Bara (Indonesian for "embers") is a peat fire forecast and crew dispatch tool for Indonesia's
fire brigades. 2026 is Indonesia's worst fire season in over a decade: CREA estimates fire smoke
caused 3,560 deaths in Indonesia in September alone, Malaysia sent about 2 million students home in
October, and Singapore ranked among the world's most polluted cities. On 3 Nov 2026 satellites
still saw 1,506 fire detections across Sumatra and Kalimantan, nine times a typical day
this year. Peat fires smoulder underground and crews are few.

Each morning Bara brings in the latest NASA satellite fire detections and rain data, forecasts where
fire is likely to spread tomorrow (LightGBM on 1 km cells with peat and rain), ranks places by
risk, and gives each crew an ordered route for the day with an exact solver.

Satellites miss fire under smoke and underground, so rangers can answer back with a WhatsApp voice
note. Muse Voice Transcribe writes it down, Muse Spark 1.3 turns it into a structured report where
every field is backed by a quote, Bara finds the village, fixed rules update the risk, the solver
re-plans the routes.

It is tested honestly: on the 2023 season, held out and pre-registered, the forecast beat
"yesterday's fires" (average precision 0.162 vs 0.099), and crews following Bara reached 9.9% more
next-day fire with fewer visits (1,122 vs 1,974). On 2026 so far it scores 0.288 vs 0.195.
