Freshwater mussel (Pilsbryoconcha sp.) shells have a proportion of 51.93%, which is included in the solid waste resulting from the processing of mussels. In fact, mussel shells are rich in minerals, especially high calcium, with a calcium content of 39.55%. So innovation is needed so that the utilization of mussel shells is maximized. One way is through the valorization of mussel shells into products with high added value. This study aimed to determine the physicochemical characteristics of the CaO (calcium oxide) extract of freshwater mussel shells. Valorization of mussel shells into calcium oxide (CaO) flour by calcination method at 1000°C temperature. The test parameters were yield, functional groups using the FTIR instrument, macro (calcium, potassium, magnesium, phosphorus) and micro minerals (Manganese, zinc, iron, and sodium) using the AAS instrument. The results showed that the physicochemical characteristics of calcium oxide (CaO) flour from the shell of the freshwater mussel (Pilsbryoconcha sp.) included: the proportion of shell 51.90%, the proportion of meat and viscera 48.10%; CaO yield of 56.47%; identified the Ca-O group at a wavelength of 1 661, 1 409, 1 116, and 875 cm-1; and dominated by calcium content of 76.27% to potential as a calcium precursor in the synthesis of hydroxyapatite.
