Abstract

Echinoderms are an invertebrate animal consisting of 5 classes, all of its members live in the sea. Echinoderm inhabits the shallow sea to a certain depth. Tanjung Setia beach is a beach with coral substrate and seagrass which is echinoderms habitat. Based on visits ever made, it is known that this beach has many echinoderms. The number of species of this coastal echinoderms is unknown as does its diversity index. The purpose of this research is to know the species of Tanjung Setia echinoderms, along with its diversity index. This research is descriptive research, the technique used random sampling by using the combination of line transect and quadrant. Based on research that has been done that there are 12 species of echinoderms, with H’ medium. Kata kunci: indeks keanekaragaman, echinodermata, Pantai Tanjung Setia
