Analog curcumin A-135 (2,5-bis(3-bromobenzylidene)-cyclohexanone) is one of the curcumin derivative compounds that has therapeutic potential in anti-tuberculosis treatment. In this study, the synthesis of compound A-135 was carried out using microwave irradiation and catalysts HCl, H?SO?, and H?PO?, as well as characterization and elucidation of the compound using various types of instruments. The research results showed that synthesis using H?SO? catalyst without solvent produced the highest yield, reaching 158.3% (1.848 g) of the theoretical mass in wet conditions and 51.4% (0.600 g) of the theoretical mass after drying. The melting point test results showed that using H?SO? + THF catalyst resulted in a melting point of 113.3°C – 113.9°C with a relatively narrow melting range, ?0.6°C, indicating the compound was relatively the purest compared to other catalyst selections.
