Indonesia, with its abundant natural resources and biodiversity, has many untapped food sources. One such plant with great potential yet to be fully explored is the sago palm. As a climate-friendly food source, sago offers numerous advantages that can support food security and environmental sustainability in Indonesia.

Distribution and Physiology of the Sago Palm

The sago palm (Metroxylon sagu) thrives in tropical regions of Indonesia, particularly in Papua, Maluku, and Sulawesi. Indonesia is estimated to have around 5.5 million hectares of sago land, accounting for approximately 51% of the world’s total sago land (BPS). Sago grows well in wetland areas like swamps and peatlands, which are often unsuitable for other food crops.

Physiologically, the sago palm has a trunk rich in starch, which can be extracted and processed into various food products. The sago palm also has a strong root system that helps prevent soil erosion and land degradation.

Utilization and Production Potential

Sago has various applications in the food industry. Sago flour can be processed into a wide range of products such as noodles, bread, cakes, and even bioethanol feedstock. A single sago palm can yield between 150 and 300 kilograms of sago flour, with a harvest period ranging from 7 to 12 years (World Bank) (Databoks).

Beyond the food sector, sago also has potential in non-food industries. The fibers from the sago palm can be used as raw materials for paper production, while sago starch can be turned into bioplastics, a more environmentally friendly alternative to conventional plastics (Katadata).

Environmental Benefits

From an environmental perspective, sago offers several advantages over other food crops. The sago palm can absorb and store large amounts of carbon dioxide during its growth, contributing to climate change mitigation. Research conducted at Aklan State University, the Philippines, shows that sago plants have the highest carbon content during the rosette and flowering stages. The average total carbon content at the rosette stage is 0.16 kg or 35.68 kg/ha, while at the flowering stage, it is 0.04 t/ha and 23.29 t/ha (Databoks). Additionally, soil organic carbon in sago plantations reaches 11.6 t/ha, with total carbon content above and below ground estimated at 34.93 t/ha (Databoks).

Sago also has high water efficiency, making it suitable for areas with limited water access. Moreover, the deep root system of sago helps manage groundwater and maintain the balance of local ecosystems.

Sago as a Natural Paludiculture Practice

Sago can be cultivated in paludiculture, a form of agriculture practiced in wetlands with high groundwater levels and high peat moisture. Sago paludiculture can restore degraded peatland ecosystems while simultaneously sequestering significant amounts of carbon dioxide (CO2) from the atmosphere (Databoks).

Sago’s Role in Traditional Food Needs

Before rice became the primary food policy in Indonesia, sago had long been a staple food for many traditional communities in Eastern Indonesia, such as in Papua, Maluku, and parts of Sulawesi. Communities in these regions rely on sago as their staple food in the form of papeda, sago porridge, and various processed products. Sago not only meets their carbohydrate needs but is also an integral part of local culture and traditions (BPS).

In the past, sago played a crucial role in ensuring food security in areas unsuitable for rice cultivation. The widespread consumption of sago during the pre-rice era demonstrates that sago is a reliable and adaptive food source for local conditions. Sago is also easy to process and store, making it a stable and long-lasting food source.

Opportunities and Challenges

Despite its potential, the utilization of sago in Indonesia still faces several challenges. One of the challenges is the lack of infrastructure and technology for sago processing. Many farmers still use traditional methods that are less efficient, so there is a need for technology transfer and capacity building to optimize sago production.

Additionally, there is a need for more aggressive promotion to raise public awareness of the benefits of sago as an alternative food source. Diversification of sago products and innovation in its processing can also open new market opportunities, both domestically and for export.

Conclusion

Sago is a natural resource with significant potential to be developed as a climate-friendly food source in Indonesia. With its ecological advantages and economic benefits, the development of the sago industry can support national food security while contributing to climate change mitigation efforts. Through appropriate investments in technology, infrastructure, and capacity building, sago can become a sustainable solution for Indonesia’s food future.
