Snakehead fish bone is one of the fishery wastes that is potentially used as the raw material for calcium supplement products. In order to make the calcium products easily absorbed and utilized rapidly by human body, supplement products need to be made in nano form. The aims of this study were to determine the effect of the sonication time in the production of Snakehead fish bone nano calcium on the physical profile of the resulted nano calcium, and to obtain the best sonication time. The development of nanocalcium utilized sonication method with 405 Powersonic Ultrasonic Cleaner. The result showed that the best particle size distribution was found on 45 minutes sonication treatment which was 842.3 nm with the highest particle size ranging from 461,6 to 487,5 nm. The average value of the polydispersity index is 1.527. The yield of nano calcium produced from whole fish is 1.331%. The resulting nano calcium has an average white degree of 86.622% and average density of 0.73 g / ml.that nanocalcium had the best particle size distribution at 45 minutes sonication of 842.3 nm with the highest number of particles was around 461,6-487,5 nm with index polydispersity average of 1,527. The yield of nanocalcium from whole fish was 1.331%. The resulted nanocalcium has an average white level of 86.622% and an average density of 0.73 g / ml.
