KELIMPAHAN MAKROZOOBENTOS EPIFAUNA PADA PERAIRAN UPANG, BANYUASIN, SUMATERA SELATAN
Mangrove ecosystems are important coastal resources that provide habitats for various aquatic biota. The abundance and diversity of macrozoobentos can reflect the quality of the environment. This research was conducted in Upang Waters, Banyuasin, in October 2024–January 2025, including macrozoobentos sampling, measurement of water and substrate parameters, identification of biota, and sediment analysis. The results showed 6 types of macrozoobentos with a total of 37 individuals. The species that dominates the entire station is Neritona juttingae (16 individuals) and the highest abundance is found at Station 2 (11 individuals). Biodiversity values correlate with mangrove conditions and environmental parameters such as temperature, salinity, pH, currents, and substrates. The PCA analysis with two main factors (F1 and F2) explained 79.65% variation, with F1 being influenced by the substrate and DO, while F2 was related to soil pH, water pH, and ecological index. The distribution of macrozoobentos is influenced by a combination of water quality and substrate, so it can be used as an indicator of the health of mangrove ecosystems.
