Organic waste can be minimized by using a bioconversion agent, namely Black Soldier Fly maggot. BSF maggots need good food so that they can speed up their life processes and the process of digesting food. The aim of this research was to determine the best feed composition with the addition of purple sweet potato flour, coconut dregs and pineapple peel on consumption rate, conversion efficiency …
BSF maggots are organisms that can decompose waste quickly. The life cycle of black soldier flies is maggots (larvae), prepupae, pupae and adult insects. Sweet potato flour as a prebiotic contains fructo-oligosaccharides (FOS) and Raffinose which can increase immunity, kill pathogenic bacteria, and balance microorganisms in the digestive tract of BSF maggots. This study used a Completely Random…
Free radicals are the result of the respiration process. Free radicals are very dangerous for the body because they can cause various diseases such as premature aging, cancer, atherosclerosis, lung disorders, kidney diseases, cataracts, rheumatism and diabetes mellitus. Antioxidants are involved in protecting the human body from damage caused by free radicals. Mempelas plants contain antioxidan…
Epilachna admirabilis pests are a threat to horticultural crops, while chemical insecticides can cause resistance, environmental pollution, and health risks.
