Judul: Kontribusi Pengelolaan Agroforestri Terhadap Pendapatan Rumah Tangga Petani (Studi Kasus Di Desa Sukaluyu, Kecamatan Nanggung, Kabupaten Bogor, Jawa Barat)
Abstrak: Agroforestry is a land use system which combines woody plants with agricultural crops. Various previous researches concluded that agroforestry can improve the household income of farmers. Sukaluyu Village became one of the villages that make agroforestry as a source of their economy. The research was conducted to provide information regarding the contribution of agroforestry management to the farmer households as well as information about the agroforestry system adopted by local farmers. The results of research showed that farmers implement agroforestry system who combined trees with crops and trees with medicinal plants in which land management with agroforestry systems contribute to farmer household income was 68.60%.

Judul: Kontribusi pengelolaan agroforestri terhadap pendapatan rumah tangga petani (Studi Kasus: Desa Bangunjaya, Kecamatan Cigudeg, Kabupaten Bogor, Provinsi Jawa Barat)
Abstrak: Hutan rakyat merupakan hutan yang dibangun, dikelola, dan dimanfaatkan oleh rakyat di atas tanah milik. Pada kenyataannya di lapangan, hutan rakyat tidak berwujud secara murni tetapi berwujud kebun campuran pepohonan dengan tanaman pertanian, buah-buahan dan pangan lainnya, yang dikenal atau disebut sebagai agroforestri. Agroforestri adalah sistem penggunaan lahan yang mengkombinasikan tanaman berkayu dengan tanaman tidak berkayu (kadang-kadang dengan hewan) yang tumbuh bersamaan atau bergiliran pada suatu lahan, untuk memperoleh berbagai produk dan jasa (services) sehingga terbentuk interaksi ekologis dan ekonomis antar komponen tanaman. Sistem pengelolaan agroforestri sendiri dibagi menjadi dua jenis yaitu sistem agroforestri sederhana dan sistem agroforestri kompleks. Kedua sistem agroforestri tersebut sama-sama menghasilkan beberapa komoditi seperti kayu, buah-buahan, dan tanaman pangan. Berdiri di atas wilayah seluas 11,62 km² dan dihuni 8.246 jiwa dengan kepadatan penduduk rata-rata 710 jiwa/km² (BPS, 2009), Desa Bangunjaya, Kecamatan Cigudeg, Kabupaten Bogor, Provinsi Jawa Barat menjadi salah satu desa yang menjadikan agroforestri sebagai sumber ekonominya. Berbeda dengan agroforestri yang pada umumnya menghasilkan kayu atau padi dan palawija sebagai komoditas utama, buah-buahan justru menjadi primadona di Desa Bangunjaya.

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.
