ABSTRACT
Lake Maninjau which is located in West Sumatra Province has been designated as one of the national priority lakes among 15 other lakes. Water quality conditions of Lake Maninjau is influenced by the condition of the water quality of the streams that flow into the lake. The present study aimed to determine the condition of the water quality of the inlet stream of Lake Maninjau by using macrozoobenthos as bioindicators. This study was conducted in June and August 2019 in four inlet streams of Lake Maninjau including the Koto Kaciak, Kurambik, Kularian, and Ranggeh Bayur streams. A sampling of macrozoobenthos was carried out in the upstream, middle, and downstream using Surber nets on rocky and sandy substrates, and Ekman Grab on muddy substrates. Based on the results of this study, macrozoobenthos were found in the four inlet streams with a range of 5-25 families and 4-10 orders and classified into eight classes including Insects, Clitellata, Malacostraca, Bivalvia, Gastropods, Polychaeta, Hirudinea, and Turbellaria. The results of the Spearman correlation analysis between biological metrics and the Water Quality Index (WQI) show that the SIGNAL, EPT, and LQI metrics have a very strong correlation with r values > 0.7 (p < 0.01). The SIGNAL metric has the highest correlation (r = 0.752) indicates the inlet streams of Lake Maninjau which are lightly to heavily polluted. Metrics of macrozoobenthos communities such as SIGNAL, EPT, and LQI can be applied to complete the assessment of the physicochemical parameters of inlet streams of Lake Maninjau
