ABSTRACT
Many types of the coastal land use in Banten Bay have been assessed in order to know the change as evidently detected by Landsat imagery in 1994 and 2001. Image pr ocessing such as, supervised classification and various change detection techniques are performed to the satellite images. Red Green met hod showed the best result for detecting the coastal land use change. This method is suitable for detecting the increasing areas of the paddy fields and settlement. Image Differencing method is capable to detect the increasing areas in agriculture, decreasing in fishponds and natural areas. Image Ratioing method can be considered suitable for detecting the increasing area of fishponds, decreasing of paddy fields and agriculture areas. Each co astal land use type has increa sed, except for the natural area/brushwood. Most of agriculture and paddy fields areas have been converted to fish ponds
