Gastropods communityin the Baburariverat Medan City were collected at Medan Johor and Medan Kota which consisted of 6 species of 96 ind., i.e. (1) Pomacea canaliculata [36 ind.], (2) Filopaludina javanica [5 ind.], (3) Lymnaea rubiginosa [2 ind.], (4) Tarebia granifera [11 ind.], (5) Melanoides tuberculata [35 ind.], and (6) Thiara scraba [7 ind.]. Total abundance was 39.0 ind./m2 in Medan Johor and 43.6 ind./m2 in Medan Kota. Diversity index (H') was 0.897 in Medan Johor and 0.986 in Medan Kota, classified as low diversity and severe, equitability index (E) was 0.557 in Medan Johor, classified as moderate uniform and 0.711 in Medan Kota, classified as high uniform. Dominance index (C') was 0.500 in Medan Johor and 0.463 in Medan Kota, both of which are moderately dominant. Gastropods were found to be influenced by physico-chemical parameters of water. The parameters which still supported gastropods life,i.e: temperature, turbidity, depth, pH, DO, and BOD, in contrary to strong velocity, nitrate, and phosphate.Our results then may reflect the preliminary data on gastropods assemblage in Babura river to enrich future data regarding gastropod communities in other study sites. © 2019 IOP Publishing Ltd.
