Pengaruh berbagai jenis penyamakan dan tipe finish terhadap morfologi, sifat organoleptis dan mekanis kulit biawak (Varanus salvator)

Monitor lizard (Varanus salvator) skin is exotic leather because it has a unique grain. Therefore, the original grain of the animal needs to be maintained in the finishing process so that its performances look likes natural. This research aimed to study the effect of tanning materials (vegetable and chrome) and the type of finish (natural, aniline, semi-aniline and two tone) on morphology, organoleptic and mechanical properties of lizard skin. The materials used in this study were dry preserved lizard skins. The research varied on the types of tanning (vegetable and chrome) and the type of finish (natural, aniline, semi-aniline and two tone) each by varying the finishing materials (casein and protein binders). The tests were conducted on the observation of the structure using photomicrographs, rub fastness, adhesion of finish strength, tensile strength, elongation at break and organoleptic. The results showed that the best result was vegetable tanned lizard skin using natural finish with casein and met the requirements of SNI 06-4362-1996, lizard skin for shoe upper. This gave dry and wet rub fastness of 5 and 5 respectively; dry and wet adhesion of finish strength of 650 and 100 g/cm respectively; tensile strength of 207.43 kg/cm2; elongation at break of 37.52% and organoleptic value of panelists observations of 87.9 (good).
