As one of the largest archipelagic countries globally, Indonesia has diverse natural resources, one of which is the coral reef ecosystem. Coral reef ecosystems are spread across almost all Indonesian waters, and Pulau Weh Sabang is one distribution area. This study aims to determine the distribution of coral reef ecosystems and test landsat 8 oli imagery accuracy in mapping coral reef ecosystems. The method used in this research is the nearest neighbour algorithm object-based classification method. The results showed that the coral reef ecosystem in Pulau Weh Sabang was divided into two classes: a healthy coral reef ecosystem class with 277.38 hectares and a medium condition coral reef ecosystem class with an area of 710.01 Ha.Keywords:Landsat 8 oliMappingDistributionCoral reefWeh Island

<strong>Assessment of Landsat-8 Classification Method for Benthic Habitat Mapping in Padaido Islands, Papua.</strong> Indonesia is the biggest archipelagic country in the world with an area of coral reefs of 39,583 km.This area has to be managed effectively and efficiently utilizing satellite remote sensing technique capable of mapping of benthic habitat coverage, such as coral reefs, seagrasses, macroalgae, and bare substrates. The technique is supported by the availability of Landsat-8 OLI satellite images that have been recording the regions of Indonesia continuously every 16 days. This research was carried out in June 2015 in parts of Padaido Islands, Papua. This area was selected due to high coral reef damages. This study utilized Landsat-8 OLI to compare two classification methods, namely pixel based and object based methods using ‘maximum 2 likelihood’ (ML) and ‘example based feature extraction’ classifications, respectively, after water column correction (Lyzenga method).  The results showed that both methods produced benthic habitat maps with 7 class covers. The pixel-based classification resulted in a better overall accuracy (47.57%) in the mapping of benthic habitats than object-based classification approach (36.17%). Thus, the ML classification is applicable for benthic habitat mapping in Padaido Islands. However, the consistency of this method must be analyzed in many diffrent locations of Indonesian waters.
