Curcumin can form strong coloured chelates with transition metal ions. In this study, nine samples are prepared and different temperature and ratio. The samples are prepared at room temperature (25°C), 40°C and 60°C. Meanwhile, at different ratio of copper(II) : curcumin, the sample is prepared at 1:1, 1:1.5 and 1:2. The objective of this study are to find out the best ratio and temperature of preparation of Cu(II) -curcumin complex. The samples are prepared by reflux technique and characterized by using UV-VIS Spectrometer, Fluorescence Spectrometer, FTIR, and TGA/DTG. From this study, it showed that sample with ratio of 1:2 at room temperature is the best condition in order to synthesize Cu(II)-curcumin complex. It is recommended that this study is continued by preparing the samples at room temperature and replace ratio of copper complex from 1:1.5 to 1:3. Besides, for the complete characterization of metal complexes, it was recommended that to use X-ray structure analysis. Other than that, for better preparation of copper(II)-curcumin complex, copper chloride was not recommended be used but replace it with copper acetate.
