System Dinamic Model (SDM) is an effective approach model in solving problem of complex system. Although there have been development in expanding System Dynamic to include spatial system model, most aplication have been restricted to simulate many chances and get the wise argumentated policy. This study is conducted to answer increasing demands of beef in Daerah Istimewa Yogyakarta (DIY), Indonesia by looking into the availability of land to be used as feedlot. The backgroud of the study is initiated after looking a gap between rising demand of beef and its supply. Demands of beef in Indonesia rise rapidly by 4 %/yr but the production growth by only in 2.38 %/yr (Indonesia Statistical Data Beaurea, 2016). In DIY the condition is similar. There is a gap between rising demands of beef and its supply too. This research focus in to what extend the availability of land can cover dinamic change condition. We used Spatial System Dynamic to close the objective of the study. We incorporate a partial dynamic System Approach especially a Causal Loop Model (CLD) to achieve the goal of the reseach. This study is result generally suggests that DIY Area, there is suffice to meet the increasing beef demands. A number of policy might be taken to solve the problem. Among them is to properly address land usage. In future time, we might to keep land wise and also we must handle of agriculture land to other purpose seriously.
