Abstract
Sintesis zeolit Y dari kaolin Bangka Belitung sebagai
sumber silika dan alumina telah dipelajari. Zeolit Y disintesis
menggunakan metode hidrotermal untuk mengetahui pengaruh
rasio mol SiO2/Al2O3 (x) = 4, 5, 6, dan 7. Pada penelitian ini, zeolit
Y disintesis dengan komposisi rasio mol pada seed gel
10,67Na2O:xSiO2:1Al2O3:180H2O dan komposisi rasio mol pada
feedstock gel 4,3Na2O:xSiO2:1Al2O3:180H2O menggunakan
metode hidrotermal pada suhu 105 °C. Hasil padatan
dikarakterisasi menggunakan teknik difraksi sinar-X (XRD) dan
spektroskopi inframerah (FTIR) yang menunjukkan bahwa zeolit
Y mulai terbentuk pada sampel dengan rasio mol SiO2/Al2O3 4 dan
waktu hidrotermal 12 jam. Berdasarkan hasil XRD yang diperoleh,
sampel dengan rasio mol SiO2/Al2O3 4 dan 5 menghasilkan
intensitas partikel fasa zeolit Y yang tinggi dan intensitas partikel
fasa gismondin yang rendah.

Synthesis of zeolite Y from kaolin Bangka Belitung as a
source of silica and alumina has been studied. Zeolite Y has been
carried out by hydrotermal method to determine the effect of
variation molar composition of SiO2/Al2O3 (x) = 4, 5, 6, and 7 on
the synthesis of zeolite Y. In this research, zeolite Y synthesized
with ratio mol composition on seed gel
10,67Na2O:xSiO2:1Al2O3:180H2O and on feedstock gel
4,3Na2O:xSiO2:1Al2O3:180H2O using hydrothermal method in 105
°C temperature. The solid results were analyzed using X-ray
diffraction (XRD) and infrared spectroscopy (FTIR) showed that
zeolite Y began to form on the sample at the molar composition of
SiO2/Al2O3 = 4 and the time 12 hours of hydrotermal. Based on the
intensity obtained, the sample with the ratio mol composition of
SiO2/Al2O3 4 and 5 produced high particle intensity of zeolite Y
phase and low particle intensity of gismondine phase.
