Judul: Hubungan Motivasi Dan Pola Menonton Dengan Tingkat Kepuasan Mahasiswa Terhadap Program Berita Tv One (Kasus Mahasiswa Departemen Sains Komunikasi Dan Pengembangan Masyarakat, Fakultas Ekologi Manusia Institut Pertanian Bogor).
Abstrak: Television is most effective mass media to transfer information to audience than print media. Recently, people use television not only to get entertainment but also information. One of television programme that content more information and knowledge is news programme. TV One becomes one option which can be a source of recent information and science for the audiences. Based on uses and gratification theory, the audiences were looked actively in using mass media to fulfill their need. It means that someone uses mass media because of a certain motive. Mass media aplication offer expectable satisfaction for the audience. The audiences behaviour in applying media continually will increase day after day, in which they get satisfaction. It called by pattern of watching. Therefore, this reseach examines relationship between motivation, patterns of watching and satisfactory rate of college student on TV One news program. This research was done by a quantitative survey using a descriptive correlational design. Respondents were college student in Bogor Agriculture University and it selected by proportional stratified random sampling technique. Data were processed by the frequency distribution table and mean scores, chi square analysis and rank Spearman correlation test with SPSS for windows version 17. The patterns of watching such as duration and shows option had a significant relation (p<0,05) with whole aspects of motivation for each of them. But, frequency had a possitive significant relation (p<0,05) with entertainment satisfaction. Motivation of information, integration and social interaction had a highly possitive significant relation (p<0,01) with satisfaction rate of information, personal identity, integration, social interaction and entertainment. Motivation of personal identity had a highly significant relation (p<0,01) in motivation of information, personal identity, integration and social interaction. Motivation of entertainment had highly significant relation (p<0,01) with satisfaction of personal identity, integration, social interaction and entertainment.

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.
