PT Citia Engineering Indonesia held the second session of its Micro-Webinar series on Friday 6 November 2026 at 14.00 WIB. The title was Always-On Terminal: High Availability Server OT pada Terminal Automation System, with the subtitle Triple-Layer Auto Failover: Server, Network & Database.
The session was online, free and short, 15 to 20 minutes. Fadli from Management System Engineering at Citia presented it. The poster addressed maintenance, instrumentation, automation, IT/OT and terminal operations staff, and RSVP ran through siTia on WhatsApp.
The three layers on the agenda
Server
Failover from the main unit to the standby unit.
Network
Redundancy through backup paths and backup switches.
Database
Replication so transaction data stays intact.
The session opened with the reason behind all three: why the OT server at a terminal has to stay up. In a terminal automation system the servers carry the applications operators use for daily distribution work. Citia's Padalarang TAS lifecycle support, for instance, maintains the TAS server, the FD-Flow PC and the gate interface PC, and makes a database backup on the server during each monthly visit.
Citia has not published a recording or slides of the session yet. The session page, Micro-Webinar #02: Always-On Terminal, will be updated if either becomes available.
