Analysis of calcium levels in beef bones from kaledo waste

Kaledo is one of the special culinary from Central Sulawesi which containing beef bones. The large number of restaurants that provide kaledo in their menus resulted in the amount of beef bone waste that cannot be consumed. This waste can cause environmental problems. However, the bones have the number of minerals, one of them is calcium (Ca). Ca is a mineral that is needed by the body in maintaining body functions. This study aimed to determine the calcium levels in beef bones from kaledo waste which was taken randomly from the kaledo restaurant in Palu. Determination of calcium levels in beef bones from kaledo waste used atomic absorption spectrophotometer. The results of the analysis showed that the water content was 4.5950%, and the ash content was 61.7424%. The analysis of calcium levels measured at a wavelength of 422.7 nm was 19,6800 mg/L. The results of this study are expected to be a source of information about the levels of calcium contained in cow bones from kaledo waste, and it can be used further as a substance in the utilization of beef bones from kaledo waste as a food that can meet the body's need for calcium intake in preventing stunting.
