Abstrak: Naget yang ada di pasaran biasanya berupa naget ayam, sapi, dan ikan. Di pasaran, naget sapi belum banyak dikenal masyarakat. Penelitian ini bertujuan menganalisa persepsi, perilaku konsumen, dan hubungan persepsi dan perilaku konsumen masyarakat dewasa di Kota Bogor terhadap produk naget daging sapi. Sampel diambil sebanyak 100 responden dewasa di Kota Bogor dengan teknik disproportionate stratified random sampling. Tahap dalam penelitian adalah menggunakan rumus Slovin untuk menentukan jumlah sampel dari populasi, menentukan jenis dan pengumpulan data, kemudian pengolahan data menggunakan uji Chi-Square dan Rank Spearman. Hasil penelitian didapatkan bahwa terdapat hubungan antara persepsi dan perilaku konsumen yang signifikan antara persepsi kemasan dan cara penyajian. Ukuran kemasan yang paling banyak dipilih adalah 250 g dengan frekuensi membeli yaitu satu bulan sekali. Terdapat hubungan korelasi antara karakteristik (pendapatan, pekerjaan, dan pendidikan) dengan perilaku konsumsi (frekuensi, harga, dan ukuran yang dipilih untuk membeli naget sapi).

One of them that is mostly important is a beef. A restaurant as business community has higher beef consumption and continuity than household consumption, so that is potential to be a purpose of beef marketing. Bogor city is a region that has economically strategic location near to Jakarta as the capital city, especially in service aspect. Bogor has highly level of food consumption and become the 3rd biggest of its consumption level in West Java with the beef consumption as high as.

The sample used are 60 samples. Data of this research are primary data (questioner and interview) and secondary data (literatures, magazines, internet, latest research journal, and else). The tools of its analysis are descriptive analysis to describe respondents behavioral and characteristic in buying beef; Spearman Rank test to examine questioners validity; Cronbach Alfa test to examine reliability of the questioner; and Multidimensional Scaling (MDS) to determine respondents perception. This research result that restaurants in Bogor city have some common characteristics, they are Padang Restaurant that have been going on 7 years, had mean of income per month over Rp 10.000.000,- and processed them in rendang. In taking decision process, most of restaurants bought beef in reason by internal stimulus; there are the part of beef, the freshness, and the price.

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.
