The application of chromium combination tanning system on red snapper (Lutjanus sp.) fish skin for women shoe upper has been done. Red Snapper fish skin is a waste from snapper fillet industry that can be used as raw material for leather tanning industry. It has unique, attractive, and exotic nerf/grain that makes it possible to be made into crafts and women shoes. This study aimed to determine the optimum combination of chromium, vegetable, and glutaraldehyde tanning agent for women shoe upper. There were 3 variations of tanning combination, namely chromium-chromium, chromium-glutaraldehyde, and chromium-mimosa. Mechanical properties, ecolabel parameters, identification of functional groups, surface morphology characterization, and distribution of elements in red snapper tanned leather were tested. The test results showed that chromium-mimosa combination tanning system was the optimum formulation for women shoe upper leather. All variations in tanning met the requirements of ecolabel criteria SNI 19-7188.3. 1-2006.
