Palm oil boiler fly ash and waste aluminum cans are abundant industrial residues that remain underutilized. This study aims to synthesize Y-type zeolite from boiler fly ash and aluminum can waste for application as an adsorbent to reduce nickel (Ni²⁺) content in industrial wastewater. The experiment employed variations in aluminum can mass (1 g, 2 g, 3 g) and boiler fly ash mass (60 g, 80 g, 100 g). Zeolite synthesis and its adsorption performance were evaluated in two stages. The obtained zeolite was characterized using FTIR and XRD to confirm Y-type zeolite formation, while AAS analysis determined nickel concentration. The optimal adsorption efficiency of 87.69% was achieved with 2 g aluminum can waste and 80 g boiler fly ash. These findings demonstrate that combining fly ash and aluminum waste can effectively produce zeolite Y with high potential as a sustainable adsorbent for heavy metal removal from wastewater.References
