Abstract

Wastewater produced from chicken slaughterhouse (RPA) industrial activities is liquid waste containing organic compounds in high concentrations that have the potential to damage the environment if not treated first before being discharged into water bodies. This study aims to determine the effectiveness of moringa seed biocoagulant performance in removing BOD, COD, and TSS parameters. The dosage variations of moringa seed biocoagulant used in this study were 20 mg/L, 30 mg/L, 40 mg/L, 50 mg/L, 60 mg/L, and 70 mg/L with a coagulation speed of 120 rpm for 2 minutes, a flocculation speed of 20 rpm for 20 minutes, and a settling time of 2 hours. The results of the study showed that the optimum dose of moringa seed coagulant which had the lowest turbidity level was at a dose of 50 mg/L, where the optimum dose of coagulant could be effectively used in the removal of BOD, COD, and TSS pollutant parameters at a dose of 50 mg/L with a BOD removal of 49.8% from the initial characteristics of 1,683.5 mg/L to 845.12 mg/L, COD removal of 27.2% from the initial characteristics of 4,060.8 mg/L to 2,955.36 mg/L, and TSS removal of 30.4% from the initial characteristics of 427 mg/L to 297 mg/L. The RPA wastewater effluent that had been treated using moringa seed biocoagulant could remove BOD, COD, and TSS pollutant parameters in chicken slaughterhouse wastewater, but still did not meet the Quality Standards of the Minister of Environment Regulation No. 5 of 2014.

Abstract

Industrial waste that contains heavy metal can cause environmental problem because of its toxicity, persistency and accumulation level in the environment. Biosorption process is highly influenced by temperature, pH, light, contact time, and ratio of surface area. Microalgae which possess two functional groups that are able to react on metal ion in a solution can be exploited to overcome environmental pollution due to heavy metal compound. Closed cultivation system in a photobioreactor is utilized to overcome contamination and evaporation problems on open pond system. Heavy metal analysis is conducted by utilizing Atomic Absorption Spectroscopy (AAS), Fourier Transform Infra-Red (FTIR), and Scanning Electron Microscope (SEM). This article provides information on biosorption as alternative technology to overcome heavy metal in water areas with no side effects on the environment with advantages of the absence of secondary pollutants, high level of efficiency, and relatively economic compared to physic-chemical method heavy metal removal methods

Abstract

The rapid urban development of South Tangerang City, established under Law No. 51/2008, has led to significant challenges in municipal solid waste management. With a population density of 8,632 people/km² and daily waste generation reaching 972.628 tons, the city's existing landfill, Landfill Cipeucang, has experienced operational issues including a major waste slide in 2020 and ongoing community complaints about odors. These issues are exacerbated by the landfill's proximity to the Cisadane River, a critical source of drinking water, necessitating immediate action to ensure environmental and public health safety. Aim: This study aims to identify suitable alternative landfill locations to support the relocation of Landfill Cipeucang using spatial and technical criteria. Methodology and results: The method employs a spatial analysis approach through Geographic Information Systems (GIS), utilizing layering and buffering techniques based on parameters such as distance from settlements, water bodies, airports, disaster risk zones, and hydrogeological characteristics. Overlay analysis was performed to pinpoint optimal sites. The results indicated several candidate locations that meet all environmental and technical standards. Comparative evaluation among alternatives revealed the most appropriate site, considering accessibility, minimal disaster risk, and land suitability. These findings are consistent with recent landfill management research in Indonesia advocating for site relocation and innovation in waste handling. Conclusion, significance, and impact study: In conclusion, relocating the landfill based on systematic spatial and technical analysis is critical to achieving sustainable waste management in South Tangerang City and preventing further environmental degradation.
