Judul: Proses migrasi dan dinamika kebudayaan masyarakat migran Madura : Studi kasus masyarakat migran Madura Kelurahan Baranangsiang Kecamatan Bogor Timur Kota Bogor Propinsi Jawa Barat
Abstrak: Pembangunan yang tidak seimbang dan disparitas antar daerah menyebabkan perpindahan penduduk dan perubahan arahnya pada gilirannya dapat menimbulkan masalah baik di daerah yang ditinggalkan maupun daerah yang dituju. Daya tarik kota, kesempatan memperoleh pendidikan, wiraswasta dan penawaran jasa lainnya, sebagai bagian dari proses modernisasi, antara lain merupakan komponen yang dapat memperbesar arus perpindahan baik untuk tujuan menetap, sementara atau mungkin perpindahan sirkuler. Umumnya proses migrasi tersebut juga disertai dengan proses penyesuaian atau adaptasi baik fisik, sosial maupun budaya. Masyarakat dengan etnik tertentu yang melakukan migrasi ke suatu tempat dengan membawa budaya yang berbeda akan mengalami proses belajar kebudayaan sehingga kebudayaan masyarakat migran tersebut dapat diterima oleh masyarakat lain atau masyarakat tersebut yang menyesuaikan diri terhadap kebudayaan masyarakat migran serta berusaha mempelajari kebudayan lain. Proses belajar kebudayaan tersebut akan berpengaruh terhadap perubahan pola sikap, pola tindak dan pola sarana masyarakat migran itu sediri ataupun masyarakat setempat. Penelitian ini bertujuan (1) Mengidentifikasi alasan bermigrasi yang dilakukan oleh masyarakat migran Madura yang berada di Kelurahan Baranangsiang, Kecamatan Bogor Timur, Kota Bogor, Propinsi Jawa Barat, (2) Mengkaji sejauh mana interaksi sosial yang terjalin antara masyarakat migran Madura dengan masyarakat setempat, (3) Mengkaji sejauhmana perubahan wujud kebudayaan yang terjadi pada masyarakat migran Madura. ...

Judul: Diaspora Madura: Analisis Modal Sosial Dalam Usaha Sektor Informal Oleh Migran Madura di Kecamatan Tanah Sareal, Kota Bogor, Jawa Barat
Abstrak: Madurese is one of the ethnic in Indonesia which has a high level of mobility. The distinctive feature of their migration is affiliation patterned chained migration. In the destination area, Madurese migrants developed the bussines in informal sector, that is scrap trading bussines. Social capitals played a role in that bussines, so it grew among Madurese migrants only. Social capital consisted of networks, trust and norms. Madurese migrants network was narrow, but the most network nodes involved in the acquisition of raw materials and capital was work partner and Madurese migrants association. The trust level of Madurese migrants was low, because of the trust well done with Madurese only, while less with local society. The vital rules that must be obeyed by Madurese migrants in the bussines in informal sector was mutual respect among traders. It needed to prevent conflicts that could reduce the solidarity among Madurese migrants. But although the Madurese migrants had a limitation in terms of financial and human capital, their bussines still could grow and develop among Madurese migrant caused of social capital they had.

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.
