Judul: Faktor-faktor yang Berhubungan dengan Konsumsi Buah dan Sayur Anak Usia Sekolah di Bogor.
Abstrak: Latar belakang penelitian ini adalah masih rendahnya konsumsi buah dan sayur, termasuk anak usia sekolah. Tujuan penelitian ini adalah menganalisis faktor-faktor yang berhubungan dengan konsumsi buah dan sayur pada anak usia sekolah dasar di Bogor. Desain penelitian ini adalah cross sectional dengan teknik penarikan contoh secara purposive sebanyak 108 contoh di dua sekolah dasar di Bogor yaitu SDN Cibanteng 01 Kabupaten Bogor dan SDN Papandayan Kota Bogor. Konsumsi buah dan sayur di SDN Papandayan lebih besar dibandingkan dengan SDN Cibanteng. Terdapat perbedaan yang nyata (p<0.05) konsumsi buah anak berdasarkan suku dan pekerjaan ibu. Terdapat perbedaan yang nyata (p<0.05) konsumsi sayur anak berdasarkan suku. Pengetahuan gizi anak dan pendidikan ayah dan ibu berhubungan signifikan positif (p<0.05) dengan konsumsi buah dan sayur anak, demikian pula uang saku, ketersediaan buah, dan pendapatan keluarga berhubungan signifikan positif (p<0.05) dengan konsumsi buah anak.

Judul: Konsumsi Buah dan Sayur pada Anak Sekolah Dasar menurut Status Sosial Ekonomi Berbeda di Kota Bogor
Abstrak: This research aim to examine the consumption of fruit and vegetable on elementary school children according to different socio-economic status in Bogor City. This research used the design of cross sectional study. Subjects taken in random who represents students who are registered in 20 elementary schools in Bogor City. There were no difference between the frequency of fruit and vegetable consumption of students in both groups of social economy. The contribution of vitamins A and C from fruit and vegetable consumption and the adequacy of the students were still low. There were no correlation between socio-economic families with the frequency of fruit and vegetable consumption, but there were a correlation between family size with vegetable consumption frequency, mother's education with the contribution of vitamin C in vegetable, and allowance with the contribution of vitamin C from vegetable consumption of students. There were no correlation between fruit and vegetable consumption frequency with the nutritional status of students.

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.
