【 摘 要 】

Coral reefs ecosystem is a complex and special coastal resources in a tropical area. the characteristics of this ecosystem are high in productivity and diversity. Panaitan island is one of the island located in Ujung Kulon National Park area with various coral reefs. This area has multi attractive potencies which can be exploited by everyone depending on personal or group interests. Coral cover data were collected using Line Intercept Transect method and mortality analysis using mortality index method. Data collection was carried out in 4 different stations with 2 different depths. The results showed that at the depth of 5 m the highest damaged area is on 1st station, with 50% damaged coral reefs. Mortality rate at the depth of 5m and 10m found at 1st station with mortality index 0.4 point and 0.44 point respectively. It is estimated that station 1 is a good area compared to the previous study that shows condition so that many exploitation by destructive.
