The Influence of Storage on Structural Damage of Vegetable-Tanned Goat Skin by Microbes

This study aimed to determine the influence of storage on the structural damage of vegetable-tanned goat skin by microbes. The storage time was divided into three treatments, namely treatment P0 (0 months, storage), treatment P1 (6 months, storage), and treatment P2 (12 months, storage). The observation parameters for investigation included microbe contamination, pH levels, and levels of oil/fat. This study was conducted with Analysis Variance Completely Randomized Design (ANOVA) and Duncan Multiple Range Test (DMRT) to determine the differences between treatments. In contrast, analysis regression was used to obtain the optimum level. The research found that the highest amount of microbial contamination on the leather occurred at month 12, with the amount of microbial contamination reaching 4.46x103 CFU. The best storage for pH levels occurred at month 14 and pH 5.16. The skin with the best oil content is in the third month, with an oil/fat content of 7.97%.
