In Indonesia, coconut fiber (or coir) cultivation is an integral part of coconut farming, utilizing the husk of the coconut, which is traditionally a byproduct. Regions like Sumatra, Java, and Sulawesi have large coconut plantations where mature coconuts are harvested and processed to separate the husk from the fruit. The husks are soaked, retted, and mechanically or manually processed to extract long, durable coir fibers. These fibers are then dried, cleaned, and prepared for use in various products, including mats, ropes, brushes, and eco-friendly geotextiles. With a growing global focus on sustainable materials, Indonesia’s coconut fiber industry is expanding, providing environmentally friendly alternatives to synthetic products while supporting local economies and reducing agricultural waste.
