Jakarta, INTI - Indonesia’s coastal regions are facing escalating impacts from climate change, including rising sea levels, tidal flooding, coastal erosion, and land subsidence, particularly along the northern coast of Java. These challenges are damaging settlements, threatening food security and fisheries, and disrupting port operations. Conventional concrete-based infrastructure is no longer sufficient, highlighting the urgent need for integrated, science- and technology-driven climate risk adaptation.
The coastal crisis has evolved beyond environmental degradation into a significant socio-economic issue, placing pressure on communities and weakening port performance as a backbone of national connectivity.
This was emphasized by Aprijanto, Principal Research Engineer at the Hydrodynamics Technology Research Center of BRIN, during his inauguration as Research Professor at an official ceremony held on March 31.
He explained that tidal flooding and land subsidence are eroding the livelihoods of fishermen and aquaculture farmers, increasing food vulnerability and weakening social resilience. Damage to ponds, land, and infrastructure has reduced fisheries production, while disruptions in port operations are lowering logistics efficiency and threatening strategic national maritime assets.
Limitations of Conventional Infrastructure
According to him, Indonesia’s current response to coastal challenges remains dominated by hard infrastructure approaches such as concrete embankments, seawalls, and pumping systems, which assume stable climate conditions.
“These systems are not adaptive to sea-level rise and extreme waves. They are easily overtopped, costly, and have limited lifespans. Without ecosystem integration and adaptive governance, such measures remain reactive and temporary, relying on repeated projects rather than sustainable solutions,” he noted.
Toward Adaptive and Integrated Coastal Solutions
He stressed that adaptive technological innovation must become the foundation of coastal resilience through the integration of hybrid infrastructure, artificial intelligence, integrated observation systems, and renewable ocean energy, enabling a shift toward anticipatory, adaptive, and sustainable solutions.
Hybrid infrastructure, he explained, combines adaptive engineering solutions, such as smart dikes, modern mounds, and permeable structures, with nature-based approaches including mangrove rehabilitation and ecosystem restoration. This integrated approach helps gradually reduce wave energy and tidal flooding, stabilize coastlines, and lessen pressure on hard infrastructure.
Its implementation has been shown to reduce coastal erosion by up to 60–70%, while simultaneously restoring ecosystems and improving the long-term income of coastal communities.
Artificial intelligence further transforms coastal adaptation from reactive to predictive by integrating tidal data, extreme weather patterns, satellite imagery, and field sensors. These systems can forecast tidal flooding 24–48 hours in advance in real time, supporting integrated early warning systems.
“This allows continuous monitoring, early detection of flooding and erosion, and data-driven decision-making, improving mapping accuracy, policy response, and coastal management efficiency,” he added.
Indonesia also holds significant potential for marine renewable energy derived from ocean currents, waves, and thermal gradients, particularly in straits and open waters. This energy can support coastal adaptation systems such as sensors, pumps, and early warning systems, while reducing dependence on fossil fuels.
Its adoption contributes to lower carbon emissions, improved long-term cost efficiency, and supports the development of green ports and a sustainable maritime economy.
Looking ahead, coastal adaptation research will focus on integrating artificial intelligence, high-precision spatial data, and real-time hydrodynamic modeling to improve the accuracy of climate risk predictions.
These efforts also aim to strengthen climate-responsive hybrid infrastructure and intelligent national ocean observation systems. Through digitalization and renewable marine energy, such research enhances both physical resilience and evidence-based, risk-informed governance.
He further explained that scientific contributions have led to the development of an implementation framework based on Technology Readiness Levels, socio-technical system approaches, and integrated models of technology acceptance and utilization, bridging innovation and operational policy.
This integrated adaptation model improves precision in climate response, strengthens national climate and maritime resilience, and promotes more efficient, risk-based public investment.
Strengthening maritime resilience, he concluded, depends on building coastal resilience as a foundation for national security, logistics stability, and maritime economic growth. Adaptive coastal protection reduces disruptions in ports and sea-based distribution.
“Scientific innovation through hybrid infrastructure, predictive artificial intelligence, and integrated coastal data systems enhances safety, minimizes risks to strategic assets, strengthens logistics connectivity, and improves national maritime competitiveness in a sustainable manner. This research reinforces evidence-based, risk-driven coastal adaptation policies, ensuring more adaptive, efficient, and sustainable coastal development,” he concluded.
Conclusion
Indonesia’s coastal crisis highlights the urgent need to transition from reactive, infrastructure-heavy approaches to integrated, science-driven solutions. By combining hybrid infrastructure, artificial intelligence, and renewable marine energy, the country can build a more resilient, adaptive, and sustainable coastal system while strengthening its maritime economy and national security.
