Judul: Persepsi Masyarakat terhadap Media Luar Ruang di Jalan Margonda Raya Kota Depok sebagai Media Periklanan
Abstrak: The research about people’s perception was conducted in order to identify the existence of outdoor media in Margonda Raya Street, Depok City, West Java. Quantitative method was used as the primary method in this research. This research was conducted using survey research design with descriptive-correlational approach. Descriptive in this research means describing respondent characteristics, people’s perception toward visual communication aspects, typology characteristics, and outdoor media aesthetics. Moreover, Correlational in this research means trying to explore factors that related to people’s perception and try to examine correlation between variables. By identifying people’s perception, it will enable us to describe people’s response toward outdoor media. As many as 94 respondents from Margonda Raya Street, Depok City was selected as sample in this research. The research results showed that the public perception of visual communication aspects on outdoor media is good, while the public perception of the outdoor media typology and aesthetic outdoor media is good enough. Further study related to outdoor media is expected to learn about outdoor media in Depok City based on City Planning (RTRK).

Judul: The Effectiveness of Outdoor Media on Community Behavior in Dispose of Waste (Case: Ciliwung's River Bank, Sempur Village, Central Bogor Subdistrict, Bogor City, West Java)
Abstrak: Media luar ruang merupakan media penyampai pesan atau informasi yang memiliki berbagai karakteristik pesan dan diletakkan di ruang terbuka yang cukup strategis agar dapat menjangkau khalayak luas. Media luar ruang sering digunakan sebagai alat yang dapat mengubah perilaku seseorang. Sebagaimana maraknya pemasangan media luar ruang di tepi sungai yang berisi larangan membuang sampah sembarangan. Hal tersebut ditujukan agar masyarakat memiliki perilaku yang baik dalam membuang sampah. Penelitian ini bertujuan untuk menganalisis karakteristik individu dan karakteristik pesan yang memiliki hubungan terhadap intensi dan perilaku masyarakat dalam membuang sampah. Penelitian ini menggunakan pendekatan kuantitatif yang dilakukan menggunakan kuesioner dan didukung dengan data kualitatif melalui wawancara mendalam serta observasi. Hasil penelitian menunjukkan bahwa tidak ada hubungan antara karakteristik individu maupun karakteristik pesan dengan intensi. Namun, intensi memiliki hubungan dengan perilaku masyarakat dalam membuang sampah., Outdoor media is a medium for delivering messages or information that has various message characteristics and is placed in an open space that is strategic enough to reach a wide audience. Outdoor media is often used as a tool to be able to change a person's behavior. Like the rampant installation of outdoor media on the banks of the river which prohibits littering. This is intended so that people have good behavior in disposing of waste. This study aims to analyze individual characteristics and message characteristics that have a relationship with people's intentions and behavior in disposing of waste. This research uses a quantitative approach which is carried out using a questionnaire and is supported by qualitative data through in-depth interviews and observations. The results showed that there was no relationship between individual characteristics and message characteristics with intention. However, intention has a relationship with people's behavior in disposing of waste.

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.
