The Coastal Protection Feasibility Study in Bintan Regency aims to mitigate coastal erosion and ensure the sustainability of shorelines in Bintan Island, Malang Berdaun Island, Berakit Island, and Sentut Island. Executed by PT. Globetek Glory Konsultan under the coordination of Balai Wilayah Sungai Sumatera IV, this project is designed to construct reinforced concrete revetments that can withstand harsh coastal environments.

The study includes technical, hydrological, and geological assessments, along with the development of an optimal construction design. While the four locations are not classified as high-priority in terms of technical urgency, this project plays a strategic role in strengthening national border areas and protecting Indonesia’s outermost islands. Using K175 concrete with Portland Cement Type V, the revetments are engineered for durability, while toe protection consists of 200-300 kg rock layers for added stability.

In addition to technical aspects, the project complies with environmental regulations, as revetment structures under 1 km in length are exempt from AMDAL requirements and only require UKL-UPL documentation. Overall, this initiative is a crucial step in preserving coastal areas, safeguarding Indonesia’s maritime territories, and reinforcing the country’s outermost island defenses.
