The Sidoarjo Mudflow disaster, which began on May 29, 2006, remains an ongoing environmental challenge with no signs of stopping. Located in Siring Village, Porong District, Sidoarjo Regency, East Java, the mudflow has caused severe subsurface instability, requiring continuous mitigation efforts. Under Presidential Regulation No. 21/2017, the responsibility for mudflow management was transferred to the Ministry of Public Works and Housing (PUPR), which established the Sidoarjo Mudflow Control Center to oversee operations.

Due to weak soil bearing capacity, frequent embankment slides, and seepage at several points, reinforcement of the mud retaining embankment became essential. In 2023, the government initiated the Supervision of Embankment Strengthening project, with the Supervision Consultant tasked to ensure safe, effective, and sustainable embankment improvement.

🔸 Scope of Work

• Continuous supervision of mud retaining embankment strengthening works, ensuring compliance with technical standards.
• Monitoring structural stability, addressing landslide risks, and preventing seepage through advanced inspection and instrumentation.
• Conducting routine, periodic, and annual inspections to evaluate functional and structural integrity.
• Implementing maintenance and repair strategies to extend the embankment’s service life.
• Coordinating with stakeholders to support social, economic, and cultural activities affected by the mudflow.

🔸 Key Benefits

• Enhanced safety → improved structural integrity of the embankment, reducing flood and collapse risks.
• Sustainability → regular inspections and preventive maintenance to maintain service function.
• Community protection → securing surrounding settlements, infrastructure, and socio-economic activities.
• Disaster resilience → strengthening long-term mitigation capacity against the continuing mudflow phenomenon.

This project demonstrates Indonesia’s commitment to long-term disaster management, ensuring that the Sidoarjo Mud Retaining Embankment continues to safeguard both the environment and the community.
