An evaluation has been done on the properties of lambskin leather. The lambskin leather was originated from lambs fed with feedstuff contained a combination of Napier grass (Pennisetum purpureum) and agricultural wastes, as the main ingredient. The study evaluated 24 wet-salted lamb skins derived from lambs which fed by a combination of feedstuffs as the treatment. Experimental design was applied in this research with a completely randomized design. Treatments in the study involved the feeding of lambs with Napier grass (P0), Napier grass and corn cobs (P1), Napier grass and bagasse (P2), and Napier grass and peanut shells (P3), while the replication for each treatment were six. The raw lamb skins, flayed from the carcass and salt-preserved, were processed into crust leather with chrome tanning method. The evaluation of lambskin leather emphasized on the softness, tensile strength, elongation at break, tear strength, shrinkage percentage, and water vapor permeability. The result showed that the resulted leather had softness value in the range of 5.79±0.47 mm to 5.96±0.31 mm. All treatments resulted the leather in a good thermal stability with shrinkage percentage 16.44±1.32%, at maximum. Further, water vapor permeability of the lambskin leather was 14.21±0.85 – 17.29±1.47 mg/cm2.jam. In term of mechanical properties, the leather with treatment P2 promoted higher tensile strength (1661.19±116.34 N/cm2) than other treatments. Meanwhile, treatment P3 resulted leather with the highest value of elongation at break (104.42±6.69%) and tear strength (189.87±4.98 N/cm). Overall evaluation proposes a conclusion that most of treatments support the resulted lambskin leather to meet the requirement of leather for jacket in SNI 4593:2011. [ABSTRACT FROM AUTHOR] |
