Designing automatic midges for rice plants, in addition to trapping and repelling insect pests, can alsokill pests that always interfere with the growth of rice plants automatically based on microcontrollers. In thisdesign, PIR, ultrasonic sensors, and ESP32 are used as control systems. Ultrasonic sensors are used to emitultrasonic waves as a pest disruptor that wants to get close to rice plants. The PIR sensor itself is set to detectpests approaching plants and then react to the ultrasonic sensor to emit waves to disturb pests that perch on riceplants. The PIR sensor will work by capturing the thermal energy possessed by insect pests in front of the sensor. This is where the Arduino plays a role as a controller, which will carry out the execution. The use of this electric racket module is to give a sting to pests if the pests caught directly perch on the wire surrounding the lamp, where the wire has been supplied with a high electrical voltage even with a small electrical voltage input. In addition, the use of the module here is useful for killing pests that perch on traps if pests are not disturbed by waves emitted by ultrasonic sensors. The test results show that the performance of the designed system can function properly. The designed system can detect objects in the form of insect pests and can accurately display data to the 16x2 LCD.
