Abstract

This study explores the use of natural dyes as an environmentally friendly alternative to synthetic dyes for coloring batik fabric. Specifically, the researchers focus on developing natural dyes from a combination of avocado leaves and soursop leaves. The study aims to determine the impact of extraction time and the ratio of avocado and soursop leaves on the color fastness of batik cloth. Experimental methods were employed, with two extraction times (120 and 240 minutes) and three ratios of raw materials (25%:25%, 15%:35%, and 35%:15%) tested. The results of the color fastness test, which assessed washing and rubbing, demonstrated that the mixture of avocado and soursop leaves exhibited good fastness and resistance to rubbing. These findings suggest that the extracted mixture could be used effectively as a natural dye for batik fabric. Overall, this study contributes to the development of eco-friendly alternatives for the dyeing process in batik production.

Abstract

Indonesia is one of the countries known for its various arts and cultures. One of them is batik, batik is one part of the archipelago's culture which has many motifs and patterns that are much favored by the people of Indonesia and abroad. Soursop (Annona murocata L.) is a plant that grows and bears fruit throughout the year. Soursop leaves have many health benefits, besides that the tannin content in soursop leaves can be used as a natural dye in batik cloth which can produce a reddish brown color. In this study using the experimental method using variations in concentration (40 and 80 grams) and type of fixation (lime, alum, and arbor). With the variation method that has been used, it turns out that it has an effect on the color produced. Good research results were obtained with a concentration variation of 80 grams using alum and arbor fixation substances.
