Judul: Analisis Perilaku Konsumen Terhadap Restoran Waroeng Taman di Kota Bogor
Abstrak: Perubahan gaya hidup masyarakat Kota Bogor akibat meningkatnya aktivitas di luar rumah menyebabkan perubahan pola konsumsi pangan dan cara makan masyarakat. Saat ini, masyarakat Kota Bogor cenderung lebih memilih untuk mengkonsumsi makanan di luar rumah, mulai dari warung makan pinggir jalan sampai restoran-restoran mewah yang menyediakan berbagai macam hidangan. Hal ini disebabkan karena semakin terbatasnya waktu untuk memasak dan mengolah makanan sendiri. Waroeng Taman sebagai salah satu restoran yang menyajikan berbagai macam hidangan, saat ini telah menjadi alternatif pilihan tempat makan yang digemari di Kota Bogor. Pada awal berdirinya, Waroeng Taman memfokuskan target pasarnya bagi konsumen rumah tangga. Namun seiring dengan perkembangannya, Waroeng Taman mengalami pergeseran target pasar dimana konsumen yang membeli ke Waroeng Taman didominasi oleh kawula muda. Keadaan tersebut merupakan tantangan dan peluang bagi pihak Waroeng Taman untuk lebih memahami keinginan konsumen. Penelitian ini bertujuan untuk mengidentifikasi karakteristik konsumen Waroeng Taman, menganalisis proses keputusan pembelian yang dilakukan konsumen Waroeng Taman, menganalisis tingkat kepentingan dan kinerja atribut serta kepuasan konsumen terhadap atribut dan pelayanan Waroeng Taman dan merekomendasikan alternatif kebijakan pemasaran berdasarkan perilaku konsumen Waroeng Taman. Metode analisis yang digunakan pada penelitian ini adalah analisis deskriptif, Importance Performance Analysis (IPA), dan analisis Costumer Satisfaction Index (CSI).

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.
