Aims: This study aimed to obtain the skin extract of Phaleria macrocarpa (Scheff.) Boerl. through the application of ultrasound-assisted extraction (UAE) with variations in time and amplitude to produce optimal extraction conditions. The extract{\textquoteright}s potential as an antioxidant with 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical inhibition parameters, and its potential as an anti-gout. Results: The yield of crude ethanol extract of Phaleria macrocarpa (Scheff.) Boerl rind obtained from the UAE process ranged from 18 to 21\%. The phytochemical test results of Phaleria macrocarpa fruit peel extract contain phenolic compounds, tannins, saponins, and alkaloids. Extract B was treated for 35 minutes and had an amplitude of 65\% with an antioxidant activity IC50 of 52.01 {\textpm} 0.06 mg/L and a reduction of uric acid level of 90.49 {\textpm} 0.08. Conclusion: The ethanol extract of the fruit peel of Phaleria macrocarpa from the UAE has the potential as a source of antioxidants and anti-gout.
