Summary: Various pesticides have been used to protect plants from various pests that produce significant damage. However, employing pesticides has several drawbacks, including the risk of its compounds harming plants, animals, and humans. The researchers came up with the idea of developing an ecologically sound gadget that may assist to protect crops from pests without damaging the crops, animals, or humans. The creation of an ultrasonic sound wave pest repellant is a significant contribution to farmers’ crop pest management activities. The device consists of eight ultrasonic sensors that may produce ultrasonic sound waves up to 40 kHz to disrupt the target insect. The device is also powered by a solar panel, which can charge at 1 volt per hour and discharge at 0.5 volts every three hours, allowing it to work for 24 hours. A solar panel charging and discharging test was conducted by the researchers to verify the supply’s capacity. Both tests took different amounts of time, but the results of the discharging test, which ranged from 10 to 11 volts, had steady remarks. On the other hand, the charging test also had positive remarks despite taking two different amounts of time to charge. Since the weather varies frequently and could destroy the device, the researchers also had the notion to utilize acrylic glass to protect it. Additionally, steel angle bar was utilized to support the project's base. A survey of the device’s functionality was done to evaluate its performance. A total of 32 people examined the device: 28 rice farmers, 2 engineers, and 2 college professors. The machine has an overall grade of 4.59, which corresponds to Excellent in descriptive terms.

Various pesticides have been used to protect plants from various pests that produce
significant damage. However, employing pesticides has several drawbacks, including the
risk of its compounds harming plants, animals, and humans. The researchers came up with
the idea of developing an ecologically sound gadget that may assist to protect crops from
pests without damaging the crops, animals, or humans. The creation of an ultrasonic sound
wave pest repellant is a significant contribution to farmers’ crop pest management
activities. The device consists of eight ultrasonic sensors that may produce ultrasonic sound
waves up to 40 kHz to disrupt the target insect. The device is also powered by a solar panel,
which can charge at 1 volt per hour and discharge at 0.5 volts every three hours, allowing
it to work for 24 hours. A solar panel charging and discharging test was conducted by the
researchers to verify the supply’s capacity. Both tests took different amounts of time, but
the results of the discharging test, which ranged from 10 to 11 volts, had steady remarks.
On the other hand, the charging test also had positive remarks despite taking two different
amounts of time to charge. Since the weather varies frequently and could destroy the
device, the researchers also had the notion to utilize acrylic glass to protect it. Additionally,
steel angle bar was utilized to support the project's base. A survey of the device’s
functionality was done to evaluate its performance. A total of 32 people examined the
device: 28 rice farmers, 2 engineers, and 2 college professors. The machine has an overall
grade of 4.59, which corresponds to Excellent in descriptive terms.
