Abstrak: Badak Jawa adalah satwa yang termasuk sangat langka di dunia, di Indonesia hanya hidup di Taman Nasional Ujung Kulon dan terkonsentrasi di Semenanjung Ujung Kulon, namun tidak semua bagian ruang di Semenanjung Ujung Kulon dapat ditempati olah badak Jawa sebagai habitatnya. Hal itu disebabkan untuk hidupnya badak Jawa memerlukan habitat untuk mencari makan, berlindung, berkembang biak, berkubang, dan sebagainya.

Abstrak: The javan gibbon (Hylobates moloch) is endemic to Java, and is considered a critically endangered species. The information on the population status of the javan gibbon is limited and varied. The overall aim of this project is to generate closeness relation of food and sleeping trees densities with the density of javan gibbon at Gunung Halimun National Park, West Java; generate estimateion model of population; and to generate the effect of fragmentation to the density, and home range of the javan gibbon. Vegetation sampling was taken along the survey transect at four different locations.

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.
