Abstract

Food waste is a significant environmental issue, leading to resource wastage and greenhouse gas emissions. This study examines the treatment of food waste through anaerobic fermentation (AF) and composting, aiming to recover value from waste and reduce negative environmental impacts. In this research, food waste, fruit peels waste, dry leaves, rotten kale and mustard greens, and other organic materials were composted using an anaerobic composter, with observations covering pH, temperature, moisture content, and nutrient levels such as nitrogen, phosphorus, and heavy metals. The results show that the compost pH ranged between 7.2 and 7.4, meeting the standards of SNI 19-7030-2004. Total nitrogen content reached 1.78-3.10%, while phosphorus ranged from 0.5-1.2%. Heavy metal concentrations, including lead (Pb) and cadmium (Cd), were below the safe limits for organic fertilizers. In conclusion, AF and composting techniques effectively convert food waste into high-quality organic fertilizer that meets national standards, with the potential to reduce environmental pollution.

Abstract

The increasing number of laundry businesses has led to higher detergent usage, containing pollutants such as Sodium Dodecyl Benzene Sulfonate (NaDBS) and Sodium Tripolyphosphate (STPP), which are difficult to decompose naturally and can contaminate aquatic environments. This study aims to analyze the effectiveness of phytoremediation using water hyacinth (Eichhornia crassipes) in reducing pollutant concentrations in laundry wastewater, focusing on COD, TSS, and phosphate parameters. The research utilized purposive sampling to collect laundry wastewater samples from a large-scale laundry outlet in Sumbang, Bojonegoro, and water hyacinth samples from a fish pond in Sukorejo, Bojonegoro. Wastewater treatment was conducted in treatment tanks for 14 days, with initial (day 0) and final (day 14) sample testing performed at the PPSDM Migas Cepu Laboratory. This research was conducted in an experimental and quantitative way to calculate its effectiveness. The results showed a visible transformation in laundry wastewater from turbid gray water to a clearer state after 14 days of treatment. Physical changes were also observed in the water hyacinth, including leaf discoloration to yellowish-brown and stem decomposition. Laboratory analysis confirmed that phytoremediation using water hyacinth effectively reduced pollutant concentrations, achieving COD reduction of 74–76%, TSS reduction of 90–95%, and phosphate reduction of 75–91%. Among these parameters, TSS removal showed the highest efficiency. These findings indicate that water hyacinth can serve as an eco-friendly alternative for laundry wastewater treatment.

Abstract

Landslides are the most common type of disaster in Bogor City compared to other disasters. The large number of built-up areas that are not following the Bogor City Spatial Plan (RTRW) has the potential to cause disasters that can result in material losses and fatalities. The objectives of the study: 1) Identifying the level of landslide susceptibility in Bogor City, 2) Identifying the level of landslide susceptibility in built-up areas in Bogor City. This study used the Geographic Information System (GIS) method using 5 landslide susceptibility parameters, namely: rainfall, rock type, soil type, slope, and land use. The results of this study indicate that from the area of Bogor City of 11,130.31 ha, areas with low level of  landslide susceptibility are 50,20%, areas with moderate level of landslide susceptibility are 46,36%) and areas with high level of landslide susceptibility are 383.54 ha (3,45%). The built-up area in Bogor City is 6,274.34 ha, low landslide susceptibility is 60,69%, medium landslide susceptibility is 54,35% and high level of  landslide susceptibility is 20,65%. There are built-up areas that are in line with the Bogor City Spatial Plan 2011-2031 with a moderate landslide susceptibility level of 45.44% and a high landslide susceptibility level of 16.87%. Based on these findings, the Bogor City Government can proactively reduce disaster risks in areas with medium and high landslide susceptibility. To mitigate it, stricter spatial planning controls and Building and Environmental Planning  are needed for settlements located in areas with high landslide susceptibility.

Abstract

Water is a very basic need for human life on earth. At this time, water is a problem that needs careful attention. Drinking water is water that is consumed directly by humans through a processing process or processing stages that meet health requirements. The busier human activities are, the more people tend to choose a more practical way with relatively low costs in meeting drinking water needs. The fulfillment of drinking water needs is highly dependent on the coverage of drinking water services and sanitation conditions in the community. This study aims to determine the level of contamination of Escherichia coli and coliform bacteria in refill drinking water and the feasibility of refill drinking water depots in Trucuk District, Bojonegoro Regency. The method used in this study is descriptive with a quantitative approach. The results of the study from 4 samples, namely AB, DAM 1, DAM 2, and DAM 3. 3 samples including AB, DAM 1, and DAM 3 were positive for containing Escherichia coli and coliform bacteria. Refill drinking water samples and raw water do not meet the requirements in accordance with the quality standards in the Regulation of the Minister of Health of the Republic of Indonesia No. 492 of 2010 "Concerning Drinking Water Quality Requirements" where the standard for microbiological parameter quality is 0 CFU / 100 ml.

Abstract

Bandung Regency in 2023 built a TPST (Integrated Waste Management Site) with a capacity of 75 tons/day with the mechanical method "One Day Process" and a capacity of 20 tons/day with the biological method "Biodrying". The fact is that the capacity was not realized according to plan. This study is to evaluate the differences between the Biodrying and One Day One Process methods in producing RDF (Refuse Derived Fuel) and to compile a dynamic model of waste management through sustainable RDF. This study was conducted using a dynamic system using Powersim software with simulations from 2023 to 2024. Existing management was modeled and analyzed with a dynamic system. The results of the study showed that the biodrying method was superior to the capacity and quality of RDF products and had operational cost savings for electricity needs. The modeling results showed that the performance of waste management from 2023 to 2034 was only 10.35 tons/day for the one day one process method and 9.8 tons/day for the biodrying method, as a result, unmanaged waste increased every year. To maximize capacity, the Bandung Regency regional government needs to intervene with policy steps that support the sustainability of TPST.

Abstract

The increasing number of laundry businesses leads to an increasing amount of wastewater produced. The resulting laundry waste contains phosphates that if disposed of without treatment can provide eutrophication in the body of water. This study aims to lower phosphate levels found in laundry wastewater in the Dipatihukur area, Bandung using a constructed wetland system using the Equisetum hymale plant. Lowering phosphate levels using Equisetum hymale plants with variations of stay time of 1, 2, 3, 4, and 5 days with batch system. The results obtained showed that phosphate levels in waste before treatment of 10,846 mg/L. The value is greater than the standard of quality set by the government of 0.2 mg/L. Test Processing with Constructed Wetland shows that the plant Equisetum hymale can set aside phosphate significantly. The lowest phosphate rate after processing reached 0.227 mg/L with 96.75% contact time for 5 days. Phosphate preliminary rate by plants can be reduced with time of contact with the plant. The mechanism is the process of adsorption by the plant Equisetum hymale by referring to the first-order kinetic model by showing the value of regression coefficient (R2) 0.9014.
