The purpose of this research is to analyze the level of efficiency in the use of sorghum farming production factors and the factors that influence sorghum farming in Keyongan Village, Babat Sub-District, Lamongan Regency. This research uses the Snowball Sampling method with a total sample of 80 people. In the method of data analysis using descriptive and qualitative data analysis methods with production function analysis tools, Stochastic Frontier Analysis (SFA), and economic efficiency analysis. The results showed that the factors of seed production, organic fertilizers, and labor had a positive and significant effect on the production of sorghum farming, while Urea, NPK, foliar fertilizers, and pesticides had no significant effect. The results of the efficiency analysis obtained an average technical efficiency value of 0.982, which means that the use of production factors in the study area is quite efficient because the efficiency value is more than 0.8. Influencing factors of technical inefficiency negatively and significantly are the labor dependents and employment status. Meanwhile, the age and length of farming had no significant effect. The value of allocative efficiency in sorghum farming in the study area is 1.80, which means that the allocation of production factors is not price efficient. So it is necessary to add the factors of seed production, organic fertilizers and labor. The economic efficiency value of sorghum farming is 1.78 so that sorghum farming in the study area is not economically efficient.
