Judul: Tinjauan Kemandirian Pada Dua Kelompok Tani Berbeda Kelas Kemampuan (Studi Kasus Pada Dua Kelompok tani di Desa Muarajaya, Kecamatan Caringin, Kabuapaten Bogor, Propinsi Jawa Barat)
Abstrak: Memberi perhatian terhadap masyarakat pedesaan mengandung arti penting, bukan hanya disebabkan sebagian besar penduduk Indonesia berada di daerah pedesaan, melainkan karena penyadari kedudukan dan peran desa sebagai basis ketahanan politik, ideologi, sosial, ekonomi, budaya serta pertahanan keamanan nasional. Salah satu upaya untuk membangun masyarakat desa melalui pemanfaatan sumberdaya yang ada pada mereka, agar kelak dapat meningkatkan pendapatannya adalah dengan mengintegrasikan masyarakat desa ke dalam proses pembangunan.

Judul: Peranan Kepala Desa dalam Pembangunan Masyarakat Desa Studi Kasus di Dua Desa di Kabupaten DT II Bogor Propinsi Jawa-Barat
Abstrak: Penelitian ini bertujuan untuk mempelajari ada atau tidak adanya pengaruh peranan kepala desa dengan pembangunan masyarakat khususnya yang menyangkut kemandirian,sehingga apakah benar bahwa kepala desa di dalam pembangunan masyarakat dimasa-masa yang akan datang peranannya masih penting; dan untuk mempelajari memudarnya sendi-sendi lembaga tradisional itu dipengaruhi oleh kurang berpihaknya kepala desa kepada masyrakat atau oleh semakin meningkatnya transformasi informasi di pedesaan.

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.
