Minapolitan is an area or village for aquaculture as the main business sector, supported by good water ecosystem and legalited by local goverment. Bangkong River is one of the rivers located in Minapolitan area of Menayu Village, Muntilan District. Bangkong River is the main source of water for aquaculture activities. Community structure of Macrobenthos is used to determinate water quality in Bangkong River. The research was conducted on April and June 2016 at four location, representing upstream, middle, downstream parts of the river, and fish pond. The result found 33 species consisting of 16 families and 7 classes. The most prevalent family at the four sampling sites is Thiaridae (Class: Gastropoda). Thiaridaeis one of family of macrobenthos that easily adapt to environmental conditions. Species that dominates on all four sampling sites were Melanoidestuberculata. The Values of Diversity index (H) ranged from 1,77 to 2.19. The similarity index value type (J ) ranged from 0.92 to 0.97. Dominance index value (C) ranges from 0,90 to 0.98. The abiotic parameters of water quality in the Bangkong River in four sampling locations is considerably in normal range based on Indonesian goverment regulation number 82 year 2001 about water quality for aquaculture. The average carbon content ranging from 1.42 to 8.21% and the nitrogen content ranged from 0.15 to 0.65%. Based on the data obtained in four sediment sampling locations were is dominated by fine sand with fine sand highest value of 71% in the sampling location 1. In addition to fine sand, sediment composition also consists of coarse sand with a highest score of 31% in the locations 2. By using BIO-ENV software to analysis the correlation abiotic and macrobenthos it was known that the value of the DO, and nitrogen levels are the most influential abiotic components for the abundance of macrobenthos (BIO-ENV: r = 0 91). Keywords: Minapolitan Areas, Macrobenthos, Shanon-Wiener Diversity Index (H).
