[ABSTRAK
Hibrida zeolit ZSM-5 dan SOD telah berhasil dibuat di atas permukaan glassy carbon. Pertama?tama zeolit ZSM-5 disintesis dari koloid gel ZSM-5 dengan
menggunakan dua jenis template atau yang dikenal dengan sintesis double
template dan metode hidrotermal. Selanjutnya zeolit SOD dilapisi di atas
permukaan ZSM-5 dengan menggunakan metode seeding menggunakan koloid
gel seed dan larutan prekursor. Hasil XRD menunjukkan bahwa zeolit yang
dihasilkan merupakan zeolit ZSM-5 dan SOD. Diperkuat dengan hasil SEM dan
EDS yang memperlihatkan rasio Si/Al pada ZSM-5 sebesar 2,5 dan pada SOD
sebesar 1,3. Untuk melihat pengaruh gas amonia terhadap hibrida zeolit dihitung
menggunakan alat impedance analyzer yang dapat dilihat pada frekuensi sebesar
20 Hz ? 20 kHz didapat rentang deteksi dari 0 ppm ? 100 ppm serta dihitung
hubungan antara konsentrasi dengan perubahan nilai impedansi pada frekuensi
100 Hz dan diperoleh nilai r2 sebesar 0,9376.
ABSTRACT
Hybrid zeolite ZSM-5 and SOD have been successfully fabricated on the surface
of glassy carbon. First,zeolite ZSM-5 synthesized from colloidal gels ZSM-5 by
using two types of templates, known as double-template synthesis and
hydrothermal method. Furthermore, SOD zeolite coated on the surface of ZSM-5
by using a seeding method using seed and colloidal gel precursor solution. XRD
results showed that zeolite ZSM-5 and SOD has been obtained. Reinforced with
SEM and EDS results showing the ratio of Si / Al in the ZSM-5 at 2.5 and the
SOD of 1.3. To see the effect of the hybrid zeolite ammonia gas is calculated
using the impedance analyzer tool which can be seen at a frequency of 20 Hz until
20 kHz obtained the detection range of 0 ppm until 100 ppm and calculated the
relation between the concentration of the change in value of the impedance at a
frequency of 100 Hz and obtained values of r2 of 0.9376., Hybrid zeolite ZSM-5 and SOD have been successfully fabricated on the surface
