The purpose of this study was to synthesize bio-ceramics hydroxyapatite (HAp) from local chicken eggshell and broiler chicken eggshell. The synthesis was done by using precipitation method with sintering temperature 1000ºC. In addition, to determine the levels of calcium-phosphate contained in HAp bioceramics AAS and Spectrophotometer UV-Vis were used. The results show that of 10 grams of each eggshell powder can produce 8.8-9.8 g of HAp powder. Determination of calcium level in HAp by AAS was about ± 71.23% from local chicken eggshell and ± 78.62% from broiler chicken eggshell. Whereas determination of phosphate level in HAp using Spectrophotometer UV-Vis was about ± 67.22% from local chicken and ± 73.75% from broiler chicken eggshell.
