Biokonversi Limbah Pangan Menggunakan Larva Black soldier fly (BSF) Menjadi Pakan Marmut (Cavia porcellus).

Abstract

Limbah pangan yang tidak dikelola berpotensi mencemari lingkungan, sehingga diperlukan alternatif pengelolaan melalui biokonversi menggunakan larva Black Soldier Fly (BSF). Penelitian ini bertujuan mengonversi limbah pangan rumah makan dengan larva BSF, menganalisis hasil biokonversi, dan memproduksi pakan marmut sesuai SNI 8509:2018. Hasil penelitian menunjukkan reduksi limbah 82,5%, indeks reduksi limbah 5,9% per hari, dan laju konsumsi segar 20,8 mg/larva/hari. Uji proksimat menunjukkan kadar abu 8%, lemak 8%, dan protein 19% sesuai standar, sedangkan kadar air 13% dan serat kasar 13% belum memenuhi standar. Pakan substitusi 15% tepung BSF menghasilkan sisa pakan terendah 0,62±0,92 g, bobot akhir marmut tertinggi 381 g, dengan kenaikan rata-rata 99 g/ekor/bulan. Penilaian panelis menunjukkan skor corak bulu tertinggi pada perlakuan B yaitu menggunakan pelet substitusi BSF. Hasil ini membuktikan bahwa tepung BSF berpotensi sebagai bahan pakan alternatif bagi marmut sekaligus mendukung pengelolaan limbah pangan berkelanjutan.

Unmanaged food waste has the potential to pollute the environment, so an alternative management is needed through bioconversion using Black Soldier Fly (BSF) larvae. This study aims to convert restaurant food waste with BSF larvae, analyze the bioconversion results, and produce guinea pig feed according to SNI 8509:2018. The results showed a waste reduction of 82.5%, a waste reduction index of 5.9% per day, and a fresh consumption rate of 20.8 mg/larva/day. Proximate tests showed that ash content of 8%, fat 8%, and protein 19% were in accordance with the standard, while water content of 13% and crude fiber 13% did not meet the standard. The 15% BSF flour substitution feed produced the lowest feed waste of 0.62±0.92 g, the highest final weight of guinea pigs was 381 g, with an average increase of 99 g/head/month. Panelist assessments showed the highest fur pattern score in treatment B, which used BSF substitution pellets. These results prove that BSF flour has the potential as an alternative feed ingredient for guinea pigs while also supporting sustainable food waste management.
