Abstract
Aims: The study aims to determine the effectiveness of Black Soldier Fly (Hermetia illucens) larvae in processing vegetable waste into compost with the addition of molasses and EM4.
Methods: This study was conducted from March to August 2022 at the Environmental Engineering Laboratory, Faculty of Civil Engineering and Planning, Universitas Islam Indonesia, Yogyakarta. The composting process was evaluated by analyzing its physical properties (pH, moisture content, temperature, color, and odor) and chemical properties (phosphorus, carbon, nitrogen, and C/N ratio).
Result: Feed consumption, waste reduction index (WRI), and reactor performance show that the reactor containing vegetable waste fermented with EM4 was the most effective. The amount of vegetable waste supplied was 350–400 g every seven days. In the EM4 reactor, the parameters obtained over three consecutive weeks were as follows: feed consumption of 94%, 99%, and 97%, and WRI values of 0.9, 0.14, and 0.43, respectively. The analysis of waste reduction during the composting of vegetable waste with the addition of molasses and EM4 using Black Soldier Fly (Hermetia illucens) larvae demonstrated high efficiency. However, the compost produced did not fully meet the quality requirements specified in SNI 19-7030-2004.
