The study aims to analyze the level of agricultural sector efficiency and agricultural extension performance in Central Java. A stochastic production function is used to estimate the efficiency. Meanwhile, descriptive statistics was employed to assess the performance of agricultural extension. The result reveals that agricultural sectors; corn, rice, and vegetable, are considered to be less efficient. However, there is an opportunity to optimize the agricultural products by using production factors based only on the needs. Moreover, it is found that the respondents' perception of the agricultural extension performance is less optimum and the number of extension is not yet ideal.
