The synthesis of SZr-SBA-15 catalsyt was prepared by using urea hydrolisis method. SBA-15 incoporated with sulfated zirconia was prepared by reacting SBA-15 with Zirkoniumoxychloride and urea at 90oC to form ZrO2-SBA-15. Then H2SO4 was added to ZrO2-SBA-15 at room temperature to form SZr-SBA-15. This SZr-SBA-15 catalyst was used to synthesize biolubricant oil via esterification of oleic acid with TMP. The catalyst were characterized in terms of adsorption-desorption nitrogen analysis, SEM-EDX, FTIR and biolubricant oil was characterized by FTIR analysis. Based on SEM-EDX and adsorption-desorption nitrogen analysis result, it was found that Zr had been incorporate in SBA-15. The SZr-SBA-15 catalyst was an efficient solid catalyst for esterification of oleic acid with TMP with high conversion (85,9%) and selektivity (63,7%) to Trimethylolpropanetrioleat. From the study of reusability, it was found that SZr-SBA-15 catalyst could be used up to 3 rounds reaction without significant decrease in activity.
