Judul: Persepsi Santri dalam  Mengkonsumsi Susu Kambing (Studi Kasus di Pondok Pesantren Modern  Sahid Desa Gunung Menyan Kecamatan Pamijahan Kabupaten Bogor)
Abstrak: The objectives of this study were: 1) to identify characteristic and perception of students of PPMSGM about milk goat products and their consumption decisions; 2) to analyze the correlation between characteristic of consumers and their perception toward milk goat product and 3) to analyze correlation between perception toward milk goat and their consumption decision. The sample of this study was 86 people and taken by using accidental sampling. Primary data was obtained by questionnaire and interview to student and official members of PPMSGM. Secondary data was obtained from relevant institutions which related to this research topic. Data were analyzed by descriptive and correlation analyses by using Rank Spearman, Chi Square and statistical test. The results were: 1) no correlation among age, sexes, and respondents’ perception of milk goat; 2) a negative correlation between income and respondents’ perception; 3) a positive correlation between source of information and flavor and benefit; 4) a positive correlation between product knowledge and package; 5) a positive correlation between taste and consumption decision. Almost positive the student perception toward milk goat and they also decided to consume it.

Judul: The Perceptions and Consumer Behavior of IPB Students in  Consuming UHT Milk and Pasteurized Milk
Abstrak: Mahasiswa sebagai penerus bangsa harus memenuhi kecukupan gizi, salah satunya dengan mengonsumsi susu. Penelitian ini bertujuan mengetahui persepsi dan perilaku konsumen mahasiswa IPB terhadap konsumsi susu UHT dan susu pasteurisasi. Responden contoh dalam penelitian ini sebanyak 203 mahasiswa IPB dari berbagai fakultas yang dipilih dengan menggunakan tenik penarikan contoh acak berlapis. Data bersifat nominal di uji dengan uji Chi square dan data bersifat ordinal di uji Rank Spearman. Hasil penelitian didapatkan bahwa persepsi terhadap harga dan kemasan pada susu UHT dan susu pasteurisasi tidak berbeda nyata. Frekuensi minum susu mahasiswa yaitu 2-3 kali seminggu dengan jenis susu UHT yang dominan dikonsumsi. Kemasan yang paling banyak dibeli serta volume sekali konsumsi minum susu yaitu 250 mL Terdapat hubungan korelasi antara karakteristik responden (uang saku dan program studi) dengan perilaku mengonsumsi susu (frekuensi minum, kemasan susu dan jenis susu yang dikonsumsi). Hubungan korelasi persepsi susu UHT dan susu pasteurisasi terhadap perilaku mengonsumsi (jenis susu yang dikonsumsi dan frekuensi minum) didapati hasil yang signifikan., Students as the nation's successor must fulfill adequate nutrition, one way is by consuming milk. This study aims to determine the perceptions and consumer behavior of IPB students on the consumption of UHT milk and pasteurized milk. The sample respondents in this study were 203 IPB students from various faculties who were selected using The Stratified Random Sampling technique. Nominal data were tested by the Chi square test and ordinal data were tested by the Rank Spearman test. The results showed that perception of the price and packaging of UHT milk and pasteurized milk was not significantly different. The frequency of drinking student milk is 2-3 times a week with dominant UHT milk consumed. The most purchased packaging and the volume for one consumption of drinking milk is 250 mL. There is a correlation between the characteristics of respondent (allowance and study program) and behavior of consuming milk (frequency of drinking, milk packaging, type of milk consumed). The correlation between perceptions of UHT milk and pasteurized milk on consumption behavior (type of milk consumed and frequency of drinking) was found to be significant. All correlation directions obtained were positive with strength of correlation relationship ranging from very weak to moderate.

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.
