Hubungan antara Kadar Zn, Se, dan Co pada Rambut Siswa Sekolah Dasar dengan Pendapatan Orang Tua
Abstract
Zinc, selenium, and cobalt are an essential microelements required for the children. The quality of food consumed by the students related to their parents income. The purpose of this research was to observe the relationship between the concentration of Zn, Se, and Co in hair elementary school and their parents income. The analysis of Zn, Se, and Co has been determined by atomic absorption spectroscopy method ( Keywords : microelement, hair, AAS). The research data was processed by one way ANOVA analysis. The ranges in concentrations of Zn, Se, and Co was 111.4 to 747.8 ppm, 0.092 to 1.22 ppm, and 7.64 to 15.29 ppm, respectively. Of the elements studied Zn was found to have the highest concentration and Se the lowest. The average concentration of Zn in girl’s hair about four times (626.8 ppm) higher than boy’s hair (146.8 ppm). The highest concentration of Se was found in boy’s hair from low-income parents but in girl’s hair from high-income parents.
