The population increase in Indonesia is comparable to the increase in basic needs of the community. One of the staple foods of the Indonesian people is rice originating from rice plants. Disruption to the growth of rice plants can reduce the production of rice plants, which has an impact on the scarcity of rice in Indonesia. One of the obstacles to rice production is the attack of rat pests. Rat pest control is the biggest challenge for farmers in Lampung province, especially Pringsewu Regency. Rat pest attack can reduce rice production up to 80%.In this study, a control system was designed to reduce the population of rat pests in the rice fields. The working principle of this control system is to interfere with the hearing system of rat pests in the area of the tool range. This system used an ATMEGA 328 microcontroller equipped with Arduino Uno board. The installed actuator consisted of four ultrasonic tweeters while the sensor installed consisted of four passive infrared sensors (PIR) sensors. The Actuators and sensors were installed around the control system framework and a 50 Watt solar panel was installed to collect independent electrical energy. The control system actuator was able to reach 1200 m2, while the sensor was able to detect the presence of interference in the range of 78.53 m2. The maximum distance of the sensor with the interference source was 5 meters. The control system was able to recognize interference and turn on the actuator by 100%. The response of the control system to activate the actuator when the ratwas in the PIR sensor area was 0.12 seconds. The average time of the rat to shied away the bait to the effect of ultrasonic sound waves was 4 seconds. These results indicated that the control system was able to detect and disrupt rat pests while in the range of the control system.
