Abstract
   Maize (Zea mays) is one of the strategic commodities in Indonesia's economy, because it is a second food-producing carbohydrate after rice Corn self-sufficiency program (Program Swa-sembada Jagung) launched by the government, requires good cooperation between the farmers and the government. Corn demand was increased continually, in line with the living standards of the local economy and the progress of the animal feed industry. Human resources, natural resources, land availability and potential yield and technology, have roll in increasing the production number. The aims of this experiment were to analyze the influence of production factors to the corn production and also to analyze the efficiency usage in corn farm enterprises at Serang District, Banten Province. Sampling method was done by stratified random sampling method, with total samples of 61 corn farmers. Results indicated, that simultaneous effect of land area (X-1), seeds (X-2), urea (X-3), pesticides (X-4), NPK - nitrogen, phosphor and potassium (X-5), the use of manure (X-6) and labor (X-7) factors, significantly affected the corn production. Partially, land area (X-1), seeds (X-2), urea (X-3), NPK (X-5), and the use of manure (X-6) factors, significantly affect the corn production. Economically, the land use (X-1), seeds (X-2), and pesticides (X-4) factors, shows inefficient yet, whereas for urea (X-3), NPK (X-5), the use of manure (X-6) and labor (X-7) as the production factor, shows not efficient.

Key words: production factors, Cobb-Douglas, economic efficiency, corn farming
