Abstract

Organic waste includes fruits, vegetables and coconut dregs which still contain nutrients in them. The nutritional content of fruit, vegetable and coconut waste can be used as an alternative feed for the mealworm (Tenebrio molitor L.). The nutritional content is not sufficient for the mealworm (Tenebrio molitor L.) so that a fermentation treatment using EM4 is needed to increase the nutrient content in the organic waste media. This study aims to determine the Organic Waste Reduction Index (WRI), growth, namely length and weight and life expectancy of mealworm (Tenebrio molitor L.). The research was carried out from November 2022 to February 2023. Organic waste in the form of vegetables, fruit and coconut dregs was obtained from the Timbangan market, Indralaya, South Sumatra. The larvae of Tenebrio molitor L. come from the cultivator community in Lahat, South Sumatra. Maintenance of test animals, calculating the organic waste reduction index, measuring growth, and survival of mealworm (Tenebrio molitor L.) was carried out at the Biosystematics Laboratory, Department of Biology, FMIPA, Sriwijaya University. The study design used a completely randomized design with 6 treatments and each treatment was repeated 5 times. The variables measured in this study were the Organic Waste Reduction Index, Growth and Survival of the larvae. The results of this study showed that the best organic waste composition for the Reduction Index (WRI) parameter was treatment 3. The composition of mixed media was 15 g of fermented fruit vegetable waste + 5 g of fermented coconut dregs with an average of 4.18% and the lowest value was found in the treatment 2 with an average of 1.15%. In growth with an average length of 6.03 mm (range 1.05-6.03 mm) and an average weight range of 0.028 g (0.004-0.028 g). The best treatment composition for survival parameters in the control treatment and a mixture of fermented vegetables, fruit 10 g + 10 g coconut pulp with a value of 100% survival of mealworm. The conclusion of this study is that the composition of fermented vegetables, fruits and coconut dregs has a significant effect on the Organic Waste Reduction Index, the growth and survival of the mealworm (Tenebrio molitor L.).
