Abstract

This study aimed to determine the potential of Rhizophora mucronata, Maclura cochinchinensis, and Ceriops tagal extracts as a dye for ecoprinting leather. The parameters evaluated were color values (L*, a*, and b*), Fourier-Transform Infrared Spectroscopy (FTIR) analysis, and ecoprinting leather color fastness. The results showed that R. mucronata extract produced a brownish-red color with the L*, a*, and b* values of 17.53, 36.27, and 30.19, respectively. M. cochinchinensis extract produced a brownish-yellow color with the L*, a*, and b* values of 34.59, 31.87, and 58.61, while C. tagal extract produced a reddish-brown color with the L*, a*, and b* 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 R. mucronata and C. tagal extracts have a value of 4, indicating a good category. In contrast, M. cochinchinensis extract has a value of 5, with an excellent tegory. It showed that the extracts of R. mucronata, M. cochinchinensis, and C. tagal could be used for leather coloring with the ecoprinting method.
