Judul: Pengembangan Ekowisata “Javan Rhino Study and Conservation Area” di Taman Nasional Ujung Kulon, Banten
Abstrak: Salah satu tujuan Javan Rhino Study and Conservation Area (JRSCA) yaitu mengembangkan ekoturisme sehingga perlu adanya strategi pengembangan ekowisata JRSCA. Potensi tumbuhan tersebar di berbagai tipe ekosistem, meliputi: hutan hujan tropis, hutan bakau, hutan pantai dan rawa. Potensi satwa, meliputi: badak jawa, banteng, anjing hutan, macan tutul, kancil, primata dan berbagai jenis burung. Masyarakat mendukung pengembangan ekowisata, menerima kedatangan wisatawan, dan memiliki modal sosial untuk ekowisata. Wisatawan potensial berminat terhadap ekowisata JRSCA dengan motivasi untuk memperoleh pengalaman belajar berbagai hal tentang badak jawa dan habitatnya. Pengembangan ekowisata dapat dilakukan dengan alternatif strategi, yaitu: mengembangkan produk ekowisata, mengoptimalkan promosi ekowisata JRSCA, kegiatan interpretasi ekowisata, penyediaan sarana dan peningkatan keamanan JRSCA, pengaturan jalur wisata dan peningkatan pemahaman pengelola dan masyarakat lokal.

Judul: Alternatif Rencana Pengembangan Ekowisata di Suaka Rhino Sumatera (SRS) Taman Nasional Way Kambas.
Abstrak: Suaka Rhino Sumatera (SRS) memiliki potensi keanekaragaman hayati berupa satwa endemik seperti badak sumatera (Dicerorhinus sumatranensis). Tujuan dari penelitian ini adalah menyusun rencana pengembangan ekowisata berbasis pendidikan dan penelitian di SRS Taman Nasional Way Kambas (TNWK). Objek utama daya tarik wisata ini yaitu Badak Sumatera dan beberapa jenis tumbuhan serta satwaliar potensial lainnya. Pengunjung potensial berminat untuk mengunjungi SRS dan melakukan ekowisata di SRS. Kegiatan ekowisata yang dapat dilakukan antara lain mengamati kegiatan pemeliharaan badak, fotografi, dan aksi konservasi. Hasil perhitungan nilai daya dukung PCC diperoleh sebesar 1.244 pengunjung per hari, RCC sebesar 509 pengunjung per hari, dan ECC sebesar 3 pengunjung per hari. Peningkatkan efektivitas kegiatan ekowisata di SRS perlu dilakukan melalui pengembangan zonasi, pengembangan sumberdaya manusia, pengembangan infrastruktur dan sistem informasi, serta pengembangan kegiatan dan program ekowisata.

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.
