Minerals have a very important role for the human body, fulfillment of mineral needs in humans is obtained by consuming food. One source of animal minerals is Indian scad. Indian scad has a mineral composition that the body needs. This study aims to determine the macro and micro minerals composition of Indian scad. Samples are grouped by body weight, then prepared and tested for macro minerals (Ca, K, Mg and Na) and micro minerals (Cu, Fe, Mn, Se and Zn). The results of grouping the Indian scad based on the average weight obtained by 3 (three) groups, namely group A (72.8 g), B (136.1 g) and C (222.2 g). Proportion of Indian scad has a 69% flesh, 18% head and bones, 13% viscera and gills, 1% blood and water. Macro mineral measurements in each group of fish obtained results: Calcium 40.353 mg/g (A), 37.559 mg/g (B) and 71.334 mg/g (C), Potassium 69.350 mg/g (A), 55.834 mg/g (B) and 67.146 mg/g (C), Magnesium 10.701 mg/g (A), 7.985 mg/g (B) and 11.550 mg/g (C) and Sodium 29.525 mg/g (A), 28.942 mg/g (B) and 29.072 mg/g (C). Micro minerals measurement results: Copper 0.119 mg/g (A), 0.046 mg/g (B) and 0.068 mg/g (C); Iron 0.363 mg/g (A), 0.204 mg/g (B) and 0.324 mg/g (C); Manganese 0.013 mg/g (A), 0.011 mg/g (B) and 0.014 mg/g (C); Selenium 0.464 mg/g (A), 1.007 mg/g (B) and 2.847 mg/g (C); Zinc 0.262 mg/g (A), 0.227 mg/g (B) and 0.431 mg/g (C). Indian scad flesh has a macro and micro minerals composition that varies depending on the body weight of the fish.
