Waste from the food industry can be utilized to meet the nutritional needs of ruminant animal feed. One of these industrial wastes that can be utilized is soybean husk. Soybean epidermis can be used to meet the protein needs of ruminant animal feed, because it contains protein residues from soybean seeds. However, the sensitivity of soybean epidermis is very low, so efforts are needed to improve the quality of soybean epidermis as a source of feed protein, namely through the fermentation method. The purpose of this study was to evaluate the level of addition of EM4 on the physical quality of soybean epidermis fermentation. The materials used in this study were soybean epidermis and EM4 (starter). The research tools are pH meters, measuring cups, spoons, plastic and buckets. This study used a completely randomized design (CRD) with different levels of EM-4, namely 0 CC, 1 CC, 2 CC and 3 CC. While the research method used was laboratory experimental using a Completely Randomized Design (CRD) with 4 treatments and 5 replications. This research was conducted to determine the physical quality which includes odor, color, texture, temperature, pH, water content, alcohol content, salt content, and sugar content. The data obtained was then processed using ANOVA. The results showed that the treatment changed the color to brown, the smell/aroma was sour and smelled of ammonia, the texture of the soybean epidermis was softened, and there was no fungal growth. From changes in physical quality it can be concluded that treatment can improve the physical quality of soybean epidermis.
