Abstrak/Abstract Raw skin is the common primary material that used in the leather tannery. As an organic material, leather has a risk of microstructure damage from microorganisms. Although the tannery process uses several chemicals and actions to prevent its damage, the long storage time of leather can provide opportunities for microorganisms to regrow. The study aims to know the monitor lizard leather quality through the microstructure condition caused by microorganisms’ activity. The various storage time (1, 2, 3 and 4 years) of leather were evaluated by bacterial count. Based on the results, bacterial count and nitrogen content in the leather increased significantly (P<0.05), while the pH value and thermal stability decreased significantly after leather storage for two years. So, the longer the storage time, the lower the quality of the leather.
