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