Abstract
This study investigates the photoactive potential of bio-activated rice husk ash (RHA) as a semiconductor using analytical methods for CuO and SiO2 extraction prediction. The study focuses on the enhancement of photoactive characteristics in RHA through bioactivation, utilizing pineapple peel juice as a natural activator. Analytical method based on UV-Vis spectroscopy peak frequency of RHA, sunked (SCNM), and floated (FCNM) products were utilized to determine CuO and SiO2 extraction potential. W...
