Ekstraksi dari Serbuk Kayu dan Kulit Kayu Malaka (Phyllanthus emblica L.) sebagai Zat Warna Alami

Abstract

This research was motivated by the lack of exploration of the abundance of tree species in Indonesia that have the potential to become natural dyes and the impact of synthetic dyes that can interfere with health in the form of cancer threats, so researchers chose malacca wood and malacca bark (Phyllanthus emblica L.) as a source of natural dyes. And evaluate its potential to be applied in the textile industry. The research methods used in this study include extraction method and dyeing method. The results showed that malacca produces dark brown color for skin and light brown for wood. Substances from malacca leather and wood also showed good color stability against washing 80 times, the color difference value (ΔE) was in the very small to medium category. Where in the ecoprint technique the old skin has a fastness value of 4.37, young skin 2.79, old wood 2.23, young wood 2.73 and in the dyeing technique the old skin 3.88, young skin 3.18, old wood 1.85, young wood 1.89. The interaction between stem part and plant age was not significantly different (p>0.05) to the fading value and color produced. Malacca wood and bark have high antioxidant values ranging from 55.71% to 78.67% in extracts, 76.61% to 95.38% in fabrics with dyeing techniques and 43.09% to 54.94% in fabrics with ecoprint techniques. Fabrics treated with dyes from malacca extract also had antibacterial inhibition ranging from 10.74% to 23.15% for S.aureus bacteria and 3.33% to 8.33% for P.acnes bacteria. Malacca extract has bacterial inhibition values that range from 22.22% to 44.44% for S.aureus bacteria and 16.67% to 27.78% for P.acnes bacteria. Based on the test results, malacca bark and wood have promising prospects as a source of environmentally friendly natural dyes.
