Abstract
Kapok leaf contain many active compounds include saponins, flavonoids and phenols. The compounds
has broad uses, as detergents, forming foam in fire extinguishers and shampoo industries, having
hemolysis activity, and as the compounds used to remove kidney stones. The research aims to find out the
influence of extraction temperature and ratio of kapok leaf with solvent to the concentration, and
calculate the mass transfer coefficient (Kc). The extraction process was done using kapok leaf powder
extracted with ethanol as a solvent in a three-neck flask with a mixer on the extraction temperature, the
ratio of leaf with a solvent, and a particular time. To determine the concentration of extract in the
solution, the extract was analyzed using a UV- Vis spectrophotometer. Mass transfer coefficient values
obtained by optimization of the concentration of extract data at various times. From the results of
research on the optimum extraction temperature of 70° C on the ratio of kapok leaf with solvent of
5g/350 ml is obtained extract 0.62% of the weight of the leaf and mass transfer coefficient (Kc)
