Design Tools for ControllingBrown Planthopper Pests Using Ultrasonic Waves

Abstract

The brown planthopper pest is a main pest of rice production in East Java and mostly Indonesia areas. The main controls of brown planthopper are mostly using chemical pesticides, which caused resistance on pest. Resistant varieties are the main choice for overcoming attacks of planthopper. However, resistant varieties had limitations because brown planthopper adapted to new biotypes. Conventional Integrated Pest Management (IPM) is reactive to pest attacks and often continues to rely on insecticides. One of the promising ecofriendly technologiesis ultrasonic waves. This study the aim was to design a planthopper pest control system in a room using the HC-SR04 ultrasonic sensor with a frequency of 40 KHz. The trial in the first stage was limited to testing the functionality to the system and testing the range of tools carried out to determine the area covered by the wave ultrasonic. The results of testofthe system are all system components are working properly. The ranges of the tools area maximum range is three meters in surrounding of the ultrasonic sensor.
