Abstract

Rivers flowing through industrial areas are exposed to anthropogenic pressures that may degrade water quality and limit their capacity to receive additional pollutant inputs. The Batang Jujuhan River in Jambi Province flows through an industrial zone and is intensively used by local communities, making a quantitative assessment of its water quality status essential for effective river management. This study aims to evaluate the water quality status of the Batang Jujuhan River using the Pollution Index (PI) method and to estimate mixed pollutant concentrations at an industrial wastewater discharge point using a mass balance approach. Water samples were collected at upstream and downstream sections of the river and analyzed for physical, chemical, and biological parameters by an accredited laboratory, with results compared to Class II water quality standards based on Government Regulation No. 82 of 2001. The results show that Pollution Index values range from 0.7 to 0.9, indicating good water quality conditions at both locations. Mass balance analysis indicates that combined concentrations of key parameters, including COD, TSS, and oil and grease, remain below the applicable quality standards under observed river discharge conditions. These findings suggest that current pollutant inputs do not exceed regulatory thresholds and provide a quantitative baseline for water quality management in industrial river systems.
