| dc.description.abstract | Purun is a type of grass that has been widely used as the main raw material in
making woven handicrafts. Generally, purun woven products are colored using
synthetic dyes that can have negative impacts on the environment and health.
Considering the impacts caused by synthetic dyes, research is needed on natural
dyes for raw materials for purun woven crafts of the type purun danau (Lepironia
articulata). Ketapang leaves, angsana tree bark, and telang flowers have the
potential to be used as natural dyes. The purpose of this study was to compare the
results of natural dyes with 3 types of dye raw materials with synthetic dyes,
compare the color stability of purun dyed using natural dyes and synthetic dyes
after storage for two months using a colorimeter, its effect on the anatomical
structure and dimensions of purun fibers and their derivative values. Ketapang
leaves, angsana tree bark, and telang flowers as raw materials for natural dyes
were extracted by boiling extraction, resulting in 3 natural dye treatments that will
be tested on raw materials for purun danau woven. The results showed that the
color formula used affects the color results obtained. Several dye treatments
provide significant differences in the runkel number, muhlsteph ratio, stiffness
coefficient, and flexibility values of purun fiber. The relatively long purun fiber and
its high weaving strength value indicate that the use of purun by the community as
a raw material for crafts is appropriate, because it will produce high-quality
products. The colorimeter value of the green synthetic dye has the best color
stability with a ΔE value of 2,93. In contrast, the natural angsana dye experienced
the most drastic color change with a ΔE of 43,53. | en_US |
