Bioconversion of Edamame Soybean Waste Using Black Soldier Fly Larvae on Substrate Consumption and Waste Reduction Index

This study aimed to measure substrate consumption and waste reduction index of edamame soybean using Black Soldier Fly (BSF) larvae as a bioconversion agent. This study used a Completely Randomized Design (CRD) with three treatments: unfermented edamame soybean waste (F0), fermented for 7 days (F7), and fermented for 14 days (F14). The observed bioconversions included substrate consumption and waste reduction index (WRI). Data analysis used analysis of variance with a confidence level of 5%. The results showed that waste fermentation significantly affected substrate consumption and waste reduction index. The highest average substrate consumption was obtained in treatment F14 (57.96±7.37), followed by F7 (41.61±6.73) and F0 (28.51±4.97). Likewise, with the waste reduction index, the F14 treatment showed the highest reduction (2.37±0.61), followed by F7 (3.46±0.56) and F0 (4.83±0.41). This shows that the longer the fermentation, the higher the substrate consumption and the effectiveness of waste reduction by BSF larvae.
