Hydroxyapatite is an inorganic compound consisting of calcium and phosphorus with the chemical formula Ca10(PO4)6(OH)2, which has great potential as a bone implant material. Its bioactive, biocompatible and osteoconductive properties make hydroxyapatite able to interact with bone tissue naturally. Gourami fish bone waste, which is rich in calcium oxide (CaO), can be used as an alternative source for hydroxyapatite production. This research utilizes the potential of gourami fish bone waste as raw material in the synthesis of hydroxyapatite for bone implant applications. CaO from gourami fish bones was isolated using the digestion method and then synthesized by adding 2 M phosphoric acid (H3PO4) stirred at a speed of 700 rpm at a temperature of 40oC for 1 hour. This research aims to determine the elemental composition, functional groups, compound phases and surface shape of the synthesized samples. The results of XRF analysis show a Ca/P ratio of 0.9 and the results of FTIR analysis indicate the presence of hydroxyl groups (OH), phosphate groups (PO4) and carbonates (CO3) which are functional groups of hydroxyapatites but based on the XRD diffraction pattern it shows that there is an angle difference of 2θ between gourami fish bone hydroxyapatite with the comparison hydroxyapatite. SEM analysis showed diverse particle distribution in the synthesized hydroxyapatite.
