Assessment of Land Suitability Evaluation for Plantation Crops Using AHP-GIS Integration in the Wonosalam Forest Area, East Java

Abstract

Plantation land expansion in forest areas has been a problem for some time as an effort to meet rising food demands, so land suitability measures are required. The development of the Analythical Hierarchy Process (AHP) and Geographic Information System (GIS) combination has been found to be effective in determining land suitability, but still rarely to determining plantation crops in forest areas. The study's goal was to integrate AHP and GIS methods to evaluate the land suitability class for plantation crops in the Wonosalam forest area. The findings revealed that the land suitability class assessment obtained S3 results, or results that were slightly in accordance with the erosion hazard constraint, to potentially S2 results, or results that were quite in accordance with many constraints such as retention factors, nutrients, erosion hazard, and land preparation. Furthermore, the expert decision-making hierarchy concluded that topography, climate, soil physical properties, and nutrient retention can consistently influence the direction of land suitability assessment policies for durian, clove, and coffee species. Rainfall, altitude, land preparation, and c-organic content are all important priority parameters in determining land suitability for durian plants. In contrast to cloves, temperature, surface rock, erosion, and pH are known to be important factors in determining land suitability. Experts also consider humidity, altitude, land preparation, and C-Organic as a land suitability assessment for the different types of coffee plants in the Wonosalam Forest Area.
