Evaluasi Biomassa dan Kandungan Nutrisi Magot (Hermetia illucens) Pada Media Budidaya yang Berbeda

Abstract

Feed is a very important factor in the cultivation of fisheries and is the largest component, which is around 50-60% of production. One of the efforts to reduce feed costs is by using maggot as an alternative substitute for fish meal and can be given in the form of fresh to fish. Maggot (Hermetia illucens) is an organism originating from a black soldier egg known as a decaying organism because it consumes organic materials. The advantage of maggot is that it has anti-microbial and anti-fungal properties, so it does not cary a disease agent. Maggot has a crude protein content of 30-45%, so it is very potential as an alternative feed for fish. The purpose of this study is to determine the effect of maggot culture media on biomass and maggot nutrient content. This activity was carried out at the Fisheries Laboratory of the Lampung State Polytechnic. The tools and materials used were maggot eggs, Palm Kernel Meal (PKM), fish waste, coconut cake and bran, digital scales, basins. The research method used was an experimental method with a Completely Randomized Design (CRD) consisting of 4 levels and 3 repetitions, with treatment: A = PKM media, B = fish waste media, C =coconut cake media, D = bran media. The parameters observed were maggot biomass, maggot content and also maggot fatty acid. The results showed that the optimal media for biomass and maggot nutrient content were fish waste ( catfish fillet waste), which was maggot biomass of 435.2, with a protein content of 44.58%, 4.89% fat, crude fiber 8.02%, linolenic acid 1.98 and linoleic acid 3.67 Keywords: Biomass, cultivation media, maggot,nutrition content
