Abstract:	The research of rhodamine B dye biosorption by Red Snapperâ€™s scale (Lutjanus argentimaculatus) powder has been done. The red snapperâ€™s scales were cleansed with aquades and dried. The dried red snapperâ€™s scales were grinded and sieved to powder with a 100 mesh sieve. The powder of red snapperâ€™s scale was dried at 100 Â° C in oven for an hour. The biosorption process toward rhodamine B dye and its results were examined with UV-Vis spectrophotometer. The optimum condition of red snapperâ€™s scale powder for 1.0 g of absorbent has biosorption capacity in amount of 92.740%; the optimum contact time is 120 minutes with biosorption capacity in amount of 97.264%; for 50 ppm biosorption concentration has biosorption capacity in amount of 95.598% and the optimum pH of 3 has biosorption capacity of 97.930%.
