Abstract
Land suitability evaluation has an important role in determining the environmental boundaries of sustainable land resource management. The purpose of this study is to evaluate the suitability of land use in rice cultivation in Magelang, Indonesia. Environmental factors such as rainfall, drainage, depth, pH, organic matter content, slopes, and erosion level are used as criteria compared to 5 alternative lands (Sawangan, Mangunsari, Tirtosari, Podosoko, and Kapuhan). The ELECTRE method as one of the multi-criteria decision-making methods chosen to solve the concept ambiguity problem in land suitability assessment. The result shows that the application of this method is quite effective for decision making so that alternatives are obtained that have the highest land use suitability compared to other alternatives for environmentally friendly rice cultivation. Finally, a decision support system with a web-based ELECTRE Method is presented to facilitate decision-makers in obtaining more accurate land suitability information.
Highlights
Sustainable land resources are an important part of realizing sustainable agriculture
There are several previous studies that use ELECTRE methods such as land suitability evaluation in wheat cultivation [11], evaluation of solar panel installation locations [12], identification of wind turbine installation locations [13], selection of the best alternatives for water resource allocation planning [14], decision making analysis for renewable energy selection [15], the ELECTRE method is applied to calculate the strength of outranking relationships of various power plants [16], and analysis of land-use suitability for rural tourism [8]
Seven criteria (Table 2) are codified into C1-C7 and the alternative used is in the form of agricultural fields for rice cultivation with a total of 5 alternatives consisting of Sawangan, Mangunsari, Tirtosari, Podosoko, and Kapuhan which are codified into A1-A8
Summary
Sustainable land resources are an important part of realizing sustainable agriculture. There are several previous studies that use ELECTRE methods such as land suitability evaluation in wheat cultivation [11], evaluation of solar panel installation locations [12], identification of wind turbine installation locations [13], selection of the best alternatives for water resource allocation planning [14], decision making analysis for renewable energy selection [15], the ELECTRE method is applied to calculate the strength of outranking relationships of various power plants [16], and analysis of land-use suitability for rural tourism [8]. Criteria that is used in this study are the number of wet months, drainage, soil depth, average pH, c-organic, slope, and erosion level This session will explain the decision support system, land suitability evaluation, and the ELECTRE Method. This session will explain how to use the methodology used in this study
