Relationship of Water Parameters and Macrozoobenthos Community Structure in the Nature Tourism Park of Mangrove Angke Kapuk Dki Jakarta

Macrozoobenthos is a sedentary benthic organism and has very slow movement. Therefore it will directly be affected if environmental changes exist. The purpose of this study was to determine the relationship of waters parameter with the community structure of macrozoobenthos at the Nature Tourism Park of Mangrove Angke Kapuk. Measurement of physical and chemical parameters, as well as a sampling of water, sediment, and macrozoobenthos, were carried out in situ. Nutrient concentrations and sediment characteristics were analyzed using spectrophotometric and granulometric methods, respectively. Macrozoobenthos were identified and then analyzed. Relationship of waters parameter with macrozoobenthos community structure analyzed by regression analysis. From the results of the study were identified seven species of macrozoobenthos belong to three classes (namely Bivalvia, Gastropods, and Polychaeta). The results for correlation between the macrozoobenthos abundance with pH, salinity, chlorophyll-a, and silt were very strong positive; with DO is strong positive; with ammonia and n-total were very low positive; with gravel, was very strong negative; with sand, was moderately negative; and with temperature, phosphate, nitrate, and nitrite negative were very low negative.
