Abstract

Waste generation in Tasikmalaya City reached 323,156 kg/day. Waste bank is a programme as an effort that can be done to reduce waste generation. Tasikmalaya has 74 waste bank units, 4 of which are in Indihiang district. According to the Environmental Department, the waste generation in Indihiang District is 25,664 kg/day. It's not yet known for sure how much waste reduction potential this programme has. Therefore, structural equation modelling (SEM) is used to analyse it. SEM is a method for processing data from questionnaires to determine the influence of the community's role in reducing waste through waste banks. The data results from the SEM method are processed using SmartPLS. The results show that the waste reduction potential through waste banks in Indihiang is currently 0.15%, but it can still be increased to 15% by increasing the number of waste bank customers. According to the SEM-PLS result, there is a significant influence between people's knowledge and behaviour on waste reduction, but in the aspect of people's attitude, the attitude of non-customers does not have a significant influence on waste reduction.

Abstract

Phosphate and Ammonia rich fertilizer wastes pose potential environmental problems. Depletion of natural phosphate sources encourages the search for sustainable alternatives. This study examined phosphate recovery from fertilizer plant effluent using struvite (MgNH4PO4-6H2O) in a batch vertical reactor. The factors studied were pH, temperature, air flow rate, and solution molar ratio. Struvite is formed by reacting Mg2+, NH4+, and PO43-ions. This study used MgCl2 : waste molar ratios of 2:1, 2.5:1, and 3:1, air flow rates of 0.25, 0.50, 0.75, and 1.00 L/min, and pH of 8, 9, 10, and 11. The MAP solution with the specified molar ratio was introduced into the reactor up to 3⁄4 of its volume. The air flow rate and pH were set according to the parameters. The MAP solution was collected and filtered to produce struvite. Struvite crystals were analyzed by XRF and SEM. Results showed the best phosphate recovery of 67.3% at a ratio of 2.5:1, air flow rate of 1.00 L/min, and pH of 10. This study demonstrates the potential of struvite as a sustainable phosphate recovery solution from fertilizer waste

Abstract

One industrial sector that has experienced significant development in Indonesia is the animal feed industry. This industry produces various types of waste, including leftover raw materials, products that do not meet specifications, and used packaging. Management of non-B3 waste (Hazardous and Toxic Materials) is very important to avoid negative impacts on the environment. To design a waste management system in an area, initial data is needed which includes the amount of waste produced, the composition of the waste, and the characteristics of the waste in the area where the management system will be planned. This research analyzes the condition of non -B3 solid waste management in the animal feed industry, with a focus on waste generation and composition. Sampling was carried out for 8 days in accordance with SNI 19-3964-1995. The research results showed that domestic waste reached 14,093 kg/day and industrial waste reached 1641.53 kg/day. In the office area, waste is dominated by food scraps (29.11%) and tissue paper (16.45%), while in the yard area, cigarette butts (30.38%) and food scraps (19.38%) are dominant. Most industrial waste comes from corn tubies (62.46%) and carbonate sacks (22.43%). These findings are important for designing effective solid waste management systems in the animal feed industry, maintaining environmental sustainability, and meeting regulatory standards
