The Biodegradation of Black Soldier Fly (Hermetia illucens) on Tofu Dregs and Bread Wastes

---

If left untreated, biowaste is one of the contributors to environmental problems and
greenhouse gas production. Treatment options such as bioconversion using insects may have
beneficial and affordable outcomes for managing biowaste. Decomposing insect, such as the black
soldier fly (BSF), whose larvae are capable of converting food waste into high-value biomass. Which
then could be an alternative source of protein for human and animal consumption. Both tofu dreg and
bread waste are in constant supply and contribute to the bio-waste problem in Indonesia. Black soldier
fly larvae were fed three rearing substrates consisting of a combined formulation of a tofu dreg (TD)
and bread waste (BW) done in triplicates. Formulated rearing substrates consist of TD:BW ratios of 1:1
or 1:2, and 2:1. In an addition, two controls consist of 100% BW and 100% TD. The substrates were
supplemented to one hundred five-day-old larvae maintained in temperature 28-30°C and 70%±5
moisture content. Determination of developmental time, survival, waste conversion efficiency, yield,
biomass and growth performance. Based on all parameters investigated, 2:1 ratio was the best
performing TD:BW rearing substrate. TD control performed the best, it resulted in a comparable or
higher than 2:1 ratio. However, the TD control had the lowest BSFL total solids record. Thus, combining
TD with BW increased the BSFL performance in comparison to rearing in an individual substrate types.
