Rice Farming Technical Efficiency Using Certified Seeds in Indramayu Regency. Production inputs used in rice farming can affect crop yields. Yields can be increased through technical efficiency or production efficiency approaches. Technical efficiency is defined as an effort to increase the maximum output from the use of a certain number of inputs or technology. This study aims to analyze the technical efficiency and determinants of technical inefficiency in rice farming using certified seeds in Indramayu Regency. The data collected were in the form of production inputs and farmer characteristics from several farmers whose rice farming used certified seeds in Jatibarang, Bangodua, Widasari and Cikedung Districts with a total sample of 84 respondents. Technical efficiency and determinants of technical inefficiency were analyzed using the Stochastic Frontier Analysis (SFA) approach. The results of the analysis show that rice farming using certified seeds in Indramayu Regency is technically efficient with an average technical efficiency value of 0.93. Production inputs that affect technical efficiency include land, seeds, nitrogen nutrients, phosphate nutrients, potassium and pesticides. Land, seeds, phosphate and potassium nutrients significantly affect technical efficiency at the 1% real level, while nitrogen and pesticide nutrients have a significant effect on technical efficiency at the 5% real level. Variables that affect technical inefficiency include age and experience of farmers. Farmer’s age has an effect on technical inefficiency at the real level of 5%, while farmer’s experience has a significant effect on technical inefficiency at the real level of 10%. The conclusion is that rice farming using certified seeds in Indramayu Regency is technically efficient.
