Abstract

Kabupaten Jember masih menghadapi permasalahan stunting dengan prevalensi sebesar 34,9% yang salah satu penyebab utamanya adalah rendahnya asupan protein hewani dan kalsium pada balita. Di sisi lain, MBS Darul Falah di Desa Cakru memiliki unit budidaya dan produksi fillet lele frozen yang menghasilkan limbah ikan hingga 60–70% dari berat total, berupa kulit, tulang, duri, dan kepala ikan. Limbah tersebut belum dimanfaatkan secara optimal, padahal bagian-bagian ikan lele memiliki kandungan protein dan kalsium yang tinggi serta berpotensi diolah menjadi pangan bergizi. Kondisi ini menunjukkan pentingnya inovasi pemanfaatan limbah lele berbasis zero waste yang bernilai ekonomi sekaligus mendukung pencegahan stunting. Kegiatan ini bertujuan mengembangkan model kewirausahaan zero waste berbasis limbah lele, meningkatkan kapasitas santri dan mitra budidaya dalam pengolahan limbah menjadi produk pangan bergizi, serta menghasilkan inovasi produk tinggi protein dan kalsium untuk mendukung pemenuhan gizi balita. Metode pelaksanaan meliputi pelatihan teknis pengolahan limbah lele menjadi produk seperti tepung tulang, kerupuk kulit, dan abon kepala lele, pendampingan kewirausahaan, penerapan SOP produksi higienis, serta uji kandungan gizi dasar. Hasil kegiatan menunjukkan peningkatan keterampilan mitra dan dihasilkannya produk pangan bernilai gizi dan ekonomi. Simpulannya, pemanfaatan limbah lele berbasis zero waste berpotensi menjadi solusi berkelanjutan untuk pemberdayaan ekonomi pesantren sekaligus mendukung upaya pencegahan stunting.

Abstract

The growth of laundry businesses has led to an increase in the volume of wastewater containing detergents, organic matter, suspended solids, and phosphates, posing a potential environmental pollution risk if discharged without treatment. This study aimed to analyze the effects of varying the thickness of filtration media—composed of silica sand, bagasse, and activated carbon—and varying operational times on the reduction of pH, COD, TSS, and phosphate levels in laundry wastewater. A PVC-based gravity-flow (down-flow) filtration reactor was operated using three media composition variations: activated carbon-dominant (P1), bagasse-dominant (P2), and silica sand-dominant (P3), with operational times of 30, 60, and 90 minutes. The results indicated that variation P1 achieved the highest COD reduction efficiency (36.98%), while variation P3 yielded the greatest TSS reduction (98.18%). The pH levels of all effluents met the quality standards established by East Java Governor Regulation No. 52 of 2014. However, COD levels failed to meet the threshold across all treatments, and phosphate levels increased due to leaching from the bagasse media. Multiple linear regression analysis revealed that filtration media thickness significantly influenced effluent pH and TSS, whereas operational time did not have a significant partial effect on any of the parameters. As this filtration system could not simultaneously meet all quality standards, further treatment is required to enhance its effectiveness.
