Abstract

In Indonesia, the leather tanning industries have already used big number of raw materials from land animal skins and hides like goats, sheep, cows, buffaloes and reptiles; while they use only a little number of raw materials from fish skin. The use of fish skin as alternative raw material is due to the limited supply of land animal skins and hides. Leather tanning mechanism is basically to put certain substances into the skin fibers. The purpose of this study is to look at the histological structure of puffer fish skins, from the raw and preserved skins until the tanned leather; and then to look at the physical strength, including tensile strength, elongation, tear strength, and sewing strength. This study uses 21 pieces of puffer fish skins consisting of raw and preserved skins, including salted, pickled and formalin. The experiment was done towards vegetable tanned leather, wet blue and formalin tanned leather; each with three-time repetition. To analyze the data, this research uses ANOVA and if there is a difference, the data will be further analyzed using Post Hoc Test. Based on the research result, there is no difference of the skin groups in tear strength. From histological structure, there is no difference between raw and preserved skins, but there is difference in tanning results. Nevertheless, pufferfish skin can still be used as alternative raw material for tanning. From physical tests, including tensile strength, elongation, tear strength and sewing strength, pufferfish skin can be used as raw material for leather products.
