Paper Title
Coral Reef Communities In The Sand Substrate Of South Java Sea

Pantai Papuma facing Indian Ocean directly and this condition gave an extreme environment such as high sand sedimentation, high wave, strong current, and high tidal range. The aim of this study was to descript coral reef condition in this area, include coral and reef fish as main builder of coral reef ecosystem. To address that pupose We used line intercept transect method (LIT) and under water visula census methods along 100. All data was taken from 3 station they were: station 1 (825'59.26"S 11333'15.07"T), station 2 (826'0.93"S 11333'17.53"T) and station 3 (826'2.02"S 11333'20.06"T), in 3- 12 m depth. The result showed that coral reef in Papuma was dominated by Acropora branching and coral branching went form family Acroporidae. The total coverage of these coral was 30%. Other dominat substrate in pantaiPapuma was sand, it has 26.9% of coverage. Based on this research We found about 137 of reef fishes, 19% of them was composed by indicator fish (Chaetodontidae). Six species of Chaetodontidae were common in pantaiPapuma, they were Chaetodon baronessa, C. Kleinii, C. Decussatus, C. Ephippium, C. Trifasciatus, and Heniochusvarius. Chaetodontiids fish are wellknown as environental indicator for coral reef ecosytem and also represent of healthy coral reef. Almost all chaetodontiids are coral dependent high coral cover and dense coral in an ecosystem usually be followed by increasing fish indicator as well. Ten types of coral life form was defined in pantaiPapuma and the life coral coverage about 39.9% in average. Keywords - Acropora Branching, Chaetodon, pantaiPapuma, Indian Ocean, South Java.
