Ekosistem terumbu karang merupakan salah satu organisme laut yang rentan terhadap perubahan lingkungan perairan. Salah satu dampak akibat perubahan lingkungan tersebut adalah munculnya berbagai penyakit dan gangguan kesehatan karang. Penelitian ini bertujuan untuk mengetahui kondisi terumbu karang dan mengindetifikasi jenis-jenis penyakit dan gangguan kesehatan yang mengancam ekosistem terumbu karang di perairan Desa Langgapulu. Metode transek garis line intercept transect sepanjang 50 m digunakan untuk menggambarkan kondisi terumbu karang dengan melihat persentase penutupan karang hidup, karang mati, alga, dan keberadaan biota lainnya. Penurunan kualitas lingkungan perairan sangat berperan terhadap munculnya berbagai penyakit dan gangguan terhadap kesehatan karang, yang berdampak pada gangguan secara fisiologis bagi biota karang.

Font Size. Abstract Damage to coral reefs on Tegal Island has an impact on reducing coral reef habitats, so monitoring needs to be done. Monitoring is done by analyzing the extent and changes by utilizing remote sensing technology to map the existing conditions.

The data used are Landsat imagery in , , and Digital image processing is done starting from image correction, lyzenga algorithm calculation, image interpretation and field validation, and accuracy testing of coral reef habitats using a confusion matrix. The results showed that there was a change in the area of coral reefs from to The coral reef class experienced a reduction of Coral classes that changed into sand classes were 9.

The class of sand that turned into coral reefs was 2. The biggest change is the change in the coral reef to sand covering an area of 9. In the other classes, the biggest change in area was seagrass change into sand covering an area of 5. Keywords coral reefs; lyzenga algorithm; landsat imagery.
