the operating system into the computer makes. Some companies even

sell OEM new hard disk with operating system Windows 95 OSR2 on it. Besides the features contained in Windows 95, Microsoft also introduced Microsoft Plus! for Windows 95 that includes several additional features that are not owned by Windows 95.

Windows 98

Released on June 25, 1998, the first Windows 98 was a very bad windows. Slow, frequent crashes and other problems. Changes in the kernel and overall system overhaul to make its sales increased due to fast, and no longer crashes (even the most stable windows ever) with his release of Windows 98 in 1999
Windows ME
Filling the gap between the release of Windows 98 and XP, in lahirkanlah windows ME. The concept of a new concept introduced with Windows ME. 1 in the then popular concept in one day there was a "plug and play". Unfortunately the GUI is bad and too geeky to make him unpopular.
Windows Me is the last operating system based on monolithic kernel of Windows 9x and MS-DOS. This version became the final version of the Windows operating system that does not have a Windows Product Activation (WPA).

Windows 2000
Microsoft released Windows 2000 on February 17, 2000, an earlier version known as Windows NT 5.0 or NT 5.0. " Version of Windows 2000 is aimed at two market share, the market share of workstation and server market share as well.
Among the features of the most significant Windows 2000 is Active Directory, an alternate network model domain NT network model, which uses technology that is the industry standard, such as Domain Name System (DNS), Lightweight Directory Access Protocol (LDAP) and Kerberos to link between a machine to another. Windows Terminal Services as well, which in Windows NT 4.0 is only contained in one product, the Windows 2000 contained in all versions of the server. New features are adopted from the Windows 98 also instilled in them, such as an improved Device Manager (using the Microsoft Management Console), Windows Media Player, and DirectX 6.1 (which allows the kernel-based operating system Windows NT to run the game). Windows 2000 also is a version of Windows NT-based kernel is the last that does not require users to do the activation to it.
Although Windows 2000 can update the previous computer running Windows 98, Windows 2000 is not considered as products suitable for home users. The reason many, among them the lack of device drivers for many devices such as scanner users (scanner) and also the printer (printer), at the time of release. The situation was finally turned on when Windows XP was released by Microsoft.

Windows 2000 is available in six editions, namely:
• Windows 2000 Professional
• Windows 2000 Server
• Windows 2000 Advanced Server
• Windows 2000 Datacenter Server
• Windows 2000 Advanced Server Limited Edition
• Windows 2000 Datacenter Server Limited Edition

Windows XP
October 2001, Microsoft released Windows XP, Windows version most widely in use around the world until now, a lot of praise throughout the news. Review A good score makes Windows XP dominate the PC market today. Windows XP was first to break the sale of windows into Home and Professional. Only distinguish a few features that may not be used by home users rather than professional users.
Windows XP is a version of the Windows operating system the longest (at least until recently), because it ranges from 2001 to 2007, when Windows Vista was released to consumers. Ranks of the Windows XP operating system finally passed by Windows Vista on January 30, 2007.
Windows XP is available in several versions:
• Windows XP Home Edition, intended for home desktop and laptop market.
• Windows XP Home Edition N, the same as a regular Home Edition, but do not have Windows Media Player, because the rules did not allow the European Union.
• Windows XP Professional, which is aimed at power users and businesspeople.
• Windows XP Professional N, the same as the Professional Edition, but do not have Windows Media Player, because the EU regulations do not allow it.
• Windows XP Media Center Edition (MCE), released in November 2002, Windows XP Home Edition is aimed at desktop and laptop computers with an emphasis on home entertainment.
o Windows XP Media Center Edition 2003
o Windows XP Media Center Edition 2004
o Windows XP Media Center Edition 2005, which was released on October 12, 2004.
• Windows XP Tablet PC Edition, which is aimed at Tablet PCs (PCs with touch screen)
o Windows XP Tablet PC Edition 2005
• Windows XP Embedded, which is intended for embedded systems (embedded systems)
• Windows XP Starter Edition, aimed at computer users in developing countries.
• Windows XP Professional x64 Edition, released on 25 April 2005 for home-based systems and workstations that use 64-bit processor-based x86-64 instruction set (AMD64 or Intel EM64T).
• Windows XP 64-bit Edition, is a version of Windows XP are intended for Intel's Itanium line of processors, which maintain compatibility with 32-bit applications using the emulator software. This version is the same as Windows XP Professional, in terms of its features. This product was discontinued in September 2005 when the last vendor Itanium processor-based workstation to stop its products as "workstations", because they tend to focus on Itanium as a computer database server.
o Windows XP 64-bit Edition, 2003, was based on the code base of Windows NT 5.2 (same as Windows Server 2003).

