The purpose of this study was to determine the oxygen transfer rate efficiency of paddle wheel aerators in intensive shrimp farming. This study was conducted with the causal ex-pose facto concept by comparing the performance of paddle wheel aerator. The results showed that water quality in Pond 1 (1 HP) and Pond 2 (2 HP) only brightness which do not comply with water quality standards. The oxygen transfer rate paddle wheel aerator was 1 HP of 3.20 (2.82-3.65) mgO2/hours and for 2 HP of 2.12 (1.68-2.89) mgO2/hours. The dissolved oxygen in Pond 1 (1 HP) was 5.25 mg/L and Pond 2 (2 HP) was 5.63 mg/L. The shrimp growth rate in pond 1 is 1.95 (0.01-4.0 gr/day) and pond 2 is 1.25 (0.01-2.55 gr/day). Dissolved oxygen in pond 1 (1 HP) ranged from 4.15-7.26 mg/L and pond 2 (2 HP) ranged from 4.03-8.31 mg/L. Dynamic modeling results show a description the energy input to paddle wheel aerator will gradually decrease from 2 kW to 0.25 kW. The results of this study concluded that the use of a 1 HP paddle wheel aerator has a better oxygen transfer rate and shrimp pond performance than using a 2 HP paddle wheel aerator.
