STUDI POTENSI PEMANFAATAN GAS (BIOGAS) SANITARY LANDFILL TPA BANYUURIP SEBAGAI SUMBER ENERGI ALTERNATIF GAS MEDIUM BTU DAN PEMBANGKIT LISTRIK (STUDI KASUS KOTA MAGELANG)

Abstract

Biogas is an alternative energy resource come from decomposition organic waste occur in landfill. Waste composition of Magelang consist of 69,65 % organic waste, indicate that Banyu Urip landfill have potency in producing biogas for energy resource. The target of this study is to predict Banyu Urip Landfill’s biogas quantity and its economic potency to be used as alternative energy resources, two of them are medium Btu gas as alternative fuel for industrial boiler machine and as electric power generation. Waste and composition measurement sampling method are done according to SNI-19-3964-1994. And then biogas quantity produced estimated by using Landfill Gas Emission Model (LandGEM) 3.02 version. The result shows Banyu Urip Landfill won’t have potency to exploit as medium Btu gas because its quantity is not enough to support the industrial boiler machine, however, it will have potency to generate 53,09 kW small scale electric power. As small scale electric power generation, Banyu Urip Landfill can get income Rp. 13.804.645.996,00.
