Analisis Kadar Mineral dalam Abu Buah Nipa (Nypa fructicans) Kaliwanggu Teluk Kendari Sulawesi Tenggara

Abstract

Research about Levels of ash analysis in Nipa Fruit (Nypa fructicans) Kaliwanggu Kendari Gulf South East Sulawesi have been done.  Research carried out by gravimetric method and AAS. The ash content of old nipa fruit at a temperature 450°C dan 550°C obtained amounted to 1.01% and 0.89%. while the young nipa fruits obtained ash content of 0.88% and 0.86% at450°C dan 550°C. Mineral content of old nipa fruit which had become ash at a temperature of 450°C obtained at 1.3769 ppm, 7.9167 ppm, 3.7876 ppm, 9.2365 ppm, respectively for Fe, Mg, K, and Na. On the other hand, at a temperature of 550°C obtained at 1.1153 ppm, 8.0127 ppm, 3.7990 ppm and 9.3634 ppm, respectively for Fe, Mg, K, and Na. On young fruit nipah obtained concentration of 0.8769 ppm, 7.9939 ppm, 3.8260 ppm, 9.4041 ppm, respectively for Fe, Mg, K, and Na at ash temperature 450°C. Meanwhile, at a  ash temperature of 550°C obtained concentration of 0.9230 ppm, 7.9738 ppm, 3.7468 ppm and 9.3861 ppm, respectively for Fe, Mg, K, and Na. The water content obtained from the old and young nipa flesh fruit obtained at 41.86% and 33.49%, respectively.
