Over the past few decades, seaweed has emerged as one of Indonesia’s strategic marine commodities. With its vast coastline and favorable tropical waters, the country has become one of the largest seaweed producers in the world. In recent years, national seaweed production has continued to increase alongside the growing number of farmers and the expansion of cultivation areas across regions such as Sulawesi, Nusa Tenggara, and Maluku. The rising global demand for seaweed-based products, particularly for the food, cosmetics, and pharmaceutical industries, has further encouraged the growth of supply from Indonesia. However, behind this production growth, the national seaweed supply chain still faces several structural challenges that affect market stability and the welfare of farmers.
One of the main issues in the development of Indonesia’s seaweed supply is the sharp price fluctuation experienced at the farmer level. Most Indonesian seaweed is still sold as raw material or dried seaweed, making its price highly dependent on international market demand. When demand from importing countries declines, prices at the farmer level can drop significantly. This situation is further intensified by the country’s heavy reliance on a single export market, namely China. China is the largest buyer of Indonesian seaweed, which is then processed into derivative products such as carrageenan and various food additives. This high dependency on one market makes domestic seaweed supply highly sensitive to changes in trade policies or declining demand from that export destination.
Apart from market-related issues, raw material quality is also an important concern in Indonesia’s seaweed supply chain. Many farmers still face limitations in cultivation techniques, harvesting practices, and drying processes. Seaweed that is harvested too early or dried improperly can result in inconsistent raw material quality for processing industries. Consequently, several domestic processing plants face difficulties in securing a stable supply of seaweed that meets industrial quality standards. Another challenge is the relatively long distribution chain between farmers and exporters. Seaweed often passes through several intermediaries before reaching processing factories or export ports, meaning that the profit margin received by farmers is often relatively small compared with the value generated in international trade.
Despite these challenges, the potential for developing Indonesia’s seaweed industry remains very large. One of the opportunities increasingly discussed is strengthening downstream processing industries within the country. If more seaweed is processed into higher value-added products such as agar, carrageenan, alginate, or raw materials for pharmaceutical and cosmetic industries, the economic value generated could increase significantly. Furthermore, improvements in cultivation technology, post-harvest quality management, and distribution systems could help strengthen national supply stability. With the right strategies, seaweed could evolve from being merely a raw export commodity into a major marine industry that contributes significantly to economic growth and improves the livelihoods of coastal communities in Indonesia.
