Environmentally friendly batik cleaner from sapindus mukorossi using taguchi method

The paper considers the making of an optimum and environmentally friendly batik cleaner from Sapindus mukorossi (Lerak) by means of Taguchi method. The result shows that Taguchi method effectively reduces the number of required experiments required to find the optimum composition of the components. In addition, optimum control factors of a more environmentally friendly batik cleaner are obtained by using the extraction of Sapindus mukorossi fruit without treatment, at 85°C for 50 minutes with ratio 1:10 in water. However, regarding to the acidic level, the acidic resulted from the liquid waste of the optimum batik cleaner has satisfied the allowable value but it has to be improved to be more environmentally friendly. Analysis on the saponin level shows that the obtained crude saponin of the optimum cleaner is 2.233% and known as triterpenoid saponin.
