Abstract

This research aims to update ecosystem data in the coastal zone as one of the coastal area management activities. Integrated coastal area management or better known as Integrated Coastal Zone Management or ICZM for short is the management of the utilization of natural resources and environmental services contained in coastal areas. The update focuses on updating the thematic map of coral reef distribution in conservation areas in the Bangka Belitung Islands Province. The mapping method uses Sentinel-2A image processing. The final result presents the updated RZWP-3-K map and also shows a map of coral reef distribution in conservation areas of 12,146,100 m2 in the Belitung region, 12,412,000 m2 in the South Bangka region, 4,839,000 m2 in the Central Bangka region, 3,269,800 m2 in East Belitung, and 461,900 m2 in the Tuing region. The classification results obtained an overall accuracy value of 73.82%.
