Perbandingan Sebaran Makrozoobentos Ekosistem Rekayas A Turap Dan Ekosistem Alami Pantai Lapin Desa Tanjung Punak Rupat Utara Kabupaten Bengkalis Provinsi Riau
This study aims to determine the community structure including abundance, diversity, uniformity, species similarity index, macrozoobenthos distribution patterns, and to compare the abundance of macrozoobenthos in the Tortoise Engineering ecosystem and Natural ecosystem. Sampling was conducted at the lowest tide in order to obtain a wider sampling area to facilitate sampling of macrozoobenthos. Each individual macrozoobenthos found was put into a plastic sample, then each plastic sample was labeled. As many as 11 species of macrozoobenthos were found in Lapin Beach, Tanjung Punak Village, North Rupat, Bengkalis Regency, Riau Province. There are 8 species of macrozoobenthos from the Gastropoda class, 1 species of Bivalve class, 1 species of Malacostraca class, and 1 species of Polychaeta class. The results of the analysis of macrozoobenthos community structure at the Turap Engineering ecosystem station showed a diversity index value of 0.314, a dominance index value of 0.86 and a uniformity value of 0.286. At the Natural ecosystem station has a diversity index of 6.55, a dominance index of 0.39 and a uniformity index value of 1.02.
