Global investors are eyeing the Indonesian archipelago for sustainable opportunities, yet many overlook the immense potential of the marine sector. Seaweed farming has emerged as a flagship commodity, offering a lucrative alternative to traditional agriculture while restoring coastal ecosystems across the nation’s 17,000 islands.
However, shifting from raw exports to downstream processing presents complex regulatory and operational hurdles for foreign entities. Understanding the government’s 2026 roadmap is essential for navigating these challenges and capitalizing on the nation’s Blue Economy Growth.
This guide breaks down production targets, risks, and investment pathways for prospective stakeholders. For precise data and strategic planning, the Ministry of Marine Affairs outlines the government’s vision driving this maritime transformation.

Strategic Role of Seaweed in the Maritime Economy
The Indonesia Blue Economy Roadmap 2023–2045 has identified the ocean as a primary engine for national development. Within this framework, marine capture fisheries, aquaculture, and processing account for approximately 83% of the ocean-economy output. Seaweed stands out not just as a commodity, but as a critical driver for Blue Economy Growth, serving as a sustainable source of bio-products and a generator of coastal employment.
Designated as one of five “flagship commodities” in the national marine-fisheries policy (RPJMN), seaweed is pivotal for export earnings and climate resilience. With its extensive tropical coastlines, Indonesia is uniquely positioned to dominate the global market for carrageenan and alginate. The strategic focus is shifting from merely exporting raw dried seaweed to developing a robust domestic processing industry that retains value within the country.
Production Status and 2026 Outlook
Indonesia is a titan in the global seaweed market, having produced nearly 10 million tonnes in 2023. This volume represents roughly 30% of the global supply, underscoring the nation’s dominance. The Ministry of Marine Affairs and Fisheries (KKP) has set ambitious targets, aiming for 12.3 million tonnes by the end of 2024, with projections signalling continued expansion through 2026.
Despite these impressive figures, the sector faces challenges regarding consistency. Official assessments have noted a plateau in production in certain regions due to seed quality degradation and environmental factors. However, the outlook for 2026 remains positive as the government pushes for modernization. The focus is now on stabilizing yields through better technology to ensure that the aggressive quantity targets do not compromise the quality required by international buyers.
Policy Pillars and Government Support
To realize the potential of Blue Economy Growth, the government has implemented specific interventions focused on infrastructure and capacity building. A key initiative is the development of “seaweed farming villages” (Kampung Rumput Laut) in eastern provinces like Nusa Tenggara Barat (NTB) and South Sulawesi. These hubs are designed to centralize production and improve logistics for farmers.
National roadmaps emphasize the urgent need for improved seedstock, specifically tissue-culture seedlings that are more resistant to disease and climate variations. Furthermore, the government is working with development partners like the FAO to align seaweed expansion with Sustainable Development Goals (SDGs). These policies aim to create low-carbon protein sources and provide equitable employment opportunities for women and youth in rural coastal areas.
Practical Basics of Farming Operations
For investors looking to enter the sector, understanding the on-the-ground reality is crucial. The primary species farmed in Indonesia are tropical red seaweeds, specifically Eucheuma and Kappaphycus for carrageenan, and Gracilaria for agar. These are typically cultivated using simple line and raft systems in shallow coastal waters, minimizing the need for heavy industrial machinery.
Production hubs are concentrated in eastern Indonesia, where local Dinas Kelautan dan Perikanan (DKP) offices coordinate farmer groups. A typical farm setup involves securing site allocation, often through customary permissions, and registering with local cooperatives. While the gear required—ropes, floats, and stakes—is basic, success depends heavily on adherence to proper spacing and seasonal timing to maximize growth cycles.
Value Chain and Downstream Opportunities
The real investment opportunity lies in disrupting the traditional value chain. Historically, Indonesia has exported raw dried seaweed, losing out on the higher margins available in processing. Current policy documents repeatedly stress the need for downstream industrialization, creating a demand for factories that can produce semi-refined carrageenan, bioplastics, and cosmetic ingredients.
A dedicated national roadmap guides foreign and domestic investment into these processing clusters. Integrated farm-to-factory models are being promoted to bridge the gap between smallholder farmers and global markets. Business-matching forums are increasingly highlighting companies that can process seaweed domestically as model cases for scalable, export-oriented ventures within the modern blue economy.
Real Story: Scaling Production in Nusa Penida
Meet Alder, a 42-year-old innovator from Brussels, Belgium who moved to Bali not to surf, but to solve a plastic crisis. His vision was clear: convert Eucheuma cottonii seaweed into biodegradable packaging.
In early 2024, Alder hit a wall. While Nusa Penida had the seaweed, the supply chain was chaotic. Middlemen were mixing premium seaweed with low-grade scraps, ruining Alder’s bioplastic prototypes. He was burning cash and losing patience.
Alder took a gamble. He bypassed the brokers and sat down directly with the farmers in Batununggul village. The negotiations were tough—conducted in broken Indonesian amidst the heavy smell of drying seaweed. But he offered a game-changer: a fixed-price contract at 10% above market rates in exchange for strict quality control.
It worked. The farmers honored the deal, and high-quality “green gold” began flowing into his warehouse.
However, success brought a new enemy: bureaucracy. As Alder’s export volume exploded, his small setup triggered red flags with the tax office. He wasn’t just a buyer anymore; he was a manufacturer. Overwhelmed by the complex tax liabilities of his foreign-owned company (PT PMA), Alder realized his factory was at risk of being shut down for non-compliance.
Instead of fighting the paperwork alone, he brought in a specialized tax management team to restructure his operation. With his compliance secured and his supply chain stabilized, Alder now exports to three European countries—proving that in Indonesia, you need to master both the ocean currents and the paper trail.
Key Risks and Operational Constraints
Despite the optimism, the sector is fraught with biophysical and market risks. Climate change poses a significant threat, as rising sea-surface temperatures can lead to ‘ice-ice’ disease (a bleaching condition) and epiphyte outbreaks, which devastate crop yields. Extreme weather events, becoming more frequent, can destroy simple raft systems overnight.
Structurally, the industry suffers from deteriorating seed quality. Many farmers rely on vegetative propagation from old stocks, leading to weaker strains over time. Market volatility is another major constraint; farm-gate prices fluctuate wildly based on global demand, often leaving smallholders vulnerable. Investors must account for these variables and invest in supply chain resilience to ensure long-term viability.
Regulatory and Licensing Considerations
Seaweed farming falls under strict aquaculture regulations coordinated by the KKP and local marine agencies. For foreign investors establishing a PT PMA, compliance with Indonesia’s investment laws is mandatory. This includes adhering to spatial planning rules that designate specific zones for aquaculture to prevent conflict with tourism or conservation areas.
The guiding principle for new projects is ecosystem-based management. Intensive expansion in sensitive habitats, such as coral reefs or seagrass beds, is heavily restricted. While the government encourages Blue Economy Growth, it does so with strict carrying-capacity limits. Prospective investors must navigate the Online Single Submission (OSS) system and verify their location against the local spatial plan (RZWP-3-K) to ensure their permits are valid and secure.
