The research was aimed to determine the chemical and antimicrobial characteristics of the microparticle kinang extract using ultrasonication on various temperature and time ultrasonication process. This study uses a randomized factorial completely design with two treatment. The measuring parameters was consisted of chemical properties (antioxidant activity, total phenol, moisture content and pH value) and antimicrobial analysis (antibacterial activity). The results showed that time of ultrasonication treatment had significant effect on antioxidant activity, total phenol, antibacterial activity, moisture content and pH value. And temperature of ultrasonication treatment had significant effect on total phenol, antibacterial activity, moisture content and pH value. The interaction between time of ultrasonication and temperature of ultrasonication had significant effect on antibacterial activity, moisture content and pH value.
