<![CDATA[Hermetia illucens larvae, commonly known as Black Soldier Fly (BSF) maggots, are rich in protein and fat, making them an excellent alternative feed for fish. Utilizing them as a fish feed source and as a bio-machine for waste processing requires cultivating maggots. This study was conducted for 30 days, from February 6 to March 6, 2024, at the Fish Seed Center (BBI) of the Faculty of Agriculture, Riau Islamic University, Pekanbaru. The method used was a completely randomized design (CRD) with 5 treatments and 3 replicates, namely, P1 = palm kernel meal thickness (5 cm), P2 = 7 cm, P3 = 9 cm, P4 = 11 cm, and P5 = 13 cm. The study's results showed the best results in treatment P5, with a weight gain of 0.252 g, a length gain of 1.83 cm, a daily growth rate of 0.00351%, and an average production of 967 g. The best culture medium content test results were obtained from P5, with water content of 29.74%, protein of 36.60%, fat of 4.31%, carbohydrates of 1.31%, and crude fiber of 2.13%. The environmental parameters during the study were a temperature range of 35.7 to 41.2 °C, a humidity range of 70-96%, and a pH range of 6.3-6.5. ]]>