Windows Vista
Vista brought a big change in the kernel, GUI and set of additional features that promise. Unfortunately despite already having the addition of features and user interface, Vista is not successful in the market because it has some flaw that is very disturbing, especially for critics. Vista too slow and not much better than Windows XP in use daily.
Windows Vista Aero graphical interface displays her alluring, the Welcome screen and Start menu.
Windows Vista uses the version number 6.0, so that there was indeed a significant difference when compared to the version with Windows XP that use version 5.1 or Windows Server 2003 (5.2). Because, it's Windows Vista has many fundamental differences, particularly at the basic architecture of the operating system.
Windows Vista sold in several editions:
• Windows Vista Starter
• Windows Vista Home Basic
• Windows Vista Home Premium
• Windows Vista Business
• Windows Vista Enterprise
• Windows Vista Ultimate

Windows 7
The next release after Windows Vista was known as Windows 7, formerly known as Blackcomb and Vienna. It has a kennel Windows NT version 6.2 SP2 of Windows Server 2008. Windows 7 has a security and new features. Windows 7 is the type of Windows Server 2008 SP2. Windows was released on October 22, 2009. Existing features in Windows 7 60% the same with Windows Vista. Some of its features are: Jump Lists, Taskbar is open the program with a small display, Windows Media Player 12, Internet Explorer 8, and others. Several unique features is the Sidebar which changed its name into the free Gadget Gadget and put it everywhere (not like the Sidebar which can only be placed in certain places). That feature makes Windows 7 to be attractive. Spektifikasi Windows 7 is lighter than on Windows Vista. The price is also cheaper than in Windows Vista.

Information Technology is a technology used to process the data, including the process, obtain, compile, store, manipulate data in various ways to produce high quality information, information that is relevant, accurate and timely, which is used for personal, business and government and is a strategic information for decision making. This technology uses a computer to process the data, the network system to connect one computer to another computer as needed, and telecommunications technology used for data and is accessible globally.

One special feature of the field of Information Technology is the focus of attention is the field of science that are more applicable. More information technology disciplines lead to the data and information management in an enterprise (company or other employee organizations), with the use of computer technology and data communications and more emphasis on the utilization of technical tools available to improve productivity. In its development in line with the new economic paradigm, the information technology becomes a powerful weapon in improving communication and interaction with stake holdernya enterprise.

In the history of the development of education, information technology is part of the medium used to convey the message of science on the crowds, ranging from printing technology a few centuries ago, such as a printed book, through media such as telecommunications, sound recorded on tapes, video, television, and CD. Current developments in information technology, Internet, direct the history of educational technology on a new path. Online services in both degree and non education degree is basically to provide educational services to users (students) by using the Internet as a medium. This online service can consist of various stages of the process of educational programs such as: registration, test entry, payment, lectures, case assignments, case discussions, exams, assessments, discussions, announcements, etc.. Distance education can take advantage of Internet technologies to the maximum, can provide the effectiveness in terms of time, place and even improve the quality of education.

