Where we work
Field track record
Dozens of projects and over 500 km of fiber route since 2018.
On this site we list regions and types of work. Client names and project references are available in our company presentation.
Featured project
Integrated security system for a power plant
An integrated security system for a coal-fired power plant site in Pacitan, designed and built by MLJT from the software down to the hardware. Pedestrian access uses two-step verification: an RFID card plus face recognition. Motorcycle and car access uses RFID cards linked to each owner's record, combined with number plate recognition. Cards are issued from a self-service kiosk, similar to an ATM, that reads and writes RFID cards and has a built-in card dispenser.
