The antioxidant activity was determined using the DPPH method measured by&nbsp; UV-Vis spectrophotometer and the IC<sub>50</sub>value was determined. While the antibacterial activity of AgNPs was determined by the inhibitory zone diameter of <em>Stap</em><em>h</em><em>ylococcus aureus</em>. The result of this research showed that AgNps biosynthesised from 70% and 96% ethanol extract of <em>Carica papaya L.</em> leaf able to inhibit the free radicals of DPPH with IC<sub>50</sub> values of 1415.12 µg/mL and 1351.22 µg/mL respectively. While, both 70% and 96% ethanol extract also inhibit the <em>Stap</em><em>h</em><em>ylococcus aureus</em> bacterial growth within 5.40 mm and 6.27 mm, respectively. To sum up, although the AgNPs produced have low antioxidant activity, both extracts have the bacterial activity of <em>Stap</em><em>h</em><em>ylococcus aureus</em>.</p> ER -
