Abstract
PT Petrokimia Gresik merupakan penghasil pupuk terlengkap di Indonesia. Salah satu produk yang memiliki kapasitas produksi tertinggi adalah pupuk NPK Phonska. Proses produksi pupuk NPK Phonska menghasilkan emisi gas buang dari proses dryer, scrubber, absorber, serta bahan bakar fosil sebagai pembangkit listrik. Emisi yang dihasilkan dari proses produksi tersebut dapat memberikan efek terhadap pencemaran udara baik lingkup pabrik maupun global. Penelitian ini bertujuan mengidentifikasi dampak lingkungan yang ditimbulkan dari proses produksi pupuk NPK Phonska melalui pendekatan Life Cycle Assessment (LCA), dengan sistem Gate to Gate. Tahap pertama penelitian adalah menghitung beban emisi, selanjutnya merekapitulasi data bahan baku, energi, produk, dan emisi. Data tersebut dimasukkan pada tahap life cycle inventory dalam software SimaPro 9.0.0. Berdasarkan hasil LCI, dilakukan identifikasi dampak pada tahap life cycle impact assessment dengan metode TRACI 2.1 dan CML 1992. Hasil identifikasi dampak merujuk pada penentuan titik hotspot proses dan hotspot dampak. Langkah selanjutnya adalah menentukan alternatif perbaikan berdasarkan studi literatur dan saran dari pihak PT Petrokimia Gresik. Adapun hasil perhitungan beban emisi pada proses produksi pupuk NPK Phonska sebesar 36.059.112 kg CO2/th, 7.260 kg CH4/th, 4.600 kg N2O/th, 5.653,81 kg NH3/th, 965,8 kg F-/th, dan 82.783,6 kg partikulat/th. Berdasarkan hasil running software SimaPro dengan metode TRACI 2.1, yang menjadi titik hotspot proses adalah unit pre-neutralizer dengan hotspot dampaknya ecotoxicity. Sedangkan dengan metode CML 1992, yang menjadi titik hotspot proses adalah unit dryer dengan hotspot dampaknya energy resource. Alternatif perbaikan yang dapat diterapkan ada 3 yaitu mengganti dengan peralatan baru, melakukan penjadwalan preventive maintenance, dan perbaikan isolasi pada pipa uap, pencegahan kebocoran serta perbaikan perilaku.

PT Petrokimia Gresik is the most complete fertilizer producer in Indonesia. One of the products that has the highest production capacity is NPK Phonska fertilizer. The production process of NPK Phonska fertilizer produces exhaust emissions from the process of dryer, scrubber, absorber, and fossil fuels as electricity generation. Emissions resulting from the production process can have an effect on air pollution both in the scope of the plant and globally. This study aims to identify the environmental impact caused by the production process of NPK Phonska fertilizer through the Life Cycle Assessment (LCA), with the Gate to Gate system. The first stage of the study is calculate the load emissions, then recapitulate data on raw materials, energy, products, and emissions. The data is entered at the life cycle inventory stage in software SimaPro 9.0.0. Based on the results of LCI, impacts were identified at the life cycle impact assessment stage using TRACI 2.1 and CML 1992 methods. The results of impact identification refer to the determination of the process hotspot and impact hotspot points. The next step is to determine alternative improvements based on literature studies and suggestions from PT Petrokimia Gresik. The results of the calculation of emissions load in the production process of NPK Phonska fertilizer amounted to 36.059.112 kg CO2/year, 7.260 kg CH4/year, 4.600 kg N2O/year, 5.653,81 kg NH3/year, 965,8 kg F-/year, and 82.783,6 kg of particulates/year. Based on the results of running SimaPro software with the TRACI 2.1 method, the point of the hotspot process is the pre-neutralizer unit with the hotspot impact is ecotoxicity. Whereas with the 1992 CML method, the point of the hotspot process is a dryer unit with the hotspot impact is energy resources. There are 3 alternative repairs that can be applied, replacing with new equipment, scheduling preventive maintenance, and repairing insulation on steam pipes, preventing leakage and improving behavior.
