Taguchi method application to improve the quality of coffee pulp screen printing products

Abstract

One of the main reasons consumers choose a product is based on quality. Consumers will choose products that have the quality as expected and in accordance with the benefits obtained. This is the basis for conducting research on Coffee Pulp Screen Printing products. The study was conducted with the Taguchi Method to determine the optimal combination of color parameters produced by coffee pulp screen inks. The parameters studied were Coffee Pulp as a factor A, the amount of Water as a factor B, the amount of vinegar as factor C and the length of cooking time as a factor D. experiments were carried out with two levels and two values for each factor. In this experiment using orthogonal array L8 (27) with two replications. The results of the analysis were processed using S/N average and variability ratios. Based on the result of these experiments it was found that the factors that significantly influence the color quality of coffee plup screen printing ink are coffee plup 0,5 kg, o,5 liter water, 100 ml vinegar, and 15 minutes cooking time. The results of the experiment show the optimal combination to get a dense color on the results of coffee grounds.
