    Abstract

    Hydroxyapatite is one of the most commonly used biomaterials in biomedical applications. Hydroxyapatite itself can be produced from cow bone (bovine) which is one of many materials we easily find and have the same structure with human bones. The objectives of this study were to find out the hardness, compressive strength, and density of bovine hydroxyapatite (BHA)/shellac/sorghum materials. Hydroxyapatite used from bovine bone, shellac as a binder, and sorghum flour to make porous. Bovine bone powder in calcined 700oC, then compacted with sorghum flour and shellac.After that, sintered in temperature 1000oC. Adding sorgum flour caused a decrease mechanical properties and increase the porosity. The result of highest hardness and compresive strenghts 59,10 HVN and 1,67 MPa with the density 1594 kg/m3 on variation of BHA/shellac/sorghum flour 90/10 %volume.While the lowest hardness and the compresive strenght is 12,7 HVN and 0,03 MPa with the density 1115 kg/m3 variation BHA/Shellac/sorghum flour 50/50 %volume.
