      Abstract
      Sisik merupakan salah satu limbah hasil samping perikanan yang dapat digunakan sebagai bahan baku alternatif pembuatan gelatin. Gelatin adalah produk turunan protein yang dihasilkan melalui degradasi kolagen. Perlakuan yang digunakan dalam penelitian ini adalah pengunaan sisik ikan yang berbeda, yaitu sisik ikan nila (Oreochromis niloticus), sisik ikan gurami (Osphronemus goramy), serta sisik campuran ikan nila dan gurami. Analisis statistik yang digunakan adalah analisis ANOVA dan uji lanjut Duncan. Kualitas gelatin terbaik diperoleh dari jenis sisik campuran ikan gurami dan ikan nila. Rendemen yang dihasilkan dari gelatin sisik ikan tersebut yaitu 14,45±0,28%; kadar air 11,04±0,18%; kadar abu 0,49±0,25%; kekuatan gel 208,29±2,6 bloom; viskositas 7,26±0,02 mPas; setting point 18,60±1,90ºC; dan pH 7,11±0,06. Gelatin sisik ikan gurami, sisik ikan nila serta sisik campuran ikan gurami dan ikan nila menunjukkan rantai ß, a1, a2 dan hasil FTIR menunjukkan gugus fungsi khas gelatin yaitu amida A, amida I, amida II dan amida III.
       
      Scales are a by-product of fisheries that can be used as an alternative raw material for making gelatin. Gelatin is a protein derivative product produced through collagen degradation. This research aims to determine the influence of different types of fish scale raw materials. The treatments used in this study were the use of different fish scales, namely tilapia fish scales (Oreochromis niloticus), gourami fish scales (Osphronemus goramy) and mixed scales of tilapia fish and gourami fish. The statistical analysis used was ANOVA analysis and Duncan's post-hoc test. The best quality gelatin is obtained from mixed types of gourami and tilapia fish scales. The yield produced from fish scale gelatin was 14.45±0.28%; water content 11.04±0.18%; ash content 0.49±0.25%; gel strength 208.29±2.6 bloom; viscosity 7,26±0,02 mPas; setting point 18.60±1.90ºC; and pH 7.11±0.06. The gelatin of gourami fish scales, tilapia fish scales and mixed scales of gourami fish and tilapia fish shows ß, a1, a2 chains and FTIR results show the typical functional groups of gelatin, namely amide A, amide I, amide II and amide III.
