Abstract
Rice water productivity (RWP), a new concept in agricultural water management, is one of the keys to achieve food security in semiarid area like the West Timor region. Information regarding the value and growth of RWP over time is important. Therefore, this research aimed at the estimation of RWP, subsequently estimating the rice water total factor productivity (RWTFP) growth with efficiency change (EFC) and production technology change (TEC) of the West Timor region during the year 2000 - 2015. In doing so, we utilized secondary climate and crop balanced panel data and also applied stochastic frontier analysis (SFA) using the Cobb-Douglas (CD) and Transcendental Logarithmic (Translog (TRS)) production functions with four types of assumed efficiency distribution models to estimate the RWTFP growth. The results showed that due to the instability of rice production and rice consumptive water use inflicted the fluctuation of RWP with the average was 0.452 kg m-3. Both CD and TRS functions exhibited a constant EFC to all districts. CD functions showed a 3.964% improvement of TEC and RWTFP growth, but TRS showed 0.023% decrease of TEC and RWTFP growth. It is important to improve the TEC while maintaining the EFC to gain positive and sustainable RWTFP growth.
