Seaweeds contain natural antioxidants, which are good for human health. The antioxidant activity of seaweed can vary due to their extraction methods, such as solvent type and raw material form. A marine alga Boergesenia forbesii is is abundantly found in Bengkulu but is underutilized. The purpose of this study was to assess the antioxidant activity of B. forbesii extract collected from Teluk Sepang Beach in Bengkulu. The sampling was done from November 2022 to January 2023. Fresh and dried B. forbesii were extracted using polar solvents (methanol and ethanol) and the antioxidant activity of each extract was determined using the DPPH method. The experiment was repeated three times. The highest yield was obtained from dried seaweed ethanol extract (1.87±0.31%). The IC50 of B. forbesii extracts is classified as an intermediate to weak antioxidant. Dried seaweed raw materials showed better antioxidant activity. Green seaweed B. forbesii methanol extract is potential to be use as a natural antioxidant.
