Judul: Analisis Faktor-Faktor yang Mempengaruhi Perilaku Konsumen dalamKeputusan Pembelian Susu Cair Ultra Milk (Studi Kasus Mahasiswa S1 Institut Pertanian Bogor)
Abstrak: Indonesian people’s growing awareness of the impotance of liquid milk as a product for maintaining health, brings about an opportunity of marketing a product of liquid milk. A liquid milk industry is in fact dominated by popular players, among other things, Ultra Milk. Therefore, to maintain its market, Ultra Milk is supposed to know the factors influencing the making of the desicion of buying liquid milk. The consumers who have become a research target is a student of bachelor degree of Bogor Institute of Agriculture who has bought some liquid milk of Ultra Milk. This research is intended to as follows : (1) to identify the characteristic of the costumers of Ultra Milk, (2) to identify a process of deciding to buy Ultra Milk, (3) to analyze the factors influencing the customers’ decision to buy Ultra Milk, (4) to analyze customers attitude towards the attributes owned by Ultra Milk. The data used in this research are primary and secondary. The primary data are taken from the spreading of questionaires and the secondary data are taken from a library study, information on the internet, and a study of references. Secondary data are taken frombook’s study, internet and literature’s study.The technique to take samples used in this research is a quota sampling. The means of analyzing are the descriptive analysis, the factor analysis and a model of MultiattributeFishbein analysis with the help of SPSS software version 17 and Microsoft Excel. The results of the research show that the majority of the customers of Ultra Milk’s liquid milk are the female university students (62%), aged 21 years old (46%), their origins of Jakarta, Bogor, Tangerang and Bekasi (41%). Their average monthly expenses are from 500,001 rupiahs to 1,000,000 rupiahs ( 67%). The process to decide on buying the customers of Ultra Milk’s liquid milk goes through 5 phases namely, recognizing the need, searching for the information, evaluating the alternatives, buying and evaluating the. Referring to the factor analysis, there are 3 factors which are seen, among other things, the factors of individual characteristic, the knowledge of a product and a personality, and the source of information. Referring to the analysis of multiattributeFishbein, the customers put emphasis on the halal of a product, the quality of product and the security of a consuming process while buying liquid milk. The customers see Ultra Milk’s liquid milk from the quality of a product, the halal of a product and the security of a consuming process. Referring to the Fishbein score of 258.68, it is concluded that the product of Ultra Milk’s liquid milk is considered as a good category.

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.
