Macrozoobenthos Community Structure in Mangrove Forest Ecotourism Area Karangsong Indramayu Regency, West Java

Abstract

This research aims to analyze the diversity of macrozoobenthos species and density in mangrove ecotourism waters Karangsong Indramayu Regency West Java. The research was conducted in West Java starting from January 2021 to March 2021. This research method uses primary data in the form of physical and chemical data to measure the density, diversity and uniformity of macrozoobenthos. Data retrieval technique uses Purposive Sampling in the determination of 3 stations and 4 repetitions. The results of the research found 15 species of Makrozoobenthos that live in mangrove ecosystems namely Telescopium telescopium, Balanus perforates, Clypeomorus zonata, Cassidula aurisfelis, Cypraea leucogaster, Gyrineum natator, Polinices powisianus, Perna viridis, Placuna placenta, Tellina sp, Gari sp, Meretrix meretrix, Dossinia sp, Saccostrea cucullate and Anadara transversa. The density of macrozoobenthos ranges from 294 – 548 ind/m2. The diversity index of macrozoobenthos at stations 2 and 3 is in the medium category with a value of 2.44 and 2.822 and the diversity at station 1 is in the high category with a value of 3.10. Uniformity values range from 0.84 – 0.891 with a high category. The relationship of Water Quality with Makrozoobentos has an R2 value of 90% water quality can affect the life of macrozoobenthos and as much as 10% is influenced by other factors.
