<![CDATA[River ecosystem quality can be assessed through macroinvertebrate communities, as different taxa have different levels of sensitivity to pollution. The Kampili River in Gowa Regency is under anthropogenic pressure from surrounding domestic and agricultural activities. This study aimed to evaluate the water quality of the Kampili River based on macroinvertebrate composition and abundance using the Biotilik Index. The study was conducted in February 2024, with macroinvertebrate samples collected along the river. The organisms were identified to the family level and analyzed based on abundance percentages and the Biotilik Index (X/N). Hydropsychidae was the most abundant family, followed by Mesovellidae and Ephemerellidae. Ephemeroptera, Plecoptera, and Trichoptera (EPT) accounted for 53.19% of the total abundance, indicating relatively good ecological conditions. The Biotilik Index value of 3.11 indicated light pollution, with 47 individuals recorded. These results suggest early changes in ecological conditions associated with anthropogenic pressure. Regular water quality monitoring, waste management, environmentally friendly agricultural practices, and riparian vegetation protection are needed to maintain the condition of the Kampili River ecosystem.]]>
