Yogyakarta – BRIN Public Relations. Indonesia is an archipelagic country with a high tsunami potential. In this regard, the National Research and Innovation Agency (BRIN) through the Hydrodynamic Technology Research Center is ready to collaborate with the Meteorology, Climatology and Geophysics Agency (BMKG) in developing tsunami research. “We want to collaborate to jointly build a tsunami modeling system to support the Indonesia Tsunami Early Warning System or InaTEWS program. This system is referred to the merah putih (red and white) tsunami model,” said BRIN Acting Head of Hydrodynamic Technology Research Center, Widjo Kongko in a limited meeting with the BMKG, last Friday (04/3).

This meeting with BMKG was to discuss the merah putih tsunami modeling roadmap, which will start this year and next year. “We are optimistic that we can do it and hopefully it can go well,” he added. Widjo said that the Head of BRIN had emphasized that BRIN and BMKG can strengthen the cooperation, including in the field of tsunami research.

Meanwhile, Head of BMKG, Dwikorita Karnawati welcomed this collaboration. “BMKG is ready to cooperate to realize the sustainability of tsunami mitigation and modeling technology in Indonesia, as well as to regenerate the InaTEWS which was initiated in 2008,” she said. She hoped that the InaTEWS with this merah putih modeling can be realized within 1 – 2 years. Dwikorita acknowledged that Indonesia has quite many tsunami experts, therefore these resources need to be optimized. This knowledge needs to be passed on to the younger generation, and utilized for the interest of the Unitary State of the Republic of Indonesia.

The involvement of BRIN researchers in this collaboration is also to support BMKG in implementing the tsunami modeling working group consortium. “This tsunami working group has the task of planning policies in the field of tsunamis and supporting activities in a sustainable manner, both in the form of short and medium- term programs, as well as providing input on policy strategies for tsunami observation, tsunami data processing and analysis, modeling, dissemination and tsunami services, as well as emerging tsunami technology,” explained BMKG Deputy for Geophysics, Suko Prayitno Adi.

As a research unit that has been established since 1982, the Hydrodynamics Technology Research Center, particularly the Hydrodynamics Laboratory in Yogyakarta, has succeeded in patenting the BPPT-lock, which is an engineered concrete protection layer unit for breakwaters in ports or coastal protection. Widjo said, BPPT-lock has been used in several places since 2018, namely at the Pacitan Steam Power Plant, TPPI Tuban, and the Sanur Port, Bali, and many contractors in the port-coast sector are interested in using the BPPT-lock which is more stable in performance and economical.

In 2022, BRIN Hydrodynamic Technology Research Center, particularly the Laboratory in Yogyakarta, was involved in research at the program home of disaster technology through BRIN Technology Assessment and Application Research Organization. This program house accommodates disaster mitigation research, ranging from early warning technology, prevention and mitigation, preparedness, emergency response, rehabilitation, to reconstruction engineering-design. “We are continuing our previous research by developing artificial intelligence-based tsunami prediction modeling and optimizing hybrid designs to mitigate the impact of tsunami threat,” said Widjo.
