The parameters evaluated were color values (<em>L<sup>*</sup>, a<sup>*</sup></em><em>, </em>and <em>b<sup>*</sup></em>), Fourier-Transform Infrared Spectroscopy (FTIR) analysis, and ecoprinting leather color fastness. The results showed that <em>R</em><em>. mucronata</em> extract produced a brownish-red color with the <em>L<sup>*</sup>, a<sup>*</sup>, </em>and <em>b<sup>*</sup></em> values of 17.53, 36.27, and 30.19, respectively. <em>M. cochinchinensis</em> extract produced a brownish-yellow color with the <em>L<sup>*</sup>, a<sup>*</sup>, </em>and <em>b<sup>*</sup></em> values of 34.59, 31.87, and 58.61, while <em>C. tagal</em> extract produced a reddish-brown color with the <em>L<sup>*</sup>, a<sup>*</sup>, </em>and <em>b<sup>*</sup></em> values of 32.36, 36.80, and 34.06. The results of FTIR analysis of the three mangrove extracts identified several functional groups such as O-H stretch, C=O stretch, C=C aromatic, C-O-C stretch, and C-N stretch. The color fastness of wet rubbing showed that <em>R</em><em>. mucronata</em> and <em>C. tagal</em> extracts have a value of 4, indicating a good category. In contrast, <em>M. cochinchinensis</em> extract has a value of 5, with an excellent tegory. It showed that the extracts of <em>R. mucronata</em>, <em>M. cochinchinensis</em>, and <em>C. tagal</em> could be used for leather coloring with the ecoprinting method.</p> <p>Keywords: <em>Ceriops tagal</em>, ecoprinting leather, <em>Maclura cochinchinensis</em>, natural dyes, <em>Rhizophora mucronata</em></p>}, number={1}, journal={Jurnal Sylva Lestari}, author={Pancapalaga, Wehandaka and Ishartati, Erny and Ambarwati, Titik}, year={2023}, month={Jan.}, pages={98–106} }
