Technical efficiency analysis of maize farming in Wajak District, Malang Regency with data envelopment analysis approach

Technical efficiency is becoming essential indicators in estimating agriculture productivity, The aims of this research are to estimate the technical efficiency level and analysis factors affecting the technical efficiency level of maize farmer. The research was conducted in Wajak Sub-District of Malang Regency in East Java, Indonesia. Primary data was collected from 110 maize farmers and analyzed by data envelopment analysis and Tobit regression model. The result of this study claimed that farmers in the research location are technically inefficient because of the technical efficiency level less than one. Furthermore, the result of Tobit regression shows that the farmers’ education level has a significant and positive effect on technical efficiency level. However, the family dependency and farmer group participation have a significant and negative effect on technical efficiency level. This finding can be concluded that farmers need to minimize the input usage to increase the technical efficiency level.
