Abstract

Batik is an integral heritage of the Indonesian culture. With a variety of beauty, style and quality, natural colors and patterns of interest makes batik a very popular traditional cloth. Indonesia as one of the tropical country has great potential to produce healthy batik and friendly to the environment by utilizing various resources that available in nature. Efforts to produce environmentally-friendly batik can be done using colors derived from extracts of plant that contain flavonoide with attractive colors. Natural dyes for textile materials are generally obtained from the extracts of various parts of plant one of its is wood. Formulation of colouring material in an emulsion system that is ready to use is an attractive approach to encourage the use of natural colourant. In this research, colouring material was extracted using an organic solvent and emulsified in water with the aid of a surfactant. This research aimed to identify the characteristics of emulsion of tegeran wood extract. The concentration of mixture of tegeran wood extract and surfactant was varied (5, 10, 15 and 20% and the characterization included microscopic structures, colour intensity and viscosity. The research showed that viscosity increased with the increase in concentration of tegeran wood extract (ranged from 17,33 – 28,67 cp). Tegeran dyes emulsion with 3% tawas addition, analysis its size used to particle size analyzer for 5, 10, 15, 20, 25, and 30% concentration resulted 1,55, 2,2, 2,05, 2,6, 2,4 and 2,65 nano meter. Stability tend to decrease with the decrease in extract concentration, while intensity increase with the rise in extract concentration.
