Aplikasi GIS dan AHP Dalam Kesesuaian Kawasan Penanaman Anggur: Kajian Kes di Negeri Perlis

The site suitability for fruit crops is one of initiatives to improve the fruits production. Six variables were involved in this study there was maximum temperature, annual rainfall, relative humidity, soil series, topography and land use. Spatial analysis was done on suitability variables by using Geographic Information Systems (GIS). An Inverse Distance Weight (IDW) technique was applied to determine of sample values for the all areas in Perlis. The raster calculation and reclassification was showed the suitable and unsuitable area for grapes cultivation has represented by scale 1 and 0. Results showed that an almost area was suitable for grapes cultivation in Perlis. An Analytical Hierarchy Process (AHP) was applied to support the results of weight value for the each variable. Results showed that grapes cultivation has an inclination with the highest weighted value for topography which is 0.28 (28%). Analysis based on AHP showed that most of territorial division is suitable for grapes cultivation. The area were represented by scale 1 has a potential for grapes cultivation. This study was showed that GIS and AHP techniques in grapes cultivation has a new phase in evaluation and determination process by decision makers. The risk of cultivation damage has been decreasing by involved all site suitability variables.
