Abstrak: This study was aimed to examine the relationship between nutrition and food safety knowledge and snack habit among elementary school children in SDN Sukadamai 03 Bogor as represent high social economic status (SES) and SDN Situgede 04 Bogor represent low SES. This research was a cross-sectional study involving 283 students. Data collection using self administered quesstionnaire. The results show that children with low category of nutrition knowledge in high SES (19.9%) is lower than that in low SES (62.2%), while for food safety knowledge, no high SES children was found with low category whereas in low SES were 11.8%. Snack food commonly eaten by children in both SES were extrudat products. Number of kind snacks consumed by low SES children were higher (>7) than that of high SES (5-7). Nutritional status of most children in both SES were normal. Contribution of snack to energy and nutrients intake ranged from 8.6% (vitamin C) to 15% (energy) while the contribution to energy and nutrients adequacy were ranged from 7.2% (vitamnin C) to 16.1% (calcium). Correlation analysis showed significant relationship between nutrition knowledge, food safety knowledge and snack habits with amount of pocket money (p<0.05), nutritional status (p<0.05) and father and mother education (p<0.05).

Abstrak: The objective of this research was to examine the relationship between consumption of snacks, hygiene and sanitation with morbidity and nutritional status of primary school children. The research design was a cross sectional, and subjects were 88 children of 5 th grade students (10-12 years old). The habit of eating snacks was collected through Food Recall 2x24hours. The results showed that most students had a good level of nutrition knowledge category (54.5%), and as many as 78.6% of food vendors had relatively less knowledge about nutrition. A total of 53.4% of students classified as frequent snacks. Most students had a normal nutritional status 67.0% with low morbidity category (44.3%) and moderate (35.2%). Based on Pearson correlation test there was no significant relationship between knowledge of nutrition and food security pocket with frequency (p=0766 ; r=-0032) and the showed that number of snacks (p=0.253 ; r=-0123). Spearman correlation test results there was a significant relationship between knowledge of nutrition and food security and nutritional status (p=0.039 ; r=0.221). There was a significant relationship between energy snacks consumption and nutritional status (p=0.038 ; r=0.614) and morbidity status (p=0.040 ; r=0.714). There was a significant relationship between protein snacks consumption and nutritional status (p=0.041 ; r=0.525) and morbidity status (p=0.036 ; r=0.308).

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.
