Abstract
Abstract – Rice is one of the staple foods of the
Indonesian population and has an important role in the
formation of the Gross Domestic Product (GDP).
However, this role has not been able to run well because
many pests attack and cause crop failure, one of which is
sparrow pests. For this reason, a study was conducted
using ultrasonic sound to disturb the pests so that they
do not land and leave the rice plant. The ultrasonic sound
is emitted when the bird approaches and breaks the
electronic net of the laser beam spread over the rice
plant. This prototype was built using the NodeMCU
ESP32 microcontroller as the controller and system. And
telegram is used as a supporting application to give on/off
commands and battery percentage detectors to facilitate
use. According to the the research, the prototype
functions properly and the disturbed by ultrasonic sound
with frequencies ranging from 0 - 22,000 Hz and sound
pressure levels between 31.6 - 93.2 decibels.
Keywords: ESP32, Laser, Rice, Sparrows, Ultrasonic
