Utilization of Grase Trap Waste as a Maggot Black Soldier Fly Growth Media

Grase traps are typically installed in the kitchen outlets of restaurants, the food industry and hospitals aimed at capturing oil and grease before waste enters the main wastewater treatment channels. Given the great potential of the fat produced, the researcher is interested in conducting research on the utilization of waste grase trap as a growth medium for Black Soldier Fly maggot. One of the innovations in managing organic waste is through bioconversion using Maggot Black Soldier Fly. This research aims to find out the effectiveness of waste grase trap as a growth medium for maggot black soldier fly. This type of research is a pseudo-experiment with a pre and post-test design. 2000 grams of organic waste was used for each medium with 120 grams of 7-day-old maggot. To see the difference in the most effective media, an independent T-test was used. The results showed that the increase in the weight of Maggot Black Soldier Fly was highest in the fat medium, at 705.175 grams. There was a significant difference (p-value 0.033) between the treatment of fat media and leftover rice. It can be concluded that the fat medium is more effective in increasing the growth of Maggot Black Soldier Fly than the leftover rice. However, in its application, it is necessary to spray EM4 on the feed medium to reduce the odor due to the process of fat decomposition by maggot
