Judul: Kajian Ekologi-Ekonomi Sumberdaya Hutan Mangrove Di Desa  Talise, Kabupaten Minahasa, Sulawesi Utara
Abstrak: Desa Talise, Kabupaten Minahasa memiliki luas hutan mangrove sebesar 62 hektar dimana tersebar di Dusun 1 (Kp Talise),Dusun II (Kp Tambun) dan Dusun III (P. Kinabuhutan). Hutan mangrove ini hanya terdiri dari 2 famili yaitu Avicenniaceae dengan jenis Avicennie marina dan nama lokalnya api-api; Rhizophoracea dengan jenis Rhizophora mucronaia, R apiculaia, R.siylosa, Rruguiera cylindrica, R. gymnorrhiza dengan nama lokal berturut-turut lolaro,lolaro merah, lolaro putih, ting putih dan makurung laut.

Judul: Kajian Pengelolaan Mangrove Berbasis Masyarakat Di Desa Likupang IT, Kabupaten Minahasa Utara, Provinsi Sulawesi Utara
Abstrak: Desa Likupang II merupakan wilayah pesisir dengan sumberdaya hutan mangrove yang cukup beragam spesiesnya, dewasa ini diperhadapkan pada masalah tingkat eksploitasi yang berlebihan serta lemahnya persepsi dan kesadaran masyarakat akan pentingnya ekosistem mangrove. Tujuan penelitan ini adalah (1) Mengetahui potensi hutan mangrove; (2) Mengetahui tingkat partisipasi masyarakat dalam upaya pelestarian hutan mangrove; dan (3) Mengetahui strategi-strategi apa saja yang berperan dalam tingkat partisipasi masyarakat dalam upaya pelestarian hutan mangrove. Penelitian ini dilakukan di Desa Likupang II Kabupaten Minahasa, Provinsi Sulawesi Utara. Pengumpulan data primer dilakukan langsung di lapangan dengan teknik survei melalui wawancara dengan respond en dan juga menggunakan kuesioner sedangkan data mangrove dilakukan dengan pengamatan dan pendataan langsung di lapangan dan di laboratorium. Untuk data sekunder diperoleh dari instansi-instansi di daerah. Analisis dilakukan dengan menggunakan metode kualitatif dan kuantitatif, Analisis potensi hutan mangrove digunakan pendekatan secara ekologi kuantitatif; Untuk melihat hubungan karakteristik masyarakat dengan tingkat partisipasi dalam pengelolaan ekosistem mangrove menggunakan Pricipal Component Analisys (PCA); dan untuk strategi pengelolaan ekosistem mangrove tersebut menggunakan analisis SWOT (Strength, Weakness, Opportunity, and Threat)…dst

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.
