Abstract

ABSTRAKLogam besi merupakan jenis mineral yang sering ditambahkan ke dalam produk susu kehamilan untuk memenuhi angka kecukupan gizi dan nutrisi bagi ibu dan janin. Analisis kadar logam besi (Fe) pada susu bubuk formula ?A? dan ?B? menggunakan Spektrofotometri Serapan Atom (AAS) dengan teknik kurva kalibrasi. Preparasi sampel menggunakan metode destruksi kering melalui pengabuan sampel pada suhu 4200C dan destruksi basah menggunakan asam kuat HNO3 dan HCl pekat untuk melarutkan sampel. Hasil penelitian menunjukkan bahwa kadar besi pada susu ?A? dan ?B? dengan metode destruksi kering dan basah secara berturut-turut 247,97 ? 0,98 mg/kg dan 397,40 ? 13,31 mg/kg untuk sampel A, 284,96 ? 4,08 mg/kg dan 517,72 ? 12,00 mg/kg untuk sampel B. Hasil validasi metode menunjukkan bahwa metode destruksi kering relatif lebih baik digunakan untuk analisis logam Fe dibandingkan dengan metode basah dengan prosentase recovery (akurasi) dan simpangan baku (presisi) 100,95 ? 0,031% dan 1,00% untuk sampel susu A, 96,79 ? 0,021% dan 0,54% untuk sampel susu B. Sedangkan dengan metode destruksi basah diperoleh prosentase recovery (akurasi) dan simpangan baku (presisi) sebesar 98,41 ? 0,67% dan 2,43% untuk sampel susu A, 93,81 ? 0,110% dan 3,20% untuk sampel B.Kata kunci: Logam besi, Destruksi Basah, Destruksi kering, Susu bubuk kehamilanABSTRACTThe iron metal is a type of mineral that is often added to pregnancy dairy products to meet the number of nutritional adequacy and nutrition for the mother and fetus. Analysis of iron (Fe) contain in milk powder of formula "A" and "B" using by atomic absorption spectrophotometry method (AAS) with calibration curve technique. Sample preparation using dry destruction was carried out by ashing the sample at 420 oC and wet destruction using the concentrated nitric and chloride acid to dissolve the sample. The results showed that iron content in milk "A" and "B" with dry destruction methods was 246.48 ? 0.99 mg / kg and 283.93 ? 4.08 mg / kg and with wet destruction of 216.66 ? 6.44 mg / kg and 257.36 ? 2.28 mg / kg. The result of method validation showed that dry destruction method was better than wet method with recovery percentage (accuracy) and standard deviation (precision) 100,95 ? 3,10% and 0,41% for milk "A", 96,76 ? 1 , 76% and 1.43% for milk "B". While the wet destruction method obtained the percentage of recovery (accuracy) and standard deviation (precision) of 97.80% ? 2.00 and 3.39% for milk "A", and 93.31% ? 0.93 and 2.34 for milk "B".Key words: Iron metal, Wet Destruction, Dry destruction, Milk powder pregnancy
