Judul: aFaktor-faktor yang memengaruhi realisasi pembiayaan mikro syariah dan dampaknya terhadap omzet usaha nasabah (Studi kasus KJKS BMT UGT Sidogiri cabang Koja Jakarta)
Abstrak: Micro-business has a role of the national economy development. However, micro scale entrepreneurs face problems of limited capital. This study to analyze the factors affecting the amount of the financing provided BMT and their impact on bussiness turnover. This research was conducted in March-April at KJKS BMT UGT Sidogiri branch Koja Jakarta. This research used a purposive sampling technique with a total of 30 respondents. OLS analysis results proved that business asset, frequency financing, installment period, and dummy business have significantly effect on the realization of financing. Meanwhile, the factors affecting the customer’s turnover are business asset, amount of financing, business profit after financing, time duration of educational, time duration of business, and dummy business.

Judul: Analisis Dampak Pembiayaan Syariah Terhadap Perkembangan Omset Usaha Mikro Sektor Perdagangan (Studi Kasus KBMT Wihdatul Ummah Kota Bogor)
Abstrak: Usaha mikro memiliki peran penting dalam pertumbuhan ekonomi nasional. Kendala utama yang sering dihadapi oleh pelaku usaha mikro adalah keterbatasan terhadap akses modal. KBMT Wihdatul Ummah merupakan salah satu lembaga keuangan mikro syariah non bank yang memberikan fasilitas bagi pengusaha mikro untuk mendapatkan tambahan modal melalui pembiayaan mikro syariahnya. Tujuan dari penelitian ini adalah menganalisis dampak pembiayaan mikro terhadap perkembangan usaha mikro. Metode yang digunakan dalam penelitian ini adalah uji-t berpasangan dan OLS. Hasil uji-t berpasangan menunjukkan bahwa terdapat perbedaan yang signifikan omset sebelum dan sesudah diberikan pembiayaan mikro syariah. Hasil analisis dengan metode OLS menunjukkan bahwa lama usaha, jumlah aset, jumlah pembiayaan, dan berpengaruh signifikan terhadap perkembangan omset.

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.
