Abstrak: This study aimed to (1) Identify the characteristics of the sample, family characteristics, characteristics of friends and school characteristics, (2) Identify the parenting patern of social-emotion, emotional intelligence, attachment to peers and bullying behavior of the child, (3) Analyze the effect of emotional intelligence and bullying behavior towards children. The study was conducted on two high school in the city of Bogor are SMUN X and SMKN Y. The study used cluster random sampling method that applied for second grade. Based on the analysis of gender showed there is a difference between boys and girls the application of parenting patern of social-emotion and emotional intelligent. The attachment to peers and bullying behavior showed no differences between boys and girls. The results of the Pearson correlation test showed of gender is positively and significantly with the dimensions of emotional intelligence to manage emotions, self-motivation, empathy, total score emotional intelligence and parenting patern of social-emotion. School is positively and significantly associated with emphaty, relationship and physic bullying behavior. School is negatively and significantly with verbal bullying behavior and social bullying behavior. Father's education negatively and significantly associated with self-motivation, empathy dimensions, total score emotional intelligent and attachment to peers. Father’s education positively and significantly with verbal bullying behavior.

Maternal education negatively and significantly with verbal bullying behavior. Family’s income positively and significantly with verbal bullying behavior. Family’s income negatively and significantly with the attachment to peers. Attachment to peers is positively and significantly associated with emotional intelligence dimensions of managing emotions, self-motivation, emphaty, total score emotional intelligent and parenting patern of social-emotion. Attachment to peers is negatively and significantly with verbal bullying behavior. Parenting patern of social-emotion related positively and significantly with to know the emotions, managing emotions, self-motivation, total score emotional intelligence and attachment to peers. Parenting patern of social-emotion related negatively and significantly with verbal bullying behavior and total score bullying behavior. Factors that influence the emotional intelligence with gender, amounth of friends, friend age, attachment to peers and parenting patern of social-emotion.

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.
