Judul: Determinan Pembelian Makanan Tanpa Label Halal Melalui Layanan Online Food Delivery pada Muslim Generasi Z
Abstrak: Manusia memiliki kebutuhan dasar, salah satunya adalah makanan. Bagi umat muslim mengonsumsi makanan halal dan baik merupakan kewajiban, namun tidak semua makanan yang dijual telah berlabel halal. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi keputusan pembelian konsumen muslim generasi Z di Jawa Barat terhadap makanan tanpa label halal melalui online food delivery. Sampel dalam penelitian ini berjumlah 100 responden yang mewakili muslim generasi Z Jawa Barat. Analisis yang dilakukan adalah analisis deskriptif dan SEM-PLS. Hasil penelitian menunjukkan bahwa pengetahuan produk halal tidak berpengaruh signifikan terhadap sikap. Review konsumen memiliki pengaruh signifikan terhadap norma subjektif. Harga dan pendapatan berpengaruh signifikan terhadap persepsi kontrol perilaku, akan tetapi kualitas produk tidak berpengaruh signifikan terhadap persepsi kontrol perilaku. Niat pembelian dipengaruhi secara signifikan oleh persepsi kontrol perilaku, sedangkan sikap dan norma subjektif tidak berpengaruh signifikan terhadap niat pembelian. Persepsi kontrol perilaku, promosi, dan niat pembelian berpengaruh signifikan terhadap keputusan pembelian makanan tanpa label halal.

Judul: The Impact of Halal Label Perception towards Purchase Decision of Imported Processed Food Products (A Case Study of Generation Z Muslim in Bogor Regency)
Abstrak: Produk makanan olahan impor kini semakin banyak beredar di Indonesia, namun belum semua produk makanan olahan impor sudah memiliki label halal. Hal ini membuat konsumen Muslim perlu meningkatkan selektivitas dalam membeli produk makanan olahan impor yang halal dan layak untuk dikonsumsi. Penelitian ini bertujuan untuk menganalisis pengaruh religiusitas, kelompok acuan, pendapatan, gaya hidup, dan persepsi label halal terhadap keputusan pembelian produk makanan olahan impor pada generasi ZMuslim di Kabupaten Bogor dengan mengambil responden sebanyak 100 responden. Metode yang digunakan dalam penelitian ini adalah analisis deskriptif dan analisis Structural Equation ModelingPartial Least Square (SEM-PLS). Hasil penelitian menunjukkan bahwa kelompok acuan, pendapatan, gaya hidup, dan persepsi label halal berpengaruh positif dan signifikan terhadap keputusan pembelian makanan olahan impor., Nowadays, imported processed food products are increasingly distributed in Indonesia, however not all of them have been halal labelled. Due to this condition, Muslim consumers need to increase selectivity in buying imported processed food products which guaranteed the halal status and suitable for consumption. This study aims to analyze the effect of religiosity, reference group, income, lifestyle, and perceptions of halal labels on purchasing decision of imported processed food products in 100 respondents of Generation Z Muslim who lived at Bogor Regency. This study used descriptive analysis method and data was analyzed using Structural Equation Modeling-Partial Least Square (SEM-PLS). The results of this study indicate that the reference group, income, lifestyle, and perception of the halal label had a positive and significant effect on purchasing decisions of imported processed foods.

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.
