Judul: Hubungan Persepsi Ibu terhadap Bentuk Tubuh Ibu dan Suami serta Anak dengan Status Gizi
Abstrak: The objective of this research was to analyze correlation of mother perception on mother, husband and child‟s body shape with nutritional status. The research was conducted by applying a cross sectional study design of the 140 mother, husband and child from a population of parents and chidren at Aliya and Mexindo kindergarten school in Bogor. Perception of body shape was obtained from FRS (figure rating scale) method filled by the mothers. Good and bad perception of body shape was obtained from perception of actual body shape and nutritional status on mother, husband and child‟s. The data of nutritional status was directly measured by researcher. The chi-square statistical analysis showed that there were correlation betwen good and bad perception of mother with nutritional status on mother, husband and child‟s (p < 0.05).

Judul: Hubungan Pengetahuan Gizi Ibu dengan Persepsi dan Perilaku Ibu terhadap Jajanan dan Status Gizi Balita
Abstrak: Penelitian ini bertujuan untuk mengidentifikasi ada tidaknya hubungan antara pengetahuan dan persepsi gizi ibu balita dengan perilaku pemilihan jajanan bagi balita dan status gizi. Studi cross sectional dilakukan pada 93 balita yang dipilih melalui purposive sampling di Desa Babakan, Dramaga, Bogor. Data dikumpulkan dengan antropometri dan wawancara meliputi karakteristik balita dan keluarga, kebiasaan makan balita, pengetahuan gizi, persepsi dan perilaku ibu terhadap jajanan. Analisis hubungan dilakukan dengan uji korelasi Spearman menggunakan SPSS. Rata-rata subjek memiliki status gizi normal. Asupan energi dan zat gizi harian rata-rata defisiensi kecuali protein. Jajanan menyumbang rata-rata 33,6% dari total asupan energi, 26,1% protein, 38,4% lemak, dan 37,4% karbohidrat. Hampir semua subjek sering mengonsumsi jajanan dengan frekuensi 3-4 kali sehari. Terdapat hubungan signifikan antara pengetahuan gizi ibu dengan persepsi ibu terhadap jajanan (p=0,000, r=0,358). Persepsi ibu terhadap jajanan perilaku ibu terhadap jajanan (p=0,050, r=0,596). Perilaku ibu terhadap jajanan juga memiliki hubungan negatif dengan frekuensi jajan balita (p=0,005, r=-0,289). Status gizi balita berhubungan dengan pengetahuan gizi ibu (p=0,003, r=0,779).

Judul: Pemurnian dan karakterisasi protein inhibitor RNA helikase virus hepatitis C
Abstrak: Hepatitis C virus (HCV) infection is the second most common chronic viral infection in the world with global prevalence. This infection is contribution to chronic hepatitis and liver cirrhosis, often leading to hepatocellular carcinoma. There is no effective drug and vaccine available against HCV. The current standard treatment, a combination of pegylated interferon-α with ribavirin, is limited by its suboptimal response rate in a significant patient population, side effects, and affordability. Therefore, development of effective drug is needed. One approach to find out the candidate of antiviral drug is to discover the inhibitor of enzyme that essential for virus replication, such as RNA helicase. Streptomyces chartreusis 5-095 produce the inhibitor of HCV RNA helicase. The aim of this study was to purify the protein inhibitor which has inhibition activity against ATPase activity of RNA helicase HCV from S. chartreusis 5-095. The supernatant of culture S. chartreusis 5-095 exhibited high inhibiton activity against ATPase activity of RNA helicase HCV (approximately 72%) at 10 days of incubation. The extracellular protein inhibitor was partially purified by procedures of precipitation with ammonium sulfate to 65% saturation and gel filtration (Sephadex G50) using methanol water solution (4:6) as an eluen. The purity of protein inhibitor was monitored by SDS PAGE. The protein inhibitor showed a relative molecular mass were estimated to be 14 kDa and increased the purity 23,08 fold than those of the crude protein. The specific activity and IC50 after purification were 13,1338 U/mg and 0,0767 mg/mL, respectively. The activity of purified protein inhibitor showed its stability over pH range from 5-8 and optimum at pH 7,4. The inhibition activity showed its stability up to 70% at temperature 100 oC. The purified protein inhibitor relatively stable its activity at storage in the range of -20 oC to room temperature for 35 days.
