Abstrak: Based on the findings of the Food and Drug Supervisory Agency (BPOM) in 2011, was found 420 items (132 259 packs) foods are not requirement (Sindo 2012). The purpose of this study was to analyze the effect of consumer vulnerability on food packaging purchasing behavior in Bogors’ urban and rural area. This study used cross sectional study. The samples of this study was 80 households’ who consumed food packaging product that come from complete family and choosen by using simple random sampling. The result showed significant differences of households’ purchasing behavior on food packaging product and consumer vulnerability. Moreover, there was negative significant correlation between geographical location, mothers’ education, and expenditure of food packaging product with consumer vulnerability. Factor that affect the vulnerability of consumer is geographical location. Age, expenditure of food packaging product, family expenditure, and consumer vulnerability was influenced purchasing behavior

Abstrak: Many producers have produced packaging food products because technological advances of food and packaging. The purpose of this study was to analize the effect of values and type of households on food packaging products purchase behavior in Bogors’ rural and urban area. The design of study was cross sectional. The sample of this study was 80 households who consume food packaging product with complete family and choosen by simple random sampling in Bogors’ rural and urban area. The result of this study showed that households’ values, type and purchasing behavior on food packaging product in urban area were better than in rural area. Moreover, there was a relationship between values and type of consumer with purchasing behavior of food packaging products. Factor which effect type of consumer were housewife education and family expenditure. Factors which effect consumer behavior were age, housewife education, size of families, and families income.

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.
