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: Sustainable Apparel Product Purchase Decisions on Indonesian Gen Z and Millennial Women Consumers
Abstrak: Fashion trends continue to change, sustainable and fast fashion brands continue to compete to provide diverse choices for consumers. This study aims to: (1) identify the characteristics of Indonesian Gen Z and millennial women consumers of sustainable apparel products, (2) analyze the influence of sustainable product attributes and marketing factors on sustainable apparel purchasing decisions (3) analyze the influence of individual and social factors on sustainable apparel purchasing decisions using the theory of planned behaviour. The sample in this study was 77 respondents selected by convenience sampling technique. Data analysis was carried out using the SEM-PLS method and descriptive analysis. The results showed that individual factor perceived behavioural control and social factor subjective norms had a positive and significant effect, sustainable product attributes, and marketing factors had a positive but not significant effect, and individual factors attitude had a negative but weak and insignificant effect on purchasing decisions for sustainable apparel products., Tren feysen terus berganti, brand sustainable dan fast fashion terus bersaing untuk memberikan pilihan yang beragam bagi konsumen. Penelitian ini bertujuan untuk: (1) mengidentifikasi karakteristik konsumen wanita produk pakaian berkelanjutan gen Z dan milenial Indonesia, (2) menganalisis pengaruh atribut dan pemasaran produk berkelanjutan terhadap keputusan pembelian pakaian berkelanjutan, dan (3) menganalisis pengaruh faktor individu dan sosial terhadap keputusan pembelian pakaian berkelanjutan menggunakan variabel theory of planned behavior. Sampel pada penelitian ini berjumlah 77 responden yang dipilih dengan teknik convenience sampling. Analisis data dilakukan menggunakan metode SEM-PLS dan analisis deskriptif. Hasil penelitian menunjukkan bahwa faktor individu pengendalian perilaku dan faktor sosial norma subjektif berpengaruh positif dan signifikan, faktor atribut dan pemasaran produk berkelanjutan berpengaruh positif namun tidak signifikan dan faktor individu sikap berpengaruh negatif namun lemah dan tidak signifikan terhadap pengambilan keputusan pembelian produk pakaian berkelanjutan.

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.
