Indonesia is one of the developing countries that need a large supply of energy. Currently, Indonesia that has around 239 million people need electricity as much as 142.53 TWH with a capacity of national power around 34 giga watts. And in the upcoming year 2025, estimated that electricity demand will rise to 100 giga watt. Fact energy needs was not offset by the availability of energy sources that we owned the land. As an illustration, the actual oil Indonesia is estimated to reach only 18 more years, production of gas reserves estimated at 61 years, and reserves of coal about 147 years. In fact, 54% use of renewable energy in Indonesia comes from petroleum, 26.5% from natural gas, and 14% comes from coal. Therefore, the need to source alternative energy to replace the energy generated by fossil fuels and natural gas. Why Nuclear? reactorPenggunaan and utilization of alternative energy other than fossil fuels is a must considering the limited source of energy is. Among the alternative sources of energy can be sources of renewable energy (Renewable) such as water, wind, sunlight and tidal water. Unfortunately, the utilization of renewable energy is still very limited and small in scale. PLTA is less possible built in Java. Sunlight energy (solar) terkendala with expensive solar panel (solar cell) and small because the energy produced is not continuous. Geothermal Energy (Geothermal) akan potential but not always in place the necessary geographic constraints). Energy derived from wind is also difficult to remember the expected wind speed and direction in the equatorial regions are not always the same. Nuclear energy is an energy alternative to the relatively large potential to substitute fossil energy. At this time, regardless of new exploration, world uranium reserves will be sufficient to meet world energy needs up to 100 years. And with the technology and processing, breeding (on a certain type of reactor), even up to 3600 will be sufficient future. Alternative energy that will replace the position of fossil energy also must be efficient and environmentally friendly. A nuclear reactor will produce heat and moisture will produce high bertekanan to play the power turbine. Thermal energy generated by burning 1kg pure uranium-235 is about the size of the 17 billion Kkal, or the equivalent of burning 2.4 million kg of coal. Related to efficiency, the cost of electricity production is a PLTN approximately 3.5 - 4.5 cents per kWh to U.S. dollars. Much cheaper than the price of electricity is now estimated at 7 cents per kWh to U.S. dollars. Security and Safety Issues When talking about nuclear, which is then usually be a war, weapons, and accidents. Of course this is reasonable because the world still haunt the Chernobyl reactor accident in the Union Sovyet, reactor accident Three Miles Island in the U.S., and destroyed the city leburnya Hiroshima and Nagasaki because the atomic bomb on Japan. But then what is that opinion is no good in nuclear energy? Islam has given the understanding that everything on earth is not for human kemaslahatan. About how and to what is used by humans, it is submitted to the individual or collective human itself. "O people, remember God will favor you. Is there a creator besides Allah who can give rezki to you from the heavens and the earth? There is no god but He: then are you turned away (from ketauhidan)?" (Faathir (35): 3) Security-related issues such as the use for nuclear weapons, the United Nations, through the IAEA (International Atomic Energy Agency) was set in the NPT (Non-Proliferation Tractat), which use nuclear for peaceful purposes. And Indonesia is one of three countries-the first two, namely Norway and Australia, which signed the CSA (Comprehensive Safeguard Agreement). In addition, there are technical things that can not be tolerated related to making nuclear weapons. Plutonium and uranium that can be used as nuclear weapons have to be The level (pen.: Enrichment - refinement) in the top 80%. Meanwhile, a commercial nuclear reactor can operate with a uranium enrich-in of 5%, and The maximum limit for a commercial reactor is set IAEA of 20%. Another related issue is the nuclear safety. Is a must for the IAEA to keep the use of nuclear energy in the world to stay safe and in accordance with the objectives of the peace. Therefore, there are many prerequisites before a specified of a nuclear reactor. As a small example such as the geology, the history of disaster (earthquake, tsunami, etc.) for several hundred years back, human resources readiness, and so on. Standard building a nuclear reactor even far above the standard for building the military. And even after the stand, the IAEA