ABSTRACT
Community structure is a concept that studies the composition or composition of
species and abundance in a community. Coastal waters are areas with a depth of less than
200 meters and there is a littoral area located between the highest tide and the lowest low
tide or called the intertidal area. One of the community of organisms in this intertidal area
is gastropods. This research was conducted from December 2021 to January 2022. The
purpose of the study was to determine the structure of the gastropod community in the
coastal waters of North Rupat District consisting of species, density, diversity index,
uniformity index, dominance index, distribution pattern, and community similarity. As
supporting data in this study, several environmental parameters were also measured
which included water quality, sediment type and sediment organic matter content. The
research method used is a survey method, where sampling using the quadrant transect
method is carried out at 3 stations. Based on the results of the study found 14 species of
gastropods. The species that were found in all stations were Indothais gradata. Gastropod
density is 15.800 ind/ha. Diversity index value (H') 1.85, uniformity index (E) 0.70,
dominance index (C) 0.24, distribution pattern (Id) 3.24 is clustered, species similarity
index (Ss) between stations Tanjung Medang and Teluk Rhu 83% of species are almost
the same and between stations Tanjung Medang and Tanjung Punak 15% and between
stations Teluk Rhu and Tanjung Punak 17% are not the same. Water quality parameters
as follows: temperature 27-28oC; salinity 30-31 ppt; pH 6-7. Sediment organic matter
0.50-2.28%, sand sediment type.
Keywords: community structure, gastropods, North Rupat intertidal waters.
