Judul: Social-Ecology Dynamics in Kerinci Seblat National Park: Access of Land, Agricultural Expansion, and Livelihoods (Case: Farmer's Households in Kota Baru Village, Uram Jaya District, Lebong Regency, Bengkulu)
Abstrak: Masyarakat Desa Kota Baru memiliki ketergantungan terhadap kawasan Taman Nasional Kerinci Seblat (TNKS) sehingga terus memaksa untuk melakukan kegiatan pertanian ilegal. Tujuan dari penelitian ini adalah untuk menganalisis dinamika sosial-ekologi di kawasan Taman Nasional Kerinci Seblat melalui pengkajian terhadap mekanisme akses lahan, ekspansi pertanian, dan penghidupan rumah tangga petani di sekitar kawasan. Pendekatan dalam penelitian ini adalah mix method. Hasil penelitian menunjukkan bahwa terdapat empat mekanisme akses struktural yang digunakan oleh rumah tangga petani untuk mengakses kawasan taman nasional, yaitu modal, teknologi, identitas sosial, dan pasar. Pola ekspansi pertanian yang ditemukan adalah pola berbintik dengan tipe ekspansi, yaitu waris, jual-beli, dan buka sendiri. Mekanisme akses modal dan pasar berhubungan langsung dengan pendapatan rumah tangga petani sektor ekstraksi kawasan. Namun, mekanisme akses teknologi dan identitas sosial tidak berhubungan secara langsung dengan pendapatan rumah tangga petani sektor ekstraksi kawasan., Kota Baru Village has a dependency on the TNKS area so that it continues to force its way in to carry out gricultural activities even though they are illegal. The purpose of this study is to analyze the social-ecological dynamics in the Kerinci Seblat National Park area through a deeper study of the mechanisms of land access, agricultural expansion, and livelihoods of farming households around the area. The approach in this research is mixed method. The results show that there are four structural access mechanisms used by farming households to access the national park area, namely capital, technology, social identity and market. The pattern of agricultural expansion found is a speckled pattern with the types of expansion, namely inheritance, buying and selling, and opening their own. Capital and market access mechanisms has correlated to extraction income of farmers' household. However, the mechanism of access to technology and social identity’s not directly correlated to the extraction income of farmer households.

Judul: Analisis sosial, ekonomi petani peladang di Taman Nasional Kerinci Seblat dan petani peladang peserta transmigrasi di Propinsi Jambi
Abstrak: Berbagai upaya telah dilakukan Pemerintah Daerah Propinsi Jambi untuk mengatasi perladangan dan perambahan hutan di Taman Nasional Kerinci Seblat diantaranya Merelokasikan petani peladang kedaerah asal, Program hutan kemasyarakatan dan Program Transmigrasi, namun program ini. menghadapi tantangan dimana sebagian petani kembali lagi berladang dalam kawasan TNKS. Dalam penelitian ini ada 6 kategori rumah tangga petani yang diteliti yakni 1). Rumah tangga petani peladang yang direlokasikan namun kembali berladang dalam TNKS (RTP.1), 2). Rumah tangga petani peladang yang direlokasikan tidak kembali berladang dalam TNKS (RTP.2), 3). Rumah tangga petani yang tidak berladang dan tidak menanan kulit manis (RTP.3), 4). Rumah tangga petani peladang ikut program hutan kemasyarakatan (RTP.4), 5). Rumah tangga petani peladang ikut transmigra- si yang menetap (RTP.5), 6). Rumah tangga petani peladang ikut program transmigrasi yang kembali ke daerah asal (RTP.6). Tujuan penelitian adalah 1). Mengidentifikasi dan menghitung kondisi sosial ekonomi dari 6 kategori rumah tangga petani yang diteliti, 2). Mempelajari per- sepsi masyarakat sekitar TNKS terhadap keberadaan TNKS, 3). Mempelajari kontribusi sumber pendapatan dari 6 rumah tangga petani yang diteliti, 4). Menganalisa pengaruh faktor sosial ekonomi terhadap perluasan perladangan dalan TNKS.

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.
