Jakarta, INTI - The National Research and Innovation Agency (BRIN) has developed a new breakwater technology called BRINlock to strengthen port and coastal infrastructure amid the growing challenges posed by climate change.
More Stable and Efficient Breakwater Innovation
M. Zuhdan Jauzi, a researcher at BRIN’s Center for Hydrodynamics Technology Research, explained that BRINlock was designed as a single-layer armor unit with a strong interlocking system.
“BRINlock was developed as a single-layer armor unit with an organized placement pattern and strong interlocking characteristics, enabling greater hydraulic stability while reducing concrete usage,” he said.
The technology was created to address the limited availability of large natural stones and the growing demand for material efficiency in coastal infrastructure development.
In addition, BRINlock’s design allows for reduced concrete volume, making it more cost-efficient and environmentally friendly due to its lower carbon footprint.
Technology Testing and Broad Implementation Potential
During the development process, BRIN utilized computer-based Finite Element Analysis (FEA) modeling and produced hundreds of test specimens.
Testing results showed that the technology achieved a stability coefficient value of 20.54 and maintained a high stability level even after safety factors were applied.
“After incorporating safety factors, the stability value remained at a high level, reduced to 13, making the design safer,” he explained.
BRIN has also prepared patent documentation, which is currently undergoing the application process to obtain Granted Patent status.
The BRINlock technology is expected to become an innovative solution for developing stronger, more efficient, and more sustainable coastal infrastructure in Indonesia.
Conclusion
BRINlock reflects Indonesia’s growing focus on sustainable infrastructure innovation by combining stronger coastal protection with material efficiency and lower environmental impact. With its advanced interlocking design and ongoing patent process, the technology is expected to support more resilient and environmentally friendly coastal development projects across the country.
