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.
