“…Organic waste will be oxidized by potassium bichromate (K2Cr2O7) as an oxygen source to become CO 2 and H 2 O gas, as well as several chromium ions. The COD value is a measure of the level of pollution by organic materials [10]. COD is needed to decompose all organic materials in water because the existing organic materials are deliberately decomposed chemically using the strong oxidizer potassium bichromate in acidic and hot conditions with a silver catalyst.…”

This research aims to determine the level of reduction in BOD and COD in household wastewater after the filtration process and to determine the efficiency of the filter media in reducing BOD and COD in sewage. The research was conducted in Bilebante village, Central Lombok Regency, NTB. The method takes three wastewater samples at different locations before and after the filtration stage. The results of the research show that the COD concentration in domestic wastewater before going through the processing process using filtration media obtained a result of 63 mgl/L, then at the filtration stage using plastic bottle media, the result was 34 mgl/L with an efficiency value of 46%, and at the filtration stage using activated carbon media, a value of 12 mgl/L was obtained so that the resulting efficiency value was 64%. The results of the BOD concentration in domestic wastewater before going through the processing process using filtration media obtained an initial result of 1.6 mgl/L; then, at the filtration stage using plastic bottle media, the result was 0.6 mgl/L with an efficiency value of 62 %. At the filtration stage using active carbon media, a value of 0 mgl/L was obtained, with an efficiency value of 100%. This research concludes that wastewater is safe to use, whether for watering plants or other things because there is a decrease in levels of COD and BOD that meet quality standards.

“…COD analysis is an analysis that aims to determine the amount of organic material contained in liquid waste. Chemical Oxygen Demand is the amount of oxygen needed for a material in water so that it can be oxidized through chemical reactions and organic waste materials will be oxidized by potassium dichromate which is used as an oxygen source [12]. The results of the analysis of COD levels in soymilk wastewater can be seen in Figure 1.…”

Processing of soymilk liquid waste is carried out using the batch system electrocoagulation method. Variations in processing time are 20, 40, 60, 80, 100, and 120 minutes. The plate used is an aluminum plate measuring 10×5 cm. The electrode distance was 2 cm with an electrical voltage of 10 and 30 volts. The results of this research show that the best electrocoagulation process can reduce COD levels by 64.70%, TSS by 72.90% and increase the pH value to 5.17, however COD, TSS and pH levels are still above standard quality. Initial analysis results of soymilk wastewater with pH 4.06, COD 34408 mg/L, TSS 1550 mg/L, DO 0.30 mg/L, DHL 1090 μS/cm and Al 54.95 mg/L. After carrying out the electrocoagulation process, the pH value was 5.17, COD 12144 mg/L, TSS 420 mg/L, DO 0.37 mg/L, DHL 648 μS/cm and Al 231.33 mg/L at a voltage of 30 V with time. electrocoagulation 120 minutes.

“…One of the factors that can affect COD in water is the presence of inorganic molecules that interact with dichromate [28]. Dichromate in water is an oxidizing agent that causes pollutants in the form of carbon dioxide in the waters [29]. Carbon dioxide in the waters is needed in the decomposition carried out by bacteria.…”

Textile industry production activities in one of the Badas areas can have implications for the occurrence of dye liquid waste pollution in the Konto river flow. This implication leads to the public perception that there has been river pollution from textile dyeing liquid waste. In this case, public perceptions need to be analyzed as a form of river environmental monitoring activities. Therefore, public perceptions of pollution were compared with actual water quality data, especially related to dyes in river water, to link public perceptions with environmental resource management efforts. This study aims to analyze public perceptions of textile dye waste pollution and compare the analysis results with the river water quality analysis. Analysis of river water quality (dye content, BOD, COD) was conducted at five sampling points in Badas, Kuwik, Balungjeruk, and Wonorejo villages. Public perception was measured descriptively through interviews with respondents referring to the Slovin method. The analysis of public perceptions shows that the Public considers that there has been pollution of river water, mainly due to textile industry waste, along the Konto River. The results of the water quality analysis showed that dye concentrations were found at four sampling points except for Wonorejo Village. This result shows that the correlation between public perception and data on dye contamination only occurs in Badas, Kuwik, and Balungjeruk villages. In addition, the BOD/COD ratio indicates that pollution has occurred at all observation points in this study.
