Abstract

Seagrass is a group of flowering plants found along the coast. Seagrasses become one of the habitats of the Ophiuroidea group. The study was conducted at Cikabodasan Beach, Garut. The aim is to determine the correlation of seagrass density with abundance of Ophiuroidea. The research method used is descriptive correlational. Samples were taken as much as 30% of the length of the Cikabodasan beach. The sampling technique was done by purposive sampling where 9 line transects were installed with 90 squared transects measuring 1 x 1 m2 in 3 stations. From the results of the study obtained an average density of two species (Thalassia hemprichii, Cymodocea rotundata) of 346.23 individuals / m.2 This density is included in very tight criteria. While the abundance of Ophioderma longicauda (3.33 individuals / m2) is included in the less category. From the results of statistical calculations with the Pearson correlation test shows the correlation coefficient of 0.834. These results indicate that there is a significant correlation between seagrass density and Ophioderma longicauda abundance.
