Abstract. The problems faced in organic rice farming is decreasing quality and fertility of land caused by the use of non-organic fertilizers or pesticides and also by climate change. This study aims to determine the environmental efficiency of semi-organic rice farming. The sampling method was purposively carried out consisting of 115 farmers from four farmer groups in Bantul Regency and had implemented semi-organic rice farming. The technical analysis used was Stochastic Frontier Translog Analysis with one input variable namely N fertilizer which was thought to be an input that could decrease environmental quality (detrimental environment input). The results showed that the coefficient value used to analyze the environmental efficiency from the Stochastic Frontier Analysis Translog is the coefficient value that interacts with N fertilizer. The environmental efficiency of semi-organic rice farming is still very low, ranging from 0.1434 to 0.6541 with an average of 0.40. This efficiency value shows that semi-
organic rice production will survive or even increase by reducing 60% from the use of N fertilizer. Environmental efficiency is influenced by the use of factors of production which are detrimental to the environment, climate change (temperature changes) and water resources management.
