Sea urchin is essential in water ecology and food chain. In the food chain, sea urchin has the role as herbivore, omnivore, or detritus consumer to process the organism waste. The study was aimed to determine the correlation of organic materials of water-base substrate to the abundance of sea urchin in Krakal Beach, Yogyakarta. The research was performed in October-November 2014 in Krakal Beach, Yogyakarta and the organic matter analysis was conducted in the Laboratory of Environmental Engineering, Faculty of Engineering, Diponegoro University. The sampling method on sea urchin abundance was transect quadrant of 1 x 1 meter with 50 m length and organic matter analysis was gravimetric analysis method. The result obtained from the study is that the organic substance of Krakal Beach ranges between 4,09 – 4,71% in station 1, 3,65 – 3,98% in station 2, and 5,04 – 5,60% in station 3. There are 3 species of sea urchin in Krakal Beach namedStomopneustus sp, Echinometra sp, Echinometra mathaei . The abundance of sea urchin is 148 / 150 m 2 and 157/150 m 2 in station 1, 161 / 150 m 2 and 172/150 m 2 in station 2 and 174 / 150 m 2 and 90/150 m 2 in station 3. Based on the regression test, it can be said that the water-base substrate and the abundance of sea urchin although each tended to rise. }, issn = {2721-6233}, pages = {148--155} doi = {10.14710/marj.v4i3.9332}, url = {https://ejournal3.undip.ac.id/index.php/maquares/article/view/9332} }
