Abstract
Natural dyes are alternatives to synthetic dyes as batik dyes. However, color results produced by natural
dyes were not as good as synthetic dyes, hence mordant compounds were required. As a substitute for
metal mordant, it was essential to have another alternative mordant, such as chitosan. This research was
intended to analyze the color produced by various sources of natural dyes, betel nut; spurred mangrove
(tingi) bark; baheda (jolawe) peel; mangrove bark; mahogany bark; and copperpod (jambal) bark,
quantitatively by testing the value of color differences (ΔE) on variations of the chitosan concentration
and fabric dyeing. In conclusion, the use of chitosan could enhance the absorption of dye into the fabric.
In a chitosan concentration of 10 g/L, betel nut reached an ΔE value at 15.40; spurred mangrove 16.26;
baheda peel 18.97; mangrove 10.87; mahogany 14.01; and copperpod 19.33. Furthermore, the test of
fastness to sunlight with greyscale showed the value in range of 4-5 (good).