will continue to periodically monitor the reactor is. About the dangers of nuclear accidents, it has been anticipated since the making of reactor design itself. PLTN have a design security and anticipating the accident flake. Design a safety PLTN include: Safeguard safety first; PLTN designed, built, and operated in accordance with very strict conditions, a high quality and sophisticated technology. Second layer of safety; PLTN equipped with system security / safety that is used to prevent and overcome the consequences of accidents that may occur during the age PLTN. And a third layer of safety; PLTN equipped with additional security system, which can be estimated to occur in a PLTN. The majority of the nuclear reactor in the world at this time belong to the generation II nuclear reactor that has operated safely and securely (cat.: Reactor at Chernobyl is a reactor type RBMK-1000 reactor is classified in the generation I). And to the future, the nuclear reactor that is used in PLTN generation III and III + is more economical and more protected from the possibility of error caused the accident or natural disaster. About waste, nuclear waste processing has become a serious attention from the nuclear expert since the first. No radioactive waste contamination to the natural surrounding, well water, land and air. Water (sea / river) which is used as cooling medium for some types of reactor, and not carry oxygen-radioactive substances in pendinginannya cycle. Gas issued by a PLTN very small (about 2 milicurie / year) so it does not impact the environment. On PLTN, most of the waste generated waste activity is low (70 - 80%). While the activity level of waste generated from the recycling of waste. Handling of radioactive waste in general, includes three things: 1.) Reduce the volume way evaporasi, insenerasi, kompaksi (pressed). 2.) Forms a stable process (both physical and chemical) for ease in transportation and storage. 3.) Storing the waste has been processed in a diisolasi. HR readiness In the preparation of development PLTN, BATAN has formed a partnership with various parties in foreign countries, especially with countries in the development of advanced PLTN, such as the United States (Westinghouse, General Electric, the US-doe), Canada (AECL, Nordion and AECB), South Korea (KAERI, KHNP), Japan (JAERI, JAEA, MHI), France (CEA, AREVA) and Russia (ROSATOM). Forms of cooperation include joint study, familiarization with the design of the NPP, training, on the job training, Managerial and technical issues and exchange of information. In addition, three research-scale reactor that was built in Indonesia (one of the oldest built in 1965) has contributed not a little to the community through the field of medicine, agriculture, animal husbandry, industry, etc.. And for this, has never been an accident that resulted in the victim lives or very severe on the research reactor facility. This proves that the human resources that have and will continue to grow the human resources is a powerful and teruji. Conclusion Anywhere in the world, the decision to build nuclear installations for the purpose of fulfilling energy needs will ultimately be at the social-political skup. Ready technology at a state-owned. Not with the exception of Indonesia. History has proven how the west and east of the country continues to try to drop by Soekarno as more than 'can not be controlled by any block, under the leadership of Indonesia, he began to have the potential of dangerous nuclear technology. In the end, be under the Soekarno western conspiracy. Indonesia and the potential nuclear slowly subside under the leadership successor. Technology, nuclear technology is the most sophisticated and advanced at this time. Who has this technology, he can disejajarkan with developed countries. In addition, the need for energy is cheap, efficient and friendly environment is needed at this time, and Indonesia to the front in particular. Is a step that 'berani'-and-nekad', a country of Indonesia pitch more than 50% of energy from oil price fluctuation is in the world market. Because if it has a good faith, the government must take bold steps to rescue the firm's energy resources of Indonesia. In addition to preparation in the field of technology, especially pencerdasan people associated with the peaceful use of nuclear for energy solutions and is a great PR that can not be ignored. Government Regulation (PP) of Nuclear Reactor License No. 43/2006 has been at least a little to prove seriousness Government. However, keberjalanannya still need to be monitored and be under guard. So that there is no longer a concern akan energy needs for children-our grandchildren.
