ABSTRACT
Pancuran beach is one of beaches in Karimunjawa National Park, Jepara. Pancuran Beach has a good seagrass ecosystem. Seagrass ecosystems as habitats for many marine life such as Phylum Echinodermata. One of them is Sea urchins (Echinoderms). The purpose of the research was to determine the density, composition of seagrass and abundance of sea urchins, and correlation between seagrass density to abundance of sea urchins at Pancuran beach at May 2018. Research methodology that used is observation method. The sampling method used purposive sampling method. The data in this research are the type of seagrass and the number of seagrass, and abundance of sea urchins. Seagrass density is calculated based on the category of dense, moderate and sparse by using 1x1 m transect with a 5x5 m area with 3 repetitions. Water quality parameters measured are temperature, salinity, pH, depth, and clarity. The analysis data that was calculated were diversity index, uniformity index, dominance index and regression. The result of the research found the types of seagrass in Pancuran Beach is Thalassia hemprichii, Enhalus acoroides, Cymodocea rotundata and Cymodocea serrulata. The dominant seagrass species obtained at 3 area are Thalassia hemprichii. The number of seagrass density was 320 individuals/m2, moderate density 179 individual/m2 and in the sparse density 79 individuals/m2. Sea urchin species that only have is Diadema setosum, at a dense density of 1,65 individuals/m2, moderate density of 1,92 individuals/m2 and a sparse density of 2,72 individuals/m2. Correlation between seagrass and abundance of sea urchins with r-coeff = 0,840.
