Storage period is one of the factors which affect the physical and chemical quality of the stored material. This study aimed to determine the effect of storage period on the chemical quality of livestock concentrate biscuits con- taining Indigofera and sengon. Four periods of storage period were arranged in a completely randomized design which was repeated 5 times. The storage period consisted of 0, 7, 14 and 21 days. The chemical qualities observed in- cluded moisture and ash content, crude protein and crude fiber. The results showed that storage period significantly reduced the moisture content of concentrate biscuit, while the ash content, crude protein and crude fiber were not affected by storage period. It was concluded that the concentrate biscuits containing Indigofera and sengon could be stored for up to 21 days with good chemical quality.

Black soldier fly (BSF) larvae have cellulosic activity in the presence of bacteria in their intestines, organic waste recycling activities using the bioconversion method, bioconversion as a change of organic waste into biomass thro- ugh a fermentation process involving living organisms. Generally, the organisms that play a role in this bioconver- sion process are bacteria, and Hermetia illucens larvae as bioconversion agents of fermented water hyacinth are combined with fruit waste and used as a growing medium. Hermetia illucens larvae with feeding treatment P0 = 100% fruit waste, P1 = fruit waste 25 % + 75% fermented water hyacinth, P2 = 50% fruit waste + 50% fermented water hyacinth, P3 = 75% fruit waste + 25% fermented water hyacinth, larvae used are 6 days old, for all treatmen- ts using 50g Larval mass weight. The results showed that. P3 = 75% fruit waste + 25% fermented water hyacinth produces the highest average weight of the final mass of larvae, namely 124.62 (gr), average feed consumption of 72.72%, average ECD and WRI values of 10.98% and 10.38%. The mixing level of water hyacinth and fermented fruit waste in treatment 3 showed an effective result as a growing medium for Hermetia illucens larvae.
