| Abstract | ||||
| Batanghari River is a resource that supports economic, social, and ecological life. However, increasing human activities such as agriculture, settlements, and fish farming have contributed to nutrient inputs that have led to a decline in the quality of the Batanghari River. Integrated studies of nutrients in the Batanghari River from upstream to downstream waters and sediments are limited. The study aimed to determine the upstream-to-downstream status that occurs with different human activities along the Batanghari River based on nutrients. The study was conducted during the dry season and divided into six stations. The results of the Pollution Index (PIj) showed that the condition of the Batanghari River was slightly polluted with nutrients and unsuitable for use according to the Class I category. The highest nutrient was TOM with a range of 77.38 - 162.54 mg/l in the water column and the highest nutrient in the sediment was TN with a range of 1.56 - 5.88 mg/l. Based on the comparison with water quality standards, TP, TN, and ammonium concentrations exceeded the quality standards, especially in the middle and downstream zones with unfit categories for Class I and Class II. The high level of nutrients in the Batanghari River is a result of the high load of organic waste entering the waters and is worrying nutrient pollution in the Batanghari River as a source of water and biotic life. | ||||
