This study is aimed at detecring of physical properties (tensile strength and elongation) of balida fosh skin lather (Natopterus chitala sp). Material used in this study is nfive sides from Pontianak (West Kalimantan). They were then tracted with Chromosal B as tanning agent and Irgata I.V as retanning agent to be finitshed leather. On testing the finished leather it is found that there is not aby significant different betweeb the dry and salted balida fish skin leather on their fisical properties of tensile strength and clongation, the mean of tensile streght of dry preserved balida skin lather and salied balida akin leather of which respect tively are 226,82 kg/cm2 and 43,2% respecrively. Viewed from thye test result, it is obviously that balida skin leather to be used material pf leather goods.
