%X Preparation of Ni/bentonite acid activated using a reducing agent from dragon  fruit peel extract (Hylocereus polyrhizus) and its application in the synthesis of one  pot system menthol from citronellal has been carried out. The aims of this study  were to characterize acid-activated Ni/Bentonite using reducing agents of dragon  fruit peel extract based on FTIR spectrophotometry and X-ray diffraction  characterization based on XRD diffractograms and to analyze the product produced  in the synthesis of one pot system menthol from citronellal using acid-activated  Ni/bentonite catalyst.  The catalyst of Ni/Bentonite acid activated was synthesized by the wet  impregnation method with the addition of dragon fruit peel extract as a natural  reducing agent. Acid-activated Ni/Bentonite was successfully synthesized based on  the help of the FTIR spectrum with absorption at wavelengths of 1049.28 cm-1 and  694.37 cm-1 which indicated the Si-O group in bentonite and the XRD  diffractogram indicated the presence of Ni at the absorption peak of 2
