【 摘 要 】

The purpose of this study was to determine the Diversity Index, Similarity Index, and Dominance Index. The research location in Krukut River along 12 km. The research was conducted in March - June 2017 in 7 sampling points. Macrozoobentos obtained as many as 23 species belonging to the 9 classes are 3 types of Bivalves, 7 types of Arthopoda, 2 types of Molusca, 4 types of insects, 4 types of Oligochaeta, 2 Malacostraca, 1 Crustacea, 1 Diptera, and 1 Nematodes. The highest abundance of macrozoobentos is 10550 Ind/m2, whereas the lowest macrozoobenthic abundance is 850 Ind/m2. The range of Diversity Index (H') 0.32 - 1.80, Similarity Index (E) 0.58-1.07 and Dominance Index (C) 0.40-0.63. Therefore the result shows that Krukut River is in category medium pollution.
