Judul: Kemampuan anggota kelompok dalam pengelolaan hutan rakyat di Desa Tegal Waru, Kabupaten Bogor, Provinsi Jawa Barat
Abstrak: Community forest is one alternative to solve problems about unbalance supply-demand on nature forestwood and also poverty around forest area that enhancing high pressure on the forest in Indonesia. The sustainability of community forest management depends on the ability of forest group member to manage the community forest that must have been gained through learning process. This thesis inquires into farmer’s learning process in community forest management, in order to test how external and internal factors influenced ability of forest group member to manage the community forest. The study used explanatory research design with survey method on model community forest area development in Tegal Waru village, Ciampea Sub District, Bogor Regency of West Java. The research was conducted from Februari to December 2012. The data were analyzed descriptively and using multiple regresion method. The findings of the study are: (1) farmer planning ability influenced by farmer’s total income, length time involved in community forest programme, and social norms existing among forest group members; (2) farmer self-organizing ability influenced by number of course attended by farmer, quality of extension material, social norms existing among forest group members, (3) farmer ability to implement influenced by number of course attended by farmer and learnerassistant ability to communicate in the farmer’s learning process; and (4) farmer ability to supervise influenced by farmer’s total income, and production process organization in community Forest.

Abstrak: Community-based forest management has been proved to be able to prevent forest degradation at some locations. So that, to sustain community forest it is important to consider social capital of community in forest management. The purpose of this study is to find out the farmer group activity and the management organization also to identify and assess individual characteristics and social capital of farmer group. This study was conducted at the Damarwulan Village, Keling District, Jepara Regency on April 2014 using survey methods from 30 farmers. Data collected using observation, interview, documentation, and technics analyzed descriptively. Based on the assessment, the individual characteristics of farmers was in the medium category, while the social capital was at the high level. Individual characteristics that significantly correlated to the elements of social capital based on Spearman correlation were non-formal education, formal education, land area, and period of residential. Individual characteristics that significantly correlated to the social capital level were formal and non-formal education, period of residential.

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.
