Indonesia school collapse: 1 dead, dozens injured, 65 students trapped under rubble

How did the Indonesia school collapse happen and why were so many students trapped inside?

Indonesia was jolted by tragedy on September 29, 2025, when the Al Khoziny Islamic Boarding School in Sidoarjo, East Java, collapsed during afternoon prayers. The disaster left one student dead, dozens injured, and at least 65 students initially feared trapped beneath the rubble. Rescue teams rushed into action as frantic families gathered outside the disaster site, clinging to updates scrawled on whiteboards and shouted through megaphones by officials.

The collapse occurred during a routine prayer session when male students were gathered in a wing of the building that had recently undergone an unauthorized vertical expansion. Investigators suggest that the structure, originally built as a two-story facility, had been expanded to include a fourth floor poured in concrete without proper authorization, permits, or engineering oversight. The foundation could not bear the load, and part of the structure crumbled, sending debris cascading over students and sparking a desperate search for survivors.

Rescue agencies confirmed that more than 102 people were evacuated in the first hours, while 38 remained missing as of the latest reports. Hospitals in the region received 77 patients, many of them children with broken bones and critical head injuries. Survivors trapped under concrete were kept alive thanks to oxygen cylinders, water pipes, and the painstaking work of rescue personnel who avoided using heavy machinery for fear of triggering further collapses.

Why is unauthorized school construction such a persistent safety risk in Indonesia and Southeast Asia?

This disaster has revived urgent questions about construction standards in Indonesia, particularly within privately funded religious institutions. Islamic boarding schools, known as pesantren, play a major role in the country’s education system, housing and teaching millions of students. Many of these institutions rely on community donations for expansions, often moving quickly to build extra dormitories or prayer spaces without sufficient regulatory oversight or safety compliance.

Vertical expansion has become one of the most dangerous practices in this environment. Adding floors to structures built with shallow or undersized foundations frequently leads to instability. Without reinforced columns, weight distribution planning, or soil analysis, the base cannot absorb the additional load, especially during peak occupancy. In the case of the Al Khoziny school, early reports suggest that concreting work on the fourth floor was ongoing at the time of collapse, directly weakening the existing foundation.

Indonesia’s construction sector has long battled problems with compliance and enforcement. While urban centers like Jakarta and Surabaya have stricter building codes, rural and semi-urban areas often see less supervision. Overlapping jurisdictions between local, provincial, and national authorities complicate oversight, leaving schools, hostels, and religious institutions at risk, particularly when expansions are treated as urgent community needs rather than long-term infrastructure projects.

How does Indonesia’s vulnerability to earthquakes and natural disasters amplify the risks of weak infrastructure?

Indonesia’s geographic reality amplifies these risks. The country sits along the Pacific “Ring of Fire,” making it one of the most disaster-prone nations in the world. Earthquakes, volcanic eruptions, and floods regularly challenge its infrastructure. The combination of seismic vulnerability and unauthorized building practices creates a perfect storm that heightens the risk of human casualties.

Past incidents underline this dangerous intersection. The 2006 Yogyakarta earthquake killed more than 5,700 people, many of them victims of collapsing poorly built homes and schools. In 2018, the Lombok earthquake flattened thousands of buildings, exposing again how non-reinforced structures crumble under stress. Schools and dormitories have been particularly vulnerable because they often house children in concentrated spaces with limited exits.

Experts point out that even if an earthquake was not the immediate cause of this collapse, Indonesia’s inherent geological risks demand stricter building codes. Structures in quake-prone zones must be designed with reinforced concrete, steel frameworks, and seismic dampers. The lack of compliance magnifies tragedy when structures are not built to withstand even moderate stress.

What have authorities and rescue teams done so far to save students and prevent further collapse?

Local and national disaster mitigation teams, supported by soldiers and police officers, have been leading a round-the-clock rescue operation since the collapse. Rescuers have faced the delicate task of balancing urgency with safety. The rubble has been unstable, forcing teams to stabilize slabs manually before cutting through. Excavators and heavy cranes were initially withheld to avoid triggering further collapses and worsening the disaster.

Officials confirmed that survivors trapped under debris were supplied with oxygen and water to keep them alive while teams carved small tunnels through the concrete. Night operations have been especially risky, requiring floodlights, harnesses, and careful coordination. The emotional strain has been overwhelming, with parents waiting outside hospitals and rescue camps, many breaking down when names of missing children were read aloud.

The government has promised compensation to the families of victims and medical support for those injured. Provincial disaster agencies have launched inquiries into the school’s construction permits and the role of contractors involved in the expansion project, signaling possible legal action.

Why are unauthorized expansions so common, and what policy reforms could prevent tragedies like this?

The broader problem lies in the disconnect between demand for educational space and the pace of regulatory oversight. Islamic boarding schools are often community-driven, operating outside the government’s direct financial support structure. As enrollment grows, schools face pressure to expand quickly. Local contractors, eager for work, sometimes undertake vertical expansions without formal approval or safety certification.

Enforcement is hampered by overlapping jurisdictions, resource shortages, and corruption in permit systems. Analysts suggest that unless the Indonesian government strengthens monitoring, introduces mandatory structural audits, and criminalizes unauthorized vertical expansions, the cycle of collapses will continue.

Policy experts are calling for a national audit of school buildings, particularly in disaster-prone regions. Japan, for example, has invested heavily in retrofitting schools to meet earthquake safety standards. Indonesia, with its frequent natural disasters, faces pressure to replicate such initiatives. Without this, educational institutions will remain vulnerable to sudden collapses.

What does this collapse reveal about the intersection of education, safety, and governance in Indonesia?

The Al Khoziny school tragedy is more than an isolated accident. It underscores how governance gaps intersect with social and educational realities. Pesantren institutions provide affordable and accessible education to millions, yet their rapid, unregulated growth exposes students to risks far beyond the classroom.

Images from East Java—children being carried out of rubble, parents waiting in anguish, and communities rallying around hospitals—have already galvanized public opinion. This tragedy will likely push the government into new reforms, with louder calls for stricter oversight of boarding schools, mandatory disaster readiness drills, and comprehensive inspections of all educational facilities.

At the same time, the tragedy reflects a deeper governance dilemma: balancing the autonomy of community-run religious schools with the state’s duty to protect its citizens. Stricter oversight, if poorly managed, could trigger resistance from religious groups that value independence. Policymakers will have to strike a careful balance between respecting cultural traditions and enforcing national safety standards.

What lessons can be drawn from this disaster and what is the way forward for Indonesia?

The collapse of the Al Khoziny Islamic Boarding School serves as a stark reminder of the cost of ignoring structural safety in pursuit of rapid expansion. Indonesia’s construction and education authorities now face a test of credibility—whether they can learn from this incident and enforce meaningful reforms.

Rescue efforts are still underway, and the final death toll remains uncertain. Yet the central message of this tragedy is clear. Students were trapped and lives were lost because of unauthorized construction and weak enforcement of safety standards. The path forward requires more than immediate rescue operations. It demands accountability, regulatory reform, and a nationwide rethinking of how schools are built in one of the world’s most disaster-prone regions.

If Indonesia can place student safety at the core of infrastructure decisions, this moment of grief may yet become a turning point. Without such action, the country risks repeating the same mistakes, with future generations once again paying the price.
