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: Pengaruh Persepsi Label Halal terhadap Keputusan Pembelian Produk Makanan Beku oleh Konsumen Muslim Kabupaten Bogor
Abstrak: Perilaku konsumsi pangan masyarakat Indonesia yang berubah menjadi makanan beku mengakibatkan terjadinya peningkatan konsumsi makanan beku sebanyak 17 persen di tahun 2020. Sejak pandemi, makanan beku menjadi pilihan konsumsi paling populer bagi 55 persen masyarakat Indonesia sehingga penjualannya di tahun 2021 mencapai 2,02 miliar USD. Menurut LPPOM MUI, makanan beku memiliki titik kritis kehalalan sehingga berpotensi menjadi makanan haram kemudian masih terdapat produk makanan beku yang beredar di masyarakat belum memiliki sertifikat halal. Penelitian ini bertujuan untuk mengidentifikasi karakteristik dan persepsi konsumen muslim mengenai keberadaan label halal dalam produk makanan beku serta menganalisis faktor-faktor yang memengaruhi keputusan pembelian terhadap produk makanan beku oleh konsumen muslim Kabupaten Bogor. Penelitian ini dilakukan di Kabupaten Bogor dengan mengambil sampel sebanyak 100 responden. Metode yang digunakan dalam penelitian ini yaitu analisis deskriptif dan analisis Structural Equation Modeling-Partial Least Square (SEM-PLS). Hasil penelitian menunjukkan bahwa harga, pendapatan, gaya hidup, dan kelompok acuan berpengaruh secara positif dan signifikan terhadap keputusan pembelian produk makanan beku., Consumer behavior changes have resulted in increased consumption of frozen food to 17 percent in 2020. Since pandemic, frozen food became the most popular consumption choice by 55 percent of the society with sales in 2021 reaching 2.02 billion USD. Based on LPPOM MUI, frozen food has critical points of halalness that can potentially become haram food and there are frozen foods in the public distribution without halal certificates. The research aims to identify the characteristics and perceptions of Muslim consumers regarding the existence of halal labels of frozen food products and analyze the factors that influence purchasing decisions for frozen food products by Muslim consumers in Bogor Regency. The research was conducted in Bogor Regency using sample of 100 respondents. The methods used are descriptive analysis and Structural Equation Modeling-Partial Least Square (SEM-PLS) analysis. The results of the research indicate that price, income, lifestyle, and reference groups have a positive and significant effect on purchasing decisions for frozen food products.

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.
