Description
Summary:Clove ( Syzygium aromaticum ) leaves are agricultural waste of clove plants which can still be valorised by extracting their essential oil. The the aim of this research is to perform the extraction process of clove essential oil using Solvent free microwave extraction by studying the effects of extraction parameters, such as microwave power, feed to distiller ratio and extraction time and finding optimal conditions with the response surface methodology using FCCD design. The operating parameters of this experiments are microwave power (300 -600 W), feed to distiller ratio (0.06 - 0.14 g/mL), and extraction time (20 - 60 minutes). The existence of analysis of variance values (ANOVA) which indicates an important factor that determines the results of the study. From the analysis results obtained 4 parameters that have a significant effect (p-value
