Pemetaan Tingkat Kerawanan Pencurian Pohon Menggunakan Sistem Informasi Geografis di KPH Balapulang Perhutani Unit I

Abstract

KPH Balapulang forestry is one of the companies run by Perhutani Unit I Central Java. One forest disruption occurs in KPH Balapulang the tree theft. Theft of trees can also threaten the sustainability of forest management and function. Geographic Information Systems (GIS) can help forest management. With the ability to build GIS spatial model. The purpose of this study itself are: making maps theft of trees, identifying factors that influence the theft of trees, and create a map of their vulnerability to theft trees. Map of tree theft is divided into five classes, namely tree thefts: low, pretty, medium, high, and very high. The factors that affect the distance the tree thefts, residential distance, age classes, and class slopes. Spatial model obtained the degree of vulnerability maps obtained tree theft is divided into five, namely: low-prone, quite vulnerable, being vulnerable, high-prone, and very vulnerable. Test the accuracy of the model produced Kappa values of 78,45% accuracy using the reference year 2008 and amounted to 65,69% using the reference year 2011
