“…The high TDS value in the downstream or station 4 because of domestic, agricultural, fishery, and industrial waste flows from upstream to downstream. The TDS values measured at the four sampling locations are still in the category of natural waters, which are usually less than 500 mg/L (Moran, 2018). In addition, TDS value in Cihampelas River was still below the class 2 river water quality standard of 1000 mg/L in GR No.…”

The Cihampelas River is one of river that crosses the Regency and City of Bandung, West Java, with a length of 8.5 km. This study aims to assess the water quality status of Cihampelas River based on the STORET method and Pollution Index. The research was conducted at four stations based on the level of anthropogenic activity from July to September 2016. Measurements of the physical and chemical parameters of the waters were carried out five times at two-week intervals. Water quality status was assessed using the STORET method and Pollution Index based on the parameters TDS, TSS, pH, DO, BOD, COD, nitrate, nitrite, ammonia, and total phosphorus (TP). Using the STORET method, shows a score of -20 to -46 in the category of moderately to severely polluted waters. Based on the Pollution Index method, the waters of the Cihampelas River show lightly to severely polluted conditions with a score of 1.14 to 44.66. The water quality status of the Cihampelas River shows a decreasing trend from the upstream to the downstream.

“…Total dissolved solids (TDS) measure the water samples’ organic matter and inorganic salts [ 58 ]. Moran (2018) mentioned that TDS above 500 mg/L is not suitable to use as drinking water [ 58 ]. Based on the findings, TDS from before treatment (705.67 ± 12.60 mg/L) and after 5 days of treatment was reduced in all treatments, including control (582.67 ± 5.55 mg/L), thus indicating that bacterial-based bioremediation was developed into nonsterile synthetic wastewater.…”

Textile exchange is a popular term in the textile industry and has incorporated Sustainable Development Goals (SDGs) into its strategy for transformation. The advance of Industrial Revolution 4.0 digitised the textile industry and incorporated artificial intelligence (AI) into operation and supply chain to enhance production and improve product quality in different downstream processing. Malaysia’s textile industry has largely continued to contribute to the domestic economy. In the textile industry, refinement treatment is crucial to avoid water pollution derived from dye, organic pollutants, and heavy metals. Wastewater derived from textile industries must perform a pre-treat before discarding into the natural environment, as the excess dye in textile wastewater negatively impacts the environment. Untreated or inadequately treated wastewater and discharge to nearby water sources contribute to disease increase. Therefore, this study aims to elucidate microbiota biodiversity that can significantly remove or break down the dye in wastewater from the textile industry. This study selected two cationic dyes, crystal violet (CV), and methylene blue (MB). Through the findings, microbial consortium derived from the fermented bio-waste show no significant difference in the decolourisation of wastewater polluted with CV (< 13.53%). In contrast, the microbial population generated from fermented bio-waste showed remarkable outcomes on MB decolourisation up to 88.52% in 3 days of treatment. In the absence of laccase in fermented bio-waste, microbial consortium produced from the fermented bio-waste is ineffective in decolourising the wastewater containing CV compared to MB.

Water rivers Lematang commonly used by the community to meet the needs of households and industry around the region . The industry that uses Lematang river water is PLTU as its raw material for production . Apart from that, PLTU also produces liquid waste. The liquid waste comes from ( wast water treatment plant ) which can still be utilized because it has a turbidity value that is still below the max 5 NTU and the pH is still between 6 to 9 . Regarding this,power plant power plant Banjarsari apply the principles of waste control carefully and integrated namely Systems Wastewater Treatment ( Waste Water Treatment Plant ) . In the processing process, it acts as a purifier for a mixture of Lemaang river water and wastewater. Menggunakan coagulant (Poly Aluminum cloride) so it can be reused as water the additional production. The results showed that the mixture of lematang river water with waste water (wast water treatment plant) was 60% : 40% , this indicates the use of the optimum dose as production water. waste water can be used as additional water to be used as production water because the pH value is 7.65; conductivity 187.6; turbidity 4.45; and silica 1.92 . Based on the results of research by utilizing river water and waste water the most effective is the dose ratio of 60%: 40% .
