The Agroecological Zone using Fuzzy Logic for Land Suitability and Regional Sustainable Food Insecurity in Boyolali, Central of Java Indonesia

This study is aimed to develop agroecological zone model (AEZ) integrated with the evaluation of land suitability in order to attain the food tenacity in Boyolali County, Central Java, Indonesia. This model is established through five steps. First, it is stocktaking and identifying biophysical land characteristic. The second step is compiling map of suitability of land commodities. The third is compiling the indicator of food vulnerability. The fourth step is classifying variable with fuzzy logic and the last is generating map based on the selected variable. Fuzzy method was chosen because most research data contain uncertainty value. Fuzzy Inference Systems (FIS) concept enables to stipulate the suitability of land to be used by a particular type of plant, inhibiting factor and managerial advice that can be applied to overcome the presence of inhibiting factor, and also the appropriate location for a particular plant species. The findings of this study show some benefits that can be used for 1) compiling the indicator and detail map (1:50.000) of agroecological zone integrated with the suitability of commodities and the character of land (soil and climate) for agricultural cultivation, 2) compiling the appropriate sustainable land management, 3) compiling the indicator and detail map (1:50.000) of food vulnerability at the district level by a certain periodicity.
