Judul: Perencanaan lnterpretasi Biota Air di Kawasan Suaka  Margasatwa Muara Angke
Abstrak: Suaka Margasatwa Muara Angke (SMMA) sebagai hutan mangrove merupakan habitat kera ekor panjang, burung-burung merandai, dan berbagai jenis biota air. Sejauh ini, sangat sedikii masyarakat yang mengetahui tentang biota air di SMMA karena belum ada program interpretasi tentang biota air. Peneliian ini bertujuan untuk menyusun rencana interpretasi biota air di SMMA. Tahaptahap perencanaan interpretasi adalah penentuan topik dan tujuan, pengumpulan data, analisis data, sintesis, dan penyusunan rencana.

Judul: Hubungan Komponen Habitat Suaka Margasatwa  Muara Angke Dan Hutan Lindung Angke Kapuk  Dengan Burung Air
Abstrak: Keberadaan burung air dalam suatu kawasan memiliki hubungan dengan komponen-kornponen pembentuk habitat. Dalam penelitian ini dipelajari hubungan beserta sebaran burung air di Suaka Margasatwa Muara Angke dan Hutan Lindung Angke Kapuk pada bagian tambak. Komponen-komponen habitat yang diukur pada setiap titik pengamatan adalah, banyaknya jenis tumbuhan, banyaknya jenis dan individu pohon dengan tinggi diatas dan dibawah 3 m, Gosentase penutupan tajuk pohon, prosentase penutupan tumbuhan bawah dan prosentase perairan terbuka, dan profil vertikal dari plot contoh yaitu banyaknya lapisan tajuk, pohon tertinggi, terendah dan rata-rata tinggi pohon berdiameter diatas dan dibawah 12 cm, rata-rata tinggi tumbuhan bawah dan tinggi bertenggernya burung air, yang mempengaruhinya.

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.
