Indonesia Finalizes Key Survey for Pantura Sea Wall Project

KBRN, Abu Dhabi: The Ministry of Marine Affairs and Fisheries (KKP) has completed a comprehensive hydro-oceanographic survey of Jakarta Bay and Semarang waters, marking a strategic step in the government’s plan to construct a massive sea wall along Java’s northern coastline (Pantura).

The project is intended to protect one of Indonesia’s most densely populated coastal regions from worsening environmental threats. The survey was carried out in collaboration with the Indonesian Navy’s Center for Hydro-Oceanography (Pushidrosal).

Kartika Listriana, Director General of Marine Spatial Planning at KKP, said the collected data will serve as a scientific foundation for the North Coast of Java Management Authority (BOPPJ) in designing technical coastal protection measures.

She emphasized that the Pantura region is chronically vulnerable to tidal flooding, coastal erosion, and rapid land subsidence. “The challenges of developing coastal areas are becoming increasingly complex due to climate change, rising sea levels, and the fast rate of land subsidence in major cities,” Kartika said on Thursday, January 15, 2026, as quoted by Antara.

She noted that Jakarta Bay and the waters of Semarang are among the most at-risk areas, requiring data-driven interventions to ensure accurate infrastructure design and minimize environmental and social risks.

The survey, conducted between November 20 and December 29, 2025, involved extensive environmental and geological research. Using bathymetry and geophysics, the team mapped seabed depth and physical characteristics to identify stable foundations for construction.

Hydrodynamic modeling was applied to study current and wave patterns, while sediment analysis examined transport processes and water quality to anticipate long-term impacts on the coastal ecosystem.

Vice Admiral Budi Purwanto, Commander of Pushidrosal, reaffirmed the Navy’s full support for the project, stressing that all data collection followed national and international standards to ensure accuracy and reliability.

Sawarendro, Deputy I of BOPPJ, welcomed the survey’s completion, describing it as an urgent necessity for disaster mitigation. He said the findings will not only guide the sea wall’s design but also support broader redevelopment efforts in coastal cities across Pantura.

The government views the initiative as a long-term solution to strengthen resilience against rising tides and sinking land, safeguarding communities along Java’s northern coast. ***
