Abstract

Konsumsi ikan nasional meningkat setiap tahunnya dengan kenaikan dari tahun 2020 ke 2021 sebesar 1,10%. Praktik produksi pakan ikan memiliki dampak lingkungan langsung yang terkait dengan emisi ke udara, air, dan tanah seperti pemanasan global dan eutrofikasi. Proses produksi pakan ikan dibagi menjadi beberapa tahap yang meliputi unit intake, fine grinder, mixer, press, post pellet, dryer, cooler, sieveter, bagging off, dan boiler. Besar dampak lingkungan yang dihasilkan dari kegiatan produksi pakan ikan dapat dianalisa dan diidentifikasi dengan metode Life Cycle Assessment (LCA).

Metode Life Cycle Assessment (LCA) mencakup empat tahap yaitu goal and scope definition, life cycle inventory (LCI), life cycle impact assessment (LCIA), dan intepretasi data. Penelitian ini terbatas pada proses produksi pakan ikan (gate to gate) berdasarkan kategori dampak metode ReCiPe 2016 (H) dengan faktor karakterisasi midpoint. Faktor kategori dampak dalam penelitian didapatkan dengan mengklasifikasikan data inventory. Selanjutnya menentukan rekomendasi program perbaikan lingkungan yang didasari dari hasil kajian LCA, tinjauan pustaka, hasil diskusi dengan pihak perusahaan, dan Analytical Hierarchy Process (AHP).

Hasil analisis kajian LCA produksi pakan ikan yaitu setiap produksi 1 ton pellet ikan akan menghasilkan 10 kategori dampak. Unit proses dan kategori dampak lingkungan yang memberikan kontribusi dampak terbesar (titik hotspot) pada proses produksi pakan ikan terletak pada 2 unit, yaitu unit boiler dengan kategori dampak global warming sebesar 487,58 kg CO₂eq/Ton pellet ikan dan IPAL dengan kategori dampak freshwater eutrophication sebesar 0,00039 kg Peq/Ton pellet ikan. Program perbaikan lingkungan terpilih difokuskan pada pengurangan dampak lingkungan di titik hotspot yaitu program Pengurangan Unburned Carbon di Unit Boiler dengan Multi Layer Coal Sorting yang dapat menurunkan dampak global warming sebesar 5% dan dampak stratospheric ozone depletion sebesar 5%. Sedangkan program Optimalisasi Kinerja MBBR dengan Hydraulic Retention Time yang Ideal dapat menurunkan dampak freshwater eutrophication sebesar 7%.

The national fish consumption increases every year, with an increase from 2020 to 2021 of 1.10%. The practices of fish feed production have direct environmental impacts related to emissions to air, water, and soil, such as global warming and eutrophication. The fish feed production process is divided into several stages including the intake, fine grinder, mixer, press, post pellet, dryer, cooler, sieveter, bagging off, and boiler. Assessment of the environmental impacts generated by fish feed production activities using Life Cycle Assessment (LCA) method.

The LCA method includes four stages: goal and scope definition, LCI, LCIA, and interpretation of data. This research is limited to the fish feed production process (gate to gate) and is based on the impact category method ReCiPe 2016 (H) with a midpoint characterization factor. The impact category factor in research is obtained by classifying inventory data. Subsequently, determining environmental improvement program recommendations based on LCA study results, literature reviews, discussions with the company, and the Analytical Hierarchy Process (AHP).

The results of the LCA analysis on fish feed production indicate that the production of 1 ton of fish pellets generates 10 impact categories. The hotspot in the fish feed production process are found in two units, the boiler unit with a global warming impact category of 487.58 kg CO₂eq/ton of fish pellets and the wastewater treatment plant (WWTP) with a freshwater eutrophication impact category of 0.00039 kg Peq/ton of fish pellets. The selected environmental improvement programs are focused on reducing the environmental impact at the hotspots, namely the Reducing Unburned Carbon in Boiler Units through Multi-Layer Coal Sorting program, which can reduce the global warming impact by 5% and the stratospheric ozone depletion impact by 5%. Meanwhile, the Optimization of MBBR Performance with an Ideal Hydraulic Retention Time program can reduce the freshwater eutrophication impact by 7%.
