Abstract

TPA Ngipik Kabupaten Gresik menerapkan sistem controlled landfill yang berpotensi menghasilkan emisi gas rumah kaca (GRK) secara signifikan dari berbagai aktivitas operasionalnya, terutama melalui dekomposisi anaerob sampah organik yang menghasilkan gas metana (CH4). Penelitian ini bertujuan untuk mengukur dan menganalisis besarnya jejak karbon dari kegiatan pengelolaan sampah dan lingkungan di TPA Ngipik, mengidentifikasi faktor kontributor terbesar, serta memberikan rekomendasi pengurangan emisi melalui skenario pengelolaan sampah yang lebih efektif. Penelitian dilakukan menggunakan pendekatan IPCC Tier-1 dan Tier-2 dengan batasan analisis pada sumber emisi Scope 1 dan Scope 2. Data primer diperoleh melalui observasi lapangan, pengukuran langsung, dan wawancara, sedangkan data sekunder bersumber dari laporan operasional TPA, pedoman IPCC, dan regulasi terkait. Analisis mencakup aktivitas penimbunan di landfill, pengolahan di TPST, pengomposan di rumah kompos, konsumsi bahan bakar kendaraan dan alat berat, konsumsi energi listrik, serta pengolahan air lindi. Hasil penelitian menunjukkan total jejak karbon TPA Ngipik pada kondisi eksisting sebesar 107.976,15 ton CO2e/tahun, dengan kontribusi terbesar berasal dari area landfill sebesar 107.483,97 ton CO2e/tahun (99,5%), diikuti TPST 270,95 ton CO2e/tahun (0,25%), dan rumah kompos 221,23 ton CO2e/tahun (0,21%). Faktor dominan penyebabnya adalah dekomposisi anaerob pada zona landfill aktif yang menyumbang 99,12% total emisi TPA, akibat 98,54% sampah masih langsung ditimbun. Upaya mitigasi dievaluasi melalui tiga skenario: kondisi eksisting (Skenario 1), optimalisasi TPST (Skenario 2), dan optimalisasi TPST disertai efisiensi rumah kompos (Skenario 3). Skenario 2 merupakan yang paling efektif dengan total emisi 104.124,78 ton CO2e/tahun, menurunkan jejak karbon sebesar 3.851,37 ton CO2e/tahun atau 3,57% melalui peningkatan reduksi sampah di TPST dari 1,23% menjadi 28,73%.

Ngipik Landfill in Gresik Regency operates under a controlled landfill system that generates significant greenhouse gas (GHG) emissions from various operational activities, particularly through the anaerobic decomposition of organic waste that produces methane (CH₄). This study aims to measure and analyze the carbon footprint from waste management and environmental activities at Ngipik Landfill, identify the key contributing factors, and provide emission reduction recommendations through more effective waste management scenarios. The study was conducted using IPCC Tier-1 and Tier-2 approaches, with the analysis boundary limited to Scope 1 and Scope 2 emission sources. Primary data were collected through field observation, direct measurement, and interviews, while secondary data were obtained from landfill operational reports, IPCC guidelines, and relevant regulations. The analysis covers activities including landfill disposal, processing at the Materials Recovery Facility (MRF/TPST), composting at the composting house, fuel consumption of vehicles and heavy equipment, electricity consumption, and leachate treatment. The results show that the total carbon footprint of Ngipik Landfill under existing conditions is 107,976.15 ton CO2e/year, with the largest contribution coming from the landfill area at 107,483.97 ton CO2e/year (99.5%), followed by the MRF at 270.95 ton CO2e/year (0.25%), and the composting house at 221.23 ton CO2e/year (0.21%). The dominant factor is the anaerobic decomposition in the active landfill zone, which accounts for 99.12% of total landfill emissions, driven by the fact that 98.54% of incoming waste is still directly landfilled. Mitigation efforts were evaluated through three scenarios: existing conditions (Scenario 1), MRF optimization (Scenario 2), and combined MRF optimization with composting efficiency improvement (Scenario 3). Scenario 2 proved most effective, yielding total emissions of 104,124.78 ton CO2e/year, a reduction of 3,851.37 ton CO2e/year (3.57%) by increasing the waste reduction rate at the MRF from 1.23% to 28.73%.
