Characteristic evaluation of organic waste power plant in Bantargebang waste processing plant

Abstract

Bantargebang landfill located in Bekasi is the place where Jakarta dumps its waste. Landfill Gas is a gas produced from biology decomposition reaction process where organic matters are converted into CO2, CH2, ammonia, and hydrogen sulfide. The decomposition will continue aerobically in a short time until the available oxygen lessens. Bantargebang waste processing plant (or TPST in Indonesian) produces an average 6000-7000 tons/day of waste. If the wastes in the waste processing plant are not processed, it could cause undesired environmental pollution. So, with the construction of Waste Power Plant (or PLTSa in indonesian) in Bantargebang waste processing plant could lower the pollution caused by the dumped wastes. Bantargebang's Waste Power Plant have a capacity of 15,6 MW but according to the evaluation result in 2017, the power plant only produces 250 KW electricity. Therefore the purpose of this writing is to evaluate the systems installed in Bantargebang's Waste Power Plant, identify the problem of the decrease in capacity and lowers the level of pollution contained within the area. Based on the evaluation result of attempting to fix the power plant's system using capping and also vertical pipes to collect the landfill gas, it could generates 19,6 MW in the first year and eventually decreased in the following years, until the twentieth year reaches only 0,191 MW. Aside from that, the gas engine itself which was broken needs to be fixed by having its spare part installed and applying a continued maintenance to minimalize future damages.
