Abstract
Coral reefs are unique ecosystem and most of them are found in tropical areas. Remote sensing technology has the ability to present the information about the existence of marine resources, such as coral reefs. Remote sensing technology also provide the spatial information on wider area. This study is aimed to see how significant the effect of watersheds damage toward the condition of coral reefs because of erosion which is occurred in the upstream and sedimentation which is occurred in the downstream of the watershed. Acquisition of the data in this study used remote sensing image Landsat 7 ETM+ and Lansat 8 OLI in multi temporal, the data collection of this study used photo-quadrate technique and taking sample in the field. Spectral analysis and transformation of CTA (Classification Tree Analysis) was used to generate the level of the health of coral reefs. The method of RSI (Red Silt Index) was used to find out the degree of turbidity of the water. Analysis of the changes was done to find out the changes which were occurred on coral reefs based on the changes of turbidity that were occurred between 2000 till 2015. Based on the result, it shows that there is no effect on the changes of turbidity value toward the health condition of coral reefs in the northern coast of Sekotong Sub District 2000 till 2015. This is due to the use of RSI index or turbidity index that cannot be used in the condition of shallow water.
