Temulawak (Curcuma xanthorrhiza roxb) is a medicinal plant of the Zingiberaceae family. It grows in Indonesia and is used as a raw material for Indonesian traditional medicine. Temulawak is known to have many benefits, including being a potential antioxidant. The active component that is responsible for antioxidant activity in temulawak is curcumin. This study aims to analyze the potential of temulawak rhizome as an antioxidant. The raw materials used were obtained from temulawak rhizome farmers in Purworejo, Central Java. Extraction was performed using the liquid-liquid extraction method developed by PT Javaplant. Proximate analysis was performed and the antioxidant properties and curcumin level were measured. The antioxidant properties were measured using the DPPH method, whereas curcumin levels were measured using HPLC. The data obtained were processed and analyzed using SPSS and presented in the descriptive form. The curcumin and yield contents of the sample were 27.19 and 1.02%, respectively. The antioxidant capacity of temulawak (IC50) was 87.01 ppm. The Temulawak extract exhibited antioxidant activity that was classified as active and is therefore considered to be a good natural antioxidant.
