DIMETRI TPJ
Mobile meter-reading app and Laravel backend for Perumdam Tirta Pandalungan field staff, replacing paper forms with on-site data capture, GPS verification, and anomaly detection.
SIMPEG TPJ
Location-based employee attendance app for Perumdam Tirta Pandalungan Jember, enforcing geofenced clock-in with GPS verification and integrating with the existing SIMPEG HR system.
Outcomes
- Digitized attendance with time and GPS validation to reduce disputes and manual tracking.
- Implemented geofencing with configurable site radius and adaptive GPS polling to prevent location spoofing while accounting for real-world GPS drift near building edges.
- Integrated with legacy SIMPEG backend so attendance records flow directly into salary calculations and performance evaluations without manual re-entry.
- Built supervisor manual override with audit trail so every attendance exception is logged and attributable without bypassing integrity controls.
