Engineering of Automatically Controlled Energy Aeration Systems for Fisheries Cultivation Pools

Fish need oxygen for metabolic processes, especially cultured fish. The high amount of dissolved oxygen (DO) in the water greatly affects the quality of life of the fish. A good aquaculture pond is a pond that uses an aerator machine, because the dissolved oxygen content will fulfill the life of all fish. The purpose of this research is to design an automatic controlled aeration device system and utilize solar panel technology as an energy source. This system uses a monitor feature for controlled oxygen levels using a DO sensor, the results of the monitoring are then displayed on the LCD. The data will be processed to make a decision, whether the aerator engine is on or off. The aerator engine activity is continuously controlled by a device connected to a sensor. The sensor will measure real-time dissolved oxygen levels and display it on the LCD. The test steps carried out on this tool are the automation response system test and power resistance test based on the load of the electronic circuit.  In the automatic system setting, when the DO value exceeds 6.86 mg / L, the aerator engine will shut down, then restart when the DO level is below 5.20 mg / L. Solar Panel electrical devices with a capacity of 10 WP, 10 A controllers and a 12 V, 7 Ah battery, are sufficient for the energy needs of electronic circuit loads. System testing shows that the system is functioning properly as intended.
