        abstract = {Synthesis of NaZSM-5 and impregnation of K3PO4 catalyst with concentration 5, 10, and
15 wt.\% on the resulting NaZSM-5 as a catalyst to produce biodiesel have been done in
this study. 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{\ensuremath{\theta}} = 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.}
