摘要：The aim of this study was to determine hard coral cover at the time before (2015), during (2016) and after coral bleaching (2017) in Krueng Raya, Aceh besar. This study was conducted on April 2017 in Krueng Raya, Aceh Besar. Data collection was carried out at 3 observation stations using the PIT (Point Intercept Transect) method which included : Fort Inong Balee, Ahmad Rhang Manyang, and Lhok Mee. The results showed that the average percentage of hard coral cover in 2017 was 22.90% (bad category), it was lower than in 2016 32.43% (medium category) and in 2015 was 52.83% (good category). There were found 16 genera of coral (2015), 18 genera of coral (2016), and 8 genera of coral (2017). Mortality Index (MI) in 2015 ranged between 0.02-0.20 (low coral mortality rate), in 2016 ranged between 0.13-0.49 (low coral mortality rate), in 2017 ranged between 0.63-0.79 (high coral mortality rate). The results of this study indicate that the percentage of hard coral cover has decreased to reach 50% due to coral bleaching in the waters of Krueng Raya Aceh Besar.
