Judul: Ekosistem agroforestry baduy
Abstrak: Diketahui bahwa agroforestry Baduy telah lama dipraktekkan, tapi sikap tertutup masyarakat membuat kegiatan ini baru sedikit yang terungkap. Oleh karena itu dilakukan penelitian yang bertu- juan mempelajari tipe agroforestry, analisis vegetasi dan sistem pemangkasan pada sistem agroforestry Baduy. Berbagai metode dilakukan dalam penelitian ini, yaitu pengumpulan data primer di lapang dan data sekunder. Hasil penelitian menunjukkan bahwa dua kegiatan agroforestry yang utama di daerah Baduy adalah perladangan dan peternakan ayam yang dikombinasi dengan kehutanan. Tipenya adalah agrisilviculture, sylvopastoral, sederhana, kompleks, tradisional dan primitif. Didalam sistem agroforestry tersebut terdapat beragam tumbuhan dengan nilai ekologi, ekonomi, dan sosial budaya yang khas. Dilakukan juga sistem pemangkasan yang merupakan kekhasan tersendiri yang berpengaruh positif terhadap produksi. Dapat disimpulkan bahwa kegiatan agroforestry Baduy telah berhasil dalam meningkatkan hasil produksi (ekonomi) dan kelestarian lingkungan hidup (ekologi).

Judul: Conservation of Baduy Dalam Cultural Landscape to  Support the Sustainability of its Agricultural Activity
Abstrak: The Baduy tribe is a tribe whose culture is still intertwined with nature and is known as a tribe that still maintains a well-preserved agricultural culture. However, the development in the vicinity and the increasing tourist activity in Baduy village poses a threat to the preservation of the culture and the sustainability of the traditional agricultural landscape. This poses a threat to the preservation of the culture, incluiding its agricultural cultural landscape. The objectives of this study are to analyze the character of the Baduy agricultural landscape, identify key elements of the agricultural landscape, and propose recommendations for landscape conservation actions to support the sustainability of Baduy Dalam agricultural culture. This research uses the method of tracing cultural history, field survey and indepth interviews, with the research stages of data inventory, analysis, and synthesis. From the results of the analysis of the landscape character, it can be seen that the key elements are an important part of forming the agricultural cultural landscape. Key elements are scattered in the Baduy Dalam area which are grouped into conservation zoning in Baduy Dalam, including physical and non-physical elements. Each element is spread out in zones that have been grouped, there are three zones for the preservation of the Baduy Dalam cultural landscape based on activities and land use, namely zone I (residential area), zone II (agricultural land) and zone III (old forest area). The area that includes these key elements must be protected and the condition of these key elements is also analyzed and the factors that influence it. The concept of preservation that is carried out is the preservation of the cultural landscape in the form of the protection of the agricultural cultural landscape which consists of zoning conservation, security, saving maintenance and preserving cultural values for the sustainability of agricultural culture in Baduy Dalam, Suku Baduy merupakan suku yang budayanya masih memanfaatkan hasil alam dan dikenal sebagai suku yang masih memegang budaya pertanian yang masih terjaga. Akan tetapi, meningkatnya perkembangan zaman membuat suku Baduy banyak dikenal orang sehingga banyak pengunjung yang datang dan ingin menyaksikan budaya yang ada. Hal ini menimbulkan acaman untuk kelestarian budaya tersebut termasuk lanskap budaya pertaniannya. Tujuan penelitian ini adalah untuk menganalisis karakter lanskap pertanian suku Baduy, mengidentifikasi elemen kunci dari lanskap budaya pertanian dan mengusulkan rekomendasi tindakan pelestarian lanskap untuk mendukung keberlanjutan budaya pertanian Baduy Dalam. Penelitian ini menggunakan metode penelusuran sejarah danbudaya, survei lapang dan wawancara, dengan tahapan penelitian pengumpulan data, analisis, dan sintesis. Dari hasil analisis karakter lanskap dapat diketahui elemen-elemen kunci yang merupakan bagian penting pembentuk lanskap budaya pertanian. Elemen-elemen kunci tersebar di kawasan Baduy Dalam yang dikelompokkan pada zonasi pelestarian di Baduy Dalam, diantaranya adalah elemen fisik dan nonfisik. Masing-masing elemen tersebar pada zona yang sudah dikelompokkan, terdapat tiga zonasi pelestarian lanskap budaya Baduy Dalam berdasarkan aktivitas dan penggunaan lahan, yaitu zona I (area pemukiman) zona II (lahan pertanian) dan zona III (kawasan hutan tua). Area yang mencakup elemen kunci ini harus dilindungi, dianalisis pula kondisi elemen-elemen kunci ini, dan faktor-faktor yang mempengaruhinya. Konsep pelestarian yang diusung yaitu pelestarian lanskap budaya berupa perlindungan lanskap

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.
