Soybean is the third important food commodity, after rice and corn, with the increasing trend of demand (8.74 percent/year). Therefore, the imported soybean is maintained at a high level (1.2 million ton in 2008). The research on efficiency of soybean farm production system was conducted in three districts in South Sulawesi Province, namely Bone, Soppeng and Wajo. The locations were selected using a purposive sampling technique considering that those three areas are the soybean producing centers. This research uses a Cobb-Douglas Production Function applying an Ordinary Least Square (OLS) method and Profit derived from Cobb-Douglas Production Function with a Unit Output Price Cobb-Douglas Profit Function (UOP-CDFF) technique. The result shows that the technical factors influencing the increase soybean production are the farmers' experience, family labor, urea, KCl, organic fertilizer, ownership dummy (profit sharing), the dummy of soybeans variety (high variety), dummy of planting distance (40 cm x 15 cm and 40 cm x 10 cm), and also the land type of dummy. Amount of the three production input types (fertilizers) could be increased to improve the production. Moreover, positive factors influencing the TER (Technical Efficiency Rating) in soybean farming are land size, farmers' age, educational background, and farmers' experience. Efficiency could still be achieved by decreasing the use of part time labor (non family member) to maximize the income, and by reducing the use of soybean seeds, part time labor and land size to increase the profit.
