The purpose of this study was to develop environmentally friendly black dye by comparing Ketapang and Gallnut, that have been traditionally used as a black dye. As a result of FT-IR and UV-Vis spectrophotometer analysis, Ketapang was characterized by condensed tannin, while Gallnut showed hydrolyzable tannin. Due to the dyeability characteristic analysis, the color fastness of the non-mordant dye was slightly lowered to grades 1-3. In the dry-cleaning fastness test, both non-mordant and iron mordant were excellent, in grade 4-5, and the daylight fastness was excellent grade 3-5 too. The L* values of Ketapang were 26.93 (pre-mordant) and 29.39 (post-mordant), which were higher than those of Gallnut, 41.90 (pre-mordant) and 43.02 (post-mordant), indicating that Ketapang was more easily colored as a black dye than Gallnut.
