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.
