Abstract

This research was aim at performing analysis of various vegetation indices of Landsat Thematic Mapper satellite data to identify the distribution of coral reef in Enggano Island, District of North Bengkulu, Bengkulu Province. This research is based on the realities that: 1. Vegetation indices analysis are generally only used for objects on the land; 2. Analysis of coral reef using remotely-sensed data are mainly use multispectral classification technique, Shallow Water Image Mapping, and Lyzenga‘s. Materials used were mainly Landsat Thematic Mapper satellite data and Map of Joint Operation Group. GIS Programs used to analyze were ILWIS (Integrated Land and Water Information Systems) version 3.4 and ArcView version 3.5. Methods applied was by performing analysis of various vegetation indices of Landsat Thematic Mapper satellite data, which are RVI (Ratio Vegetation Index), NDVI (Normalized Difference Vegetation Index), and SAVI (Soil Adjusted Vegetation Index). The result of every analysis of vegetation index then was used as a base for on-screen digitizing in areas where the boundary of coral reef existence is probably exist such that can be gained digital data of coral reef. The accuracy of the result was checked by overlaying it (overlay analysis) onto Map of Coral Reef derived from topographic map published in 1942 (Map of Joint Operation Group, and used as a Reference). Analysis of vegetation index is said to be “Good” if the accuracy is ≥ 80% (according to Daels and Antrop).The result of research shows that the overall accuracy were 67.60% (RVI), 65.40% (NDVI), and 73.16% (SAVI). It revealed that the accuracy of coral mapping using all vegetation indices can be said as ―Not Good‖.
