Judul: Persepsi Dan Respon Petani Terfiadap Industri Besar Di Perdesaan (Kasus Desa Dawuan Tengah, Kecamatan Cikampek, Kabupaten Karawaag, Propinsi Jawa Barat)
Abstrak: Pertumbuhan ekonomi lndonesia yang meningkat dewasa ini, di mana sektor industri merupakan penyumbang terbesar dalam pembentukan Produk Dolnestik Bruto (PDB) dalam sepuluh tahun terakhir ini. Hal ini terjadi disebabkan peningkatan standar mutu kehidupan rakyat yang semakin membaik dengan disertai dukungan pemerintah di sektor riil dengan berbagai deregulasi yang memacu kenaikan investasi, baik oleh pihak asing (PMA) maupun oleh pihak dalam negeri

Judul: Analisis kepuasan petani padi pada produk peptisida spontan 400 SL PT. Agricon kasus petani padi di Kecamatan Sukamandi Jawa Barat
Abstrak: Indonesia merupakan negara agraris yang menitikberatkan pembangunannya pada sektor pertanian. Sektor pertanian memiliki peranan sangat penting dalam perkembangan perekonomian nasional Indonesia, hal ini ditunjuk dengan adanya kontribusi sektor pertanian dalam pembentukan Produk Domestik Bruto (PDB). Data BPS menunjukkan PDB sektor pertanian pada tahun 2006 tumbuh 4,12 persen sebagai pertumbuhan tertinggi setelah masa pemulihan krisis ekonomi, selain itu juga kontribusi sektor pertanian terhadap pertumbuhan penyerapan tenaga kerja pada tahun 2005 sebesar 2,97 persen lebih tinggi dibanding sektor non-pertanian (0,04 persen). Salah satu propinsi yang mendominasi penyerapan tenaga kerja disektor pertanian yakni Jawa Barat. Menurut BPS, sampai akhir Februari 2007 dari 14,99 juta orang yang bekerja di Jawa Barat 29,2 persennya atau 4,37 juta orang bekerja di sektor pertanian.

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.
