Macroinvertebrate is one of the invertebrate animals that live in the bottom of the water that can be used to assess the quality of river water. The purpose of this study was to determine the water quality based on the diversity of macroinvertebrates found in the waters of the Amprong River Basin, Kedungkandang District and can be used as a source of learning biology. The approach used is the approach approach. The type of research used is descriptive qualitative using exploratory methods. The study was conducted at 3 stations with macroinvertebrate sampling carried out 3 times in a row. Results Based on the research, the level of diversity was low at stations I, II and III. The domination index of stations I, II, III (high). The evenness index at stations I, II, and III is low and the community is depressed. The temperature at station I and III (optimal), the temperature at station II (not optimal). pH at all 3 stations (optimal). The speed of the 3rd current is classified as a slow current. Station I has low water turbidity, while stations II and III have high water turbidity. BOD at 3 stations was lightly polluted, DO station I was polluted while stations II and III were moderately polluted, TDS at 3 stations (good), and TSS values at station I were not polluted while stations II and III were lightly polluted. 467 macroinvertebrates were recovered with species, namely Sulcospira testudinaria, Caridina gracilipes, Parathelphusa convexa, Dermogenys pusilla
