CHAS: Mobile App for Heavy Equipment Transportation Management
ChallengeHeavy equipment transportation operations still recorded manually
Employees of PT. Cipta Hasil Sugiarto recorded attendance, daily activities, and heavy equipment transport documentation manually — making it hard to verify that employees were actually at their assigned location, easy to manipulate attendance proof, and scattering documentation across personal galleries.
SolutionA single Flutter app with GPS verification and centralized documentation
Anti-Fraud GPS Attendance
Six types of attendance (clock-in, break, return, clock-out, overtime start & end) with GPS coordinate verification, fake location detection, and selfies watermarked with time & location.
Daily Activity Documentation
Photos and videos of activities and heavy equipment transport — automatically compressed, watermarked, and stored centrally with an auditable history.
Multi-Verification Login
Login code from the server + WhatsApp confirmation + push notification (FCM/APNs) for automatic device verification — no self-registration.
