Judul: Analisis Dampak Penataan dan Faktor-Faktor yang Memengaruhi Omset Pedagang Kakilima di Kota Bogor (Periode Tahun 2012- 2013)
Abstrak: Pedagang kakilima sebagai sektor informal sering menjadi permasalahan perkotaan yang tidak ada habisnya karena kelebihan dan kekurangan yang dimilikinya. Keberadaan Pedagang kakilima seringkali memberikan dampak yang negatif seperti mengurangi keindahan, kebesihan dan estetika suatu lokasi, mengganggu kelancaran arus lalu lintas dan arus pejalan kaki serta mengganggu fungsi prasarana kawasan perkotaan. Disamping sebagai pembawa masalah, sebenarnya ada sisi lain Pedagang kakilima yaitu sebagai penyelamat ekonomi rakyat, menyerap tenaga kerja, mendorong bergeraknya perekonomian daerah dan sumber retribusi. Penataan Pedagang kakilima dilakukan sebagai solusi untuk menekan dampak negatif dan mendorong dampak positif. Penelitian ini dilakukan untuk melihat dampak penataan pedagang kakilima dan faktor-faktor yang memengaruhi omset pedagang. Uji-t berpasangan menunjukkan bahwa rata-rata omset sebelum penataan pedagang kakilima dengan setelahnya tidak jauh berbeda. Berdasarkan uji regresi linear berganda, faktor yang berpengaruh secara signifikan terhadap omset adalah usia, lama usaha, jam operasional dan jumlah pembeli.

Judul: Analisis Dampak Relokasi Pedagang Kakilima (PKl) di Blok G Pasar Tanah Abang Jakarta Pusat (Periode Tahun 2013 – 2014)
Abstrak: A policy to control the street vendor by Jakarta Provincial Government start to become priority. One that has been done is relocating street vendors on the road around Tanah Abang Market to Block G. Now the road around Tanah Abang Market does not have a traffic jam and clean from street vendors, but this relocation also provide impact on revenue of street vendors. In this study the impact of the relocation analyzed with t-paired test, and factors that influence income before and after relocating street vendors were analyzed using multiple linear regression. This study used the primary data from the interview. The results from the analysis showed that after relocation the revenue was decline amounted to 99 persen of revenue before being relocated. This declining revenue is caused by slack of buyers that come to block G. Factors that influence income only turnover. Other factors such as capital, the long effort, the working hours per day, the age of the trader, gender, education, and the cost of daily work does not have an effect on income.

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.
