Abstract
Coral disease now became main factor of coral degradation in the world. There is still a few report about coral disease in Kepulauan Seribu Marine National Park (TNKPS) include of white syndrome (WS) in Montipora sp. WS was characterized by white area on coral surface at several stages. WS had caused coral tissue loss and leaved bare CaCO3 skeleton that was caused by pathogenic Vibrio coralliitycus associated with other microorganisms. In this study the progress of WS calculated by measurement of the distances of WS that moved from diseased to healty coral surface. All calculations was performed used ImageJ Software. Our result showed that WS progression rate in first week was 9.06 cm2 and the second week was 2.37 cm2. Total coral tissue mortality was 12.03% for 2 weeks.

Summary
Kondisi terumbu karangsaat ini mengalami degradasi yang berfluaktuatif, tercatat pada 1998 kerusakan karang akibat mass bleaching telah menurunkan produktifitas terumbu karang (Pandolfi et al, 2003; Bryant et al, 1998). Infeksi penyakit pada karang telah mempengaruhi kondisi terumbu karang global dan menjadi salah satu faktor utama yang terdegradasinya tutupan karang (Miller et al, 2009). White Syndrome (WS) adalah jenis penyakit yang umum dijumpai menginfeksi karang jenis Montipora spp. dan Acropora spp. Johan et al, (2015), melaporkan di daerah kepulauan seribu karang yang paling banyak menunjukkan tandatanda adanya white syndrome terdapat di selatan Pulau Pramuka, Pulau Kelapa, dan Pulau Karang Bongkok. Ushijima et al (2012), melakukan pengamatan terhadap Montipora yang terkena white syndrome akut dan menemukan adanya Vibrio coralliilytycus yang berperan sebagai agen penyakit. Penelitian ini bertujuan untuk mengetahui laju infeksi penyakit white syndromepada terumbu karang Montipora sp di Pulau Pramuka, Kepulauan Seribu, DKI Jakarta
