The Influence of Tanning Material Difference on the Physical Quality of the Skin of Puffer Fish (Arothon reticularis)

Abstract

The aim of study was to investigate the in uence of tanning material difference on the physical quality of the skin of puffer sh (Arothon reticularis) in relation with the usage of Natural Resources, particularly shes, i.e. puffer sh skin. Puffer shes are famous for being toxic, very dangerous and have many bones in the skin, which is being its characteristic and speci cation. To make the bone not too sharp, two types of tanning are performed, i.e. chrome and vegetable tanning. To discover any tensile strength and elongation difference between vegetable skins and chrome skins, independent t test was performed. The result of the test |t count| of tensile strength = 3.511, and elongation 6.098 > t table (0.05:16) = 2.119 or by comparing signi cance value which is bigger than error level (0.05) it was concluded that there was tensile strength difference between vegetable skins and chrome skins, and there was elongation difference between vegetable skin and chrome skins.
