The Biodiesel

Fuel oil is a source of energy with the largest current consumption when compared to other energy sources. But the current world fuel crisis. As a result of the depletion of oil and gas supplies are necessary to develop alternative fuels. Alternative fuel is a renewable fuel. Fuel source is derived from green plants that can produce hydrocarbons directly. We can choose a new plant source of high potential to be used as liquid fuels and chemicals.

Biodiesel is also a solution to face the scarcity of fossil energy in the future. Biodiesel is generally a diesel engine fuel made from renewable materials, or specifically a fuel for diesel engines consisting of alkyl esters of fatty acids. Biodiesel can be made from vegetable oils, animal oils or from used cooking oil or recycled. Biodiesel raw materials are potentially large in Indonesia for now is crude palm oil (Crude Palm Oil CPO), palm oil, jatropha oil.

Biodiesel is expected to replace diesel as a base for diesel engines. The advantages of biodiesel is higher cetane number than diesel fuel cetane number that exist today, the flue gas from burning biodiesel is more environmentally friendly, better engine acceleration, and lighter pull.

Development and use of alternative fuels to be one option to meet the demand for fuel is increasing. In addition, alternative fuels have a positive impact such as exhaust emissions are environmentally friendly (especially reducing greenhouse gases), as well as the development of the agricultural industry

Material transfer machine

Material transfer machine is an integral part of mechanical equipment in any modern industry. Mover machine design materials as diverse due to the wide variety and nature of the cargo transferred and the number of grafts that will support the production.

In each company, the overall production process is largely determined by the selection of an appropriate material transfer machine main parameters that proper selection and efficiency of its operations. Thus, a perfect knowledge of the operating characteristics and design of this machine and its design method and its practical application is necessary.

Material transfer machine is one of the tools used to move cargo or area location, departments, factories, construction sites, where the buildup of materials, storage, and unloading. Material transfer machine in practice just to move cargo in large numbers and as well as a certain distance. The distance is only done for thousands of meters of the constant movement between two or more locations connected by the same production activity.

To unload a specific operation, the mechanism of material transfer machine equipped with a special tool holder that is operated by the auxiliary engine or manually. Selection of appropriate material transfer machine and corresponding to each activity above, will improve the efficiency and competitiveness of the event.

Mover machine design based on classified material on:

1. Gear equipment, i.e. machines with lifting equipment group that aims to move the payload in a single batch.

2. Switching equipment, a group that has no engine but move the cargo lifting equipment on an ongoing basis.

3. Equipment and overhead surfaces, namely groups of machines that are not fitted with lifting equipment and usually handle the cargo in a single batch and continuous.

Each group is distinguished by a characteristic engine and specialized areas of usage. Differences in the design group was also determined by the state of load to be handled, the labor movement and the state of the process handling.

Television

The need for information today, demanding the mass media to always access the latest information continuously. Both of the print media, electronic media, the book industry and others. Many new things are growing rapidly due to the emergence of courage in expressing the things that needs to be conveyed to such information. Television as an audiovisual media has its own charm with moving images. Television is one of effective mass media for delivering messages to the audience. Therefore, audiences tend to use television as a means of entertainment, information and knowledge, thus making the information submitted is more interesting and pleasing its audience than other media. Speaking about the content of television, variety shows were presented by television to start a family.

Television as a product of advanced technology, growing rapidly in line with the changing times. Featured broadcasts led to many changes in society, because television has the properties of the medium, ie the messages conveyed have a fairly high power stimulation.

The mass media are extensions of human senses. Television is one of the mass media into a small window to watch the events away from the reach of our senses and which presents an imaginary film passing of time and space

Television has a function as a means of informative, persuasive, motivational, easy and understandable even television is used as an educational medium for coaching young people in order of nation and character building through programs that produced the show from the many television channels.

Television Programs for Children

Private televisions are competing to attract the attention of the audience, by presenting the broadcasts that interest the audience. For in the world of broadcasting laws apply, the number of viewers is directly proportional to income level.

Tight competition for viewers, the broadcast business forcing workers to work extra hard. Due to the positive impressions on television became extremely diverse, ranging from news programs, movies, soap operas, talk shows, quizzes and even gossip was packed into an entertainment program. 

The success of a program for delivering messages to the audience also reflects the success of a number of workers in the back of the screen. The ability of workers in their jobs is dependent on the completeness of the elements of art and technology adaptation. The combination of the two likely produce a quality program and compete with other arts and media technology.

Even programs can be focused on children. However, the program is not just a cartoon child who is merely entertaining. However, many children's program featuring elements of education with an attractive appearance. Since acquiring knowledge, children are not only pegged at school. Dora the explorer, sesame street, etc. are some of the many programs produced children at the television station.

The program is in the form of a child in such a way that uses high creativity to make children interested to see it. If they are interested, then the message in the event program can be easily obtained.

Computer Technology

With the development of computer technology and communication today, a single computer model which serves the entire computing tasks an organization has now been replaced with a set of computers that separate but interconnected in carrying out their duties.

Networking is the connection between multiple computers, peripherals (Such as modems, printers) and other supporting equipment (eg telephone, fax) are interconnected with each other to be used in together. The number of computers, peripherals and other supporting equipment connected can vary from a minimum of 2 (two) units up to several hundred units. Any equipment that is connected to each other in the sense network referred to as a Node.

Physical technology of a computer network can be classified on two (2) parts, namely:

1. Local Area Network (LAN) is a network in which the relationshipthere is only limited to one location, for example in a building. Media liaison that is used is usually a cable.

2. Wide Area Network (WAN) is a separate network by a very wide area, for example between cities or even between countries. Communication that occurs between these networks is done through media phones, satellites, and can also be used transmissions micro.

The benefits to be gained by making computer networks, among others, namely:

1. Provide the opportunity for computer users to use of resources together, such as the use printer or use the shared Internet connection.

2. Optimizing the use of the device so that the achievement of efficiencies such as no need for each computer is equipped with a printer due to the network so that 2 (two) or more computers can use 1 (one) printer.

3. Communication between different operating systems so that unnecessary in a computer network they had to use the operating system the same.
