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.

Samples were taken from as many as 100 adult respondents in the city of Bogor with a disproportionate stratified random sampling technique. The stage in the research was to use the Slovin formula to determine the number of samples from the population, determine the type and collection of data, then process the data using the Chi-Square and Rank Spearman tests. The results showed that there was a significant relationship between consumer perception and behavior perceived quality and consumption frequency. The most widely chosen packaging size is 250 gs with a frequency of buying once a month. There was a correlation between characteristics (income, occupation, and education) with consumption behavior (frequency, price, and price chosen to buy beef nuggets).

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.
