Evaluation of land suitability for coffee plants based on fuzzy logic in Enrekang district

Abstract

Ecological perspective is important in agriculture, because sustainable agriculture is based on cultivation practices that do not deviate from natural systems. In an ecological perspective, agriculture is based on differences in climate, soil properties, soil morphology that requires different management and processing of agriculture between regions. Research was conducted in Enrekang district with reference to 18 Land systems. This study aimed to assess the land suitability for coffee plants based on geographic information systems using a fuzzy logic approach. Primary data as evaluation criteria were divided into three main components; for potential land erosion, potential flooding and soil profile. Land cover was considered as well. In fuzzy analysis, the value of land attributes was converted to sustainable values (ranging from 0 to 1.0) according the class limits determined based on experience and standard conventional. There was distribution of land suitability for coffee plants in Enrekang district. 65% of the area had the potential to develop coffee plants. The main limiting factor in the development of coffee plants in the study area was the erosion potential, especially the slope.
