Kolagen memiliki aktivitas antioksidan dan mampu menghambat aktivitas tirosinase pada proses<br />melanogenesis, salah satu biota laut yang dapat dijadikan sumber kolagen alternatif adalah teripang.<br />Penelitian ini bertujuan menentukan karakteristik kolagen dan aktivitas penghambatan enzim tirosinase<br />oleh kolagen teripang emas (Stichopus hermanii). Penghilangan protein non kolagen dilakukan dengan<br />cara perendaman daging teripang menggunakan NaOH 0,1 M selama 48 jam. Isolasi kolagen dilakukan<br />menggunakan asam asetat 0.5 M selama 48 jam. Analisis gugus fungsi kolagen dilakukan menggunakan<br />FTIR dan analisis aktivitas tirosinase dilakukan menggunakan spektrofotometer. Kadar protein non<br />kolagen yang diperoleh yaitu 0,090 mg/mL dan kolagen teripang emas memiliki rendemen 0,66%. Kolagen<br />teripang memiliki nilai pH 6,91, gugus fungsi khas amida A (3379,29 cm-1), amida B (2924,09 cm-1), amida<br />I (1681,93 cm-1), amida II (1568,13 cm-1), dan amida III (1269,16 cm-1). Aktivitas penghambatan tirosinase<br />menunjukkan bahwa kolagen teripang emas memiliki nilai IC50 5610 ppm. Kolagen teripang emas belum<br />mampu menghambat aktivitas tirosinase.
