Title: Spatial Analysis for Crop Land Suitability Evaluation: A Case Study of Potatoes Cultivation in Wonosobo, Indonesia
Abstract: At present, the potatoes cultivation strategy is still based on farmers preferences. They plant on their land without seeing the crop land suitability. This causes a low productivity of 16.99 tons/ha and the production target is not achieved, only 85.93%. The objectives of this study was to provide recommendations for optimizing suitable crop land using spatial analysis with overlay techniques. The contribution of this study was the combination of 5 physical factors in spatial analysis with overlay techniques to evaluate the crop land suitability value. We refer to Regulation Agriculture Minister of Republic of Indonesia No. 07/Permentan/OT.140/2/2012 with development based on overlay maps land ability, land suitability, regional potential and land for sustainable food agriculture. To measure the location suitability, we used five physical controls in spatial analysis of crop land suitability, namely altitude, soil texture, slope percentage, rainfall and temperature. We obtained 16 grids on all crop land units and we determined the samples were 16 points in Wonosobo, Indonesia. We used intervals of 3.75 and 4 classes to analyzed crop land suitability. By using overlay techniques, the results showed that the average has suitability for the crop land in good condition, with a few inhibiting factors that is equal to 67.21% spread in samples 3, 4, 5, 6, 7, 9, 11, 12, 13, and 14. To support sustainable food agriculture, we recommend cropping focus in Kejajar (sample number 1) which has the most suitable land suitability value for potato cultivation in Wonosobo. For further research, this method can be used to calculate the Land Potential Index using spatial analysis and remote sensing.
