Food is one of the basic human needs. Government has set strategic commodity targets, one of which is corn and chicken. Corn is an important agricultural commodity for humans and livestock. There is a challenge where the increase in corn production is going slow so far. As a result, the speed of increasing demand for corn cannot be pursued to increase production. This also has an impact on chicken farmers which have a mutualism symbiotic with corn farmers. The selling price of corn and the right price of fodder will produce the right price of chicken and chicken eggs. This condition will have an impact to the welfare of corn and chicken farmers. This study aims to project the adequacy of corn both for humans and fodder by concerning the welfare of corn farmers and chicken farmers with parameters of corn and fodder prices. An approach with a dynamic system simulation is carried out to achieve a balance between the welfare of corn farmers and chicken farmers to be able to maintain their future existence based on corn prices and fodder prices. This approach is used because of the ability of this model to solve complex system behaviour between variables.
