DO (Dissolved Oxygen) needed in the shrimp ponds become important. Paddel wheel aerator using for mechanical aeration is the exact solution. Except practice, compact, paddle wheel aerator also get to answer DO needed. But the paddle wheel aerator operation cost is too expensive. The operation cost trough 80% from the total cost of electricity. 10 % for pump electricity and 10% again for the energy of processing commodity.<p> <br /> <br /> <br /> <br /> <br /> PT LAPI ITB and LMBSP ITB research for optimation the paddle wheel aerator. The goal is the paddle wheel operation cost will be reduce. Gear reducer is the part being optimation focused. From data and field condition, the re-design prosses produce the helical gear reducer.<p> <br /> <br /> <br /> <br /> <br /> The helical gear reducer test is focused to the mechanical effisiensi which affect to the cost of using energy. With calculate some of variable which effect the gear reducer performance, this test is take in the several gap of load condition and the quantity of load till maximum load. In the same case, this test metode also aplicate to standart gear reducer. The result is being compare one to the athers and the effisiensi of helical gear reducer higher than standart gear reducer. This superiority will be effected to the aother things, especially the operational cost.
