A location-based attendance system built to make it easier for State Civil Apparatus in the Tulungagung Regency area to carry out attendance electronically without having to queue for both entry and return attendance, without losing the function of the attendance machines that have been installed in each OPD in Tulungagung Regency, because personnel data has been integrated between attendance via machine and via smartphone.It is hoped that this application will make it easier for ASNs to carry out attendance within the Tulungagung Regency Government.
