Al-Khoziny Islamic Boarding School collapse

The Al-Khoziny Islamic Boarding School collapse occurred on 29 September 2025 in Sidoarjo Regency, East Java, Indonesia, when a three-story prayer room at the Al-Khoziny Islamic Boarding School (pondok pesantren) collapsed while students were performing congregational Asr prayers. On 7 October 2025, the National Search and Rescue Agency reported 67 deaths, 103 injuries, and 8 unidentified body parts which might belong to the same victim. According to the National Agency for Disaster Countermeasure (BNPB), the collapse was the deadliest non-natural disaster in Indonesia in 2025.

The building was initially two stories tall, with expansion work underway at the time of the collapse. Investigators have pointed to overloading of vertical supports and foundation elements, alongside possible unauthorized construction and insufficient permitting, as leading causes of the catastrophic failure. The collapse led to wide regional and national scrutiny of building safety in pesantren, intensified calls for regulatory reform, and formal demands for accountability from school management and local officials.
