Sampling was carried out in April-May 2023. The indicators in this study are the species abundance index, diversity index, uniformity index, and dominance index. This type of research is a type of quantitative descriptive research. Determination of stations using purposive sampling technique, namely sampling based on substrate conditions and the presence of starfish (Asteroidea). The results of data analysis are presented in the form of figures and tables.
