The precipitation method successfully synthesized cockle shells into a highly valuable biomaterial in the present investigation. The present work aimed to determine the effect of the technical approach; (1) calcination temperatures of calcium oxide preparation and (2) sintering time of HA synthesis. Thermogravimetric-differential thermal analysis revealed that the cockle shells were calcined at 600 – 1000 °C for 3 hours and had a fine CaO powder. Thus, those sintering temperature is used as the starting point for the calcination of cockle shells. The calcinated CaO powder was then analyzed. The analysis conducted includes yield, functional group analysis using FT-IR, morphological analysis using SEM, and analysis of the composition of Carbon (C), Calcium (Ca), Oxygen (O), and Phosphor (P). Furthermore, hydroxyapatite synthesis (HA) was done with three different sintering times (2, 4, and 6 hours) at 800 °C. The characterized HA was functional group morphology, major elemental in the apatite constituents, and the crystallinity degree. Obtained the optimum temperature result for calcinated at a temperature of 800 °C. The results of HA synthesis obtained by HA quality have approached commercial HA products judging from the composition of Ca, O, and P, but the quality still includes type B of commercial HA. The HA particles obtained are micro-sized, which is 304 nm at a temperature sintering of 800 °C for 4 hours. The micro-sized allows a by-product of cockle shells as raw material HA to be applied as a futuristic biomaterial in bone/teeth implants.

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.

This research aims to determine differences in calcium levels in small crabs (Portunus pelagicus) in three parts, namely carapace/shell, claw feet and abdomen. This research was conducted from May to June 2023 at UD. Bumi Nusantara Pattiro Sompe, Sibulue, Bone Regency, South Sulawesi. The research method used is an experimental method. with three types of samples (abdomen, claw feet and carapace/shell), calcium level parameters with two repetitions. Data were analyzed using T-test. Based on the research results, it shows that the highest calcium levels are in the carapace/shell (46.77%), followed by the claws (41.91%), while the lowest are in the abdomen (40.76%). The conclusion of this study is that there is a significant difference in levels calcium between the carapace/shell and the abdomen and claw legs but did not differ significantly between the abdomen and claw legs.
