Crystalline hydroxyapatite (HA) prepared from duck eggshell using the precipitation method. Duck eggshell used because it has higher calcium oxide (CaO) purity than another eggshell. The amount of duck eggshell calcinated to obtain calcium precursor then dropped with phosphoric acid wisely. The hydroxyapatite result modified with a silver (HA-Ag) using gamma radiolysis reduction. Hydroxyapatite powder added with an alcoholic silver ion precursor and followed by high energy gamma irradiation. This modification is to increase the antibacterial activity of hydroxyapatite for further medical applications. The results of the bacterial inhibitory test, showed the largest antibacterial clear zone in 25 kGy irradiation dose of HA-Ag. HA and HA-Ag characterized by FTIR, XRD, SEM and EDX. All characterization result support the forming of pure hydroxyapatite and the presence of a silver particle.
