Komparasi Metode Fuzzy Logic dengan Weigthed Overlay dalam Analisis Kesesuaian Lahan untuk Tanaman Gaharu di Kecamatan Koto VII Kabupaten Sijunjung

Agarwood plants are non-timber forest products (NTFPs) which are used as a plant with high economic value by using the forest as a place to grow. Koto VII sub-district is one of the areas that has customary forests or nagari forests where full management rights are given to the community. Research objectives (1). To determine and map the suitability of agarwood plantation land in Koto VII District, Sijunjung Regency using the Fuzzy Logic method. (2). To determine and map the suitability of agarwood plantation land in Koto VII District, Sijunjung Regency using the Weighted Overlay method. (3). To find out an accurate comparison of land suitability levels for agarwood plants in Koto VII District, Sijunjung Regency using the Fuzzy Logic method and the Weighted Overlay method. Descriptive quantitative research method with data presented through tables and maps, calculations referring to the results of analysis for land suitability and accuracy tests of both data analysis methods.This research uses quantitative research methods to analyze the suitability of agarwood plant land in Koto VII District. The results of this study are the suitability of land for agarwood plants using the fuzzy logic method with a very suitable class with an area of 9.899,49 Ha. Then the class is quite suitable with an area of 6.092,34 Ha and the class is not suitable with an area of 71.82 Ha. While the analysis of land suitability with the weighted overlay method is a fairly suitable class with an area of 7.761,64 Ha, then a very suitable class of 6.051,30 Ha and an unsuitable class of 2.250,80 Ha. For the accuracy test of the two methods used as land suitability analysis, it is known that the level of accuracy of data analysis with the fuzzy logic method field sample is 86% while the weighted overlay method is 83%, this shows that the more accurate analysis results with field samples are fuzzy logic methods with a difference of 3% higher accuracy results than weighted overlay.
