The Barramundi fish skin is a by-product of the Barramundi fillet industry which can be used as a raw material for the leather tanning industry. The Barramundi fish skin has a unique and specific grain that can be used as raw material for crafts or shoes. This study aims to determine the optimum formulation of a combination of chromium, mimosa and glutaraldehyde tanning agents on physical and chemical properties, such as flexing resistance, tear strength, color fastness, lastability, seam strength, chromium VI, tensile strength and elongation to meet the requirements of womens shoes . The raw skin were tanned using chromium tanning agent and then neutralized and tanned using a variation of 2-4% chrome , 2% mimosa , and 2% glutaradehyde. The Barramundi fish leather were tested with ISO TR 20879: 2007 : Footwear - Performance requirements for components for footwear - Uppers. The results showed that all of formulations met the requirements of ISO TR 20879: 2007 except the flexing resistance test was mildly damaged. For shoe upper, The Baramundi fish leather can be strengthened by coating the bottom of the leather with other stronger materials. The optimum formulation are combination of chromium-chromium and and chromium-glutaraldehyde.
