Coral reefs have undergone significant degradation as a result of the impact of human disturbance and natural factors on biodiversity and ecosystem function. The impacts ranged from an increase in the appearance of coral bleaching, coral disease, to coral death. Especially for coral disease, it is confirmed that it has contributed to the reduction of live coral cover and the productivity of coral reef ecosystems. The coral disease can be epidemic due to environmental pressures, both anthropogenic and natural, as well as infection from pathogenic microbes. Recently in several places, including Semak Daun Island, Seribu Islands-Jakarta, it was reported that the condition of coral reef cover had increased. However, a high percent of coral cover can increase disease prevalence and abundance. Acropora coral is a type of coral that is commonly found on Semak Daun Island. However, these corals are very susceptible to stress so that the threat of disease is high. So it is necessary to conduct a study that aims to determine the type and prevalence of diseases that disturb Acropora coral in Semak Daun Island, Seribu Islands, Jakarta. The field survey was carried out for coral observation using the line transect method at four stations. Coral disease identification refers to the Coral Disease Handbook and Underwater Cards for Assessing Coral Health. Observation objects, both coral species, and signs of disease were documented using underwater cameras. The study results indicate that 15 types of Acropora corals were dominated by A. humilis. Meanwhile, two groups of diseases were found, namely Tissue loss - Predation caused by the COTS and Drupella, while those from the Compromised Health group included RFA, SD, and Sponges.
