Judul: Analisis Bentuk In-Store Promotion Yang Paling Mempengaruhi Keputusan Impulse Buying Konsumen (Studi Kasus : Konsumen Ramayana Bogor Trade Mall)
Abstrak: Impulse buying behavior usually happens in consumers who come into modern store. This phenomenon motivates retailers to carry out in-store promotion. Because in-store promotion is one of the alternative media to attract consumers to buy a product. Based on this problem will be investigated about: (1) How about the impulsive behavior Ramayana Bogor Trade Mall consumers? (2) How is the impact of in store promotion to influence impulse buying decision by consumers? (3) What is the type of in store promotion that influences decision of impulse buying most? Data which are used consist of primary data and secondary data. Primary data is obtained by survey, while secondary data is obtain by reference study. Data were analyzed by using descriptive methods, multiple linear regression, and Structural equational modeling (SEM) which is supported by Microsoft Office Excel 2007, LISREL 8.30 and SPSS 17.0. Results from descriptive analysis, 75% of respondents used to plan what they want to buy. While consumers always planned purchase but there's always extra stuff they bought without a plan. It can be inferred from 99% of consumers bought additional items while shopping. Based on analysis of Structural Equational Modeling (SEM), influence coefficient (t) of sales promotion, store display and personal selling against impulse buying is a row of 1.14, 0.31, and -0.55 (< table of t = 1.96). It means none variable in store promotion which have an influence on impulse buying behavior of consumers. Based on regression analysis, F values for 2.157 and p-value 0.098 at alpha level 0.10 shows that in-store promotion affects impulse buying decisions Ramayana Bogor Trade Mall consumers. Β values for sales promotions, store displays, and personal selling are respectively 0.085, 0.359, and -0.062. So the type of in-store promotion that influences most consumer buying decisions Ramayana Bogor Trade Mall is a store display. The conclusions of this study were taken based on the results of multiple regression analysis. Structural Equation Modeling (SEM) has high sentitifity rate in it’s counting element variable, so it does not result significant difference.

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.
