Penyakit karang semakin diakui sebagai ancaman signifikan terhadap ekosistem terumbu karang. penelitian ini bertujuan untuk mengidentifikasi dan menganalisis jenis-jenis penyakit karang yang ada di kawasan konservasi perairan pisisi, yang terletak di kabupaten simeulue, aceh. pengumpulan data dilakukan dengan menggunakan metode belt transect dengan total panjang transek 150 meter. kelimpahan rata-rata penyakit karang di seluruh lokasi penelitian adalah 0,005 kol/m². sebanyak 15 jenis penyakit karang teridentifikasi di 19 stasiun pengambilan sampel, termasuk predasi ikan, predasi crown-of-thorns starfish, ulcerative white spots, white syndromes, atramentous necrosis, serta berbagai anomali pertumbuhan seperti stripes, spots, patches, pigmentation response, trematodiasis, invertebrata galls, dan dampak dari competition cyanobacteria, sponges, red filamentous algae, dan sediment damage. di antara ini, pigmentation response merupakan penyakit yang paling umum yang terutama mempengaruhi bentuk pertumbuhan karang masif. kata kunci: penyakit karang, kawasan konservasi perairan

Coral diseases are increasingly recognized as significant threats to coral reef ecosystems. This study aims to identify and analyze the types of coral diseases present in the PiSiSi Marine Conservation Area, located in Simeulue Regency, Aceh. Data collection was conducted using the belt transect method across a total transect length of 150 meters. The average abundance of coral diseases across the study sites was 0.005 col/m². A total of 15 types of coral diseases were identified at 19 sampling stations, including fish predation, crown-of-thorns starfish predation, ulcerative white spots, white syndromes, atramentous necrosis, as well as various growth anomalies such as spots, patches, stripes, pigmentation response, trematodiasis, invertebrate galls, and impacts from competitive cyanobacteria, sponges, red filamentous algae, and sedimentation. among these, pigmentation response was the most prevalent disease predominantly affecting massive coral growth forms.
