The land sinks.
The tide rises.
Ten years to act.
Semarang is not a greenfield. It already runs BRT, ATCS, flood sensors, and a decade of digital services — fragmented across fifty apps while the coast subsides. This master plan integrates what exists, puts resilience first, and treats operations as the product.
Not a greenfield.
The systems exist. What's missing is integration, operations, and the right priority order. Phase 0 money goes into plumbing — not new apps.
Three theses before procurement.
Most Indonesian smart-city programs fail at procurement and operations, not technology. These rules are the difference between a platform and a graveyard of dashboards.
Resilience first.
Subsidence and tidal flooding are existential. Hydromet sensing, pump SCADA, and InSAR monitoring are Tier-1 — chatbots are not.
Integrate before innovate.
Fifty apps already exist as islands. One data platform, one identity, mandatory APIs — before any new point solution is bought.
Operations over launches.
Every capex item carries a funded 5-year O&M plan, city-owned data and code, and an exit clause. No lock-in, no dead dashboards.
Six domains. One platform.
Every domain rides the same plumbing. The program map below is the whole plan on one screen — explore each domain in detail on the next page.
