Abstract
Electrical energy is produced by objects that are electrically charged. Static electric charges will cause electrical potential energy, while dynamic electric charges will cause electric current and magnetic energy. The size of the population and the diversity of activities in metropolitan cities in Indonesia have resulted in general problems in urban infrastructure services, such as current waste problems. Waste is defined as solid waste consisting of organic substances which are considered useless and must be managed so as not to endanger the environment and protect development investment. Landfill gas is a gas produced by solid waste which is disposed of in landfills. The waste is piled up and pressed mechanically and the pressure from the layer above it. Because the condition becomes anaerobic, the organic matter decomposes and gas landfill is produced. This gas is increasingly gathering to be slowly released into the atmosphere and if it is not used or handled properly it will be dangerous because it can pollute the air and the atmosphere of the earth. The largest gas content found in LFG is methane by 45 - 60% and followed by carbon dioxide by 25-50%. Landfill gas is produced from the decomposition of organic waste material.
Highlights
This time the backbone of energy in Indonesia still depend on fossil energy
Waste that will be produced by landfill gas which will be used for the main fuel of the combustion process to produce electricity
Gas is channeled by pipes that are available directly on landfills that are directly directed at the engine to do the combustion process to produce electrical energy
Summary
This time the backbone of energy in Indonesia still depend on fossil energy. The use of landfill gas generated from the Waste Disposal Site (TPA) as an electric energy generator is called a Waste Power Plant (PLTSa). Waste management in Indonesia mostly still uses sanitary landfill techniques by utilizing methane gas that arises in waste and channeled via wells and pipes to generate electricity at the site of the final disposal site (TPA). If not going to do the construction of sanitary landfills, the Regency and City must immediately utilize other technologies such as MBT (Mechanical Biological Treatment) followed by AD or Thermochemical to reduce the amount of old waste already in the landfill while processing environmentally friendly waste into electricity and obtain organic fertilizer as an additional product
