This study is an experimental study, the research stages include the synthesis and characterization NaZSM-5 and K3PO4/NaZSM-5. Characterization by X-Ray Diffraction (XRD) was conducted to determine the X-ray diffraction patterns and the percentage crystallinity of the samples. X-ray diffraction pattern of the resulting sample showed the emergence of diffraction peaks with high intensity at 2? = 7.8; 8.8; 23.0; 23.2, and 24.3° are specifically indexed to the structure of the MFI topology. The percentage crystallinity of the sample becomes smaller with increasing number of K3PO4 impregnated on NaZSM-5 synthesis. Characterization of the samples by Fourier Transform Infra Red (FTIR) aims to determine the type of functional groups present in a compound. FTIR spectra of samples NZ, NZK5, NZK10 and NZK15 have absorption bands in the region 1220 and 547 cm-1 which shows the absorption characteristics of vibration T - O - T on NaZSM-5 type zeolite which distinguish the other and sensitive to changes in structure. The results of characterization using XRD and FTIR showed that the structure of NaZSM-5 remained unchange after impregnated with K3PO4.
