A. The role of natural SCIENCE AND TECHNOLOGY
1.MATERI
Of human life requires material, both biotis and non-biotis. Biotis material things of life is a protein, while the material is nonbiotis objects do not survive as oxygen, stone, until the clothes we wear everyday. Objects are processed through technology, such as iron can be processed into another vehicle or object needs to manusia.i
2.ENERGI
The use of energy in the more widespread human life, in industry, transportation, and even households with the use of tools, electronic equipment such as AC, refrigerator, etc. (the form of electricity). Berwuwjud energy in various forms, namely the form of heat, movement (mechanics), light, chemical, nuclear, etc.. Forms of this can be changeable, for example, heat energy can be mechanical energy. This change occurred with the way the water into steam. Steam heat bertekanan the higher the rotor of a turbine. Movement turbine can be used for various purposes. Mechanical energy can also be changed into another form of energy, namely electricity, where the result of playing akan dynamo generated electricity. Electrical energy can also be modified chemical energy that is the way stream direction to the flow of electricity in chemical substances, for example, in penyepuhan. Similarly, the chemical energy can be changed back into electrical energy, light energy or the other. For example, on a stone battery, chemical energy that flowed diahsilkan if the bulb then will light energy. Pad the other cases, chemical energy can diunbah a fireworks explosion (heat and light energy). Ii
From the description above, it can be concluded that energy is eternal, or does not have the energy will be lost, but metamorphosis occurs energi.Berikut described several forms of energy used in daily life, such as electricity and nuclear energy that has been used by the state-negra maju.iii
a.Energi Electricity
Next will be discussed tendang power plant and its use for the equipment electronics.
1) Power Water Power
The principle of working PLTA are as follows:
From a dam, the water flowed through a tunnel by using the tool controller. Tunnel was constructed so that water falling from a height of 100 m or more to change the potential energy into mechanical energy is large. Water on the other end of the tunnel on hold by the water turbine mdan with encouragement eair, the turbine rotates. Turbine rotation is used to rotate the generator or engine power. Electricity generated by the generator and set tekanannya changed by a transformer. From here, power flowed to the regions that need. Before flowed to households, derived through voltasenya transformer so that more electricity generated in accordance with the needs of the household. Indonesia is usually used in the voltage 220 volt or 110 volt. AIT further out of the turbine that can be used for irrigation pertanian.iv
2) Power Diesel Power
Principle, almost the same as the PLTA, with the generator power, but the power of this diesel engine is used. Diesel engine chosen as an alternative because it can be placed according kebituhan, while diesel fuel is a much cheaper price than the price premium.v
On this type of power, electrical energy from chemical energy of combustion of diesel oil. This is an example of change in chemical energy into mechanical energy, and energy into electricity. Diesel oil itself actually comes from the times of ancient fossil life, while the fossil form of conservation of energy radiation from the sun through asimilasi. From here we can see the flow of energy changes that occur in nature. vi
3) Power Nuclear Power
Before discussing about the power nbuklir, will be discussed first on nuclear energy or nuclear energy itself. According to the theory of Rutherford and Bohr, atoms consist of electrons, electrons that encircle the core atom and had a negative power. vii
Core atom consists of a proton and a positive cargo netron the netral.Atom be the most simple atom is hydrogen (H) consisting of a proton and a core sebgai electrons that encircle the core of the skin. Atom is a simple Helium (He), which consists of 2 fruits and 2 fruits proton netron and 2 as the core electrons as fruit skins. Atom-atom of the atom that has a skin flake and core atomnya larger. For example uranium atom with a 7 layer skin electron atom with the number of 92, essentially consisting of 92 proton and 146 netron.viii
Nulir energy is energy that arises due to splitting the core atom. In general, the atom is parsed atom has a nucleus of a large atom, such as uranium. The principle of splitting the atom is to shoot with the results netron-shedding substances of other radioactive substances. Core atom split into parts of the small issue with a great energy and netron-netron the bersal of the core is broken. Nuclear energy is the energy that comes from the binding eneggi atom. Energy that is out beru [pa hot, hot in the reactor is absorbed by a liquid heat penyerap then flowed into the water so the water is boiling, and evaporate. This is the steam which is then used to drive a steam turbine generator power the next. So nuclear energy is not directly converted into electrical energy, but changed into heat energy and steam into energy. ix
Current outbreak defusi the atom called the nucleus (disintegration). Nuclear energy can also arise on the way, the two core tergabungnya atomic nucleus to be larger. For example, the two energy of hydrogen (Deuterium) is the core Helium (He ³) plus a netron. This event is called a fusion core. Core fusion produces enormous energy that can not be used for the hydrogen bomb. Until now, humans can not control the energy produced from fusion reactions for peaceful purposes. x

b.Komunikasi
One of the needs of human life is to communicate between each other. To the knowledge of nature with the technology was donated to us all, such as print media, telegrafi, television and radio. Means of communication that are now introduced in developed countries, is a telecommunications satellite with a combined radio and television. With this tool, people can talk with talking opponent, so as if they look in the face each other. World of communication has developed rapidly with the aid of satellite telekomukiasi, where the first shock has occurred in 1962 with the Radio and TV broadcasts that can be received in the same time around the world separated by the Atlantic ocean, namely Europe, and the United States. Technology of communication with the growing of all the information can be delivered over the overlooks. People can quickly find out what events are going the other dibelahan earth. Distance of thousands of kilometers is not the gulf between two people or more who want to communicate. Dimungkinkannya reception with broadcast radio and television overlooks this earth, then the changes occur in the development of society caused by the rapid exchange of culture. The spread of knowledge that facilitate rapid mutual understanding among people around the world to become great.
