Abstract
Penelitian ini bertujuan untuk mengetahui pengaruh variasi rasio mol Na2O/SiO2 terhadap sintesis zeolit Y melalui tahap metakaolinisasi. Sintesis zeolit Y dilakukan dengan metakaolin sebagai prekursor diikuti dengan komposisi variasi rasio mol Na2O/SiO2 4-10 Na2O : Al2O3 : 10 SiO2 : 180 H2O melalui proses pemeraman dan hidrotermal selama 24 jam pada suhu 100℃. Padatan hasil sintesis dikarakterisasi menggunakan difraksi sinar-X (XRD), spektroskopi inframerah (FTIR) dan Scanning Electron Microscopy Energy Dispersive X-Ray (SEM-EDX). Hasil karakterisasi dengan XRD dan spektroskopi inframerah menunjukkan fase zeolit Y terbentuk pada variasi rasio mol Na2O/SiO2 = 6 dan 8. Pada variasi rasio mol Na2O/SiO2 = 10 terbentuk fase sodalit. Hasil SEM-EDX menunjukkan morfologi hasil sintesis pada variasi rasio mol Na2O/SiO2 = 6 dan 8 menyerupai bentuk oktahedral dengan perbandingan rasio SiO2/Al2O3 sebesar 2,36; 2,78 dan 3,92.

The purpose of this research was studied the effect of variation Na2O/SiO2 mol ratio towards synthesis zeolite Y through metakaolinization. Synthesis of zeolite Y was done by metakaolin as precursor and variation of the mol ratio 4-10 Na2O : Al2O3 : 10 SiO2 : 180 H2O following by aging and hydrothermal process for 24 hours at 100℃. Solid products were characterized using infrared spectroscopy (FTIR), X-ray diffraction (XRD), Scanning Electron Microscopy-Energy Dispersive X-ray (SEM-EDX). The result of XRD difractometer showed zeolite Y was formed at Na2O/SiO2 = 6 and 8 mol ratio. Sodalit phase was formed on variation Na2O/SiO2 = 10 mol ratio. SEM micrograf showed that mol variation ratio Na2O/SiO2 = 6 and 8 approach octahedral form with ratio SiO2/Al2O3 2,36; 2,78 and 3,92.
