Judul: Faktor-Faktor yang Mempengaruhi Perilaku Kunjungan Ibu Balita ke Posyandu di Wilayah Kerja Puskesmas Kebayoran Lama
Abstrak: Tujuan penelitian ini adalah menganalisis faktor-faktor yang mempengaruhi perilaku kunjungan ibu ke posyandu. Desain penelitian yang digunakan adalah cross sectional study dengan jumlah contoh sebanyak 75 ibu yang memiliki balita 6-59 bulan yang dipilih secara acak di wilayah kerja Puskesmas Kecamatan Kebayoran Lama. Perilaku kunjungan ibu balita dibagi menjadi tiga komponen yang terdiri dari pengetahuan, sikap dan tindakan kunjungan ibu ke posyandu. Hasil uji korelasi Spearman menunjukkan hubungan yang signifikan (p < 0.05) antara pengetahuan ibu tentang posyandu dengan dukungan keluarga; sikap ibu tentang posyandu dengan pendidikan, motivasi dan dukungan tokoh masyarakat; serta pengetahuan dengan sikap ibu. Hasil uji regresi logistik menunjukkan bahwa motivasi mempengaruhi sikap ibu untuk berkunjung ke posyandu dengan faktor risiko 8.286 kali, yang artinya ibu yang memiliki motivasi negatif berisiko 8.286 kali lebih besar untuk memiliki sikap kunjungan ke posyandu yang kurang baik.

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.
