Corresponding Author: wibowo@student.ub.ac.id ABSTRACT This study aimed was to determine the optimal ratio, duration, and temperature reaction to form the astaxanthin- metal ions complex based on the UV-Vis spectrum profile and confirmation of complex formation using FTIR. The method used consists of the synthesis of the astaxanthin-metal ions (Cu2+ and Zn2+) and the determination of complex formation based on the UV-Vis spectrum profile which is evaluated at a wavelength of 190–790 nm. Then the selected complexes were analyzed for their functional groups using FTIR at wavenumbers of 400-4000 cm-1. Astaxanthin-metal ions complex was successfully synthesized and characterized by UV-Vis and FTIR. The optimal ratio, temperature, and stirrer time for astaxanthin-Cu2+ are (3:1), 78oC, and 5 minutes, while astaxanthin-Zn2+ is (1:1), 78oC, and 15 minutes, respectively.
