Judul: Affecting Factor of Local Community Participation in Mangrove Forest Conservation (Case Study in Kecamatan Teluk Ambon Baguala, Kodya Ambon)
Abstrak: Hutan mangrove merupakan salah satu sumberdaya alam yang sangat penting bagi kehidupan manusia. Sejak dulu diketahui bahwa hutan mangrove mempunyai fungsi ganda antara lain fungsi ekologis dan fungsi ekonomis, yang keguanaannya telah dimanfaatkan secara tradisional oleh sebagian besar masyarakat pesislr., The purposes of this research are to know the extent of local community participation in mangrove forest conservation, afecting factors of local community participation, relationship between internal factors and the extent of partiCipation, and relationship between external factors and the extent of local community partiCipation in mangrove forest conservation.

Judul: Studi Faktor-Faktor Sosial Ekologi dalam Pengelolaan Ekosistem Mangrove Berbasis Masyarakat (Studi Kasus Desa Kartika Jaya dan Desa Wonosari Kecamatan Patebon, Kabupaten Kendal, Provinsi Jawa Tengah)
Abstrak: This study was conducted to determine the typology of mangrove and links between social conditions and community participation in mangrove ecosystem in the conservation area of Kartika Jaya and Wonosari village, District Patebon, Kendal. This research has been conducted with direct observation in the field and interviews with 30 persons in every village. The result from observation of ecological mangrove condition show that typology of mangrove in both area are dominated by Avicennia marina with good condition, mangrove density range is about 1067-1178 ind/ha and 1622-2000 ind/ha in accordance with the Decree of the State Minister for the Environment No. 201 Year 2004. Analysis of Principal Component Analysis (PCA) results that the social factors affecting the conservation in Kartika Jaya villages are community participation in mangrove planting, knowledge about the function of mangrove ecosystems, the distance to the ecosystem, and type of job. While the determined social factors in Desa Wonosari are community participation in mangrove planting as well, knowledge about functions and types of mangrove, the abrasion experience, and home distance.

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.
