Laundry waste water is a part of domestic liquid waste and its classified as grey water. Liquid waste from laundry business containing pollutants such as BOD, COD, TSS, Total Phosphate, and Methylene Blue Active Substance (MBAS) that can give negative impact to the environment if it is not treated first. The purpose in this study was to analyze the influence of detention time to eficiency of decreasing pollutant concentration by using Rotating Biological Contactor (RBC) methods. The RBC used the palm fiber as the media. Variation of detention time in this study was 1, 3, 5, 7, 9, 11, 13, and 15 days. Linear regression was used to analysed the effect of detention time to pollutant concentration decreased. The result showed that the elimination efficiency of BOD, COD, TSS, Total phosphate and MBAS was 88%, 87%, 87%, 88% and 96%. The regression analysis results showed that there was a significant relationship between detention time and efficiency of decreasing pollutant parameters concentration (BOD, COD, TSS, Total Phosphates) of laundry waste by using RBC, but has no significant relationship in MBAS parameter.

Some of tofu industries in Jambi City are household industries, where the wastewater from processing unit was disposed of into the environment without treatment. This study aims to analyze the effect of detention time and the effectiveness of decreasing COD concentration and pH neutralization on wastewater of tofu industry using a sub surface flow - wetlands (SSF-wetland) system combined with a filtration system. The plant selected in this study was water jasmine (Echinodorus palaefolius). Variables of waste water detention time in the reactor are 5, 7, 9, 11, 13 and 15 days. Decreasing of COD concentration and increasing of pH were analyzed by comparing influent and effluent from wastewater samples, also the effect of detention time on the effectiveness of parameter reducing on each system. The water quality standard refers to the regulation of the Minister of Environment and Forestry Number 68 Year 2016. The results showed excellent performance from a combination of the two systems where an initial pH with range of 3 increase to pH 6.5-7. The efficiency of reducing COD concentration reached 47-94% during the 15-day detention time with concentration value 125 mg / l, close to the standard value 100 mg / l. The residence time has more significant effect on the reduction of COD in the SSF-Wetland system than the filtration system. Whereas in pH parameters, the residence time does not have a significant effect on both systems.

PERUMDA Drinking Water Tirta Mayang Jambi City has two processing systems, namely a manual system and SCADA system (suvervisory control and data aqustion) both systems have a manual processing capacity with a capacity of 300 l/d while the SCADA system with a capacity of 600 l/d. The result of the two water treatment systems show differences in terms of operating units and process units as well as water quality parameters include pH, residual chlorine and turbidity. The purpose of this research is to know the difference between manual system and SCADA system water treatment processat PERUMDA drinking water Tirta Mayang Jambi City. The method used is comparative quantitative analysis which compares the existence of one or more variables in two or more different samples, or at different times. The results showed that there was a significant difference in the burbidity parameter at a percentage of 10-40% between the manual system and the SCADA system, the effect of seasons also had an effect on turbidity. Where in the rainy seasons the quality of water turbidity increases significantly compared to the dry season.

One of the biggest environmental issues today is plastic waste. This waste cannot be avoided and continues to increase which in its decomposition takes 50-100 years and will be fragmented into smaller forms called microplastics. Microplastic measuring < 5 mm with various shapes. The people of the Nipah Panjang area dispose of plastic waste into the Batanghari River which is likely to cause microplastic content. To determine the number of microplastics, it is necessary to identify the abundance of microplastics found in the Nipah Panjang area on the Batanghari River using quantitative methods. The tool used is Planktonet mesh 150 with a diameter of 20 cm. The sampling process was carried out for one day with two samplings, namely in the morning at low tide at 09.00-11.00 WIB and in the afternoon at high tide at 15.00 WIB. The study's results were sampling in the morning at low tide with 327 microplastic particles and the highest in the afternoon at high tide, namely 443 microplastic particles. The temperature in the morning and evening ranges from 29°C - 32°C. The results showed that four types of microplastics were found, namely the type of fiber, filament, fragment, and granule. From the four locations of Sungai Air samples, the most microplastic fragments were found with a total of 353 particles, the second most were filament types with a capacity of 191 particles, the third type of fiber with a total of 186 particles, and the least types of granules with a total of 40 particles. Microplastic at low tide is lower than at high tide. The abundance of microplastics from the four sampling locations of river water is 25,666.67 particles/m3.

Biochar is a solid material formed from the carbonization of biomass. Biochar is the result of the conversion of organic waste by using the incomplete combustion method with a limited oxygen supply (pyrolysis). Meanwhile, the rubber scrap waste from the production of crumb rubber has not been utilized much other than as a mixture of fertilizer in the soil. This study aims to analyze the effectiveness of biochar as a peat water filtration media and the effect of biochar thickness on removal efficiency. Variations used are 100% biochar, 75% biochar – 25% silica sand, 50% biochar – 50% silica sand with three times repetation in each variation. with peat water test parameters are pH, color and organic matter (KMnO4). Parameters tested were pH, color and organic matter (KMnO4). The results showed that biochar was effective in neutralizing pH where the initial pH increased to 7.2, 4.2, color removal up to 75% and organic matter (KMnO4) up to 83%. The best variation is achieved at a ratio of 50% biochar – 50% silica sand. Variations that use 100% biochar actually provide lower removal efficiency. The combination of biochar with silica sand can further improve pollutant removal in filtration system.
