Tujuan penelitian ini adalah untuk memperoleh persentase dan pengaruh HCI pada proses penyamakan terhadap kualitas kulit ikan nila. Materi yang digunakan kulit ikan nila ( Oreochromis niloticus ) dari PT Nusantara Aquafarm, Semarang. Parameter pengujian adalah kekuatan tarik, kemuluran, kekuatan sobek, kadar krom oksida, pH, kadar air, dan uji hedonik. Penelitian ini menggunakan percobaan Rancangan Acak Lengkap (RAL) dengan tiga perlakuan yaitu HCI 2,5%, 3%, dan 3,5%. Data dianalisis menggunakan analisa sidik ragam (ANOVA). Hasil penelitian menunjukkan bahwa penggunaan HCI sebesar 2,5% berpengaruh nyata (P<0,05) terhadap kualitas kulit yaitu kekuatan tarik, kemuluran, kekuatan sobek, kadar krom oksida, pH, uji hedonik dan tidak berpengaruh nyata terhadap kualitas kimia kadar air. Kulit ikan nila samak dengan perlakuan konsentrasi HCI 2,5% memiliki kualitas yang baik yaitu, kekuatan tarik (2348,6 N/cm 2 ); kemuluran (23.63 %); kekuatan sobek (235,20 N/cm 2 ); kadar krom oksida (6,23%); pH(4,3); kadar air(17,63%); uji hedonik parameter serat daging (4,46); parameter kult (4,43); dan parameter sisik/ nerf (4,51).

The purpose of this study is to obtain the best percentage and the influence of the use of HCI in the tanning process on the quality of tilapia fish skin leather. The material used in this research was skin tilapia (Oreochromis niloticus) from PT Nusantara Aquafarm, Semarang.
