Research using Research and Development (Research and Development) which includes design, system requirement analysis, design, testing and system implementation. Research consists of three main subsystems, namely input, system and output. Sub-system consists of pH sensor, Ultrasonic and Flowmeter to manage the automation process in maintaining water quality in catfish pond contained in Arduino Uno microcontroller. The output subsystems are AC and DC motors for dewatering, filling and checking samples to be displayed on the LCD. \u0000Based on the results of the over all testing that has been done, it is known that the motor control device to maintain the pH of the water catfish pond using pH and ultrasonic sensor based Arduino Uno able to maintain the condition of catfish pond water in the conditions suitable for catfish habitat, that is with pH 6.5 - 8.
