Abstract

Land and forest fire are the natural disasters that often occur in Indonesian regions, especially Sumatera and Kalimantan. The disasters cause deep impacts to environments and human beings, so it is necessary to conduct mitigation. The research area took place in Central Kalimantan Province. The objective of the research is to applicate the MODIS remote sensing imagery for supporting the land and forest fire mitigation efforts, that is identifying the burned area. The analyzing is done by using methods of NDVI changes before and after land and forest burned periods in 2009 . The stages of the research consist of; fire hotspot frequency analyzing, NDVI changes calculation, threshold of NDVI changes establishing, and burned area estimation based on the threshold result. The results of the research show that the burned area in Central Kalimantan can be identified by using MODIS based on NDVI changes. The total numbers of burned area in 2009 are 122.900 hectares, most of them occured in Pulangpisau, Kapuas, Katingan and Kotawaringin District. The results are needed to be verified in the next further research based on the field survey and or by using the high resolution imageries such as Landsat, SPOT-2 or 4, ALOS, Ikonos or Quickbird. Key Words: MODIS, Burned Area, NDVI, Central Kalimantan

Abstract

Jakarta is the biggest city in Indonesia located in the north-western of Java Island and between 5º59’–6º00’S and 106º30’–107º00’E. The total area is approximately 661,52 km2, and the population is more than 9 million in 2008. The occurrence of many flood in Jakarta had caused loss in properties, environmental degradations, and warsen communities health. A spatial approach model is applied to understand the effects of flood to land use in the research area. Objectives of the research are : 1) to create the hazard assessment model and 2) to calculate the impact of flood to the land use area. The methods consist of neighbourhood operation application development in the form of raster pixel calculation, in this case are the Digital Elevation Model values, by using mathematic calculation formula to assign the inundated area. Land uses, either the inundated or others, are the result of imagery data interpretations. Results of the research show that the simulation model represent the condition in the field when flood happened maximum scenario for inundation area of 2,00 m will affect to about 5,10 Ha (regular settlements); 80,82 Ha (irregular settlements); 2,22 Ha (open areas); 5,09 Ha (business areas); 40,39 Ha (office areas) and 18,83 (roads). Key words: Ciliwung flood, DEM, Iteration spatial model, GIS, Remote sensing
