Judul: Pengetahuan, Perilaku Membaca Label Gizi dan Keputusan Pembelian, serta Persepsi terhadap FOP Nutrition Labelling Pangan Olahan pada Remaja SMA dan SMK.
Abstrak: Penelitian ini bertujuan untuk menganalisis perbedaan pengetahuan informasi nilai gizi, perilaku membaca label gizi dan keputusan pembelian, serta persepsi FOP nutrition labelling pangan olahan antara contoh SMA dengan contoh SMK. Penelitian cross-sectional ini melibatkan contoh sebanyak 34 siswa SMA Kornita dan 47 siswa SMKN 3 Bogor yang berada di kelas 12. Data karakteristik contoh dan sosial ekonomi keluarga, pengetahuan, perilaku membaca label gizi dan keputusan pembelian, serta persepsi terhadap FOP nutrition labelling pangan olahan dikumpulkan dengan cara pengisian kuesioner oleh contoh. Hasil penelitian menunjukkan bahwa rata-rata dan standar deviasi pengetahuan tentang label informasi nilai gizi dan fungsinya pada contoh SMA (46.6 ± 13.4) adalah signifikan (p<0.05) lebih rendah daripada SMK (60.5 ± 15.1). Sebanyak 85.3% contoh SMA dan 53.2% contoh SMK memiliki pengetahuan informasi nilai gizi kategori kurang. Terdapat perbedaan yang signifikan (p<0.05) pada aspek yang menjadi pertimbangkan contoh SMA maupun SMK saat membeli produk yaitu label halal, kandungan gizi dan rasa. Perilaku membaca label gizi contoh SMA (61.8%) maupun contoh SMK (72.3%) tergolong jarang dan memilih kandungan lemak sebagai aspek informasi nilai gizi yang sangat penting diperhatikan oleh contoh. Tidak terdapat perbedaan yang signifikan (p>0.05) mengenai keputusan pembelian produk pangan antara contoh SMA maupun SMK. Terdapat perbedaan yang signifikan (p<0.05) terhadap pemilihan desain FOP traffic light and claim antara contoh SMA dan SMK. Terdapat perbedaan yang signifikan (p<0.05) terhadap persepsi contoh mengenai pencantuman traffic light.

Judul: Pengetahuan, persepsi, sikap, dan perilaku membaca label informasi gizi pada mahasiswa
Abstrak: Label informasi gizi merupakan label yang memuat informasi mengenai kandungan gizi di dalam produk pangan yang menjadi media sangat penting untuk mentransfer informasi mengenai karakteristik dari suatu produk pangan. Tujuan penelitian ini adalah untuk menganalisis pengaruh karakteristik individu, karakteristik keluarga, pengetahuan, persepsi, dan sikap terhadap perilaku membaca label informasi gizi produk pangan pada mahasiswa Strata Satu (S1) Institut Pertanian Bogor. Disain penelitian ini menggunakan cross sectional study dengan metode survei yang dilakukan di Kampus Institut Pertanian Bogor (IPB), Kecamatan Dramaga, Kabupaten Bogor. Penelitian ini melibatkan 400 mahasiswa IPB yang dipilih dengan menggunakan teknik multistage random sampling dengan lapis jenis kelamin. Terdapat perbedaan nyata antara responden laki-laki dan perempuan dalam hal pengetahuan, sedangkan persepsi, sikap, dan perilaku membaca label informasi gizi tidak berbeda nyata. Sikap berpengaruh nyata terhadap perilaku membaca label informasi gizi., Nutrition labels is a label that contains information about nutrition in a food product which become very important media to transferring information about characteristic in a food product. The aim of this research was to analyze the effect of individuals characteristics, family’s characteristics, knowledge, perception, and attitude on reading behavior of nutrition labels of undergraduate students of Bogor Agricultural University. The design of this research used cross sectional study with survey method which conducted in Bogor Agricultural University, Dramaga district, Bogor regency. This research involved 400 Bogor Agricultural University’s students selected by multistage random sampling based on gender. There was significant difference between male and female for knowledge, meanwhile the difference was not appear significant for perception, attitude, and reading behavior of nutrition labels. Attitude influenced on reading behavior of nutrition labels.

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.
