The production of hydroxyapatite (HA) from bovine bone has been carried out, to which alumina (Al2O3) and ortho resin will be added to form HA-alumina composites. The aim of this research is to obtain HA-Alumina composites which can be used as artificial implants. Bovine bone waste was synthesized by mechanical thermal. Its charaterization was performed by means of X-Ray Fluorescene (XRF) for ratio (Ca:P) analysis, Scanning Electron Microscopy (SEM) for microstructure, X-Ray Diffraction (XRD) to analyze the crystals of HA, Electron Diffraction X-Ray (EDX) was utilized to measure the composition of HA-alumina composites. The mechanical method with calcination at a temperature of 800oC was conducted on bovine bones to obtain HA. The HA-alumina composite was continued with the addition of 0%, 15%, 25%, and 50% of the total weight of alumina by adding resin as a binder. Analysis with SEM showed irregular round grains with an average size of 42.25μm. The obtained XRF analysis result was a Ca/P ratio of 1.61. The hardness and tensile strength of the composite increased and the percentage of agglomeration area decreased as the alumina composition was added. The addition of 50% alumina resulted in maximum hardness and tensile strength values of 124.8 HB and 86.56 MPa. The addition of alumina increased the mechanical properties of hardness and tensile strength. Hence, HA-Alumina composites could be used as artificial bone implants.
