Abstract
The structure of macrozoobenthos communities plays a crucial role in aquatic ecosystems because most of them are in the second or third trophic level. Components of macrozoobenthos community structure include species and abundance, species diversity index, species uniformity index, dominance index. The research aims to analyze species abundance and relative abundance of macrozoobenthos in the intertidal zone of Marabatuan Island, Kotabaru, Indonesia. The research location is on Marabatuan Island, Pulau Sembilan District, Kotabaru Regency, South Kalimantan Province. The highest relative abundance (KR) was at station 3, namely the species Ophiocoma erinaceus, from the Asteroidea class, the second highest value was at station 2 with the species Holothuria atra and at station 1 of the same species, namely Holothuria atra from the Asteroidea. The lowest relative abundance was at station 1 of the Linckia laevigata species. The Diversity Index (H') of macrozoobenthos at all stations is in the medium criteria.
