Abstract

Corn demand in Indonesia is quite high, this commodity is useful as food, animal feed ingredients, and as industrial raw materials. The main problem in corn farm-ing is not enough production to meet the demand as staple foods and industry. It is necessary to increase the amount of corn production to meet demand as well as to increase farmers income and profits. Therefore, in this research we propose to develop a simulation model and scenario to increase farmers income through land productivity improvement. As a method use for model development, we utilize system dynamics framework based on consideration that system dynamics is a scientific framework for addressing complex and nonlinear feedback systems. System dynamics can use both qualitative and quantitative techniques such as computer simulations. It also facilitates the adoption of nonlinear mental models so that they can search and describe the feedback process of problem dynamics. In particular, system dynamics has proven useful in overcoming agricultural problems. Simulation results show that increasing farmers’ income can be done through increasing land productivity. With the increase in land productivity, corn production will increase, so that the income of corn farmers will also increase. In-creased productivity can be done by carrying out structural and non-structural ap-proaches. Structural approach can be carried out through rehabilitation of water-sheds and irrigation networks. Meanwhile non-structural approach can be carried out through the application of new technologies, strict land conversion rules, dy-namic planting calendars, dissemination of climate information, and the develop-ment of climate field schools.
