Abstract :
A prototype system for monitoring and lifting garbage in the river has been carried out automatically based on a microcontroller using an LCD, ultrasonic sensor HC-SR04, servo motor MG996R and SIM800L V2.0 module. The method used in this study is to measure the height of the garbage on the surface of the river which is detected by ultrasonic sensor 1, where the height of the garbage on the surface is h ? 10 cm, the servo motor will lift the garbage to the reservoir. Garbage in the reservoir will be detected by ultrasonic sensor 2, where the height of the waste from the surface of the tub h ? 15 cm, the LCD will display the condition of the waste and the waste height data is managed by the microcontroller and sent in the form of SMS to the number embedded in the GSM SIM800L V2.0 module. The results of the characterization of the ultrasonic sensor HC-SR04 obtained a sensitivity value of 1.2353 V/cm and a linear regression value of 0.9918. The MG996R servo motor can work well where the average error is 0.04% and can lift garbage weighing up to 350 grams. The ability of the servo motor as a whole is influenced by the form of garbage removal which is still simple. The results of the overall tool test show that this design can monitor and lift garbage in the river automatically even though when the tool is working the overall voltage drop occurs but the tool still works wel.
