Abstract

Background: Apple has long been known as a typical product in Malang. The sustainability of apple production is threatened, because the area of land and productivity of apples are decreasing, and the cost of producing apples is increasing. As a result, apple farming income has declined Aims: to analyze the sustainability of apple production in the future, simulate dynamic models of several scenarios, and provide alternative policies for decision makers Materials and Methods: The method used is modeling with a dynamic system approach followed by a simulation based on a predetermined scenario. Dynamic system modeling is done by means of a causal loop diagram (loops) that produces dynamic model structures and dynamic system behavior. The main data of the study are secondary data, including apple planting data, apple production and productivity. Primary data as a supporter is financial data on apple cultivation in Poncokusumo District, Malang Regency. The research data was analyzed using a dynamic system using Vensim software Results: The results showed that the sustainability of apple production consisted of 3 sub-models, namely sub-models; land ownership, productivity and production costs. In each sub model there is an input variable which functions to input data in each scenario that is made according to real conditions. This dynamic system model has five scenarios, namely (1) without policy; (2) policies for utilizing land resources; (3) productivity improvement policies; (4) policies for utilizing land resources and increasing productivity; (5) policies for substituting chemical pesticides. Conclusion: This dynamic system model has five scenarios, namely (1) without policy; (2) policies for utilizing land resources; (3) productivity improvement policies; (4) policies for utilizing land resources and increasing productivity; (5) policies for substituting chemical pesticides
