BUILDING A WASTE SORTING TEACHING DEVICE WITH RFID TECHNOLOGY FOR ELEMENTARY SCHOOL STUDENTS

Abstract

The research aims to create waste sorting teaching equipment for primary school students. Students will be able to separate four types of waste: general waste, organic waste, hazardous waste and recycle. Teaching equipment consists of 4 small plastic tanks, made into simulated trash cans.  Each tank is equipped with a Radio Frequency Identification Scanner (RFID Scanner) for each type of waste and a monitoring microcontroller Arduino UNO R3 and there will be 20 garbage image cards, of which 5 cards for each type of waste. On the card, install the RFID of the type of waste.  In the training, when each garbage card touches the tank's RFID scanner, it scans the signal to the controller, which checks if it is correct. If right, it will sound "right type" and the lid will open. If it is wrong, it will sound "wrong type" and the lid will not open.  When the teaching equipment was tested on 6 primary school teachers and 12 students in Grade 1-6, the evaluation results (based on a full score of 5) showed that the research was practical, with an average score of 4.8, and overall satisfaction with score at 4.4. For knowledge gain, it was mentioned by the users that the teaching equipment had a clear purpose with average score of 4.8, and can be a good tool for educational use with the average score at 4.6.
