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.
