Renewable energy is needed as an alternative energy source. One of the implementations of renewable energy is the Solar Power Plant (PLTS). PLTS is a component that uses solar cells to convert solar energy into electrical energy. Unfortunately, the output power of this solar cell depends on the intensity of the light which causes the output power to enter the load to be unstable. Sometimes the PV power decrease because of the shading effect. From this problem a converter is needed to keep the system output voltage. The converter used in this research is the zeta converter. This Zeta converter can operate like a buck boost converter. The output of the system used is not stable. So that to stabilize it requires good control. In this paper using PI controller to control this system in order to keep the output system stable. 3. The error generated using the PI Control on the system is only 0.34%.

Abstract The purpose of this study is to design a Photovoltaics (PV) stand-alone system for a residential load in Bunaken Island using HOMER (Hybrid Optimization of Multiple Energy Resources). Bunaken Island, the case study location, is a popular tourist spot in North Sulawesi, Indonesia. This island is facing the issue of limited access to electrical energy from the grid. The design and techno-economic analysis in Bunaken island leveraged HOMER software. This software was developed by National Renewable Energy Laboratory (NREL). Furthermore, the results suggested that the techno-economical PV stand-alone system in Bunaken Island could be developed as alternative energy to support electricity as energy security issued for Indonesia.

This research aims to make prototype battery from star fruit as alternative energy. In everyday life electrical energy used comes from fossils that will be used up in a period of time. Therefore, it takes an alternative energy that can reduce the use of non-renewable energy. We utilize star fruit vegetable as an alternative energy used as a replacement battery, where the battery can be used as energy. Battery of star fruit has a power of 1 Volt and almost equivalent to the battery in the market that is 1.5 V voltages.

In recent years, several factors such as environmental pollution which is caused by fossil fuels and various diseases caused by them from one hand and concerns about the dwindling fossil fuels and price fluctuation of the products and resulting effects of these fluctuations in the economy from other hand has led most countries to seek alternative energy sources for fossil fuel supplies. Such a way that in 2006, about 18% of the consumed energy of the world is obtained through renewable energies. Iran is among the countries that are geographically located in hot and dry areas and has the most sun exposure in different months of the year. Except in the coasts of Caspian Sea, the percentage of sunny days throughout the year is between 63 to 98 percent in Iran. On the other hand, there are dispersed and remote areas and loads far from national grid which is impossible to provide electrical energy for them through transmission from national grid, therefore, for such cases the renewable energy technologies could be used to solve the problem and provide the energy. In this paper, technical and economic feasibility for the use of renewable energies for independent systems of the grid for a dispersed load in the area on the outskirts of Isfahan (Sepahan) with the maximum energy consumption of 3Kwh in a day is studied and presented. In addition, the HOMER simulation software is used as the optimization tool.

Biogas Energy

Processing of agricultural and livestock waste produces biogas which is then used by the community to substitute natural gas energy and substitute electricity for clean water supply and produce organic fertilizer for farming purposes. This research was conducted using descriptive methods, by describing how to treat agricultural and livestock waste. Then a quantitative approach is used which aims to describe or explain the conversion of biogas energy into electrical energy. Biogas has good prospects as an alternative energy substitute for non-renewable energy in Indonesia which is experiencing an energy crisis which is characterized by increasingly scarce and high fuel prices which have an impact on the higher costs of generating electricity. In the Ganjar Farmers-Farm Group, the use of biogas by using goat / sheep dung is very potential, from 300 goats / sheep has the potential to produce electrical energy of 32.4 kWh / day. Most of the power plants that supply the Pati Regency region still use energy sources made from non-renewable energy materials. The depletion of fuel for these non-renewable plants, power plants with renewable fuels are absolutely necessary.
