POTENSI LARVA Hermetia illucens SEBAGAI PEREDUKSI LIMBAH INDUSTRI PENGOLAHAN HASIL PERIKANAN

Abstract

AbstrakLimbah organik dari industri pengolahan ikan bisa menjadi masalah serius jika tidak ditangani dengan baik, karena jumlahnya yang terus meningkat setiap tahun. Padahal kandungan nutrisinya masih tinggi, terutama kadar proteinnya. Proses biokonversi bahan organik dari limbah diharapkan mampu menjadi solusi permasalahan limbah industri dan bisa meningkatkan nilai tambahnya. Biokonversi menggunakan larva serangga Hermetia illucens mempunyai banyak keunggulan dibandingkan proses konversi lainnya. Tujuan dari penelitian ini adalah untuk mengetahui kemampuan larva dalam mengurangi limbah dari industri perikanan. Limbah yang digunakan ialah kepala ikan tuna. Dengan variasi perlakuan jumlah kepala tuna sebagai pakan larva yaitu 60, 80 dan 100 mg/larva/hari. Larva yang digunakan sebanyak 200 ekor dan dilakukan pengulangan perlakuan sebanyak 3 kali. Waktu pengamatan dan pemeliharaan larva selama 19 hari, kemudian dihitung substrate reduction, waste reduction index (WRI), bobot larva serta kandungan protein dan lemak dari larva. Hasil pengamatan menunjukkan bahwa jumlah pakan optimum ialah 60 mg/larva/hari, meliputi parameter substrate reduction 77,09%, WRI 4,06%/hari, bobot larva 72,59 mg, kandungan protein 25,38 % (berat basah) dan kandungan lemak 6,85% (berat basah). Berdasarkan hasil tersebut bisa disimpulkan bahwa larva memiliki potensi sebagai agen pengurai limbah industri pengolahan perikanan.

Though the content of nutrients in the waste is still high, especially protein content. The bioconversion process of organic matter from the waste is expected to be able to overcome the problems of industrial waste and increase its added value. Bioconversion using insect larvae Hermetia illucens has many advantages than other conversion processes. The purpose of this study was to determine the ability of larvae in reducing the waste fishery industry. Waste used in this study was head of the tuna, with feeding rates of 60, 80 and 100 mg/larva/day. 200 larvae were used in each treatment and 3 replications. Observation time and culturing of larvae was 19 days then calculated substrate reduction, waste reduction index (WRI), the weight of larvae and protein and lipids content. The result of observations showed that feeding rate 60 mg/larva/day give optimum on parameters. The substrate reduction was 77.09%, WRI 4.06 (% / day), the weight of larva was 72.59 mg. Protein content 25.38 % (wb) and lipids 6.85 % (wb). According to that result, it could be to concluded that larvae have potential as an agent of reducing of waste fishery products.

Solid palm oil as poultry feed and growth media of Black Soldier Fly (BSF) larvae

“…The nutritional value of solid palm oil after being overgrown with larvae decreased. This is in line with that reported by [11][12].…”

“…Various growth media were made to grow BSF or Hermetia illucens larvae [11][12]. Various growth media that have been tested include palm kernel cake [13,14,15], organic waste from industrial and urban waste [16], cow dung [17], chicken manure, tofu dregs [18][19], tuna processing waste [11][12], etc. BSF larvae are easy to grow on various media because they have a wide pH tolerance [14].…”

“…Thus, BSF larvae are the mainstay in generating alternative feed supply independently by utilizing industrial waste through a bioconversion process, converting organic waste into simple compounds. The ability of BSF larvae to perform bioconversion is due to the presence of several bacteria in its digestive tract [12]. BSF larvae have great potential as an alternative to prove protein sources.…”
