The objective of this research was to know the influence of reliming on physical properties of tanned stingray skin. The research used randomized completely block design with three treatments. The treatment consisted of: liming once (PI), liming twice (P2), and liming three times (P3). Quality parameters analyzed were tensile strength (%), elongation at break (kg/cm2), and skin suffocation organoleptically. The data were analyzed by analysis of variance methods and subsequently by Least Significant Differences Test, α. 0,05. The results showed that elongation at break tanned stingray skin of P1, P2, and P3 respectively were 26.5, 30.0, and 32.0%. Result analysis of tensile strength tanned stingray skin of treatment P1, P2, and P3 respectively were 238,04 ; 259,53 : and 270,89 kg/cm2. The result analysis of suffocation tanned stingray skin of treatment P1, P2, and P3 respectively were 1,78 ; 2,13 and 2,45. The P3 treatment effected the tanned stingray skin on the tensile strength, elongation at break and skin suffocation, and meet the requirement of SNI 06-6121-1999, about the quality criterion for stingray skin leather product.
