The Model of Land Cover Change into Settlement Area and Tin Mining and its Affecting Factors in Belitung Island, Indonesia

Abstract

The purpose of this research is to formulate model of land cover change into settlement area and tin mining area and to formulate factors influencing the land cover change in Belitung Island during 1995-2015 period. Formulating model of land cover change into settlement and tin mining area in Belitung Island during 1995-2015 period is done by using the interpretation of Landsat Image 5+TM year 1995 and Landsat Image 7+ETM year 2015 with GIS-ENVI 5.1 and GIS-ERDAS 9.1 using tools analysis supervised classification. The analysis of land cover change (ha) during 1995-2015 period (20 years) is done by using converted GIS-ENVI 5.1 with GIS-ERDAS 9.1 of tools GIS Analysis Matrix. The factors affecting land cover change into settlement and tin mining area in Belitung Island during 1995-2015 period are found out by formulating population social model. The data tabulation of land cover change data analysis (ha) are dependent variables which are then associated with independent variables as the representative of population and social characteristics analyzed with SPSS 15. The method is arranged by using multiple regression analysis technique with forward stepwise regression method. The interpretation results of Landsat Image 5+TM year 1995 and Landsat Image 7+ETM year 2015 show that the change of forest cover into settlement area is 59,840.07 ha, tin mined land/shrubs land into settlement area is 4,511.04 ha, the forest into tin mining area active is 46,122.44 ha, tin mined land/shrubs into active tin mining lands is 352.13 ha, and water/lake former tin mine land into active tin mining lands is 18,417.03 ha. The change of land cover into settlement area in Belitung Island during 1995-2015 period is consistently influenced by the factor of MINER_X₅ positively. On the other hand, change of land cover into tin mining area active is consistently affected by MF_X₂ and MINER_X₅ positively.
