Prototype of an Attendance and Entrance Access Based on RFID for Lab-Based Education (LBE) Learning Model

In this study, it is made an attendance system and RFID-based access to the entrance by using Arduino Uno as the controller and RFID module RC-522 as a reader. LBE based learning model focuses on research and development activities undertaken by students in the laboratory, the assessment indicator is the amount of time spent by students. RFID technology is used as an access for entering the laboratories and to record personal data at the same time, as well as the time of entry and exit time of the lab members. The difference between the time of entry and exit which will then be recorded and then added together as a whole as absenteeism. RFID Reader is used to read passive tags containing a unique code, which is stored as a unique code for each user ID. Passive tags have no internal power supply and depend on RFID reader to transmit data. In addition, the use Solenoid Door Lock as automatic door locks and Microsoft Visual Basic as the user interface. On the user interface will be calculating the total time each user, which is the accumulated total time difference between the time the user first scans reader and subsequent scans. The system is designed with the state if the ID is registered then Visual Basic will send a signal to the Arduino to unlock and vice versa. Users who registered and then his name will appear on the start menu user interface and the process of counting time will begin until the user begins to scan the tag for the second time. In testing, it is conducted test of reading the distance of the reader with a maximum reading distance of 3cm results, as well as testing the system as a whole which is in accordance with the design.
