Peat swamp forests in Kalimantan have generally been damaged due to overexploitation and excessive human activities. Akar kuning plant (Fibraurea tinctoria Laur.) is known as a traditional herbal medicine used by Central Kalimantan people. This study aimed to obtain data on the potential, distribution, and association of akar kuning in the Block Release forest, Mantangai District, Kapuas Regency, Central Kalimantan Province. Data collection was conducted with an inventory purposive sampling method, where two transect lines were made and placed in the location where akar kuning was observed. Then 80 sampling units with a size of 5 m x 5 m and 2 m x 2 m were made alternately with an area of 0.2 ha. The results showed that the potential of Fibruarea tinctoria in the Block Release forest was 375 individuals/ha and 675 individuals/ha, where the seedling phase is more dominant than the sapling phase (40 individuals/ha and 70 individuals/ha). The akar kuning distribution pattern was also found to spread uniformly or regularly. The level of association measured using the Ochiai index (OI) indicated that the most significant value of association strength was owned by Shorea balangeran and Mangifera similis (OI = 0.63), while the presence of Freycinetia angustifolia had a low level of association (OI = 0.48 - 0.23). Meanwhile, the lowest level of association (OI = < 0.22) was found in 17 species. Plant species associated with Fibraurea tinctoria are usually having potential as medicinal raw materials. Information regarding population, distribution and distribution patterns, as well as the association of akar kuning, is expected to be the basis for sustainable management of akar kuning in nature.
