Judul: Distribusi Pendapatan dan Persepsi para Pihak Pengelola dalam Pengusahaan dan Pemanfaatan Hutan Rakyat di Desa Lengkong, Kecamatan Lengkong, Kabupaten Sukabumi
Abstrak: Hutan rakyat memiliki peran yang sangat penting dalam pemenuhan kebutuhan bahan baku kayu di Indonesia sehingga kelestariannya harus tetap terjaga. Penelitian ini bertujuan untuk mengetahui tahapan-tahapan pengelolaan dan pemanenan kayu di hutan rakyat, distribusi pendapatan yang diterima oleh pihak pengelola hutan rakyat, dan persepsi petani hutan rakyat terhadap penerimaan pendapatan, kelestarian hutan rakyat, dan perlunya perbaikan hutan rakyat kedepannya. Tahapan pemanenan kayu dihutan rakyat tergolong sederhana yaitu meliputi tahapan penebangan, penyaradan, pemuatan, pengangkutan dan pembongkaran. Pemanenan kayu sepenuhnya diserahkan kepada tengkulak sehingga tengkulak memiliki peran terbesar dalam pemanenan kayu hutan rakyat. Persentase distribusi pendapatan bersih yang diterima oleh petani dan tengkulak cukup seimbang masing-masing sebesar 30.77 % dan 29.71 %. Persepsi petani terhadap penerimaan pendapatan, kelestarian hutan rakyat dan perlunya perbaikan hutan rakyat berada pada rentang 3.41-5.00 dalam skala likert atau berpersepsi baik dan sangat baik. Hasil penelitian ini menunjukkan bahwa distribusi pendapatan dapat dianggap adil dan petani menunjukkan persepsi kepuasan akan pendapatan yang diterima sehingga hutan rakyat berpeluang untuk lestari.

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.
