Pemanfaatan limbah kulit ikan nila dari industri filet untuk kulit jaket

The research to reuse skin waste of the Nile tilapia sp resulted from the Fish's fillet industries was done to produce leather for garment by washable tanning process. Three variable concentrations of reactive dyes, hydrophobic fat liquoring agent and anionic water repellent were used in this research by 10, 15, and 20% for reactive dyes and 10, 12.5, and 15% for both hydrophobic fat liquoring agent and water repellent resulted twenty-seventh of treatment. The research result saw that there is no fade and no change in color after washing and have a good of persperation test for all the treatment, light fastness test resulted 5 of Grey Scale whereas sofness test resulted in range of scale 4 to 6. Tearing and sawing tests saw that for all treatment were fulfill the SNI 06-4593-1998, Garment leather from sheep and goat. Those were in range of 19.81 kg/cm to 47.70 kg/cm and 59.58 kg/cm to 98.57 kg/cm for tearing and sewing properties respectively. Whereas tensile properties saw that from the 27 treatment, 15 treatment were fulfill SNI requirement with the highest value was 171,40 kg/cm2 , for elongation properties for all treatment saw the result was runs between 69,30% and 110,00%. Optimal conditions resulted by concentration of 10% reactive dyes, 10% hydrophobic fat liquoring and 10% anionic waterrepellent.
