PEMANFAATAN LIMBAH CANGKANG TELUR AYAM DAN BEBEK SEBAGAI SUMBER KALSIUM UNTUK SINTESIS MINERAL TULANG THE USE OF HEN'S AND DUCK'S EGGSHELL AS CALSIUM SOURCE TO SYNTHESIS BONE MINERAL

This study aimed to develop bone substituted biomaterial consisting of inorganic mineral (apatit) and organic material as matrix. In this study, a precipitation method of apatite-chitosan composite synthesis has been used using hen’s and duck’s eggshell as calcium source and synthetic KH 2 PO 4 as phosphate source. The eggshell and KH 2 PO 4 act as inorganic mineral, whereas organic matrix used was chitosan originated from shrimp shell. The eggshell was calcinated to decompose all the carbonate (CO 3 ) phases. To produce the composite, calcium phosphates were grown on organic matrix of chitosan using ex situ method. The result samples were further dried at 50 o C. Characteristic of the samples were performed using X-ray Diffraction (XRD) and Fourier Transform Infrared (FTIR) Spectroscopy. The XRD profile illustrated specific diffraction angles at peaks of apatite crystals. This data were supported by FTIR spectra that showed transmittance peak of phosphates and carbonates from apatites.
