Abstrak: The purpose of this research were to analyze the correlation between breakfast, food consumption and nutritional status with learning achievement of student in Papandayan elementary school Bogor. This research used cross sectional study for 60 students. The students of this research consisted of 30 students who seldom have breakfast and 30 students who always have breakfast. The data of breakfast and food consumption was collected by FFQ and recall method for twice (weekday and weekend). Nutritional status was measured by body weight and height of subject while learning achievement taken from average grade of school report and instantaneous memory test. The statistical analysis showed that there was no correlation between breakfast,consumption (energy and protein) and nutritional status with learning achievement (p>0.05).

Abstrak: Fruits and vegetables are very important for consumption, especially for school-age children and adolescents. The purpose of this study were to analyze breakfast habits, fruits and vegetables consumption, and students’s nutritional status of junior high school in Bogor. The design of this study was cross-sectional with purposive sampling technique as much as 50 students in SMP Negeri 8 Bogor. Fruits and vegetables that consumed by students was included low as category. The result showed there was male students consumed breakfast more frequent than female students. Students’s nutritional status were categorized as normal. Correlation test showed there were no significant relationship (p>0.05) between individual and family characteristic, except households income with breakfast habits. There were no significant relationship (p>0.05) between individual and family characteristic, availability of fruits and vegetables at home, and parental habits of fruits and vegetables consumption, except households income with students of fruits consumption. Breakfast habits and fruits and vegetables consumption there were no significantly associated (p>0.05) with students’s nutritional status.

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.
