Abstract: Gelatin berasal dari protein kolagen yang diperoleh melalui hidrolisis kolagen kulit dan tulang hewan yang dapat dimanfaatkan sebagai bahan baku pembuatan kapsul keras. Penelitian dilakukan untuk mendapatkan formula proses pembuatan gelatin optimal dari kulit ikan patin dengan Response Surface Methodology (RSM) serta dilakukan analisis fisik dan kimia kapsul keras gelatin. Rancangan eksperimen yang digunakan yaitu Central Composite Design (CCD) yang terdiri dari dua variabel yaitu volume asam sitrat (300 mL, 400 mL dan 500 mL) dan waktu perendaman asam sitrat (6 jam, 12 jam dan 18 jam) pada suhu ekstraksi 65°C selama 8 jam dengan delapan respon yaitu rendemen, kadar air, kadar abu, pH, kekuatan gel, viskositas, setting point dan melting point. Ekstraksi gelatin optimal pada perlakuan volume 500 mL dan waktu perendaman 18 jam menghasilkan gelatin dengan kualitas yang telah sesuai standar GMIA 2019 dan SNI 86222018. Nilai validasi keadaan optimal yang diperoleh yaitu rendemen 22,41±0,20% kadar air 6,72±0,40%; kadar abu 0,30±0,05%; pH 5,26±0,02; kekuatan gel 266,08±14,68 bloom; viskositas 59±0,16 mps; setting point 20,33±1,5°C; dan melting point 24,67±1,52°C. Karakteristik kapsul keras yang dihasilkan telah sesuai dengan standar Depkes RI 1995.
Gelatin is derived from collagen protein obtained through hydrolysis of animal skin and bone collagen which can be used as raw material for making hard capsules. The research was conducted to obtain the optimal formula for the process of making gelatin from catfish skin with Response Surface Methodology (RSM) and physical and chemical analysis of hard gelatin capsules were carried out. The experimental design was the Central Composite Design (CCD) which consisted of two variables, namely the volume of citric acid (300 mL, 400 mL and 500 mL) and the immersion time of citric acid (6 hours, 12 hours and 18 hours) at an extraction temperature of 65°C for 8 hours with eight responses, namely yield, water content, ash content, pH, gel strength, viscosity, setting point and melting point. Optimal gelatin extraction at treatment volume of 500 mL and soaking time of 18 hours produced gelatin with quality that complies with GMIA 2019 and SNI 8622-2018 standards. The optimal validation value obtained was yield of 22,41±0,20% water content 6,72±0,40%; ash content 0,30±0,05%; pH 5,26±0,02; gel strength 266,08±14,68 bloom; viscosity 59±0,16 mps; setting point 20,33±1,5°C; and a melting point of 24,67±1,52°C. The characteristics of the hard capsules produced are in accordance with the 1995 Ministry of Health standards.
