Fruit Fly Repellent Using SMS Gateway as A Monitoring System

Pests are one of the main obstacles for farmers that can cause a decrease in the amount of crop production. One of the pests that often disturb farmers, especially for chili farmers or other horticultural crops, is the fruit fly. This pest is very disturbing harvests because their numbers are increasing quite rapidly. This problem underlies the development of this pest repellent. The working principle of this tool is to repel fruit flies using ultrasonic waves without using pesticide drugs that can damage the environment if used continuously. This tool is designed using Arduino Uno as the main controller. Ultrasonic waves and generated and regulated using piezoelectric at a certain frequency as a fruit fly repellent. Then the tool is rotated using a servo motor to reach all corners of the land. For control and monitoring, this tool uses the GSM SIM800L version 2 module for sending short messages. From the results of the overall evaluation, this fruit fly repellent can work according to its function. This can be proven by testing when not using a fruit fly repellent, there are a lot of flies trapped in the bait bottle totaling 30, while when given a repellent, the flies trapped in the bait bottle are reduced to 15 with the information that the buzzer can emit sound, and servo motor moving condition, as well as GSM SIM800L, can send messages to the sender.
