Volcanic ash is danger for aviation because it harms the flight engine. This study presented the simulation of volcanic ash dispersion with the PUFF-Langarangian methods. The data was conducted from the Tangkuban Perahu volcano, which was erupted on 26 July 2019 in West Java, Indonesia. The results simulated volcanic ash dispersion based on the ash concentration and altitude at 105 minutes after the eruption. Simulation results were then compared with the satellite image of volcanic ash dispersion from The Indonesian Meteorological, Climatological, And Geophysical Agency or BMKG. With correction factor −14.75°, then the α = 0.50717°, AR = 0.99138, the simulation was fit with the satellite image. The simulation results showed that the combination of PUFF and Lagrangian methods gave a better volcanic ash dispersion map.
