Analisis Potensi Sampah Rumah Tangga Sebagai Bahan Bakar Pembangkit Listrik Tenaga Sampah (Pltsa) Di Makassar

Abstract

Final disposal sites (TPA) emit Landfill Gas (LFG) which contains the most methane and carbon dioxide. Methane gas has a warming effect several times stronger in causing global warming compared to CO2, therefore the use of landfill methane gas as fuel for power plants. Before building a Waste Power Plant (PLTSa) in a TPA, a series of studies are needed to determine whether PLTSa is feasible for the TPA to build, one of which is to find out the amount of LFG from the TPA to calculate the potential electrical energy that can be generated.

The purpose of this study is to determine the amount of LFG produced by TPA Tamangapa Makassar City and then to calculate the potential for PLTSa based on the methane gas content in the LFG. The research phase starts with collecting quantitative data in the form of the number of tonnes of waste that goes to the TPA every month. For LFG estimation, LandGEM-v302 software is used which is downloaded from the US Environmental Protection Agency website. Meanwhile, to estimate the potential of electrical energy, the formula is used.

From the research results, the Tamangapa TPA Makassar City sanitary landfill model produces a maximum emission of methane gas of 4,181,760 m3/year, if it is assumed that in 2023 it will start receiving waste. Based on the results of calculations using the formula, the maximum potential for electrical energy generated is 18,988,222 kWh/year.
