Pankreas kambing mengandung enzim proteolitik yang berpotensi sebagai bating agent dalam proses penyamakan kulit.Tujuan penelitian ini adalah mengetahui pengaruh penggunaan bating agent dari pankreas kambing terhadap karakteristik fisik kulit ikan nila tersamak dan mengetahui konsentrasi terbaik dari penggunaan bating agent pankreas kambing. Materi yang digunakan dalam penelitian ini adalah kulit ikan niladan pankreas kambing segar. Metode penelitian ini bersifat experimental laboratories menggunakan Rancangan Acak Lengkap (RAL) dengan tiga kali pengulangan dengan 4 konsentrasi bating agent yaitu (0,5%, 1%, 1,5% dan 2%) kulit ikan tersamak diuji dengankekuatan tarik, kemuluran, kekuatan sobek, kadar krom oksida, dan suhu kerut. Hasil penelitian menghasilkan bahan bating agent berpengaruh terhadap karakteristik kulit ikan tersamak (P<0,05). Konsentrasi bating agent sebesar 2% memberikan hasil yang terbaik sebagai berikut: kekuatan tarik 1300,45 N/cm², kemuluran 87,70%, kekuatan sobek 273,90 N/cm², kadar krom oksida 3,46 %, dan suhu kerut 99,75°C. Kulit ikan nila tersamak hasil penelitian semua perlakuan memenuhi persyaratan SNI 06-4586-1998 kecuali untuk parameter kemuluran tidak memenuhi syarat. Goat pancreas, containing proteolytic enzymes which the potential as a bating agent in the process of tanning the skin. The purpose of this study was to determine the effect of using bating agent from goat pancreas on the physical characteristics of tilapia skin and knowing the best concentration of using the goat pancreatic agent. The material used in this study is the skin of tilapia and fresh goat pancreas. This research method is experimental laboratories using Completely Randomized Design (CRD) with three repetitions with 4 concentrations of bating agent namely (0.5%, 1%, 1.5% and 2%) the skin of tanned fish is tested with tensile strength, elongation, tear strength, chrome oxide content, and wrinkle temperature. The results of the study resulted in bating agent material affecting the characteristics of tanned fish skin (P <0.05). Bating agent concentration of 2% gave the best results as follows: tensile strength 1300.45 N / cm², elongation 87.70%, tear strength 273.90 N / cm², chrome oxide content 3.46%, and wrinkle temperature 99, 75 ° C. The results of this study produced a total nitrogen of 2.65% of the goat pancreas which has great potential to be used as bating material. The skin of tanned tilapia from the results of this study meets the requirements of SNI 06-4586-1998 except for elongation parameters that do not meet the requirements.
