This study aims to characterize the charcoal from the fins waste of the Kerandang fish, namely from the dorsal (DF), pectoral (PF), ventral (VF), anal (AF), and caudal fin (CF). The charcoal as a source of hydroxyapatite. Qualitative characterization used a Scanning Electron Microscope (SEM), Fourier Transfer Infra-Red (FTIR), and X-Ray Diffraction (XRD). The charcoal’s chemical composition consists of Carbon, Oxygen, Sodium, Magnesium, Phosphor, Sulfur, and Chlorine, Potassium, and Calcium. The highest carbon element was 67.74% in the caudal fins. The lowest chemical element in the element sulfur is 0.197% in the dorsal fins. SEM photos show that the charcoal from the caudal fins has more pores than the other fins. The FTIR results show that the functional groups contained in the charcoal from the fins are NH, OH, CO, C=O, C=C, S1-O, and CH groups, with wave numbers 1032-1036 cm −1 . The absorption area of the S1-O group (silica), where the silica group from charcoal, has the highest intensity. XRD results showed that the charcoal from fish fins of Kerandang contained 100% hydroxyapatite.
