dc.description.abstractZinc Oxide (ZnO) nanoparticles are inorganic semiconductors that are generally powdered and non-toxic and have high electron mobility and thermal stability. This research aims to synthesize ZnO nanoparticles using Ketapang leaf extract for use in methylene blue photocatalysts. The method used in this study is Biosynthesis using Ketapang leaf extract. Ketapang leaf extract contains flavonoid compounds and tannins that function as corrosion inhibitors in metals. Ketapang leaf extract is made with a ratio of 1: 5, temperature 60°C and pH 12. The success of the reduction reaction is depicted from the UV-Vis spectrophotometer the emergence of absorption at a wavelength of 381.17 nm and an absorbance of 1.3879 a.u. ZnO nanoparticle powder successfully degraded methylene blue by 25 ppm with an efficiency of 59.8% at 1 hour and 72.4% at 2 hours.en_US
