The purpose of this study was to evaluate antimicrobial and antioxidant of medicinal plants in the villages of Kwau
and Siau (Phytochemical, antioxidant, anti-bacterial, antifungal, and toxicity). The bark, roots, and leaves are
extracted with methanol to get the extract. Antimicrobial activity against Propionibacterium acnes, Escherichia coli,
Streptococcus sobrinus, and Candida albicans was determined by a good diffusion method. The DPPH radical
scavenging activity mechanism assayed antioxidant activity. Antimicrobial activity against the bacteria and fungi was
determined by the agar well diffusion method. Antioxidant activity was tested by DPPH radical rinsing activity
mechanism. Toxicity was determined by the Brine Shrimp Lethality Test method. The results showed that methanol
extract showed good activity against acne in only 8 of 13 species, ten species of 13 species for E.colii, three species of
13 species for S. sobrinus and, ten species of 13 species for C. albican at 25-500 ppm of extract tested. The toxicity
test showed that 0% of the deaths from Artemia salina Leach shrimp indicated that the absence of harmful compounds
was toxic in the sample, meaning that it was very safe to be consumed directly by humans, except for the roots of
Spondias cytherea Senn and the bark of Inocarpus fragiferua Fosk
