Perbedaan jenis bahan penyamak terhadap sifat fisik kulit katak bull frog

The Obyective of this research is to study the effects of various tanning agents on the qualities of leather made from Bull Frog skin. Fifteen pieces of wet salted Bull Frog from Malang were tanned with several tanning agents, wich are mineral (10% Chromosal B), vegetable (10% Mimosa extract) and synthetic tensile strengths and elongations. Its turned out that vegetable tanning agent gave the higest tensile strength (279,62 kg/cm2), while mineral tanning agent gave the lowest one (183.04 kg/cm2). It showed that the type of tanning agent used significantly effects the tensile strength of the leather produced (p ≤ 0.005). On the other hand, mineral tanning agent gave the higest elongation (105.20%). While vegetable tanning agent gave the lowest one (91.20%). This result implied that the type of tanning agent used has a significant effect on the elongation (p ≤ 0.01).
