Studi Inventarisasi Emisi Gas Rumah Kaca (CO2, N2O, CH4) di PT. Pertamina Hulu Energi Ogan Komering Sumatera Selatan

Abstract

PT. Pertamina Hulu Energi Ogan Komering (PT. PHE OK) is a company engaged in oil and gas exploration and production activities. In its operational activities, PT. PHE OK as an energy sector produces greenhouse gas emissions (CO2, N2O and CH4), both from stationary and mobile sources. The purpose of this study is to calculate the greenhouse gas emission burden, calculate the percentage contribution of the emission burden generated and determine the alternative reduction of greenhouse gas emissions at PT. Pertamina Hulu Energi Ogan Komering. The method of calculating the emission burden for stationary sources used is the Intergovernmental Panel on Climate Change (IPCC) Tier 1 method, while the method of calculating the emission burden for mobile sources used is Intergovernmental Panel on Climate Change (IPCC) Tier 2 and for fugitive sources using Intergovernmental Panel on Climate Change (IPCC) Tier 1 Based on the results of the study, it can be seen that the largest contributing pollutant gas in mobile sources is dominated by CO2 emissions, namely 98.28%, followed by N2O emissions of 1.6% and CH4 of 0.1%. Then in immobile sources, CO2 is also dominated by 99.9%, followed by CH4 emissions of 0.06% and N2O of 0.04%. Meanwhile, fugitive sources are dominated by CH4 emissions caused by natural gas, followed by CO2 and N2O emissions. One alternative to reducing greenhouse gas emissions is to increase Green Open Space around the company's location with the required Green Open Space area of 115.5 km2, and the planned plant type is trembesi tree which is able to absorb 3.03% emissions per year in the study area.