From the definition above, it appears that information technology is not limited to computer technology, but also including telecommunications technology. In other words that information technology is the result of convergence between computer technology and computer telekomunikasi.Teknologi technology is the technology associated with computer devices such as printers, fingerprint reader, CD-ROM, processor, disk, and others. Computer is a versatile machine that can be used for processing any data into useful information. This is possible because

Computers can be controlled by a program consisting of a series of instructions. The computer will act on instructions received from the program. In other words the computer will act as you wish the program makers.
Communication or telecommunication technology is long-distance communication technology. Including telecommunications technology that we use everyday is the telephone, television, radio, handy-talkies, mobile phones. It said earlier that information technology is the convergence between computer technology and telecommunication technology, the current telecommunications technology mentioned above has to be used to connect several computers. So that multiple computers can communicate with each other easily. This is the meaning of the word "convergence" over the then commonly known as Information Technology.

Information technology up to now developing very rapidly along with the discovery and development of science in the field of information and communication. It is able to create tools that support the development of information technology, ranging from communication systems to direct communication tools as well as two-way (interactive).

Basically, information technology equipment includes 3 main tools:
a) Computer Systems.
b) Network Communications System
c) Net Tools.

a. Computer Systems
Computer is an electronic device that is capable of receiving, processing, and storing data, and produce output in the form of text, images, symbols, numbers and sounds. In operation, forms, systems and functions, the computer consists of 2 (two) parts, namely hardware and software.

b. Hardware (Hardware)
To meet the need for trending information, humans continue to develop hardware to support it. To accommodate this, humans create a variety of equipment that support that desire. Computer hardware devices can be grouped into an input device (didntaranya: Keyboard, Scanner), the process (among them: CPU), output and storage devices (such as: Monitor, and Printer), and a data storage device (such as: CD-ROM, Compact Disk, Floppy Disks, Hard disk).

Computer Network Components

2008-05-08T21:14:00.000+07:00

Computer Network is composed of several basic elements that include hardware and software components, namely:
1. Hardware Components
Personal Computer (PC), Network Interface Card (NIC), cable and network topology.
2. Component Software
Network Operating Systems, Network Adapter Drivers, Network Protocols.

A. Network devices

1. Repeater
Function to receive signals then pass back the received signal with the same power. With the repeter, the signal from one computer to another computer that is located far apart.

2. Hub
Its function is similar to a repeater hub consists of only a few ports, so that the hub is also called multiport repeter. Repeaters and hubs work at the physical layer so it does not have knowledge about the destination address. Although the hub has several ports, but still make use of the broadcast method of sending signals, so that if one port is busy then the other ports have to wait if you want to send a signal.

3. Bridge
Functioning like a repeater or hub, but more clever because it works on data link layer that has the ability to use the MAC address is in the process of sending frames to the destination address.

4. Switch
Functions the same as the bridge just switch consists of several switch ports so-called multiport bridge. With these capabilities if one of the busy port on the switch then the other ports can still function. But bridges and switches can not forward IP packets addressed other computers in different logical network.

B. Type, Type of Cable and Wiring

Each type of cable has the ability and their specifications are different, because it made the introduction of cable types. There are several types of cables that are widely known, namely twisted pair (STP UTPunshielded twisted pair and shielded twisted pair), coaxial cable and fiber optic.

1. Thin Ethernet (thinnet)

Thin Ethernet or thinnet have advantages in terms of the relatively cheaper cost compared to other types of cabling and the installation of components easier. The length of thin wire coaxial/RG-58 between 0.5 - 185 m and a maximum of 30 computers terhubung.Kabel coaxial type is widely used among amateur radio, particularly to transceivers that do not require a large power output.
To be used as network devices, coaxial cable of this type must comply with the IEEE 802.3 10Base2 standard, where the average diameter of about 5mm and usually black or other dark color. Each device (device) is connected with a BNC T-connector. The cable type is also known as thin Ethernet or thinnet. Coaxial cable of this type, such as the type RG-58 A / U or C / U, if implemented with Tconnector and terminator in a network, must follow the rules as follows:
• Each end of the cable are 50-ohm terminator.
• The maximum length of cable is 1,000 feet (185 meters) per segment.
• Each segment is a maximum of 30 devices connected to the network (devices)
• Network cards can simply use an onboard transceiver, do not need additional transceiver, except for the repeater.
• Maximum there are 3 segments connected to each other (populated segments).
• Each segment should be equipped with one ground.
• minimum length between the T-Connector is 1.5 feet (0.5 meters).
• Maximum cable length in one segment is 1.818 feet (555 meters).
• Each segment has a maximum of 30 devices connected.

