FUZZY MULTI-CRITERIA DECISION MAKING TO CLASSIFY LAND CAPABILITY AND SUITABILITY

Abstract

The land capability and suitability classification is a difficult thing to do. The problem formulated in this study is how to use fuzzy multi-criteria decision making to determine the classification of land suitability and suitability. In fuzzy logic shows the extent to which the value is true and the extent to which the value is false. Multi-Criteria Decision Making is a method of decision making to determine the best alternative based on certain criteria. The purpose of this study is to create a system that can facilitate the classification of land suitability and suitability by using fuzzy multi-criteria decision making. This research was conducted with three stages, namely: 1. The problem representation stage (including determining decision objectives, identifying alternatives, identifying criteria, and establishing a decision hierarchy structure), 2. Evaluating the fuzzy set of alternative decisions (including establishing linguistic variables) and membership functions, determine branches for each criterion, and calculate the fuzzy suitability index for each alternative), 3. Defuzzy stage to find an optimal alternative value. The expected output or outcome at the end of this research is the creation of a system of land capability and suitability classification using fuzzy multi-criteria decision making.
