Structure communities of macrozoobenthos in mangrove tourism area, Wongsorejo sub-district, Banyuwangi regency, East Java

Macrozoobenthos is an organism that lives on the surface or in liquid sediment. Macrozoobenthos is one of the most important organisms for marine and coastal ecosystems. This study aimed to determine the value of the community structure of macrozoobenthos existing in Mangrove Center Bengkak, a subdistrict of Wongsorejo, Banyuwangi regency. Sampling was conducted on three stations with different location characteristics. The community structure was measured by Shannon's diversity index, Equitability index, and dominance index. The results of this study obtained Shannon's diversity index of 0.51, equitability index of 0.12, and dominance index of 0.76 at Station 1. At station 2, Shannon's diversity index of 1.19, equitability index of 0.39, and dominance index of 0.36. While at station 3, it was obtained that Shannon's diversity index of 1.64, equitability index of 0.85, and dominance index of 0.31.
