dc.description Rehabilitation and reposition of human fractured bones using metal implant have some unadvantages, i.e surgeon process has to be conducted at least 2 times that leads another physical injuries and traumatic problem to the patients. Moreover, mechanical and physical properties of metal pin are different to those of human bones. The usage of metal implant causes a stress shielding effect and allergic problems. The weakness of metal implant uses could be overcomed by using bioceramic base implant material. Bioceramic extracted from hard tissue of animal contains high quality hydroxyapatite in ultra refine size (nanometer scale) is potential to be proceed as implant or artificial bone that has physical and mechanical properties approaches natural human bones. One of sources for bioceramic is clamshell (Anadara Antiquata) that is largely wasted in Indonesia‟s beach. This work is aimed to characterize of bioceramic powder extracted from Clamshell through mechanical and heat treatments optimation for resulting new kind of local bioceramic. The clamshells used in this study were collected from Padang and Pariaman beaches. They were then processed into nanometer-sized powder by using ball mill processing. Ball milling was conducted at a speed of 100 rpm at the beginning and slowly raised to 200 rpm, for 60 minutes using ceramic and stainless steel balls. Clamshell powder was then heated in a heat treatment furnace at temperature of 800ᵒC in air. The obtained powder was then observed by using scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDX) and X-ray diffraction (XRD). The results showed that there is no significant effect of ball mill material on a grain fineness number of the powders, where the ceramic balls produce a grain fineness of #198, and stainless steel balls are #211. The treatments change the morphology of the powders from flakes into stickyglobular form. The content of calcium, Ca, (in weight percentage) increases significantly from 34.42% to 49.67%. While, the size of the crystals is the same using ceramic and stainless steel ball, that are 82 nm. The main compound phase changes from calcium carbonate into calcium hydroxide.
