Judul: Modal Sosial Masyarakat Pantai Tirtamaya dalam Pengembangan Ekowisata Bahari.
Abstrak: Modal sosial telah banyak menunjukkan perannya dalam membantu pengembangan suatu kawasan ekowisata, termasuk ekowisata bahari. Penelitian ini bertujuan untuk mengidentifikasi unsur-unsur modal sosial pada masyarakat Pantai Tirtamaya dan mengukur hubungan antar unsur serta pengaruhnya dalam pembentukan modal sosial dalam pengembangan ekowisata bahari, khususnya pada masyarakat Desa Juntikedokan. Metode yang digunakan adalah wawancara, observasi dan studi literatur. Hasil identifikasi unsur modal sosial di masyarakat Desa Juntikedokan menunjukkan nilai rata-rata 55, yang berarti modal sosial di desa ini termasuk kategori sedang. Analisis hubungan pengaruh nyata (T-Value) antara variabel unsur modal sosial dengan modal sosial untuk Desa Juntikedokan menunjukkan bahwa unsur jaringan sosial yang secara signifikan memengaruhi modal sosial dengan nilai 3.92. Elemen lain yaitu kepercayaan, norma, tindakan proaktif dan kepedulian terhadap orang lain dan lingkungan tidak berpengaruh nyata.

Judul: Modal Sosial Masyarakat dalam Mengembangkan Ekowisata Bahari di Pulau Pramuka DKI Jakarta
Abstrak: This study aimed to analyze the relationship of the head families characteristics with the social capital in the ecotourism development at Pramuka Island. The study also aimed to examine the relationship of head families social capital with ecotourism development at Pramuka Island. The research used the quantitative method with qualitative method support. Over all, the social capital of pramuka island community for ecotourism development at Pramuka Island was quite good. This is linked to income and education. However if look the social correlation, that shown on the level of understanding of the norm, number of people who are known with the social network. However that should likely fading the society trust, especcially in the ecotourism developing.

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.
