Abstract
Sintesis ZSM-5 berbahan dasar kaolin Bangka sebagai sumber silika dan alumina dengan menggunakan TPABr sebagai templat organik telah dipelajari. ZSM-5 disintesis untuk membandingkan pengaruh waktu aging 6, 12, dan 24 jam menggunakan metode hidrotermal pada suhu 175°C dengan variasi waktu kristalisasi 12, 24, 36, dan 48 jam. Komposisi molar yang digunakan untuk sintesis ZSM-5 pada penelitian ini adalah 10Na2O : 100SiO2 : 2Al2O3 : 1800H2O : 20TPABr. Padatan hasil sintesis dikarakterisasi menggunakan teknik difraksi sinar-X (XRD), spektroskopi inframerah (FTIR), dan SEM-EDX yang menunjukkan bahwa ZSM-5 telah terbentuk saat waktu kristalisasi 12 jam pada semua variasi waktu aging. ZSM-5 dengan kristalinitas tertinggi didapatkan pada waktu aging 12 jam dengan waktu kristalisasi 36 jam. Kristalinitas semakin meningkat seiring dengan bertambahnya waktu aging namun ukuran partikel dan rasio Si/Al semakin menurun.

Synthesis of ZSM-5 from kaolin Bangka as silica and alumina sources with TPABr as organic template had been studied. ZSM-5 was synthesized to compare the effect of aging time 6, 12, and 24 hours using hydrothermal method in 175°C with variation of cristallization time 12, 24, 36, and 48 hours. Molar compotition that used for ZSM-5 synthesis in this research were 10Na2O : 100SiO2 : 2Al2O3 : 1800H2O : 20TPABr. The solid result were analyzed using X-ray diffraction (XRD), infrared spectroscopy (FTIR), and SEM-EDX which showed that ZSM-5 had been formed at the time 12 hours of crystallization by all variation of aging time. ZSM-5 with the highest crystallinity was produced using 12 hours of aging and 36 hours of crystallization. Cristallinity increased along with increasing aging time but the partical size and ratio of Si/Al decreased.
