Abstract

Inventarisasi emisi gas rumah kaca (GRK) menjadi semakin penting untuk dilakukan terutama pada sektor industri intensif karbon. Salah satu industri intensif karbon tersebut adalah industri ekstraksi sumber daya energi dan mineral. Industri ini merupakan salah satu kontributor utama dalam emisi GRK dan perlu menyusun inventarisasi emisi GRK dalam rangka meningkatkan ketaatan regulasi terkait nilai ekonomi karbon di masa depan. Pada penelitian ini akan dilakukan identifikasi proses penghasilan emisi GRK di unit produksi tambang timah laut, analisis faktor kunci emisi, dan strategi pengurangan emisi. Metode inventarisasi merujuk pada metodologi inventarisasi oleh Intergovernmental Panel for Climate Change (IPCC) 2006. Perhitungan emisi GRK dilakukan pada kegiatan di sektor energi dan limbah. Perhitungan emisi tier 3 menggunakan software COPERT dan estimasi emisi berbasis bahan bakar digunakan pada kegiatan di sektor energi. Metode First Order Decay (FOD) digunakan untuk mengestimasi emisi dari sektor limbah. Analisis kategori kunci dengan approach 1 level assesment dilakukan terhadap hasil inventarisasi. Analisis finansial dilakukan menggunakan kerangka kerja cost-benefit analysis dan pendekatan data envelopment analysis untuk penentuan efisiensi operasional. Hasil inventori menunjukkan besaran emisi untuk kegiatan penggunaan mesin produksi, transportasi laut, transportasi darat, penggunaan listrik, dan pengelolaan limbah secara berurutan yaitu 43517 ton CO2eq (82%), 8768 ton CO2eq (16,5%), 422 ton CO2eq (0,8%), 315 ton CO2eq (0,6%) dan 18 ton CO2eq (0,1%). Kategori kunci yang patut menjadi perhatian adalah penggunaan mesin produksi (mobile combustion) dan navigasi kapal (water-borne navigation). Analisis DEA menunjukkan bahwa terdapat inefisiensi rata-rata sebesar 20,06%. Biaya kesempatan dari inefisiensi tersebut yaitu sebesar Rp60.042.279.023 pada tahun 2021 dan Rp67.844.805.058 pada tahun 2022.

Greenhouse gases (GHGs) emission inventory is becoming more and more important to be done, especially in carbon-intensive industries. One of those industries was energy and mineral extraction. The industry was one of the main contributors in GHG emission and is required to compile a GHGs emission inventory to ensure compliance within the carbon economic value regulation in the future. This study aims to identify GHG emission generation processes, conduct key category analysis, and identify strategies to reduce emissions from tin sea mining production unit. Methodology used in the study refers to inventory methodology of Intergovermental Panel of Climate Change (IPCC) 2006. GHG calculation was conducted to measure emission in energy and waste sector. Tier 3 emission estimation using COPERT software and emission estimate based on fuel consumption was being used to calculate GHG emission from energi activities. The First Order Decay method was used to calculate emissions in the waste sector. Key category analysis on the inventory result was conducted using approach 1 level assesment. Finansial analysis was then carried out with cost-benefit analysis frameworks and data envelopment analysis (DEA) approach to determine the operational efficiency. Inventory result shows that emissions coming from mobile combustion, water-borne navigation, road transport, electricity generation, and waste management activity were 43517 tonnes CO2eq (82%), 8768 tonnes CO2eq (16,5%), 422 tonnes CO2eq (0,8%), 315 tonnes CO2eq (0,6%) and 18 tonnes CO2eq (0,1%), respectively. The key categories identified were mobile combustion and water-borne navigation. DEA analysis shows that the mean inefficiency was 20,06%. Opportunity costs resulting from those inefficiencies were Rp60.042.279.023 in 2021 and Rp67.844.805.058 in 2022.
