Abstract

Ketapang leaves contain tannin pigments of 11% -23% so that they can produce colors ranging from brownish yellow to dark brown. The purpose of this study was to determine how to process ketapang leaves into natural dyes for batik cloth and to determine the effect of dyeing frequency and type of mordant on color sharpness and color fastness. This study uses an experimental method, which is a method that is useful for finding the effect of certain treatments on the conditions to be controlled. The process starts from the selection of the extraction method, namely the reflux method, and the selection of the mordanting process, namely the provision of mordant at the end. The results showed that the effect of dyeing frequency and type of mordant on color sharpness using the L*, a*, b* color test was quite significant. The more the dyeing frequency, the darker the resulting color. The lowest L* value was 53.02 for lime mordant and 20.78 for tunjung mordant with 18 times of immersion frequency. The highest a* value was in lime mordant 12.15 with 18 times of immersion and 8.43 of tunjung mordant with 6 times of immersion. The highest b* value was 38.99 for lime mordant and 11.35 for tunjung mordant with 6 times of immersion frequency. The effect of the frequency of immersion and the type of mordant on the TLW test, namely washing soap and hot ironing dry did not have much significant effect. A good and optimal TLW value found in lime mordant and tunjung is 4 in the good category with 12 times the immersion frequency.

Abstract

One of the symbols that reflect Indonesian culture is batik. One of the processes of making batik is coloring. The use of traditional dyes is gradually being replaced by chemical dyes. However, chemical dyes can cause some environmental problems. To minimize the impact of environmental pollution, it is possible to reuse natural dyes. Papaya leaves were chosen because they can be used to produce non-food natural dyes by way of processing that is easier and more effective and is available in relatively large quantities. The chlorophyll content in papaya leaves is 13.91 mg/L after spinach leaves, kale leaves, and cassava leaves. Fixation agent is needed in the coloring process in order to suppress the color direction by changing the color intensity according to the type of mordant and variations in its concentration. This study used variations of alum and tunjung with concentrations of (35, 70, and 105) grams. The color quality is proven through the fabric color space test and the color fastness test to dry ironing heat and washing soap. The stages in this study were starting from material preparation, papaya leaf extraction, coloring, fixation, pelorodan, and testing the color space and color fastness. Based on the data obtained, it was concluded that the type and concentration of the optimal fixation agent in papaya leaf extract as a natural dye was the type of fixative agent of tunjung with a concentration of 105 grams.
