Judul: Hubungan Komunikasi antara Orang Tua dan Anak terhadap Motivasi Belajar Anak (Kasus: Siswa Kelas 12 MAS Darul Ihsan, Desa Karacak, Kecamatan Leuwiliang, Kabupaten Bogor)
Abstrak: Kualitas komunikasi dan pola komunikasi yang efektif antara orang tua dan anak sangat penting dilakukan dalam meningkatkan motivasi belajar anak karena anak dan orang tua akan saling terbuka, mendukung, berempati, bersikap positif dan memiliki kesetaraan dalam mengkomunikasikan hal-hal apa saja yang dirasakan, diharapkan, dan dipikirkannya. Selain itu, motivasi belajar anak dapat dipengaruhi oleh karakteristik individu yang dimiliki anak maupun orang tua. Tujuan penelitian ini adalah menganalisis hubungan komunikasi yang efektif antara orang tua dan anak terhadap motivasi belajar anak. Metode yang digunakan pada penelitian ini adalah kuantitatif dengan menggunakan kuesioner dan didukung oleh data kualitatif melalui observasi lapang, wawancara mendalam kepada informan, dokumentasi dan studi literatur terkait. Teknik pemilihan responden yaitu menggunakan teknik sensus sebanyak 34 orang siswa. Hasil penelitian menunjukkan terdapat hubungan nyata antara komunikasi orang tua dan anak dan pola komunikasi demokratis dengan motivasi belajar anak. Sementara itu, tidak terdapat hubungan antara karakteristik anak dan karakteristik orang tua dengan motivasi belajar anak., The quality of communication and effective communication patterns between parents and children is very important in increasing children's learning motivation because children and parents will be open, supportive, empathetic, positive and have a good attitude in communicating what things they feel, expect, and think about. In addition, a child's learning motivation can be influenced by individual characteristics that both the child and the parents have. The purpose of this study is to analyze the relationship of effective communication between parents and children to children's learning motivation. The method used in this study is quantitative using questionnaires and is supported by qualitative data through field observation, in-depth interviews with informants, documentation and related literature studies. The respondent selection technique is to use the census technique of 34 students. The results showed that there is a real relationship between parent and child communication and democratic communication patterns with children's learning motivation. Meanwhile, there is no relationship between the characteristics of the child and the characteristics of the parents with the child's learning motivation.

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.
