Sistem Pemanggilan Wisuda Menggunakan RFID (Radio Frekuensi Identifikasi ) Berbasis IoT (Internet of Things) secara Otomatis

Abstract

In the Computer Science Undergraduate Study Program at the University of North Sumatra, the graduation ceremony for students at the University of North Sumatra is currently still done manually, this manual process tends to be slower and requires greater effort on the part of the committee. This can cause human errors in processing the list of participants, the calling process and irregular times. To overcome the weaknesses that existed in the previous graduation calling system, a microcontroller was used, which is a form of semiconductor technology that is currently popular. The Radio Frequency Identification (RFID) system is a technology that can detect user identity, where this process is unique because it does not have to come into direct contact with the RFID Reader. In fact, RFID technology provides many benefits that can be utilized in various areas of life. RFID technology operates using an identification system that relies on radio waves. This system requires at least two devices a tag and a reader. During data scanning, the reader interprets the signal emitted by the RFID tag.When students want to carry out graduation activities, they only need to hold their RFID bracelet on their wrist to the RFID reader model RC522 which is connected to the system. The system will read information from the RFID Wristband, verify the student's identity, and automatically record their attendance in a database connected to the website. And this system was tested 5 times with a distance of between 2-5cm and 6-10cm on the RFID bracelet and reader which concluded that the RFID bracelet would be read by the system if the distance between the RFID bracelet and the reader was 2-5cm.
