Abstract

Flooding is a natural disasters phenomenon that often occurs in big cities inIndonesia, one of them is Jakarta. The Consequences of the floods in Jakarta are lowlandmorphology, high rainfall, large surface flow (run-off), river gradient or drainagegradient is very gentle, tidal influence and siltation of rivers around estuary. Jakarta is apart of the Ciliwung River downstream part, with a low situation of Jakarta makes therole of the Ciliwung upstream part become very important. It is connected with aconsequence of the flood runoff that can not be optimally absorbed by the soil, due tochanges in land use are not in accordance with their designation as a protected areas. The aims of this study to determine the condition of the Ciliwung upstream partsuch as changes of land use, condition of morphology and its effect on the volume offlooding in Jakarta. After knowing the changes and morphology that exist in the areathrough satellite imagery, it can be planned arrangement of space that affect thedischarge of water flows into upstream part. This study is geographically located in 10604940" - 10700015" East Longitudeand 603815" - 604605" South Latitute. Administratively, Ciliwung upstream part covers30 villages in Bogor Regency there are 2 villages (Sukaraja Subdistrict), 7 villages(Ciawi Subdistrict), 10 villages (Cisarua Subdistrict) , 11 villages (MegamendungSubdistrict) and 1 village in the East Bogor Subdistrict. Ciliwung upstream partwatershed area are 14 860 ha. The method of this study by approach analysis of landforms and land cover. Themain data used are Landsat - 7 ETM +, geological map scale of 1 : 100,000 and theearth map scale of 1 : 25,000. In addition, for an extra analysis of geological conditions,also used the image processing results that is Digital Elevation Model. The results usedfor the basis of land use planning that expected to be one solution to reduction of rainfallthat disembogue into the Bay of Jakarta. The analysis results of Landsat satellite imagery with multi-temporal from time totime there are visible changes in lines vegetation area become more bit and pushed by thedevelopment in various sectors. With the land use planning on the Ciliwung upstreampart, the government is expected to objectify, so the discharge of run-off flowing intoJakarta is reduced.
