Pemanfaatan Sistem RFID sebagai Pembatas Akses Ruangan

In this research, RFID system was utilized as a personal identification security card in access room system. This system was aimed to secure a room and to have privacy from unauthorized person to enter the room. By designing and implementing the system, a solenoid based electric key system as well as an optimal distance and position of RFID tag were evaluated to know the most convenience condition for all users during accessing the room. RFID tag used in this system was a card type of EM4001 that has a unique code as a personal identification. This code was read by an ID-12 RFID reader and then validated by microcontroller ATMega32 to control a customized electric key. This system was also equipped with database system to record some users who accessing the room. The results showed that 100% of RFID tag could be read by RFID reader in three different positions with optimum distance of 5cm vertically and 2cm horizontally. All users’ activities during accessing the room have been recorded successfully by database system. This research concluded that RFID technology could be applied conveniently and securely as an alternative of personal identification system to access a room.
