In a small-scale farming implementing cyclical economy, farm organic waste is a problem of nutrient and energy management where if not utilized will in turn be the source of pollution and wasted nutrient potential that can be converted into valuable by-products. Black soldier fly larvae Hermetia illucens L. is used to convert the organic waste of spinach Amaranthus tricolor L. and rehydrated chicken manure Gallus domesticus L. to produce larvae biomass and larval residue in an attempt of reducing and reutilising organic farm waste. Five different organic waste composition are given as feed to the H. illucens larvae age 5-21 days ad libitum with five replications, which are 100% spinach, 75% spinach-25% chicken manure, 50% spinach-50% chicken manure, 25% spinach-75%chicken manure, and 100% chicken manure. In an attempt to reduce and convert organic farm waste, H. illucens larvae in treatment C produces the best biomass from the parameters of total biomass produced, growth rate, food conversion ratio, waste reduction index, digestibility, conversion efficiency of digested feed, and proximate. From larval residue, treatment C is observed to produce the best larval residue from the parameters of proximate values
