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: Isolasi dan purifikasi inhibitor RNA helikase virus hepatitis C dari bakteriosin bakteri asam laktat S34
Abstrak: Target molecular therapy is one of method to prevent hepatitis C virus which was developed recently. NS3 Helicase/RNA helicase hepatitis C virus inhibition using inhibitory peptide are target in molecular therapy. Bacteriocin are inhibitory peptides which can inhibit hepatitis C virus through inhibition of NS3 helicase. Bacteriocin is a peptide which is produced by lactic acid bacteria. The aim of this research were to isolate and to purify bacteriocin from S34 lactic acid bacteria which has high activity to inhibit RNA helicase of hepatitis C virus. S34 lactic acid bacteria were identified using 16S RNA amplification and DNA sequencing identification of S34 lactic acid bacteria was Lactobacillus plantarum WCFS1. The bacterial growth reached logaritmic phase at 7 hours and stationary phase at 10 hours. Bacteriocin were isolated and purified by ammonium sulphate precipitation with 80% saturation, gel filtration chromatography, and characterization of bacteriocin through molecular weight analysis and measured protein concentration. Bacteriocin from S34 lactic acid bacteria were included in 2nd class bacteriocin, had 64.20 % of inhibition against RNA helicase hepatitis C virus, had molecular weight about 1.7-4.2 kDa, and specific activity in the amount of 2.84 x 106 U/mg.
