Disposal of batik waste into the environment without treatment causes pollution. Liquid waste from batik production contains pollutants and causes a decrease in the quality of river water. The decrease in water quality affects the life of macrozoobenthos. The purpose of this study was to determine the structure of the macrozoobenthos community in the Meduri River. This study used a quantitative descriptive method. Sediment was taken using an ekman grab. Macrozoobenthos were identified, and community structure analysis was carried out. The results obtained showed that there were two genera of macrozoobenthos found in the Meduri River, including Melanoides and Bithynia. The level of diversity and evenness was relatively low; there was a dominance of species in the community.