2. Thick Ethernet (Thicknet)

With a thick Ethernet or thicknet, the number of computers that can be connected in a network will be more and the distance between the computers can be enlarged, but the cost of procurement is more expensive wiring and installation is relatively more difficult compared with thinnet. In Thicknet transceiver used to connect each computer to the network system and connectors used are type DIX connector. Maximum transceiver cable length 50 m, Thick Ethernet cable maximum length 500 m with a maximum 100 transceiver connected. Coaxial cable of this type is specified by IEEE 802.3 10Base5 standard, where the cable has an average diameter of 12mm, and is usually given a yellow color; cable type is commonly referred to as thick Ethernet or standard Ethernet, or simply abbreviated thicknet, or even referred to as yellow cuman cable.Kabel this Coaxial (RG-6) when used in the network have the specifications and rules as follows:
• Each end must be terminated with 50-ohm terminator (recommended using
terminator that has been assembled, instead of using a single 50-ohm resistors 1 watt, because the resistor has a fairly wide voltage dissipation).
• Maximum of three segments with the equipment connected (attached devices) or a populated segments.
• Every network card has an additional transmitter (external transceiver). Each segment is a maximum of 100 network devices, including repeaters in this case.
• Maximum cable length per segment is 1640 feet (or about 500 meters).
• Maximum distance between the segment is 4920 feet (or about 1500 meters).
• Each segment must be grounded.
• Rarely a maximum between the tap or pencabang from the main cable to the device (device) is 16 feet (5 meters). Rarely minimum inter-tap is 8 feet (2.5 meters).

Smoking Dangers

2008-04-01T18:44:00.000+07:00

Cigarettes, in fact what the benefits of smoking? Why the increasing number of people who smoke, despite the many studies that say that smoking is very dangerous. In some article I read about smoking, secondhand smoke can cause air pollution that can disrupt our world who are dying of this. And smoking also can cause addiction. Many of us underestimate the dangers of smoking on our health and with certainty to convince the people that forbid we could stop at any one time. The reality of high school students 1-5 cigarettes per day, 70% are still smoking 5 years later.
A little note for active smokers:
The younger the person smokes, the greater the chances become heavy smokers as adults.
These are some small note about the dangers of smoking:

1. Cigarette smoke contains 40 cancer-causing chemicals, small amounts of toxins such as arsenic and cyanide, and more than 4,000 other chemicals.

2. When smoking is exploring a series of chemicals the body's vital organs such as brain, lungs, heart and blood vessels that can cause cancer and addiction.

3. Cigarette smoke also contains Carbon Monoxide which if inhaled can replace the function of oxygen in the blood cells. In addition, smoking also can numb the senses of taste and smell us so that we can no longer feel the delicious food as usual.

4. The key ingredients in cigarettes is nicotine. Nicotine can stimulate chemicals in the brain that can lead to addiction. Chemicals

Eiiits .... not only that the dangers of smoking, we are not smoking can also harm us. For people who do not smoke referred to as passive smoking. There are some dangers of passive smoking for smokers are:

1. Dangers of passive smoking for the smoker can also cause lung cancer and heart disease when we inhale cigarette tarsebut asp.

2. For passive smokers who suffer from respiratory diseases and heart disease, as well as parents, they are more susceptible to cigarette smoke.3. In addition, for children who become passive smokers are also at risk of ear infections, pneumonia, and bronchitis.

