Abstract:
Composite is a material that is formed from two or more combination materials with the
result that it is resulted a composite material that has different mechanical and
characteristic properties from the forming material. The purpose of this research is to
conduct hydroxyapatite synthesis from lokan shells (Geloina coaxans) using the
method of microwave with Diammonium hydrogen phosphate (NH4)2HPO4 precursor
and Ca(OH)2 and for adsorption of hydroxyapatite/chitosan as adsorben toward
methylene blue. Hydroxyapatite/chitosan (HAp-C) synthesis result of is characterized
X-Ray Floresence (XRF) contain is CaO 98,759 %, used to adsorb methylene blue with
an adsorption ability of 71,1296 %
