As an organic waste reducer, Black soldier fly (BSF) larvae are an alternative in overcoming organic waste problems. Environmental conditions, larval density, amount of waste, time of waste application, and type of waste are reasons why the existing organic waste treatment with BSF larvae still needs to be improved. The main objective of this research is to develop the potential of black soldier fly larvae in reducing various types of organic waste (vegetable, fruit, restaurant waste, and mixed waste). To achieve the main objective of this study, the steps taken were analyzing the environmental conditions at the research site, the density of larvae in the reactor, the amount of organic waste, and the time of waste feeding on larval survival and the effectiveness of organic waste reduction. To implement the stage, sample preparation, selection of waste samples, making reactors, starting waste treatment, and measuring the results were carried out. It was found that BSF larvae at temperatures up to 34 °C, pH 8 with a larval density of 200 larvae, feeding 100–200 mg/larvae/day for 21 days were able to reduce organic waste by 84.5% with a waste reduction index value of 4.02%, a digested feed conversion efficiency value of 16.15% and a larval survival rate of 100%. Environmental conditions, larval density, amount of waste, time of waste feeding, and type of waste fed succeeded in reducing organic waste quickly compared to other organic waste treatments.
