Abstract
ABSTRACT. Mangrove stem (Rhizopora mucronata) contains a tannin compound which has potential as tanning material as well as tanner leather coloring. Meanwhile, the public uses more tannin from mimosa tannin and has not optimized the use of mangrove tannins. This study aimed to determine the quality of rabbit hide tanned from mangrove tannin and mimosa tannin. The material used was Rex rabbit hide of 1-year age cut. The research method used a completely random design (CRD) experiment. The treatment ratio of mangrove stem tannin and tannin mimosa concentration were 0:30%, 10:20%, 20:10% and 30%:0. The parameters measured by chemical properties consist of: degree of tanning, moisture, ash and tannin bound to the skin. Physical properties consisted of: tensile strength, elongation and sewing strength. The results showed that the use of mangrove tannin and mimosa tannin for tanning ratios had no significant effect (P> 0.05) on the level of tanning, moisture, ash, and tannin that were bound to tanned skin, tensile strength, elongation and sewing strength. The results showed that the quality of tanned hide had a tanning degree of 62.31%, 13.32% moisture content, 1.57% ash content, and 25.14% tannin content. The physical quality of tensile strength was 356.35 N/cm, elongation was 29.80% and sewing strength is 84.41 Kg/cm. The results of the quality of this tanned hide had fulfilled SNI 06-6121-1999 of leather goods. The conclusion was that tannin extract from mangroves can be used as vegetable tanning agent, with the same quality as mimosa tanning agent.
