Abstract

Black Soldier fly larvae is an insect capable to convert organic waste into body biomass. The purpose of this research was to determine the productivity, mass balance of the consumption process, and content of protein and fat of prepupa which has a potency as a livestock feed. This research used 6-day-old larvae, they were fed with cassava skin that has been smoothed with a variety of feeding doses: 12.5; 25; 50; 100; and 200 (mg / larvae / day) with ratio of feed and water 2: 1. The results showed that the feeding of 200 mg / larva / day produced the best larval growth with biomass productivity of 1.54 mg / day, residue yielded of 67.1 mg / day. The organic waste was convertion into larvae biomass. In this study, approximately consumption process scale is feed successfully converted to biomass 2.77%, metabolism 6.98%, and 90.24% residue. Protein content is 25.7%. It can be concluded that the larvae are able to convert organic waste into high protein biomass and potentially being used as a livestock feed. This research acts a model to predict mass balance of substrates for feed. The benefit of this research is the science approach used in this study that can be used as a reference by researchers and the community to determine the biomass production of an organism.

Highlights

Black Soldier fly (BSF) is an insect that spreads in tropical and warm areas, which is around 450 NL to 400 SL (Diener et al 2011)
Black soldier fly are commonly found in warm areas that is protected from sunlight, for example on the periphery house or under shady trees
Black soldier fly larvae are classified as detritivor organisms because they consume organic materials derived from living things such as fruits, leaves, carcasses, and human waste (Kim et al, 2011)

Summary

Introduction

Black Soldier fly (BSF) is an insect that spreads in tropical and warm areas, which is around 450 NL to 400 SL (Diener et al 2011). Black soldier fly are commonly found in warm areas (about 20 - 30 ) that is protected from sunlight, for example on the periphery house or under shady trees. The life cycle of black soldier fly consists of eggs, larvae, prepupa, pupa, and adult (Diener et al, 2011). Black soldier fly larva (BSFL) is a polyphagus (can consume all types of food) and able to consume large amounts of food quickly and efficiently than other types of flies (St-Hilaire et al 2007). Black soldier fly larvae need a dark spot at a temperature of about 10 - 20 and a relative humidity of 60-75% with adequate food supply (Diener et al 2009; Zheng et al, 2012; Li et al, 2011a.b)
