Abstract

The development of the quality and quantity of clean water is one of the environmental infrastructure developments that needs attention, because it is one of the most important resources for the community. Water is all water contained in and derived from water sources both above and below the ground surface. This study aims to determine the existing condition of raw water sources and provide policy direction for the raw water sources of the Mangetan River Kanal-3, Gedangan District for the availability of clean water. The method used is descriptive quantitative with laboratory analysis techniques and AHP (process hierarchy analysis). Data collection was carried out by taking water sample points from the Mangetan River Kanal-3, secondary data and in-depth interviews with the Irrigation Service and communities around the river. The results showed that the Mangetan River Kanal-3 with Color parameters and E-coli still did not meet the quality requirements for raw water sources. As for the parameters of acidity (PH), temperature, turbidity, and odor from laboratory test results, they meet the quality requirements for raw water sources. The main policy priority directives implemented for the availability of clean water from the raw water of the Mangetan River Kanal-3 are to pay attention to the quality, continuity and quantity of water. The policy implication obtained from this research is how the community protects the environment by not throwing garbage or other waste into the river so that the river can be used as raw water for the availability of clean water and meets the criteria for clean water according to quality standards.

Abstract

Laundry wastewater contains high levels of Chemical Oxygen Demand (COD) and phosphate (PO4), contributing to water pollution and eutrophication. This study investigates an integrated treatment approach using poly-aluminum chloride (PAC) coagulation and activated carbon adsorption to improve wastewater treatment efficiency. The research aims to determine the optimal PAC dosage (10% and 15%) and stirring time (0, 5, 15, 30, and 45 minutes) for maximizing COD and PO4 removal. A batch reactor system was used to conduct the treatment process, and the analysis followed the Indonesian National Standard (SNI) methods. The results demonstrated that the highest removal efficiencies were achieved with a 15% PAC dosage and a stirring time of 45 minutes. Under these conditions, COD levels were reduced from 2189.62 mg/L to 143.47 mg/L, achieving a 93% reduction. Similarly, PO4 levels decreased from 94.33 mg/L to 5.18 mg/L, corresponding to a 96% removal rate. These findings indicate that the combination of PAC coagulation and activated carbon adsorption is a highly effective treatment method for reducing pollution in laundry wastewater. This hybrid approach meets environmental discharge standards and presents a sustainable solution for large-scale wastewater treatment applications.

Abstract

Hybrid Anaerobic Baffled Reactor (HABR) is a development technology from the Anaerobic Baffled Reactor (ABR), which was already known as a technology that is successful in treating domestic waste. Aims: The objectives of these studies were to investigate the efficiency of reducing BOD and phosphate levels in HABR with zeolite (ZE) and activated carbon (AC) media. Methodology and Results: HABR reactor made of acrylic material with a size of 90 cm x 20 cm x 30 cm. The reactor designed has 7 compartments, with details the first 5 compartments are suspended growth microorganism reactors and the next 2 compartments are attached growth microorganism reactors. Conclusion, significance, and impact of study: The result of the research showed that the efficiency of reducing BOD concentration in the reactor with ZE and AC media were 59.30% and 65.12%, respectively. The final BOD concentration in the AC reactor is 30 mg/L, this value meets the domestic wastewater quality standard required by East Java Governor Regulation Number 72 of 2013 concerning Wastewater Quality Standards for Industry and/or Other Business Activities. The final BOD concentration in the ZE reactor exceeded the required quality standard with a value of 35 mg/L. The final phosphate levels of the two reactors meet the wastewater quality standards for business and/or laundry activities with a maximum phosphate concentration of 10 mg/L. The final phosphate levels in the ZE and AC reactors were 3.74 mg/L and 8.79 mg/L, respectively. The efficiency of phosphate removal in ZE and AC reactors were 70.58% and 30.87%, respectively.
