ANALYSIS OF THE EFFECT OF VARIATIONS IN ORGANIC WASTE COMPOSITION ON BODY WEIGHT GROWTH OF BLACK SOLDIER FLY LARVAE (HERMETIA ILLUCENS)

The increasing amount of organic waste requires special attention in its management. Efforts to conserve and
manage organic waste in bioenergy are one of the current intensive efforts through the cultivation of BSF
maggots. This study aims to see the effect of variations in waste composition on body weight growth in maggot
growth, analyze fat, protein, and water content based on variations in waste composition decomposed by
maggot, and determine the Waste Reduction Index (WRI). This research is a quasi-experiment with the preand-post Group Design method, using 5 variations of a waste composition consisting of catering waste,
vegetable and fruit waste with washing or chopping treatment. The growth of magot larvae body weight was
best in the variation of catering waste with slurry treatment, with the final weight of magot reaching 3025 grams
from the initial weight of larvae weighing 50 grams. Proximate analysis was carried out on a maggot that was
21 days old, namely water content ranging from 60.73% to 65.42%, and fat content from 47.29% - 51.24%.
The protein content is 19.11% - 42.76%. The results of one-way Anova analysis obtained Sig value. (0.000) <
α then H0 is rejected, it can be concluded that the five variations of waste composition in maggot feed have a
different average weight gain of maggot, and have different weight gain. The WRI value obtained is 2.4 - 2.99
