Judul: Pengaruh Taman Nasional Gunung Merapi terhadap strategi nafkah masyarakat desa Ngargomulyo
Abstrak: Taman Nasional Gunung Merapi merupakan salah satu kawasan pelestarian alam yang menggunakan manajemen zonasi. Hal ini banyak memberikan pengaruh terhadap masyarakat desa sekitar kawasan salah satunya adalah Desa Ngargomulyo. Perubahan status hutan menjadi taman nasional secara tidak langsung mengubah strategi nafkah masyarakat Desa Ngargomulyo. Strategi nafkah bukan hanya sebatas kegiatan mencari nafkah namun sebagai cara hidup. Penelitian dilakukan dengan metode survey dan analisis dilakukan berdasar pada data kuantitatif yang didukung dengan data kualitatif deskriptif. Hasil penelitian menunjukkan bahwa Desa Ngargomulyo berada dalam zona tradisional TNGM, dimana hutan yang berada di desa tersebut semula merupakan hutan lindung di bawah kelola Perum Perhutani. Masyarakat masih dapat ikut memanfaatkan sumberdaya hutan seperti mengambil rumput, menanam, dan menyadap. Namun setelah mengalami perubahan status, masyarakat pun mengalami perubahan. Salah satunya adalah mengalami perubahan pola penguasaan lahan. Hal ini membawa masyarakat ke perubahan strategi nafkah. Karena pendapatan dari sektor pertanian mengalami penurunan sehingga masyarakat harus memiliki alternatif lainnya yaitu beternak dan berdagang., Gunung Merapi National Park (GMNP) is a conservation area which has zonations as its management. It gives effects to rural people around national park, Desa Ngargomulyo is one of them. The change of the status of the forest which became a national park undirectly change the livelihood strategy that community of Desa Ngargomulyo have. Livelihood strategy is not regarded as a funding activity but more as means of living. This research is conducted with survey method and analyze is based on quantitative data and supported by descriptive qualitative.The result of this research shows that community of Desa Ngargomulyo is located in the traditional zone of GMNP, which its forest war primarily a protected forest under management of Perum Perhutani. The communitystill allowed to take advantages from the forest such as taking grasses for their livestock, planting, and rubber tapping. But after the national park management, the people also affected. The community suffered changing pattern of land tenure and it lead the community to change of livelihood strategy. Because the income from farm sector is decrease, they had to have other alternatives, they are trading and farming

Judul: Dampak Perluasan Taman Nasional Gunung Gede Pangrango terhadap Strategi Nafkah Rumahtangga Petani Desa Ciputri
Abstrak: The purpose of this research is to analyze land tenure situations at Ciputri Village before and after the expansion of Gunung Gede and Pangrango National Park; and to analyse the impact of national park expansionto the farmer’s livelihood strategy. The research applied a quantitative approach supported by qualitative data. Quantitative data obtained through structured questionnaires to 30 household’s repondents. The qualitative approach applied observation instrument, in-depth interviews, and secondary document collections. The results are, first, the expansion of TNGGP significantly change the tenurial structure of Ciputri’s farmers. Before the expansion, all farmers’ respondents operate land at a minimum of 2,000 m2 of land. However, after the expansion, most of the farmers or 21 out of 30 respondent fall into landless farmers (or tuna kisma). Second, the land tenure changes,furthermore, affect significantly the livelihood strategy of the farmers’ respondent. Before the expansion of TNGGP, the livelihood of all respondent are only on agriculture as farmer operator. However, after the expansion, the livelihood of the farmers changes dramatically. As much as 22 out of 30 respondent engage in two jobs for their livelihood such as work as daily farm labor and various daily service work. The others, 6 respondent, engage in three to four jobs for their livelihood such as work as daily farm labor, smallholder farmers, and various type of daily service work in the village.

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.
