Buddy-punching, phone clocks turned back, spoofed GPS, records edited after the fact. How CoalTrack closes each gap — and the one feature we removed because it didn’t work.
We build software that holds up in the field.
We make CoalTrack — attendance and payroll for coal mining, live in production — and AgroTrack for palm-oil estates. The same team designs and builds web and mobile software for clients anywhere.
Coal mining — the industry CoalTrack was built for.CoalTrack worker app — one tap, timed by the server.

Built for the pit and the estate.
Our own software, running where signal is thin and every hour on the payroll has to be provable.
CoalTrack · Coal mining · Live
Attendance you can’t fake. Payroll that follows the law.
Workers check in with one tap — on the server’s clock, with real GPS, from one approved phone. Payroll follows from the hours actually worked: overtime, BPJS, PPh 21 TER, and a payslip in every inbox.

The same engine, built for the estate.
Harvest premiums computed from each harvester’s bunches, production from block to mill, fertilizer stock and purchase requests — and one portal for groups running many estates.

CoalTrack turns attendance into a compliant payroll run — PPh 21 TER, BPJS, overtime — and writes the engine twice so the server and the phone agree to the rupiah.
