Vegetable Tanning Process Of Starry Trigger Fish (Abalistes Stellaris) And Its Plotting To Leather Products

Abstract

The aim of this study was to obtain a optimum concentration of vegetable tanning agent which good for starry trigger fish tanning process, to find out the characteristic of the starry trigger fish leather and to make a plotting of their leather products. The process was done by using three vegetable tanning agents, those were mimosa, quebracho and chestnut. Concentrations of the each tanning agents were varied to 12%, 15% and 18%. The physical characterization of the leather products were tested by using Universal Testing Machine (UTM). The results showed that the highest tensile strength, elongation and tear strength achieved by 18% concentration of each tanning agents. The plotting of leather products for the tanned starry trigger fish skin based on its physical characteristics were leather goods and leather crafts products.
