Judul: Faktor-Faktor yang Mempengaruhi Minat Siswa SMA/SMK untuk Melanjutkan Pendidikan
Abstrak: Minat adalah kencenderungan seseorang untuk menampilkan suatu perilaku. Berdasarkan theory of planned behavior (TPB), minat dipengaruhi oleh sikap, norma subjektif, serta kontrol perilaku. Penelitian ini bertujuan untuk menganalisis faktor yang mempengaruhi minat siswa untuk melanjutkan pendidikan. Rsponden dalam penelitian ini adalah 80 siswa (17-20 tahun) yang bersekolah di SMA/SMK di Kabupaten Bogor Barat yang dipilih secara random sampling. Hasil penelitian menunjukkan bahwa tingkat pengetahuan dan sikap siswa berada pada kategori tinggi sedangkan tingkat norma subjektif, kontrol perilaku, dan minat siswa berada pada kategori sedang. Uji hubungan menunjukkan bahwa pengetahuan memiliki hubungan positif signifikan dengan kontrol perilaku. Sikap, norma subjektif, dan kontrol perilaku memiliki hubungan positif signifikan dengan minat. Uji pengaruh menunjukkan bahwa usia ayah, tingkat pendidikan ibu, besar keluarga, sikap, serta norma subjektif memiliki pengaruh terhadap minat siswa untuk melanjutkan pendidikan (p<0.01).

Judul: Faktor-faktor yang mempengaruhi minat siswa melanjutkan pendidikan ke perguruan tinggi dengan menggunakan Regresi Logistik (Studi Kasus: minat siswa SMU/sederajat di Kab.Garut terhadap STAI Al- Musaddadiyah)
Abstrak: Interest is a desire that tends to settle in a person to drive on a particular option as a necessity, then continue to be realized in real action with the attention on an object that wants to seek information as knowledge for themselves. Logistic regression is used for describing between dependent variable and independent variable to categorical data. In logistics regression analysis, y=0 showed that students are not interested in continuing their study while y=1 showed that students are interested in continuing their study to the university. STAI characteristics of the students who most of the madrasah aliyah. look at the existing market potential, it is necessary to investigate any factors that influence students' interest to continue their education into college. one analysis can be used to model the relationship is logistic regression. from the regression results indicate that factors that affect, among others, the job of parents, parents' education, average income of parents, the students achievement and there were some brothers or sister who continue study to college. The result of logistic regression method shows that interest that the parents education, average income of parents, motivating factor.

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.
