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.

Abstract

The need for clean water is one of the essential aspects of community life, especially in areas that are not fully served by the PDAM (Regional Drinking Water Company) distribution network. In Sumber Rejo Subdistrict, particularly in RT 7, the availability of clean water remains a major issue due to the hilly topography, making it difficult for the PDAM pipeline network to reach the area. The local community relies on springs as an alternative water source, which is collected manually without a planned distribution system. This study aims to analyze the potential of the spring in RT 7, Sumber Rejo Subdistrict, as a clean water source based on water quality, flow rate classification, and clean water distribution system planning. The methods used include water quality analysis through laboratory tests covering physical, chemical, and microbiological parameters, flow rate classification based on spring discharge measurements, and distribution system planning using EPANET 2.2 software. The results show that the spring water quality does not fully meet the clean water quality standards according to the Indonesian Ministry of Health Regulation Number 2 of 2023 on Environmental Health, particularly for nitrate, manganese, and aluminum parameters. Based on the flow rate measurements, the spring falls into Class VI, with a flow rate ranging from 0.1 to 1 liter per second, indicating low flow capacity and generally only sufficient to meet water needs on a limited scale (less than 1,000 people). In the clean water distribution network simulation, three alternative distribution scenarios were evaluated, with Alternative 2 showing the most optimal results, with flow velocities ranging from 0.31 to 0.46 m/s

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.
