Optimizing Water Use of Energy-Saving Water Dispensers Using A Bicycle

Abstract

This research aims to 1) design and develop an energy-saving water dispensers using a bicycle and 2) to find the efficiency of an energy-saving water dispensers using a bicycle. The results showed that calculation of the working rate of the water spreader to find performance and information. It was found that pumping water with a 1-inch water pump, using a bicycle to spin a 7-inch chainring, 3-inch free sprocket, 22-inch and a 7-inch with water pump mullay, the final speed was equal to 252 rounds/minute, the total rate is 0.119, pumping with a bicycle, the efficiency of the water dispenser, working in 1 minute can pump 42 liters of water. As for the water propeller pattern, it will help the water pressure to get a longer distance. The efficiency of the machine at a distance of 2 meters, when the timer is equal for 3 minutes, the water comes down to the water propeller. The amount of water that is obtained is 225 liters and the water comes down without a propeller 195 liters, which a downstream type with a water propeller will have more than 30 liters of water without a propeller. In terms of satisfaction, farmers who experimented with energy-saving water dispensers using bicycles in all four aspects had a high level of satisfaction with an average of 4.35 (87.00 percent).
