Abstract

The microwave-assisted extraction method for extraction of natural dyes from plants is more effective than the conventional methods because of shorter processing time and less solvents use. The objective of this research is to optimize the effects of extraction time, microwave power and feed/solvent (F/S) ratio on yields of microwave-assisted extraction using Response Surface Methodology to obtain conditions optimal operation through a Face-centered Composite Design (FCCD). The Face-Centered Composite Design was carried out to minimize the number of experiments. The results showed that the maximum yield of the extraction using FCCD design are microwave power of 600 W, F/S ratio of 0.0564 g/mL and an extraction time of 50 minutes is 3.5747%. And the p-value of model and lack of fit are significant and not significant, respectively. Thus, the selected model can be used to represent the results of experiments of natural dye extraction using microwave-assisted extraction method. In addition, microwave-assisted extraction method has been proven effective in producing natural dyes with a relatively higher yield and in a shorter time.