4. Finally, for mothers who smoked during and after pregnancy are at risk of 3x greater cause of the baby dying from sudden death syndrome.

Content Bioethanol

2008-03-15T13:51:00.000+07:00

Bioethanol is a fuel that is now being developed in the world because the world's fossil fuel is running low.Now all countries are competing to produce bioethanol.Did you know that bioethanol is also has the exhaust gases.Some of these exhaust gases also have a positive impact and also negative.Here are some of the content of these Bioethanol:

1.CARBON monoxide (CO)
CO emissions Bioethanol-fueled cars E3; 35% ppm, E10; 1.38%, and E20; 0.76%.That means emissions of CO would fall in line with the addition of Bioethanol.The lack of waste that can trigger cancer compounds that can improve the quality of air freshness.Excess carbon dioxide that is inhaled can bind to hemoglobin in the blood that interfere with concentration.

2.NITROGEN OXIDES (NOX)
Unfortunately, decreasing the amount of CO emissions are not accompanied by impairment of nitrogen oxides (NOx).Nitrogen oxide exhaust triggers global warming on higher Bioethanol reached at E3 1272 ppm, 1078 ppm on E10, and 1870 ppm on E20.

3.HIDROKARBON
By E20, Hydrocarbon emissions 1% lower than pure gasoline.The double impact of low exhaust hydrocarbons.Positively impact human health.Hydrocarbon trigger danger of intelligence disorders, reproductive health, and headache symptoms in humans.

Places Tourism in Indonesia

2008-02-26T14:24:00.000+07:00

you want to tour? So the answer is Indonesia.everything you want is in Indonesia.Indonesia do have a lot of places we will discuss pariwisata.disini some tourist bagusuntuk diIndonesia that you visit: 1.Lake Toba in the Nort Sumatra Lake Toba is a volcanic lake with a length of 100 kilometers and 30 kilometers wide, located in North Sumatra Province, Indonesia. In the middle of this lake there is a volcanic island called Samosir Island. Lake Toba has long become an important tourist destination in North Sumatra, Bukit Lawang addition and Nias, attract domestic and foreign tourists. 2.Tangkuban Perahu in the West Java Tangkuban Parahu or Tangkuban Perahu is one of the mountain located in the province of West Java, Indonesia. Approximately 20 km to the north of Bandung, with a lush carpet of pine trees and tea plantations in the surrounding mountains have Tangkuban Parahu high altitude 2084 meters. The shape of this mountain is the center of eruption Stratovulcano who moved from east to west. Rock type issued by the eruption of lava and most of the sulfur, a mineral which is issued sulfur sulfur, a mineral that was issued when the mountain is not active sulfur vapor. Boat Tangkuban area managed by the Corporation of Forestry. The average temperature is 17oC daily at noon and 2 oC at night. Tangkuban Perahu have Dipterokarp forest hill, forest Upper Dipterokarp, Montane forest, and forest or forest Ericaceous mountain. 3.Mount Ijen Mount Ijen is an active volcano located in Banyuwangi regency, East Java, Indonesia. This mountain has a height of 2443 m and has erupted four times (1796, 1817, 1913, and 1936). To climb this mountain may depart from Bondowoso or from Banyuwangi. Located 3 km from Paltuding and is one of the largest and most beautiful crater in Indonesia in the form elip with size 960 mx 600 m and a depth of about 200 m with a volume of 63 million m3 of water has a pH very acidic (pH 0-2) and water color vary each time, which is dominated by the color green or blue. To reach the lip of the crater is quite difficult because it must be reached by climbing a fairly steep slopes (40 ° - 60 °) with a distance of ± 27 meters, making it suitable for visitors who love a challenge. Ijen Crater Lake has a unique and distinctive charm, namely the occasional greenish water of the lake surface was covered by smoke billowing sulfur in the lake. In addition, the lake surface elevation is reached more than 2384 meters above sea level, when viewed from close range the lake is as if boiling, because of the large air bubbles from the bottom of the lake. This is possible because of volcanic activity beneath the lake. The bubbles are sometimes followed by a blast of steam and gases that endanger, so visitors should be careful when watching this lake up close. 4. Berastagi Berastagi is a major tourist destination in Tanah Karo is situated at an altitude of about 4594 feet above sea level and surrounded by mountain ranges, has the cool air of the beautiful expanse of farm fields, broad, green. Berastagi is a tourist destination that has a complete facility in Tanah Karo, such as hotels, restaurants, golf and others until the hotel can charge relatively affordable. Brastagi also known by the nickname of "Passion Fruit & Orange Sweet." From the city of "Passion Fruit & Orange Sweet" Brastagi, visitors will enjoy spectacular views over the mountains that are still active, namely Sibayak mountain hiking and mountain Sinabung.Untuk Sibayak takes approximately 3 hours drive and we can enjoy the beautiful scenery these mountains or take 3 to 4 hour trip in the woods to see the good in it's natural wealth of flora and fauna in the surrounding forest. In addition to fruits, also known as a producer Brastagi various kinds of vegetables, fruits and flowers. In the city Brastagi implemented several tourism events such as "Feast of Flowers & Fruit" and the cultural festival "Mejuah-juah Party" held every year. Tanah Karo is also a tradition that has been done that is hereditary "Work Year" held every year by the Karo people who lived in the area or who have migrated to come back to the township that has a family relationship to each visit and stay in touch.

