Judul: Dinamika kelompok tani hutan dalam pengelolaan hutan rakyat: kasus pada kelompok tani hutan di Desa Jugalajaya, Kecamatan Jasinga, Kabupaten Bogor
Abstrak: Community forest development of is an effort to improve the welfare of society, includes forest farmers community through related businesses. One of efforts in community forest management development is establish a forest institutional. Institutional has two meanings, i.e. a set of regulations and an organization creates and oversees the implementation of these regulations. Forest Farmers Group (KTH) is part of forest institutional designed to accommodate the activities of community forest management activities from production sub-systems, product processing sub-system to product marketing sub-systems. Thus, community forests could be one of the established business units. The purposes of this research are to define the community forest management at the research site, to analyze the level of KTH dynamism and the level of dynamics influence to community forest management. To measure the level of KTH dynamism, used assessment quantification through Likert Scale models then scores categorized into grade-level category of KTH dynamism. While to identify the influence level of KTH dynamism in community forests management used Spearman Correlation Test Level. Forest management activities in Jugalajaya are conducted individually at the level of household leader. The activities were at the level of land preparation, planting, and maintenance only, while harvesting were conducted by middlemen. Cumulatively, the level of KTH dynamism KTH Mandiri Kuningsari II and II still low relatively with average score 42,63% of the expectations maximum score. It‟s due to the absence of written specific goals and action plans, so that group members have not been able for finding the ideal aim of being group. So far the activities conducted by KTH still limited to any assistance or projects from government or related institutions. This illustrates that the group has not been able to be platform of cooperation and education for forest farmers. It also describes that the dynamics of KTH has no significant influence to the community forest management in the sub-production system.

Judul: Dinamika Kelompok Tani Hutan : Kasus Kelompok Tani Hutan Rakyat dan Kelompok Usaha Perhutanan Sosial di Kabupaten Bandung, Jawa Barat.
Abstrak: Keberhasilan dan kegagalan suatu kelompok petani ditunjukkan oleh dinamika kelompok tersebut. Penelitian ini bertujuan untuk: a) menganalisis tingkat dinamika kelompok Tani hutan (KTH) dan lembaga masyarakat desa hutan (LMDH), b) menganalisis faktor individu yang memengaruhi dinamika, dan c) merumuskan strategi untuk meningkatkan dinamika KTH di hutan rakyat dan LMDH dalam program perhutanan sosial. Penelitian ini dilakukan yakni di KTH Tani Mukti di Desa Babakan Peuteuy Kecamatan Cicalengka dan LMDH Bukit Amanah di Desa Cempakamulya Kecamatan Cimaung, Kabupaten Bandung. Data dikumpulkan dengan wawancara menggunakan kuesioner dan pengamatan lapangan. Wawancara dilakukan dengan terhadap 30 responden tiap KTH/LMDH yang dipilih secara sengaja berdasarkan pertimbangan keaktifan responden dalam KTH/LMDH. Data yang terkumpul dianalisis menggunakan Model Persamaan Struktural (SEM) dengan pendekatan Partial Least Square (PLS). Dalam penelitian ini, persepsi terhadap dinamika kelompok dibagi menjadi Sembilan variabel. Hasil penelitian menunjukkan bahwa dinamika kelompok KTH Tani Mukti berada dalam kategori rendah, hal ini berarti interaksi dalam kelompok masih kurang. Sementara dinamika kelompok LMDH Bukit Amanah berada dalam kategori tinggi. Karakteristik responden yang memengaruhi dinamika kelompok KTH Tani Mukti adalah luas kepemilikan lahan dan motivasi kelompok. Dalam motivasi kelompok, terdapat tiga jenis motivasi bagi petani untuk bergabung dalam kelompok, yaitu ekonomi, sosial, dan ekologi. Sedangkan karakteristik responden yang memengaruhi dinamika kelompok LMDH Bukit Amanah adalah tingkat pendidikan, pendapatan, jumlah tanggungan keluarga, pengalaman bertani, usia, lama tinggal di desa, dan motivasi kelompok. Strategi untuk meningkatkan dinamika kelompok di KTH Tani Mukti dapat dilakukan dengan memperkuat tujuan kelompok, pembinaan dan pengembangan kelompok dan efektifitas kelompok. Sedangkan di LMDH Bukit Amanah dapat dilakukan melalui tujuan, pembinaan dan pengembangan kelompok, suasana dan efektifitas kelompok.

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.
