ABSTRACT

The purpose of the study was to obtain eco-friendly soaking process for goatskin and to shorten the soaking time. The enzyme used in the soaking process was Bacillus megatorium DSM-319, with enzyme concentration of 0.5, 1, and 1.5% and soaking time of 1, 1.5, and 2 hours. Each sample were tested for skin histology observation using photomicrograph, protein concentration analysis, tensile strength, elongation, colour fastness (dry and wet) and flexibility. The results showed that protein content of goat skin was decreased 42.32% after optimum soaking with 1% enzyme for one hour. The results of the physical testing of jacket leather with optimum soaking process met the quality requirements of SNI 4593:2011 Sheep/goat jacket leather.
