The 30.16-kilometer sea fence in Tangerang spans 16 villages across six sub-districts. While initially perceived as a community-driven initiative to protect coastal areas, its construction has sparked debates. Local fishermen argue that the fence has severely impacted their livelihoods, obstructing access to fishing grounds. Questions about its legality and environmental impact have further fueled the controversy.

Bekasi’s Bamboo Barrier: A Port Growth Project

In Bekasi Regency,a similar bamboo barrier was erected as part of a port expansion project.Proponents claim the fence is essential for preventing erosion and facilitating port development. However,critics argue that the project lacks transparency and fails to consider its broader ecological and social consequences. The clash between economic growth and environmental preservation remains a central issue.

The Navy’s Intervention

The Indonesian Navy’s involvement marked a turning point in the sea fence saga.On January 18, 2025, under president Prabowo Subianto’s directive, 300 naval personnel were deployed to dismantle the structure. The operation highlighted the government’s commitment to addressing community concerns and ensuring compliance with environmental regulations.

Pros and Cons of Bamboo Sea Fences

Bamboo sea fences offer several advantages, including cost-effectiveness, ease of construction, and environmental friendliness. They are especially effective in wave dampening and sediment accumulation. However, their limitations are equally important. They can disrupt marine ecosystems, hinder fishing activities, and require frequent maintenance.As Tuan Thieu Quang noted, “While bamboo sea fences serve as an alternative to concrete wave breakers, their long-term sustainability remains questionable.”

conclusion

The saga of the bamboo sea fences in Tangerang and Bekasi underscores the complex interplay between environmental protection,economic development,and community welfare. While these barriers offer a practical solution to coastal erosion, their implementation must balance ecological impact and social equity. As coastal challenges intensify, innovative and inclusive approaches will be essential to safeguarding both natural resources and human livelihoods.

As the world confronts the growing effects of climate change, the search for effective coastal protection strategies has become more urgent. in Indonesia, the use of bamboo sea fences has ignited a heated debate about their effectiveness and the unintended consequences they bring, especially for local fishing communities.

Andreas Aditya Salim, Program Director at the Indonesia Ocean Justice Initiative (IOJI), believes bamboo sea fences may not be the best solution for addressing climate change or aiding adaptation efforts. “I think there are other more effective ways if we want to talk about climate change mitigation or adaptation,” Salim commented during a phone interview on January 13, 2025.He stressed that restoring and planting mangrove forests or coastal vegetation could deliver more sustainable and impactful outcomes.

Despite their intended purpose, these sea fences have caused significant issues for fishermen in Bekasi. Mitun, a 28-year-old fisherman, shared his struggles with the barriers, emphasizing how they disrupt daily fishing operations and livelihoods.

The Rise of Bamboo Sea Fences

The origins of these bamboo structures remain somewhat unclear, but the Pantura People’s Network (JRP) has acknowledged their role in their construction. JRP Coordinator Sandi Martapraja explained, “The sea fence that stretches along the north coast of Tangerang Regency was deliberately built independently by the community,” as reported on January 11, 2025.However, the Ministry of maritime Affairs and Fisheries (KKP) has declared these structures illegal, citing their lack of proper licensing and the disturbances they create for local fishermen.

Bekasi’s Coastal Project Challenges

In Bekasi, a massive two-kilometer-long bamboo fence, spanning 70 meters in width, stretches across the waters of Segarajaya Village. The West Java Provincial Government clarified that this structure is part of the Paljaya Fish Landing Base (PPI) port development project.Ahman Kurniawan, Head of the muara Ciasem Fisheries Port UPTD, stated, “So later on land, we will build the PPI so that fishermen will be centralized to conduct fish auctions at the Paljaya PPI,” on January 14, 2025. The project aims to streamline the movement of fishermen, making it easier for them to load and unload their catch.

The Navy’s Role in Dismantling the Fences

on January 18,2025,the Indonesian Navy began dismantling the bamboo sea fence in tangerang,acting on a directive from President Prabowo. Frist Admiral I Made Wira Hady, Head of the Navy’s Data Service, confirmed, “This task is a direct instruction from President Prabowo through TNI commander General Agus Subiyanto to us.” The operation involves 300 personnel, including local residents, and is expected to continue until the barrier is entirely removed.

Weighing the Pros and cons

While bamboo sea fences are frequently enough praised for being cost-effective and environmentally pleasant compared to concrete alternatives, they are not without their flaws.Research shows that these structures have limited effectiveness in combating erosion over the long term.Even though they can trap sediment and reduce wave energy, they demand frequent maintenance and are frequently enough unable to withstand extreme weather conditions.

Conclusion: The Balance of Coastal Management

The controversy surrounding the bamboo sea fences in Tangerang and Bekasi underscores the delicate balance between protecting coastlines and supporting local livelihoods.While these barriers aim to reduce erosion and bolster fishing activities, their unregulated construction has created significant challenges. As the Navy works to dismantle these structures, the broader conversation about sustainable coastal management continues, highlighting the need for solutions that benefit both the environment and the communities that depend on it.
