    Fly ash is one of the organic wastes that has the potential as a base material for zeolite synthesis. Utilization of palm ash as a basic material for making zeolite is very potential considering its availability is quite large and sustainable. The purpose of this study was to determine the character of zeolite A as a result of synthesis by using a variation of the Si/Al ratio and the adsorption test for copper(II) ions. The synthesis of this zeolite uses the alkaline hydrothermal fusion method, with variations in the Si/Al ratio of 1.25; 1,5 and 2. Zeolite A synthesized was applied as an adsorbent in adsorbing copper(II) metal ions. The synthesized zeolite was characterized using FTIR, which showed that the zeolite has the O-T-O functional group, double ring and T-O asymmetric strain. The synthesized zeolite was then tested for its adsorption on copper(II) metal ions with time variation and characterized using AAS. Adsorptivity results show that the efficiency increases with the length of contact time. The average adsorption efficiency obtained is 86.97%. Based on these results, it can be concluded that zeolite A synthesized from oil palm shell fly ash has the potential as an adsorbent in adsorbing copper (II) ions..
