Abstract

Peningkatan emisi gas rumah kaca (GRK) menjadi salah satu penyebab utama pemanasan global dan perubahan iklim. Sektor limbah berkontribusi sekitar 3% terhadap total emisi GRK nasional, termasuk aktivitas pengolahan air limbah rumah sakit. Proses pengolahan air limbah menghasilkan emisi GRK berupa CO2, CH4, dan N2O yang berasal dari proses pengolahan, konsumsi daya listrik, dan penggunaan bahan kimia. Penelitian ini bertujuan untuk menghitung besaran emisi GRK pada IPAL Rumah Sakit X Kab. Lamongan dengan kapasitas 347 bed serta menentukan alternatif prioritas untuk menurunkan emisi yang dihasilkan.
Perhitungan emisi dilakukan berdasarkan pedoman IPCC 2019 Refinement to the 2006 Guidelines for National Greenhouse Gas Inventories dan berdasarkan scope 1 dan scope 2. Data yang digunakan meliputi kualitas dan debit air limbah, konsumsi daya listrik, serta penggunaan bahan kimia. Emisi dihitung dalam satuan kgCO2e/tahun dan selanjutnya digunakan sebagai dasar penyusunan alternatif penurunan emisi yang kemudian dianalisis menggunakan metode Analytical Hierarchy Process (AHP) untuk menentukan prioritas penerapan alternatif.
Hasil penelitian menunjukkan bahwa nilai rata-rata emisi GRK yang dihasilkan dari IPAL Rumah Sakit X Kab. Lamongan sebesar 216.899 kgCO2e/tahun yang merupakan akumulasi emisi scope 1 dan 2 . Kontributor terbesar berasal dari aktivitas penyisihan nitrogen pada proses pengolahan biologis dengan kontribusi sebesar 52,46% serta penggunaan listrik pada blower sebesar 31,73%. Unit biofilter aerobik line 1-3 merupakan kontributor produksi emisi tertinggi dibandingkan unit lainnya, yakni rata-rana 231.321-266.871 kgCO2e/tahun. . Dari ketiga alternatif tersebut, dianalisis menggunakan metode AHP untuk menentukan prioritas alternatif yang dapat diterapkan. Hasil dari analisis menunjukkan bahwa alternatif optimasi frekuensi drain sludge menjadi prioritas utama dengan skor 0,47. Sedangkan urutan kedua dan ketiga, yaitu optimasi aerasi melalui pembersihan sparger (0,34) dan penggunaan inverter (0,19).

Greenhouse gas (GHG) emissions have become one of the primary drivers of global warming and climate change. In Indonesia, the waste sector accounts for approximately 3% of total national GHG emissions, with hospital wastewater treatment plant (WWTP) representing one of the contributing emissions. GHG of the wastewater treatment, including carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O) are generated through biological processes, electricity consumption, and chemical used reaction. Therefore, this study was conducted to quantify GHG emissions of the WWTP at Hospital X in Lamongan Regency, with capacity 347 beds, and to identify the most appropriate mitigation strategy for reducing these emissions.
GHG emissions were estimated using the “2019 Refinement to the 2006 IPCC Guidelines for National Greenhouse Gas Inventories” and classified into Scope 1 and Scope 2 emissions. The analysis was based on wastewater quality and flow rate, electricity consumption, and chemical consumption data. Total emissions were expressed in kgCO₂e/year and subsequently used to develop emission reduction alternatives. These alternatives were then evaluated using the Analytical Hierarchy Process (AHP) to determine their implementation priority.
The results revealed that the WWTP generated an average total GHG emission of 216,899 kgCO₂e/year, representing the combined emissions from Scope 1 and Scope 2 sources. The largest contributor was nitrogen removal during biological wastewater treatment, accounting for 52.46% of total emissions, followed by electricity consumption of the aeration blowers, which contributed 31.73%. The aerobic biofilter units (lines 1–3) were identified as the highest emission sources among all treatment units, producing approximately 231,321–266,871 kgCO₂e/year. Based on the emission inventory, three mitigation alternatives were proposed optimizing sludge drainage frequency, improving aeration performance through regular sparger cleaning, and installing inverter-based blower control systems. The AHP results ranked optimization of sludge drainage frequency as the highest-priority alternative with a weight of 0.47, followed by aeration enhancement through sparger cleaning (0.34) and inverter installation (0.19).
