Abstract

This study aims to evaluate the nutritional and mineral composition of the seaweeds Caulerpa lentilifera and Caulerpa racemosa originating from the waters of Takalar Regency, South Sulawesi, Indonesia. The results showed that the proximate composition between the two Caulerpa species, Caulerpa lentilifera had the highest ash content (63.83%) while C. racemosa had the highest carbohydrate content of 38.18%. The results of the mineral analysis showed that C. lentillifera and C. racemosa contained macro and micro minerals. The highest macromineral content is Sodium (10.040% & 16.280%) and followed by Potassium (3.958% & 2.195%), Magnesium (59.201 ppm & 519.201 ppm), Calcium (0.521% & 0.466%) and Phosphorus (0.270% & 0.335%). The highest micro minerals in the two types of seaweed from the largest are Fe (756,1805 ppm & 386,1202), Manganese (59,201 ppm & 519,062 ppm), zinc (10,079 ppm & 3,366 ppm), and Cuprum (5,496 ppm only in C. racemosa). This study revealed that C. lentilifera and C. racemosa contain constituents with proximate and mineral composition as potential sources of plant foods and good sources of mineral supplements.
