Chili peppers (Capsicum sp.) is one type of commodities that has a high economic value. Excessive use of chemical fertilizers are causing environmental pollution and generating residues. One effort that can be done is to use the liquid organic fertilizer leachate results of bioconversion Black Soldier Fly (BSF) larvae. Research on leachate utilization has been carried out as a liquid organic fertilizer on chili plants with the Urban Rooftop Farming (URF) system. Chili plants after moving planting were sprayed using Leachate 1%, Leachate 2%, and Leachate 3%, as well as compared to control (without nutrients) and NASA® every two times in a week. Observations were made on the height of chili plants, number of chili branches, wet weight, dry weight, fruit dimension, and vitamin C content. Macro and micro nutrient content of leachate as liquid organic fertilizer was analyzed in BALITSA. The results of this research showed that the leachate of BSF has macro and micro nutrient elements required by chili plants, although the content of N, P and K are still slightly lower than NASA®. Leachate treatment of 1% showed the results that the number of branches 15.95 ± 5.21 pieces, plant height 23.41 ± 8.22 cm, wet weight 1324.43 grams, dry weight 604.24 grams, fruit length 5.64 cm, fruit width 0.72 cm, and vitamin C content of 56 mg/100 gram and statistically not significantly different from other treatments. The highest weighting values of wet chili and chili vitamin C content were obtained from the Leachate treatment of 1%. From the results of this study, Leachate treatment of 1% can be said to be equivalent to NASA® to be applied as a liquid organic fertilizer on the chili plant, Capsicum sp.
