The best paddy rice growth occurred in a depth of 2-25 cm stagnant water. Meanwhile, at this time condition
of water resources is increasingly limited so that it is necessary to find a method to overcome the existing problem. It

One of the technologies that can be applied is the approach of System Organic-Based on Controlled Aerobic Rice Intensification (SOBARI).
SOBARI is a holistic system of rice production based on integrated local input (straw compost, bio fertilizers,