Mercury There Everywhere

2008-01-01T11:59:00.000+07:00

Mercury-Based on reports compiled reductions are feasible Norden, organizational cooperation countries Normandy, in 2010, each year 1200-2900 merkurium ton steam released into the atmosphere due to human activities.

Mercury vapor can be started from anything. From an energy saving lamps in your room is broken, your television remote control batteries are exhausted, and anti-fungal paint the walls of your home.
Yes, mercury is closer than Minamata Bay in Japan is appalling the world in the 1950s. The case of mercury pollution by Chisso Corporation, a manufacturer of chemical fertilizer, carbide, petrochemicals, and plastics, in Minamata, Japan, the world has been aware of the risks of mercury waste to dispose of a direct nature.

At least 1629 people died because of toxicity of methyl mercury waste discharged into Minamata Bay who infiltrated the fishermen catch fish and shellfish which then turned into a body of people who eat fish and shellfish Minamata Bay.

Mercury accumulation eventually damage the human central nervous system, causing various symptoms of nerve damage known as "Minamata Disease". Content of mercury in the body of a mother "inherited" the baby fed, to produce children with disabilities and / or suffering from cerebral palsy. The total number of victims of mercury pollution by Chisso Corporation of more than 30,000 people.

Based on reports the United States Environmental Protection Agency cited the International Persistent Organic Pollutants Elimination Network, mercury and adversely affect brain development and nervous system. Mercury can reduce the ability of thinking, memory, attention, mastery of language, motor skills outcomes, and skills of visual space.

Repeating Minamata

However, mercury poisoning do not have to wait-made industrial waste into rivers and oceans. The official program of United National Environmental Programme, Desiree Navaez, disclose the fact how much mercury vapor is everywhere. Metals that melt at a temperature of -38.87 degrees Celsius it evaporates in normal room temperature ranges from 25 degrees celsius-38 degrees celsius.

Mercury is an element that can not be created, at the same time can not be destroyed. "Natural mercury content of the average 0.05 mg per kg in the earth's crust. In nature, mercury is released in the process of weathering crust of the earth or volcanic activity. However, human activity has increased the release of mercury in the atmosphere. Burning coal in steam power plants, cement production, oil and gas processing, all of which release mercury into the atmosphere, "said Navaez.

