【 摘 要 】

This research aims to determine changes in land covers and its effects on the growth of sediment in Cacaban Reservoir, Kabupaten Tegal, Jawa Tengah. Descriptive method with random sampling is used to determine land cover changes and purposive sampling is used to determine water sampling on 3 inlets and water body. Remote sensing analysis with multi temporal data are used to identify land cover changes using supervised classification method and sediments growth using TSS spectral transformation method by Budiman to determined sediment growth. The result indicates dry land farming became the largest land cover in 1990, dry land farming growth in 2000, it's shrinks and mixed garden was growth with rubber trees and jati trees in 2010. And jati trees became dominant and changed into forest in 2015. The land covers change followed by TSS. From 1990 until 2010, TSS was stable on water body but growth in inlets and shrink in 2015.
