Rancang Bangun Alat Sistem Absensi Mahasiswa Menggunakan Rfid (Radio Frequency Identification) Berbasis Mikrokontroler Atmega 328 dengan Compiler Arduino Uno

Abstract

This study aim to develop a prototype of RFID attendance system Students University of North Sumatera by using Radio Frequency Identification (RFID) integrated with a database to support the overall performance as a substitute for manual attendance systems. This software uses Visual Studio 2010 Express, Microsoft Access and Microsoft Excel as a resource for writing attendance program. From Visual Studio 2010 Express will make Graphical User Interface (GUI). The GUI consist of 3 form such form formportserial, forminputdata and formdatabase. This software is written to make easier for administrator to record the student attendance based on subject and lecturer. The prototype of RFID attendance systems consist of several main components such as tags that will be used as a replacement of id cards, and reader that will read the information related to the students attendance. The integrated databae will allow the system to automatically store data directly to the database. As for the results of this final project is a prototype of RFID attendance system which has a function to store students attendance data, with a maximum reading range of 3 cm, with success probability of 100% and the minimum interval between readings of 2 seconds in order to archive an optimal functionability.
