ABSTRACT Employee attendance is an important factor for an agency or company to achieve goals, this is related to discipline and has an impact on the performance of each employee. Therefore, it is necessary to have special data collection to record attendance and absences so that work activities can be recorded in real time and well. There are many ways that can be done to achieve a good attendance information system, one of which is using computer technology where it is applied with a website-based attendance application.
