Abstract

This study aims to develop the anodizing method as an alternative approach in electrochemistry laboratory instruction. The research was conducted in the chemistry and physics laboratories of Universitas Negeri Jakarta from July 2023 to January 2024. The methodology employed in this study involves laboratory experiments using glassware and SEM-EDS to analyze the morphology of metals. Green chemistry-based anodizing practices were conducted by creating electrolyte concentrations of up to 15% and testing tea extracts as environmentally friendly dyes. The experimental results indicated that, out of 10 trials, both Aluminum and Titanium metals were successfully anodized in the electrolytic anodization process, and the tea extract dye was able to adhere to Aluminum through to the sealing stage.
