In this study, an area of 1,197 m was obtained so data collection was used for 12 plots or replications. Data analysis with measuring Margalef index (D), Relative Abundance (RA), and Variant value (V) then the data were analyzed using a distribution pattern. The results based on the research are from 9 species that have discovered the highest relative abundance of Echinoderms species in the intertidal zone of Nglolang Beach is O. erinaceus with 54...
