PENYAMAKAN KULIT IKAN NILA (Oreochromis sp.) DENGAN PERLAKUAN PEMUCATAN (BLEACHING) MENGGUNAKAN PEROKSIDA
Abstract: Research for tanning
fish skin nile (Oreochromis sp.) on bleaching treatment has been done.
Concentration of peroxide as bleaching agent variated in 2, 4, and 6% (v/w) and
non bleaching process as a control. As a nile Leather product research
characterized trough physic parameter, chemical and organoleptic analysis.
Result of nile leather product the optimal amount of peroxide was 4% which
resulted in tensile strength of 205 kg/cm2, elongation of 84,67%, sewing
strength of 117,29%, and rigid temperature of 84oC. Chemical properties for the
4% peroxide were 14.99% of water content, 1.65% of chrome content, 2.25% of ash
content, and 12.90% of lipid content. Sensory analysis shows that nile leather
in the same variable (4% peroxide) has smooth surface that most panelist
valuated and it has scale tissue unique motif, shinning surface, elastic, soft,
and meatless. The colour of scale tissue was a soft dark, but the most of
panelist choose nile fi sh leather with 6% peroxide bleaching treatment.
