Judul: Analysis of the Factors Influencing Consumer Purchase Decisions Warung Kopi Raja
Abstrak: Kopi merupakan salah satu hasil produk pertanian yang telah memiliki banyak peminat dan paling banyak diperdagangkan di seluruh dunia (International Coffee Organization 2015). Peningkatan tingkat produksi dan konsumsi kopi di Indonesia menyebabkan jumlah kafe dan restoran di Kabupaten Bogor juga meningkat khususnya kedai kopi sehingga memunculkan lingkungan yang kompetitif. Salah satu kedai kopi yang muncul yaitu Warung Kopi Raja yang terletak di Ciampea. Menjadi pendatang baru merupakan tantangan bagi pihak manajemen Warung Kopi Raja untuk berkembang dan bertahan dalam persaingan tersebut. Penelitian ini dilakukan bertujuan mengetahui karakteristik konsumen, mengetahui proses pengambilan keputusan pembelian konsumen, dan menganalisis faktor-faktor yang memengaruhi dalam pengambilan keputusan pembelian konsumen di Warung Kopi Raja. Metode yang digunakan pada penelitian ini menggunakan metode analisis deskriptif dan analisis faktor. Analisis deskriptif digunakan untuk menganalisis karakteristik konsumen dan proses pengambilan keputusan pembelian konsumen. Analisis faktor digunakan untuk menganalisis faktor-faktor yang memengaruhi keputusan pembelian dengan bantuan perangkat lunak Statistical Package for Social Science (SPSS) Version 26., Coffee is one of the agricultural products that has many enthusiasts and is most traded throughout the world (International Coffee Organization 2015). The increase in the level of production and consumption of coffee in Indonesia has caused the number of cafes and restaurants in Bogor Regency to also increase, especially coffee shops, thus creating a competitive environment. One of the coffee shops that emerged was Warung Kopi Raja, located in Ciampea. Being a newcomer is a challenge for the management of Warung Kopi Raja to develop and survive in this competition. This research was conducted with the aim of knowing the characteristics of consumers, knowing the process of making consumer buying decisions, and analyzing the factors that influence consumer buying decisions at Warung Kopi Raja. The method used in this study uses descriptive analysis methods and factor analysis. Descriptive analysis is used to analyze consumer characteristics and consumer buying decision making processes. Factor analysis is used to analyze the factors that influence purchasing decisions with the help of the Statistical Package for Social Science (SPSS) Version 26 software.

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.
