Judul: Analisis Asupan Zat Gizi Mikro dan Hubungannya dengan Status Gizi pada Ibu Hamil di Wilayah Bogor
Abstrak: Konsumsi makanan yang memenuhi kebutuhan gizi merupakan salah satu caranya faktor yang harus diperhatikan sebelum dan selama kehamilan. Kekurangan zat besi adalah kekurangan gizi yang paling umum dan paling luas di dunia. Untuk mencatat serta asupan mikronutrien seperti vitamin yang dapat meningkatkan status zat besi wanita hamil. Penelitian ini berdasarkan data yang dihasilkan dari Studi Gizi Status dan Pola Makan Ibu Pra Hamil (pada usia subur), Ibu Hamil dan Menyusui dilaksanakan oleh SEAFAST Center IPB. Itu Penelitian dilakukan di wilayah Bogor yang meliputi enam kecamatan. Subjek adalah ibu hamil yang pemeriksaan hemoglobin dan ferritinnya berjumlah 45 orang kehamilan trimester II. Variabel yang mempunyai korelasi nyata positif dengan kadar feritin berdasarkan Korelasi Pearson adalah vitamin A (r=0,415; p<0,05), vitamin B12 (r=0,402; p<0,05), dan asupan vitamin C (r=0,356; p<0,05). Asupan vitamin B12 memiliki pengaruh paling kuat terhadap kadar feritin dengan persamaan regresi Ferritin = -3,851+10.931 vitamin B12. Ada hubungan nyata yang negatif antara asam folat asupan dan kadar feritin (r =-0,355; p<0,05).

Judul: Hubungan Tingkat Kecukupan Protein dan Zat Besi (Fe) dengan Kadar Hemoglobin Ibu Hamil di Kota Bogor
Abstrak: Levels of hemoglobin is one of the most common indicator used to determine the status of iron deficiency anemia, which is closely related by intake of protein and iron that increased and must be adequate during pregnancy. The aim of study was to explain relationship between %RDA of protein and iron with levels of hemoglobin at pregnant mother in Bogor City. The design of this study was cross-sectional study, and the number of samples were 45 pregnant women. The result of the research show that the anemia prevalence was 22.2%. Consumption of animal foods as a source of iron was still low (60.3 g) it might for 68.8% of the samples had inadequate iron. Intake of vitamin C as a enhancer of iron bioavailability was 27.0 mg. This study has shown that intake of heme iron (6.9 mg) was lower than the non-heme iron (10.4 mg). Most of sample on group anemia and non anemia has %RDA of energy and protein as a deficit level of heavy and then %RDA of vitamin A, vitamin C, folic acid, and iron as a deficit. Results test correlation show there is no relation between %RDA of protein and iron with levels of hemoglobin (p>0.05)

Judul: Penggunaan Metode Homotopi untuk Menyelesaikan Persamaan KdV (Korteweg-de Vries)
Abstrak: Natural phenomena can be explained using nonlinear mathematical models. In this paper, we studied the solution of KdV equation using the Homotopy method. The KdV equation is used for describing both surface and internal waves. One of the solutions is called a solitary wave. The use of homotopy method to solve the KdV equation required a nonlinear operator which was determined by the nonlinear form of the KdV equation itself. Based on this operator, a recursive formula was obtained to get a sequence of the KdV solution. The higher the sequence order of the sequence used, the closer to the exact solution of the KdV equation.
