Potensi Gas Rumah Kaca (CH4 Dan CO2) di Tempat Pemrosesan Akhir (TPA) Sampah Piyungan, Bantul, D.I Yogyakarta

Abstract

Solid waste is one of the sector that contribute in generating greenhouse gasses. Solid waste dumped in landfill will decompose and produce gas emission of methan (CH4) and carbondioxide (CO2). The purpose of this research is to find out the potential of emission and specific emission factor of gasses of methan (CH4) and carbondioxide (CO2) in landfill of Piyungan and provide recommendation in the form of mitigation and adaptation effort based on the amount of greenhouse gasses emission in Piyungan. Calculation of emissions of methan (CH4) and carbondioxide (CO2) in Piyungan’s Landfill using the IPCC (Intergovernmental Panel on Climate Change). method Tier 1 in 2006. On the Tier 1 estimation of greenhouse gass emission using most of the default IPCC parameter data. For the calculation of specific emission factors, the activity data using the number of population served by Piyungan’s landfill. The result showed the value of emissions of methane (CH4) and carbondioxide (CO2) in 2012 until 2016 increased about 39,465%, while the estimated average value of specific emission factor for methane (CH4) and carbondioxide (CO2) for the past 5 years is 5,874 Gg CH4/ppl and 17,768 Gg CO2eq/ppl. Mitigation and adaptation measures that can be recommended are socialization techniques of 3R, optimization of composting from source and landfill, and improvement of landfill operation by shortening the time of waste closure and utilizing methane gas that has been collected.
