Abstract

Land conversion or land cover cange is a change in the function of part or all of a land area from its original function (according to plan) to another function that causes negative impacts (problems) on the environment and the potential of the land itself. The research aims to analyze changes in land cover over a period of ten years with Landsat 8 imagery in 2013 and 2022 and to analyze changes in land cover in the Toili sub-basin, Banggai Regency. This study uses guided image analysis (supervised). Land cover classes in the Toili sub-watershed are divided into 9 (nine) land cover classes, namely, secondary dryland forest, settlements, plantations, dryland agriculture, paddy fields, shrubs, open land, bodies of water, and clouds. From the test of accuracy or precision of the results of loss of satellite imagery with the guided classification method (Supervised) has an accuracy level of 88.54%. The results of the analysis show that the largest increase in area is in the plantation class while the largest decrease in area is in the dry land farming class, this is the impact of activities carried out by the local community.

Abstract

Land conversion is a change in the function of a part or whole land area of its original function (as planned) into another function that becomes a negative impact (problem) on the environment and potential land itself. The study aims to analyze changes in land cover over five years with the image of Landsats 8 of 2016 and 2021 as well as analyze the factors of the cause of changes in land cover in the Limited Production Forest Area in Kulawi Subdistrict. The study used guided image analysis (supervised) and binary logistics regression analysis. The formation of spatial models of forest cover changes in the Kulawi Subdistrict Limited Production Forest Area using 5 modifier factors consisting of accessibility aspects i.e., settlement, population density, river, slope, road. Logit (p)=-0.24087+0.04249(x1)+0.2815(x2)-0.42492(x3)-0,.0480(x4)+0.04010(x5). The results of binary logistic regression analysis showed goodness of fit value of 5471996.86 chi-square values of 60287.17 and pseudo r2 of 0.30 greater than 0.2, indicating the model is worth using. Based on the results of binary logistics regression analysis, it is known that distance from roads, distance from settlement and population density are influential to changes in forest land cover.
