Indonesia which is a net-exporter in of fuel oil has turn become a net importer of oil since 2009. It is ironic because it occurs at the world's oil price is unstable and tends to increase. It is time for Indonesia to develop alternative energy sources and bio-diesel oil from the seeds of  nyamplung (Calophylum inophylum L.). The purpose of this researh was to determine the magnitude of the yield of oil from the seeds of the produced by the level of maturity. The raw and the riped yamplung seeds was used in this research. The results showed that the yield of oil in ripe seed is 24.01% and the raw one is 19.17% . Acid number and iodine number of oil based on the average maturity are 37.51 g / ml and 3094.14 g / ml for the ripe fruit, and 37.18 g / ml and 3421.32 g / ml for the raw fruit.Keywords: nyamplung, maturity, yield, oil, fuel.

The energy sector holds a crucial strategic importance for development and its sustainability. However, the energy reserves in Turkey are insufficient for the increasing energy demand. For this reason, the need for alternative energy sources has emerged. The fact that fossil fuels used in energy production will be exhausted and their damaging effects on the environment has made it inevitable for the world to use renewable energy. In Turkey, the following are the main energy sources used in electricity production: hydraulic sources, brown coal, natural gas, coal and fuel oil. The use of renewable energy sources in electricity production has shown a considerable development in the world over the past few decades. However, these energy resources have yet to be exploited to any large extent in Turkey. In this chapter, the range of potential renewable energy resources available for electricity production in Turkey will be analyzed in order to determine the necessary technical substructure to make these renewable energy resources more attractive.

Population growth and industrial development cause oil fuel consumptionincreases, so availability will thinning because it cannot be renewed. So toovercome that the government issued Presidential Decree No.10 of 2006concerning Development of Vegetable Fuels. Biodiesel is one of themrenewable alternative energy sources which are processed from vegetable oilswith use alcohol and NaOH as catalysts through the transesterificationprocess. Used cooking oil is one source of vegetable oil that can used as rawmaterial for making biodiesel through the process transesterification. But theuse of used cooking oil directly without through the adsorption process willaffect the quality of the biodiesel produced. The purpose of this study is todetermine the effect of adsorption time used cooking oil for the quality ofbiodiesel produced from used cooking oil. This research aimed to know thereis or no effect of odsorption time of cooking oil using the clay towardsbiodiesel quality. Object of this research used cooking oil which is adsorptedwith varieties time of adsorption was 0 hour (Control), 12 hours, 36 hoursand 48 hours. Based on the result of research showed that adsorption timehas effect towards quality, where high adsorption time was 12 hours. Qualityof biodiesel has been suitable with SNI. The quality was dencity 0,860 gr/cm3,water degree 0,035% vol, flame coordinate 170oC and acid number 0,71 mgKOH/g oil % the result of biodiesel 55,29%.

Subject. The article discusses limited sources of energy nowadays and an ongoing survey of new ones. I focus on fuel and energy complexes worldwide and in Russia. Objectives. The study is to analyze the future use of alternative energy sources in the fuel and energy complex nationwide and worldwide. I review the existing energy sources of the fuel and energy complex in the global and regional markets, specifically the alternative ones. Methods. The study relies upon methods of statistics, analysis and systems approach. Results. The article demonstrates that the fuel and energy complex strongly depends on the current situation in the energy resource market, which is difficult to forecast. If we continue relying on traditional energy resources, we get exposed to some risks affecting the sustainable development of the economy. Russia should diversify the power engineering sector by developing alternative energy sources. The article sets forth the economic rationale for alternative sources and key steps Russia shall make. Conclusions and Relevance. Considering the current situation in the energy balance, alternative energy is what any advanced society seeks for, being supported by manufacturers, governmental institutions, and researchers, though low profitability and high infrastructure costs impede its development. In Russia, these challenges are even more palpable. However, even now Russia is able to find alternative energy solutions. In addition to advantages of alternative energy, which is globally proclaimed, they will also help Russia diversify and update the economic system.
