Abstract:
Composite is a material that is formed from two or more materials with different properties,
so that a material with different properties and characteristics is produced. Composite
consists of reinforcement and a matrix. In this study, hydroxyapatite was acted as a matrix
and the reinforcement was derived from gelatin. The purpose of this study was to synthesize
hydroxyapatite-gelatin composites using the microwave method with prekursor (NH4)2HPO4
dan Ca(OH)2 precursors and also the adsorption test on methylene blue. The results of the
analysis of the chemical composition of the shellfish contained CaO (97.368%). Based on
the results of adsorption of methylene blue using hydroxyapatite-gelatin composites,
the optimum conditions for each of the adsorbent mass variations were obtained,
at K-HAp / Gel 0% was 10 mg (60.612%); K-HAp / Gel 10% is 5 mg (76.593%); K-HAp /
Gel 20% is 10 mg (77.110%) while for K-HAp / Gel 30% is 25 mg (79.903%).
