Abstract

Margasari Village has different regional characteristics, the difference in the characteristics of the area causes differences in the waste management system in Margasari Village between land and water areas, resulting in differences in waste management methods and techniques. This study aims to determine the factors that influence the problem of solid waste management systems in land and water areas that cause it is not achieved optimally, using the Analytical Hierarchy Process (AHP) method. After the data processing and analysis were carried out, the factors that influenced the solid waste management system problems in Margasari Village were based on the components of the solid waste management system, namely operational techniques, institutions, financing, law and regulation, community roles and physical conditions, so that the results of the waste management system priority factors in Margasari Village, namely in the mainland area, the Community Role Indicator has a weight value of 0.29, and the priority weight of the Waste The processing variable has a weight value of 0.100 which is a variable that affects the problem of Community Roles in the Solid Waste Management System in Land Areas. Meanwhile, in the area over water, the Community Role Indicator has a weight value of 0.31 with a priority weight of the influencing variable Waste Processing with a weight value of 0.093.

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.
