Abstract

The Gembolo River plays a crucial role in supporting food security and the community's economy. However, industrial activities, intensive agriculture, and settlements have led to a decline in water quality due to the influx of various pollutants. This research aims to identify physical, chemical, and biological parameters; analyze water quality indices and pollution levels; and formulate water pollution control strategies for the Gembolo River in Mojokerto Regency. Samples were taken at five points along the river from upstream to downstream, and water quality parameters were tested. The pollution status was analyzed using the STORET method, the Pollution Index (IP), and the Shannon-Wiener diversity index. Control strategies were formulated using an Ecohydraulics analysis approach. This approach is used to integrate physical and biological aspects in river flow management, to achieve a balance between human needs and the sustainability of aquatic ecosystems. Based on the STORET method, water quality at point 1 was categorized as lightly polluted, point 2 as moderately polluted, and points 3 to 5 as heavily polluted. Meanwhile, the IP method showed point 1 in good condition, and points 2 to 5 in the lightly polluted category. The Shannon-Wiener diversity index showed moderate values at all points, without dominance of specific macrozoobenthos species, reflecting a relatively stable benthic ecosystem. Based on these results, pollution control strategies are tailored to the conditions of each segment to achieve sustainable water resource management. With effective monitoring, appropriate treatment technologies, and community-based approaches, the water quality of the Gembolo River can be maintained and preserved to support a healthy ecosystem. Keywords: Gembolo River, STORET, Pollution Index (IP), Shannon-Wiener, Ecohydraulics
