Zeolite Y has been synthesized from Kaolin Bangka Belitung as precursor through activation of metakaolin with acid. The synthesis of zeolite Y consist of metakaolinitation, activation metakaolin with sulfuric acid using various concentrations (3, 6, 9, 12, and 15 M), aging, hydrothermal process for 24 hours at 100 °C. The solid products were characterized with X-ray Diffraction (XRD), Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDX). The result of XRD and FTIR indicated that zeolite Y formed at the variations 3, 6, 9, 12, and 15M. Based on XRD pattern of the results, phase of zeolite P formed at the variation 3M. The surface morphology and ratio of Si/Al of Zeolite Y was analyzed using SEM-EDX. The SEM micrograph of zeolite Y and P with variation of sulfuric acid 3, 6, 9, 12, and 15M like octahedral and sphere form and the ratio of Si/Al of the products based on EDX are 1.7; 1.6; 1.58; 1.64; and 1.59 respectively.
