Abstract

Efforts to reduce organic waste can be done by recycling waste through utilization into liquid organic fertilizer. One of the efforts to process organic waste can be done by Black Soldier Fly (BSF) maggot. This study was conducted with the aim of seeing the ability of liquid organic fertilizer (POC) produced from leachate from bioconversion carried out by BSF, on the growth of miana plants (Plectranthus scutellarioides). This research is an experiment with qualitative and quantitative data analysis methods. The research was conducted by giving two different POCs. Sample A used 100% commercial organic fertilizer and sample D used POC with a ratio of bioconverted organic fertilizer to commercial liquid fertilizer (3:1). Both samples still could not meet the quality standards of nutrients (NPK) and C-organic. However, the sample with the ratio of bioconverted organic fertilizer and commercial liquid organic fertilizer (3:1) or sample D is the optimum sample, with nutrients (NPK) reaching 0.438% and C-organic reaching 4.58%. The results of the application proved that plants with sample D showed the best growth in terms of the number of leaves that reached 14 strands and plant height reached 13 cm in week 8.

Abstract

The problem of organic waste management in Balikpapan City is increasing, with a total of 193,038 tons/year, 70.3% of which comes from household waste. One solution implemented at Manggar Municipal Solid Waste (MSW) Landfill in Balikpapan is the processing of organic waste using maggots (BSF larvae). This study aims to analyze the current conditions, analyze the factors influencing waste processing, and formulate strategies for optimizing the processing facility. The methods used include quantitative and qualitative approaches, as well as best practice analysis as a basis for improvement. The research findings highlight several issues, such as the absence of BSF egg weighing, predator disturbances in the fly cages, biopon systems without drainage channels, and the manual process of separating maggots from casings. Optimization was carried out through the redesign of the BSF fly enclosure, improvement, and addition of 21 biopon units, which can produce 35.7 liters of liquid organic fertilizer (POC) and decompose 1,0878 tons of organic waste per cycle, the design of a sieving machine, and the reorganization of the maggot house layout. These efforts are expected to enhance processing efficiency and capacity to 1,0878 tons per cycle, supporting more sustainable and environmentally friendly waste management.
