Abstract. One of the climate change phenomenon is uncertainty weather condition. This study aims to understand the technical efficiency of rice farm in Yogyakarta included the factors that influence them in uncertainty weather condition. We survey for sampling has been done in Sleman and Bantul Regency based on about 8 of water irrigation resources and about 25 locations of water irrigation area. The sampling method is simple random sampling to take 125 samples. Cobb Douglas translog frontier production function model has been used to analyze the factors that influence rice production and technical efficiency. The result of the production function shows that the factors that influence the rice production are land, labour, organic fertilizer, N fertilizer, irrigation pollution, irrigation type, season and location. The rice farm has not efficient. The study result gives the implication that the rice farm efficiency for sustainable agriculture, it needs using optimal input, peasant skill encouragement, and infrastructure development of irrigation.
