Analysis of Maggot Nutrition in Various Farming Periods and Organic Wastes as a Growth Medium

Abstract

Undoubtedly, the bioconversion of organic waste into maggots is an innovation to reduce organic waste generation. Nonetheless, maggot cultivators only use available organic waste as feed, without adjustments, which makes the nutritional value of maggot produced inconsistent. The current study aims to determine appropriate organic waste and farming periods based on the nutritional value of maggots. This research was conducted using a field-scale experimental method for 21 days. A total of 9 experimental variations of organic waste type and farming period were observed, i.e., kitchen waste, rotten vegetables, and a mixture of both (50:50, w/w) for 7, 14, and 21 days of farming, respectively. The results showed that the appropriate organic waste for maggot farming is kitchen waste, with a farming period of 14 days. During the 14-day farming process, maggot weight increased 1,750 times to 3,500 grams, with protein and fat content of 38.28% and 28.47%, respectively. The protein content in maggot meets the minimum requirements for fish and poultry use as an alternative feed.
