This study aims to analyze Brantas River's quality through the Biotilik method by utilizing macrozoobenthos as a bioindicator. The study was conducted in January 2020. Determination of the sample location was done by purposive sampling. There were three sampling stations, namely in Coban Talun, Vinolia area, and Jodipan Tourism Village (KWJ) area. Data analysis of determining the Water Pollution Index (WPI) was done by calculating the macrozoobenthos tolerance index found at each station. The Water Pollution Index in Coban Talun is three so that it is clean and mildly polluted. The identified families are Tipulidae and Baetidae. The Water Pollution Index in the Vinolia Region and the KWJ Region is 2, indicating it as dirty and rather heavily polluted waters. The discovered families are Lymnaeidae, Thiaridae, Buccinidae, Parathelpusidae, Corbiculidae, and Chironomus. Vinolia Region and KWJ Region are close to the settlement. The closer to the settlement of the water quality tends to be polluted because the water contaminated by the waste from the human activities near the river. © 2021 Author(s).
