Abstract
The use of synthetic dyes can cause health and environmental problems. Therefore it is necessary to explore various potential sources of natural dyes from fresh and fallen leaves of various plants. This study aimed to examine the influence of plant various and leaves types to the brightness color (L) and various color (a value and b value) of color produced on various fixation materials. Natural dyes were extracted using a heating method with a water solvent. Natural dye sources were taken from glodogan tiang (Polyathea longifolia) leaves, teak (Tectona grandis L. F) leaves, angsana (Pterocarpus indicus) leaves, and mango (Mangifera indica) leaves. The types of leaves were fresh and fallen leaves. Furthermore the natural dye was immersed in a cotton cloth and fixed using tunjung. Test on dyeing cloth used color difference test (L * a * b) and preference test. For determining the weight of interests of batik quality assessment parameter used the Analytical Hierarchy Process. Then to choose the best treatment was used alternative chosen with counted of expectation value. The results of the study shown that the best treatment was batik with natural dyes from fallen leaves of teak.