Mercury vapor as dangerous as methyl mercury are disposed of Chisso Corporation into Minamata Bay. "In the air, mercury vapor is persistent, not easily broken down by nature. Mercury vapor will carry over to where the wind blows, carried thousands of miles and across the continent, "said Navaez in Jakarta, Tuesday (3 / 8).

Mercury vapor in the atmosphere will last between 6 months and 18 months, then whole somewhere. When decays, mercury can enter the food chain, especially entering the food chain of marine and aquatic ecosystems, just as occurred in Minamata Bay.

"Mercury will accumulate in marine life that eventually consumed by humans. In the long run, the mercury in the body accumulates in the intestine, brain, heart, lung, liver, and kidney. Content of mercury in the body will result in skin rashes, irritability, sweating, difficulty sleeping, extreme pain, and irritation, "said Navaez.

Because long-lasting mercury vapor in Earth's atmosphere, experts say, mercury is a global pollutant. On June 7 to 11, delegates 121 countries have followed the early negotiations to restrict the use of mercury globally. Deputy Assistant Waste Management of B3 and B3 of Mines, Energy, and Oil and Gas Ministry of Environment (MoE) Ratio Ridho Sani said, Indonesia supports the use restriction plan merkurium through international agreements.

"However, the restriction should be noticed that the interests and capabilities of developing countries. Indonesia supportive, but asked for the application of the principle of common but differentiated responsibilities (business together, but with different responsibilities), "said the ratio ..

More vulnerable

Many facts show that mercury is dangerous. However, the metal thus play a role in civilization. His ability to bind other metals mercury makes an important actor in the process of coating metal (amalgam), bleaching, also finishing metal processing. The gold miners in gold mining hundreds of people use mercury to purify gold from worthless materials.

Director tells of Bali Fokus Yuyun Ismawati hair test test participants Intergovernmental Negotiating Committee shows Mercury restricted, the body of citizens of developing countries tend to precipitate more mercury than the body of citizens of developed countries. "From the hair test to 50 delegates Stockholm talks that have all been tested hair merkurium contain between 95 and 2600 micrograms per kilogram of body weight. Facts pulling, hair developing country delegates have merkurium content higher than developed country delegations hair, "said Yuyun.

The content of mercury in hair delegation developed countries ultragram average 669 per kilogram of body weight (ug / kg), while the mercury content in hair delegations of developing countries on average 1182 ug per kg.

Mercury is indeed close to our daily life. Mercury thermometers still sold in many pharmacies in Indonesia despite the existing electrical thermometer. Sensitivity to temperature and its nature as a good conductor of electricity makes an essential component of mercury and fire alarm sensors in the ceiling space and office space.

Most energy-efficient electric lights in Indonesia is a safe mercury lamp used for the jar is not broken. Superkuat batteries in the remote control or mobile phone you were using mercury.

Cat antifungal may contain mercury and mercury evaporate continuously in the home and pollute the earth. Mercury is used in amalgam fillings and even cavities in our mouths. Also to preserve the vaccine for children under five are now beginning to be abandoned despite the use of preservatives that are safer.

All this led to mercury vapor in developing countries, like Indonesia, potentially higher than developed countries.

"We never know what we should do if the energy saving lamps in our homes out of useful life. Batteries that can no longer be used should be disposed of where? There is no obligation for the manufacturer of energy saving lamps, for example, to withdraw the product bermerkuri out of useful life, "said Yuyun.

Ratio explained, Indonesia began to clean up to reduce mercury pollution in their own country. On 3 August, the Ministry of Environment held a Roundtable Discussion Mercury Management in Jakarta. The plan, reduced use of mercury will start from the health sector.

"The health sector is sensitive to the mercury issue. In fact, it is a strategic sector to initiate restrictions on mercury compared to other sectors, "said ratio.

Then, what about the mercury pollution in our homes? While only time we own that can prevent it while waiting for the government is prepared to take care of it.

Save wear-skimp battery, keep your energy saving lamps in your home so as not to rupture. Be careful choosing wall paint, dental fillings, also vaccine immunization.
