Karakteristik Biokonversi Limbah Organik dalam Gentong Gerabah Menggunakan Larva Black Soldier Fly (BSF)

Abstract

Larva Black Soldier Fly (BSF) yang digunakan sebagai agen biokonversi merupakan salah satu alternatif dalam pengelolaan limbah organik yang mampu mereduksi limbah dengan mudah dan biaya yang relatif murah. Penelitian ini dilakukan guna mereduksi limbah organik yang dihasilkan Pasar Dramaga, mengurangi beban landfill, dan menghasilkan produk berupa kompos dan larva BSF. Tahap penelitian mencakup analisis karakteristik biokonversi limbah organik dalam gentong gerabah, uji tingkat kebauan yang ditimbulkan selama proses biokonversi, serta menganalisis kadar protein larva BSF dan mutu kompos yang dihasilkan. Karakteristik biokonversi limbah organik dalam gentong berupa Waste Reduction (D) sebesar 85,8%, Waste Reduction Index (WRI) sebesar 6,1%/hari, Fresh Matter Consumption Rate (FMCR) 69,3 mg/larva/hari, Dry Matter Reduction (DMR) 51,4%, dan Dry Matter Consumption Rate (DMCR) 35,6 mg/larva/hari. Tingkat kebauan yang ditimbulkan dari proses biokonversi di gentong gerabah cenderung lebih kecil jika dibandingan dengan biokonversi yang dilakukan di biopond. Biokonversi limbah organik menggunakan larva BSF menghasilkan larva BSF dengan kadar protein sebesar 41,0% dan kompos yang sesuai dengan SNI 19-7030-2004 kecuali pada parameter warna, kadar C, dan rasio C/N.

Black Soldier Fly (BSF) larvae used as bioconversion agents are an alternative in organic waste management that can reduce waste easily and at a relatively low cost. This research was conducted to reduce organic waste produced by Dramaga Market, reduce landfill loads, and produce products in the form of BSF larvae and compost. The research phase included analyzing the bioconversion characteristics of organic waste in earthenware barrels, testing for odor disturbances caused during the bioconversion process, and analyzing the protein content of BSF larvae and the compost quality. Bioconversion characteristics of organic waste in earthenware barrel in the form of Waste Reduction (D) 85,8%, Waste Reduction Index (WRI) 6,1%/day, Fresh Matter Consumption Rate (FMCR) 69,3 mg/larvae/day, Dry Matter Reduction (DMR) 51,4%, and Dry Matter Consumption Rate (DMCR) 35,6 mg/larvae/day. The level of odor generated from the bioconversion process in the earthenware barrel tends to be smaller when compared to the bioconversion carried out in the biopond. Bioconversion of organic waste using BSF larvae produces BSF larvae with a protein content of 41,0% and compost according to SNI 19-7030-2004 except for the parameters of color, C content, and C/N ratio.
