Abstract

Pelaksanaan Tugas Akhir di CV Sari Banteng Mulya bertujuan untuk menemukan pemecahan masalah pada proses fatliquoring untuk perbaikan kualitas tear strength kulit domba golf glove pearl white dengan penambahan konsentrasi Peramit LSW New. Materi yang digunakan dalam pelaksanaan tugas akhir proses fatliquoring kulit domba golf glove pearl white adalah kulit domba wet blue dengan kualitas R sebanyak 5 lembar, tebal shaving 0,4-0,45 mm. The Final Task at CV Sari Banteng Mulya aims to find a solution to the problem of the fatliquoring process for the improvement of tear strength quality of golf glove pearl white sheepskin with the addition of the concentration of the Peramit LSW New. The material used in carrying out the final task of the golf glove pearl white sheepskin fatliquoring process was wet blue sheep skin with R quality of 5 pieces, shaving thickness of 0.4-0.45 mm. The auxiliary materials used in the fatliquoring process were Pelastol ET, Pellan 802, Pellan L-90, Peramit LSW New, and Peramit MLN. The method used in the fatliquoring process was a short float. The fatliquoring process was through 3 stages which were to determine the number of addition of Peramit LSW New, fatliquoring process with influential factors (effect of oil ratio and wet blue skin, oil concentration on penetration, emulsion process, RPM, and pH), testing the tear strength of golf glove pearl white sheep sheepskin with tensile strength tools. Data processing was done by the description method. The results of the final assignment obtained the concentration of Peramit LSW New of 2.5% in the fatliquoring process for improving the tear strength quality of golf glove pearl white sheepskin. The fatliquoring process with the addition of 2.5% Peramit LSW New was found to have the same process control, which was the short float method (50% of water), Peramit LSW New emulsion material, 60 minutes, and pH of 5.8. The results of the physical tests of tear strenght do not meet SNI standards but meet consumers’ organoleptic standards. The obtained value of the test of the tear strength is increased from 16.93 kg/cm to 31.2 kg/cm, with a rise of 14,27%. The SNI standard for golf glove sheepskin is 50 kg/cm. Peramit LSW New can improve the tear strength quality of glove skin so that it can be used as a raw material for golf glove pearl white.
