Landslide followed by debris flow on February 22, 2018 has caused physical and psychological damage to Pasir Panjang village which hard to forget. Residents still frightened by a similar potential disaster in their village. A series of efforts were made to increase preparedness for similar potential disasters. These efforts include modeling the debris flow on 22 February 2018 run-out distribution, carrying out the boundaries of its hazard zones, transfer knowledge on debris flow emergency response. This series of efforts is Institut Teknologi Bandung community service program to apply knowledge in disaster mitigation activities. The results of debris flow numerical simulation model on February 22, 2018 were able to show the distribution of debris material. The model has 0.3 material concentration, 275 thousand m3 debris volume, 26 km/hour flow rate maximum speed, and flows as far as 2.3 km. Based on the results model, the debris flow hazard zones can be determined. The information is used as an analogy for hazard zone in several locations that has debris flow potential in Pasir Panjang Village
