(Peer review & similarity) GAS EMISSIONS INVENTORY OF METHANE (CH4) WITH FIRST ORDER DECAY (FOD) METHOD IN TPA PIYUNGAN, BANTUL, DIY

TPA Piyungan is an endpoint landfill disposal of waste that generated from three citizens
(Yogyakarta , Sleman and Bantul). The amount volume of waste that goes on everyday and the
volume of waste that has been buried in landfill, has huge potential of methane. The purpose of this
paper is to inventory emissions of methane (CH4) in TPA Piyungan with First Order Decay (FOD)
method and analyze the alternative utilization technologies of methane (CH4) in accordance with the
conditions of TPA Piyungan. From the results obtained by the First Order Decay (FOD) method,
emissions of methane (CH4) is equal to 6.186 Gg or 6186 tons. The use of alternative methane (CH4)
utilization technologies are such as Landfill Gas (LFG) Flaring, Fuel Cell, and Convert Methane Gas to
Methanol. From the three alternative technologies, Landfill Gas (LFG) Flaring is the technology that
can be most applied in accordance with the TPA conditions.
