Abstract: Background and Objective: The agricultural sector has an important role in long-term economic development. The development of the agricultural sector aims to fulfill the needs of food and nutrition as well as to increase the community’s income and welfare. Soybean is a food source that produces vegetable protein. Its protein plays a role in improving people's nutrition. This study aims to: (1) Determine the level of technical efficiency of soybean farming, (2) Find out the factors that influence the production of soybean farming. Materials and Methods: This study was carried out from January to June, 2019 in Southeast Sulawesi Province, by selecting three districts as the main producers of soybeans. The sample as 186 farmers was selected based on the multistage cluster random sampling. The data analysis method used the Stochastic Frontier 4.1c production function and the linear function analysis of the Cobb Douglas. Results: The results showed that the average technical efficiency of soybean farming was 0.64 or 64%. In terms of the allocation of production factors, the area of land, seeds and fertilizers was positive and significantly effecting production factors of soybean farming. Conclusion: The results of the analysis and discussion showed that the average technical efficiency was 0.64 or 64%. The index means that soybean farming in Southeast Sulawesi Province had not been efficient. Factors that have a positive and significant effect on the production of soybean farming in Southeast Sulawesi Province are land area, seeds and fertilizer.
