Abstract

This study aims to determine the effect of pre-mordant material on kenaf fiber coloring using secang wood and teak leaves, to determine the Henodic Test method in classifying its quality, as well as to determine the significant effect on the color of kenaf fiber, and to determine the level of consumer preference for kenaf fiber. natural dyes. The research method used was an experiment with a variety of pre-mordant materials (alum, lime, vinegar). From the test, it was found that the color direction of the kenaf fiber was reddish purple to light brown, so the average value of fastness to washing was 4 (good). From this activity, it was concluded that the addition of secang wood and teak leaves as pre- mordant materials coupled with the effect of pH on the staining of kenaf fibers with secang wood extract provided variations in the direction of color and the value of color fastness to washing. Kenaf fiber is an environmentally friendly alternative to textile raw materials. This study used the Hedonic Test method with the Kruskal Wallis test. The results of this study were that there was no significant effect on the combination of compost application and pesticide application with natural dyes of secang wood and teak leaves on the color of kenaf fibers and there was no effect on the level of consumer preference for kenaf fiber with natural dyes.

Abstract

Secang wood (Caesalpinia sappan) and teak leaf (Tectona grandis L) were used to colour organic kenaf fibers with highly intense colours. This study aims to determine or analyze the level of absorption of secang wood dyes and teak leaves on organic kenaf fibres. The method used is maceration extraction with 60% ethanol and aquades as solvents. The extracted dye was heated at various temperatures (40°C, 55°C, 70°C, dan 80°C) to get the best conditions. The measurement of dye absorption was carried out using the UV-Vis Spectrophotometry method with a maximum wavelength (λ) of 446 nm. The data obtained are represented in the form of delta absorbance and percent absorption. The results showed that the maximum absorption of secang wood dye was 0.031 at a heating temperature of 55°C using 60% ethanol as solvent, while the maximum absorption of teak leaf dye was 0.092 at a heating temperature of 40°C using 60% ethanol as solvent. Secang wood dye was extracted at a heating temperature of 70°C by using distilled water produced a maximum absorbance of 0.82, and teak leaf dye extracted at a temperature of 70°C by using distilled water produced a maximum absorbance of 0.422. Based on the t test, it was found that there was no significant effect in determining the adsorption capacity and the percentage absorption of the dyestuffs of secang wood and young teak leaves because the polarity of the solvent used was not much different, so that the dye did not change significantly at different temperatures.
