Abstract

The aims of the research were to find out mineral composition of seaweed Gracilaria.sp macro mineral elements i.e of Ca, Mg, Na, and K, and micro mineral elements Cu, Zn, Fe, Co, I, Mn and Se. Gracilaria.sp was destroyed by dry digestion and wet digestion and mineral content was measured using atomic absorption spectroscopy (AAS). The results showed that dry digestion produced more minerals than wet digestion. Gracilaria.sp contains various minerals, each of which is sodium (3816 ppm), potassium (869.75 ppm), calcium (905 ppm), magnesium (0.231 ppm). For micro minerals the content of Cu(1.06 ppm), Zn(2.16 ppm), Fe(0.678), Co(0.15) and Mn(6.70 ppm). Apart from Gracilaria.sp various other plants such as turi leaves, cassava leaves, Imperata cylindrica and grass also contains macro minerals and micro minerals.
