The burglary of a safe in the city of Jombang, East Java, lost valuables belonging to the Cemerlang Multipurpose Trading Cooperative. Therefore, a security system tool was created in the safe that serves as a place to store valuables and important assets. Change the security system using the security system with a private unique method with modulo arithmetic pattern. The security system of the safe is designed in layers which are attached with the RFID tag by registering and then verifying it on the card. Entering the password on the card cannot be read or is not performed, then the system will refuse to open it. arduino mega type 256 components, RFID tag is attached to the RFID reader, only one validated passive tag can open access to the security system, namely number B9 20 E3 0F. Meanwhile, of the ten passwords entered, only three match the modulo arithmetic format and can open the security system, namely password numbers 22540, 51324 and 91032. The circuit system on the transistor in the solenoid driver circuit works after the safety system opens. The servo motor can rotate according to the input of the open 900 servo angle rotation program.
