Macrozoobenthic community structure in the mangrove ecosystem of Teluk Bogam Village, Central Kalimantan

The mangrove ecosystem in Teluk Bogam Village plays an essential role in maintaining the balance of the coastal environment. Variations in the utilization of mangrove areas have the potential to cause differences in water quality conditions. To date, no study has specifically examined the macrozoobenthic community structure in Teluk Bogam Village. This study aims to analyze the macrozoobenthic community structure within the mangrove ecosystem of Teluk Bogam Village, Central Kalimantan. Sampling of macrozoobenthos and water quality observations were conducted in March, June, and September 2024, as well as in January 2025, at three observation stations. Data analyses included assessments of macrozoobenthic community structure and Principal Component Analysis (PCA). Macrozoobenthos in the study area consisted of the classes Gastropoda, Bivalvia, and Polychaeta, with the genus Cerithium being the most dominant. The community structure was categorized as stable, characterized by moderate diversity (H'=2.04-2.06), high evenness (E= 0.92-0.97), and low dominance (D = 0.13-0.14). The PCA results indicated that macrozoobenthic density exhibited a strong association with water quality parameters, particularly turbidity and total suspended solids (TSS).
