Abstract
abstrak
Batik is a product of Indonesian culture which contains various philosophical values in every motif/ornament on every piece of cloth. The growth and development of batik continues to experience a good increase in every region in Indonesia, this is proven by the increasing number of new types of motifs and their local cultural significance. There are two types of batik cloth dyeing process, namely natural and synthetic colors. With the development of time, dyeing batik cloth with natural dyes has become increasingly popular as an environmentally friendly alternative to synthetic dyes. This research aims to compare the results of natural colors produced from mahogany skin using water from two different locations, namely Karimunjawa Island and Jepara. The material used as natural color uses mahogany trees, especially the bark which contains tannin, extracted using water from each location, then used to color mori cloth through the mordanting and dyeing process.
The research results show that water characteristics, such as pH, mineralization and ion content, have a significant effect on the intensity and stability of the color produced. Color measurements are carried out using a spectrophotometer to obtain quantitative data, as well as visual evaluation for qualitative observations. Data analysis shows a real difference in coloring results between water from Karimunjawa Island and Jepara, where water from Jepara produces more intense and brighter colors. This is indicated by a higher mineral content and a more optimal pH for tannin extraction.
This research provides new insight into the influence of water quality on natural dyeing results, and offers alternative dyes that are more environmentally friendly and sustainable in making batik. It is hoped that the results of this research can support the preservation of traditional dyeing techniques, tridharma of higher education and the development of a more environmentally conscious batik industry.
