SWEET POTATO (Ipomoea batatas L.) BASED MICROBIAL CELLULOSE AS ADVANCED BIOMATERIAL FOR SUSTAINABLE LEATHER PRODUCTION

Bio cellulose, Ipomoea batatas, Cilembu, leather, microbe, sustainable materialAbstract
The increasing global market’s need for leather is not matched by sufficient production. Furthermore, leather production itself has negative impacts on the environment. An alternative for leather products is needed in order to establish sustainable leather production. The aim of this research is to provide meaningful information to better understand the potency of Cilembu microbial cellulose as a sustainable alternative to leather. Indonesian sweet potato, Ipomoea batatas ‘Cilembu’ is used as a raw material to make microbial cellulose. Various concentrations (100 g/L, 150 g/L, 250 g/L, and 500 g/L) were used in this research. The cellulose thickness and dry weight were measured in various Cilembu sweet potato concentrations and the microstructure was analyzed using scanning electron microscopy to give insightful information about this biomaterial product. The results show that the culture medium with 500 g/L Cilembu sweet potato concentration gives the best result (13 mm thickness and 0.24 g dry weight) among the other treatments. The microstructure shows that different concentrations of the Cilembu medium can form the same microstructure of microbial cellulose fibers as tea medium. The size of the cord’s cellulose is approximately 25-100 nm.
