The zingiberene content was observed by using Liquid Chromatography-Mass Spectrofotometry and regarding to the independent variable of temperature, extraction time, ginger-solvent ratio and aging time. By applying subcritical water, the critical value of zingiberene content obtained was 0.036%. This value was approached by the surface modeling of alpha for rotatability design which performed at 125 C, 20 min of extraction time, 0.08 of ginger to solvent ratio and 9 min of aging time of extraction parameters. The surface modeling was validated by plotting the observed and predicted value of zingiberene content and evidenced by the value of R-square at 0.76.}, issn = {2684-8090}, pages = {18--21} doi = {10.14710/jvsar.v1i1.4292}, url = {https://ejournal2.undip.ac.id/index.php/jvsar/article/view/4292} }
