Abstract
The purpose of the study was to determine the physical appearance and identify the functional groups contained in hydroxyapatite nano calcium flour from calcined and non-calcined catfish bones. Experimental method. Stages : Making fish bone calcium nano flour - Identification of functional groups of catfish bone calcium nano flour using Fourier Transform Infrared Spectroscopy (FTIR). The results of the research: visually the calcium nano flour was not calcined, it was bone white while the calcined was white. The results showed that non-calcined catfish bone calcium nano flour was identified as having CO32-, PO43- and no hydroxyl (OH) groups identified, while calcined catfish bone calcium nano flour contained CO32-, PO43- and (OH) groups as hydroxyapatite components. This indicates that catfish bone meal contains hydroxyapatite. It is hoped that as a source of scientific information, catfish bone meal contains hydroxyapatite as an alternative to natural calcium
