Forest fire smoke pushed Jakarta's air quality into unhealthy range on Sunday afternoon, with IQAir showing an index of 152 and PM2.5 as the main pollutant. The Ministry of Environment and Forestry's own index reached 122 near HI Roundabout, and forecasters expected conditions to worsen before easing around 9 p.m. BMKG says the smoke came from fires outside the capital and is gradually dissipating, though remnants remain off western Banten. The story is a useful reminder that transboundary haze is a recurring regional problem, not just a local one. Jakarta's plan to run water mist systems is a short-term response and does little to address the land and fire management practices that produce the smoke. For readers tracking climate and environmental policy, this points to the need for stronger coordination on fire prevention and land use across Indonesia, not just better air quality alerts.
