This research was conducted based on the idea that farmers of maize did not ever orient to apply the production factors at the optimum level on their farm. The research carried out in Kuta Makmur District North Aceh Regency Aceh Province. The purpose of this study was to determine the level of input application and to determine the optimum level of maize production factor to be applied in maize farming in Kuta Makmur District, North Aceh Regency. Cobb Douglas production function for maize that obtained by this research is as follow:
Y = 0.3253X10.263 X20.261X30.229X40.103X50.196X60.002eU
Where: size of land is X1, quantity of seed is X2, quantity of Urea is X3, quantity of SP-36 is X4, quantity of KCl is X5, and quantity of labor is X6. The effect of those input on the level of maize production simultaneously highly signifcant, it was showed by the high value of Fcalculated and R2, otherwise the effect of independent variable of inputs partially still signifcant for X1, X2 and X3, but for X4, X5 and X6 could not affect the level of maize production signifcantly. All level of inputs application are situated in reasonable region where the increasing of inputs less than 1% due to addition of input addition of input at 1%.Except labor and all the other application of inputs should be increased for the optimal reason. In addition to quantity of labor application specially should be reduced. The following are quantity of input should be applied in the related of optimization reason: Optimal size of land is 7.9 Ha, Seed 48.33 kg/Ha, Urea 402.80 kg/Ha, SP-36 284.60 kg/Ha, labor 39 mandays.
