Abstract

Tofu wastewater contains high levels of organic pollutants, which has the potential to pollute the environment, which has an impact on decreasing water quality, triggering unpleasant odors, and potentially causing health problems. Coagulation-flocculation is a common method to reduce pollution because it is effective in reducing COD and TSS. However, synthetic coagulants have a negative impact on the environment, produce excess sludge, and require high costs. Tamarind seeds and avocado seeds contain protein and tannins that act as natural polyelectrolytes to reduce organic matter and suspended solids. This study aims to identify the COD, TSS, and pH content of tofu wastewater and analyze the effectiveness of the combination of the two seeds as biocoagulants using the jar test method with dose variations. There are 8 variations in biocoagulant doses, each as much as 4 g/L with different dose ratios, namely control, 100:0, 0:100, 70:30, 60:40, 50:50, 40:60, and 30:70. The results showed that the combination of the two biocoagulants was able to significantly reduce COD and TSS concentrations with the highest reduction effectiveness of 69% and 88%, respectively. The best dose for reducing COD was dose C, while for TSS was dose E. Thus, tamarind seeds and avocado seeds have the potential as an alternative environmentally friendly coagulant in industrial wastewater treatment.

Abstract

The tofu industry in Karawang Regency produces liquid waste with high BOD, COD, and TSS content that can pollute the environment. The study aims to test the effectiveness of moringa seeds (Moringa oleifera) as a natural coagulant in reducing these pollutant parameters and to assess its economic feasibility. The method used involved laboratory testing with coagulation-flocculation processes using varying doses of moringa seed powder (11g, 13g, 15g, and 17g), followed by analysis of BOD, COD, and TSS. Financial viability was analyzed using the NPV, IRR, and Net B/C Ratio indicators. The results showed that a dose of 13 grams reduced COD by 57.51% and BOD by 34.63%, while TSS decreased by 59.06% at a dose of 11 grams. Financial analysis indicates that the use of moringa seeds as a coagulant is feasible with an NPV of Rp5,754,422, an IRR of 13.75%, and a Net B/C Ratio of 1.09. Thus, moringa seeds have proven to be effective and economical as a natural coagulant in soybean curd wastewater treatment and can serve as an environmentally friendly alternative for small-scale industries.

Abstract

The peel of Kepok banana (Musa paradisiaca L.) can be utilized as an environmentally friendly coagulant in the treatment of tofu industry wastewater. This study examined the effectiveness of the bio-coagulant derived from Kepok banana peel in comparison to the chemical coagulant Poly Aluminium Chloride (PAC) in reducing pollutant concentrations in the tofu industry "X". The coagulation-flocculation process was conducted at laboratory scale with varying coagulant doses of 0.4 g/L, 1.2 g/L, 2 g/L, and a control test. The mixing process involved rapid stirring at 200 rpm for 5 minutes, followed by slow stirring at 40 rpm for 10 minutes, and settling for an hour. The wastewater pH was optimized to 8. The results showed that a 0.4 g/L dose of Kepok banana peel reduced BOD levels by 29.8%, COD by 58%, and TSS by 41%. For comparison, a 0.4 g/L dose of PAC demonstrated higher effectiveness, reducing BOD by 26.8%, COD by 56%, and TSS by 28%.

Abstract

Domestic wastewater discharge remains a major factor contributing to the deterioration of river water quality, as untreated effluents are still commonly released directly into river systems. This concern is particularly evident in the downstream segment of the Kusan River tributary, situated in the villages of Sungai Lembu and Beringin. The intensifying expansion of residential settlements in the area has been identified as a key driver of pollution in the Kusan River, with its scale increasing annually. Environmental degradation arises when the pollutant load exceeds the assimilative capacity of the aquatic ecosystem. Under such conditions, the natural recovery process becomes protracted and increasingly ineffective, resulting in persistent contamination. This research is designed to assess the influence of surrounding anthropogenic activities on the water pollution index and the ecological condition of the Kusan River tributary in the aforementioned villages, within Tanah Bumbu Regency, South Kalimantan Province, employing the Water Pollution Index (WPI) methodology. Based on laboratory analyses, Total Suspended Solids (TSS) concentrations in the lower reaches of the tributary exceed 50 mg/L, thus surpassing the threshold set by Government Regulation No. 22 of 2021 concerning Water Quality Management and Pollution Control. Moreover, findings from the pollution index evaluation indicate that water quality in the study area ranges from good to lightly polluted, with index scores varying between 0.33 and 1.73.

Abstract

The growth of industry in Karawang Regency impacts the increase in burning activities in the production process, which has the potential to become a source of air pollution. These activities generate pollutants that are hazardous to humans and ecosystems. This research aims to analyze the meteorological factors influencing the distribution patterns of TSP pollutant concentrations, as well as to map the distribution patterns resulting from burning activities in the chemical industry using AERMOD View, during the dry and rainy seasons, which will produce the concentration values of pollutants received by receptors. The method used is quantitative, using an air pollutant dispersion modeling approach using AERMOD View. Secondary data consists of emission data, meteorological data, and topographic data. Data analysis was performed by comparing the AERMOD View modeling results across seasons. Furthermore, concentration values were compared with Ambient Air Quality Standards referred to in Government Regulation No. 22 of 2021. Based on the research, the combination of meteorological factors, wind direction, and wind speed are the main parameters. The pattern of pollutant dispersion is determined by the interaction between wind direction, distance, receptor elevation, when combined with the physical characteristics of the chimney and the amount of emission load released by the emission source, it will determine the magnitude of the pollutant concentration received by the receptor.
