Judul: Analisis Akses Masyarakat terhadap Sumberdaya Hutan di Kawasan Taman Nasional (Kasus Taman Nasional Gunung Halimun Salak, Kec. Pamijahan, Bogor, Jawa Barat).
Abstrak: Keresahan yang muncul pada masyarakat akibat adanya kebijakan Taman nasional yang menyebabkan perubahan kesempatan akses dan pemanfaatan kawasan Gunung Halimun Salak. Perubahan akses yang terjadi berhubungan dengan sistem penghidupan masyarakat sehingga memunculkan berbagai respon dari masyarakat akibat dari kebijakan tersebut. Penelitian ini menggunakan pendekatan survei dan didukung oleh data kualitatif berupa wawancara mendalam. Responden terdiri atas 45 orang, pemilihan responden melalui metode purposive. Hasil penelitian ini menunjukkan bahwa masyarakat merasa tidak diberikan akses masuk hutan dan tidak dapat memanfaatkan sumberdaya hutan yang ada oleh pihak balai Taman Nasional Gunung Halimun Salak.

Judul: Analisis Relasi Sosial antara Warga Masyarakat dengan Para Pemangku Kepentingan Taman Nasional Gunung Halimun Salak Terkait Akses Sumberdaya Hutan Lokapurna
Abstrak: The objectives of this research is, firstly, to analyze the history and dynamics of the access of local community over Lokapurna’s forest area. Secondly, to analyze the effect of changing social relations between local community and the stakeholders of Lokapurna’s forest of the Gunung Halimun Salak National Park. A survey method supported with qualitative data is applied. The results show that, first, up to present, the governance regime and property right of Lokapurna’s forest has been changing three times. Initially, the Lokapurna’s forest classified as protection forest of common pool state property, then changes to production forest of common pool private property, and lastly became conservation forest or national park of common pool state property. Second, the social relations between local community and their stakeholders are classified as “marginal”. The local community viewed the opportunity of cooperation and threat from their stakeholder as medium level

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.
