Evaluation of land resource balance using interpretation and object-based classification method (case study : BWP Lumajang,Lumajang district)

Abstract

Utilization of Natural Resources (SDA) is one of the bases used in implementing development in Indonesia. As the center of government and the economy, the Lumajang BWP has the highest population in Lumajang Regency. The annual growth of the Lumajang BWP population results in significant land changes. Calculation of land resources at BWP Lumajang is needed to determine the amount of land reserves and utilization in the area. This research was carried out to compile Lumajang BWP Land Resource Balance (NSDL) in Lumajang Regency using the on screen digitization (interpretation) method and image segmentation as object-based classification method. The results of this study are at a higher level of accuracy, the digitizing on screen method is 94.521%, for the image segmentation method it is 89.041%. In both methods, the land cover which has the largest decrease in area is irrigated rice fields and the largest increase is plantations.
