This study aims to determine the community structure of macrozoobenthos including abundance, diversity, evenness and dominance of the type of macrozoobenthos in the mangrove area. The study was carried out in the District of North Insana which included the mangrove area of Temkuna Beach (station I) and the mangrove area of Tanjung Bastian Beach (station II).
