Abstract

Land and forest fire is a condition where the land and forest are hit by flame, causing land and forest destruction, economic losses, and environmental value. In the dry season, some of the regions in Indonesia often hit by flame. One example is a fire that occurred in the area of Mountain Bromo on October, 20th to 23rd 2014. These fires resulted in approximately 1.487 Ha of savanna forest got burned. Burned area can be identified by using remote sensing data, such as Landsat-8 and MODIS imagery. The method of identification used is the NDVI (Normalized Difference Vegetation Index) that utilizes near-infrared band and red band. Burned area is classified based on the value of the three threshold models. The use of multiple threshold models is done with the purpose of seeking the greatest accuracy value. Based on the results of burned area identification, obtained the greatest accuracy values of Landsat-8 is 48.394% from the   - 1  models and the wide of burned area is 1.354,5 Ha. While the greatest accuracy values of MODIS is 57,089% from the    models and the wide of burned area is 1.005,209 Ha.

Abstract

Village map is a basic thematic map that contains elements and information on boundaries, transportation infrastructure, toponyms, waters, infrastructure, land cover and land use that are presented in several map forms. The diversity of village map types in Indonesia is one of the reasons for the Geospatial Information Agency to make a standardization policy of village mapping as a national reference. Procurement of village maps is needed to accelerate the process of village and rural development by utilizing spatial data. The final result of this study is a village map consisting of an image map, a map of land cover, and a map of infrastructure. The presentation of the Panyuran Sub-District map is adjusted to the map elements that must be displayed in accordance with BIG Decree No. 3 of 2016. The percentage of conformity of the presentation of image maps to the mandatory elements is 71.43%, 0% selected elements, and conditional elements 91.30%. Then the percentage of suitability of the presentation of the map of land cover to the mandatory elements is 71.43%, the optional element is 0%, and the conditional element is 88.89%. While the percentage of suitability of the presentation of infrastructure map is 75.00% mandatory element, 0% optional element, and 92.00% conditional element.
