Judul: Faktor yang Memengaruhi Perilaku Konsumtif Muslimah Generasi Z terhadap Modest Fashion
Abstrak: Modest fashion merupakan salah satu sektor industri halal yang terus berkembang pesat, khususnya di Indonesia karena memiliki penduduk mayoritas muslim. Tren modest fashion yang cepat berganti saat ini mendorong perempuan muslim semakin konsumtif dalam mengonsumsi pakaian model terbaru, salah satunya muslimah Generasi Z karena cenderung memiliki pengaruh positif yang signifikan terhadap mengikuti tren yang dilihat melalui media sosial. Konsumtif atau berlebihan (israf) merupakan perilaku yang dilarang dalam Islam. Penelitian ini bertujuan mengidentifikasi faktor-faktor yang memengaruhi perilaku konsumtif muslimah Generasi Z terhadap modest fashion. Metode analisis yang digunakan adalah regresi linier berganda dengan menggunakan software SPSS 25. Sampel yang diperoleh sebanyak 100 responden. Hasil penelitian menunjukkan bahwa variabel sosial, pribadi, dan psikologis berpengaruh signifikan terhadap perilaku konsumtif muslimah Generasi Z terhadap modest fashion.

Judul: Faktor yang Memengaruhi Muslim Generasi  Z dalam Minat Beli Produk Kosmetik Halal yang Ramah Lingkungan
Abstrak: Konsumsi muslim global terhadap produk halal terus mengalami perkembangan yang berdampak pada peningkatan konsumsi kosmetik halal. Kegiatan industri yang semakin pesat saat ini juga diiringi dengan meningkatnya permasalahan lingkungan yang menyadarkan banyak pihak mengenai isu lingkungan dan menyebabkan peningkatan konsumsi akan green products termasuk produk kosmetik. Salah satu produk kosmetik halal yang ramah lingkungan adalah kosmetik merek Garnier dan Safi. Penelitian ini bertujuan mengidentifikasi karakteristik responden muslim Generasi Z dan menganalisis faktor-faktor yang memengaruhi muslim Generasi Z dalam minat beli produk halal yang ramah lingkungan. Penelitian ini menggunakan data primer dari 300 responden dengan metode analisis deskriptif dan SEM-PLS menggunakan software SmartPLS 3.3.7. Hasil penelitian menunjukkan bahwa enam dari delapan hipotesis penelitian dapat diterima dan dua lainnya ditolak. Terdapat hubungan secara langsung dan tidak langsung antar variabel penelitian., Global Muslim consumption of halal products continues to experience developments which have an impact on increasing consumption of halal cosmetics. Industrial activities that are currently rapidly increasing are also accompanied by increasing environmental problems that have made many parties aware of environmental issues and have led to an increase in consumption of green products, including cosmetic products. One of the environmentally friendly halal cosmetic products is Garnier and Safi brand cosmetics. This study aims to identify the characteristics of Muslim Generation Z respondents and analyze the factors that influence Generation Z Muslims in buying environmentally friendly halal products. This study uses primary data from 300 respondents with descriptive analysis method and SEM-PLS using SmartPLS 3.3.7 software. The results showed that six of the eight research hypotheses were accepted and the other two were rejected. There is a direct and indirect relationship between research variables.

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.
