The tofu industry in Cipondoh Subdistrict, Tangerang City, is growing rapidly, but the liquid waste produced is a serious environmental issue. This study aims to analyze the treatment of wastewater from the tofu home industry, focusing on the levels of BOD, COD, TSS, and pH of the waste, as well as the level of knowledge and attitude of employees regarding waste management. The method used was descriptive quantitative, with wastewater sampling in the morning using a composite sampling technique from two locations, namely raw water and wastewater discharge. Analysis was conducted at the Tangerang Regional Health Laboratory for the specified parameters. The results showed that many tofu industries have not implemented waste treatment properly, causing environmental pollution. In addition, the assessment of employees' knowledge level ranged from 'less' to 'sufficient', with attitudes needing to be improved for more effective waste management. The findings are expected to be a reference for the improvement of liquid waste management in the tofu industry that is more environmentally friendly.

2024-12-14T13:50:44+08:00

The quality of clean water used for daily needs must meet health requirements and be safe to use, well water often contains various dangerous metals, one of which is iron. Processing of the clean water system at Rt 05 Citeureup Village, North Cimahi District is not yet available, because it made The residential area is a rice field area, where this condition can be the cause of Fe contamination in dug wells. The aim of this research is to determine the effect of variations in the contact time of silica sand and active sand in a simple filtration device on reducing Fe levels in clean water. The research method used is a quasi-experimental method. The sample in this study was tap water from one of the residents' houses which was contaminated with excess Fe. The sample size used in the research was based on three treatments, namely variations in contact time for silica sand and active sand filter media. The research was carried out by collecting data directly by examining Fe after treatment and then comparing the reduction results. In this study, the iron (Fe) content obtained before treatment was 1.65 mg/l and after treatment was 0.12 mg/l, the highest decrease was in the 3rd treatment for 15 minutes with a percentage of 92. 51% and there is a significant difference in the use of different contact times for active sand and silica sand filter media with contact times of 5 minutes, 10 minutes, 15 minutes in reducing iron (Fe) levels in clean water in RT 05 Citeureup Village, North Cimahi District
