Increasing the population of the population increased demand for agricultural production, so this has an impact on reducing the use of agricultural land. Identification of land suitability is important so that there is an evaluation of land use to increase land productivity now and in the future. the purpose of this study is to evaluate the suitability of agriculture land to increase the production of paddy harvest on each paddy field with physical constraints. therefore, that it can help the stakeholder of agriculture land to take sustainable strategic decision making. Therefore, dynamic system modeling is applied to analyze the level of land suitability for paddy based on plant requirements, quality and land characteristics. This study can be used as a condition forecast that develops a system dynamics model to learn about future patterns of change in land use management that can support multi-purpose analysis of the objectives for optimal agricultural productivity concerning food security.
