Abstrak: Perkembangan dunia digital memunculkan media sosial yang memungkinkan penggunanya untuk melakukan transaksi di dalamnya, salah satunya social commerce TikTok. Digitalisasi mempercepat transformasi digital terutama dalam digital marketing. UMKM sebagai penyumbang PDB terbesar dalam skala internasional khususnya sektor Ekonomi Kreatif dengan sub sektor utama bidang fashion perlu diperhatikan perkembangannya karena potensial. Di samping pesatnya perkembangan digitalisasi, sebagian besar pelaku UMKM belum masuk dalam sistem digital. Penelitian ini bertujuan untuk menganalisis pengaruh short video marketing terhadap consumer brand attitude serta pengaruh consumer brand attitude dan live streaming terhadap purchase intention UMKM sektor fashion pada social commerce TikTok. Metode penarikan sampel dengan purposive sampling dan jumlah sampel yang digunakan sebesar 170 responden. Analisis data menggunakan analisis deskriptif dan Structural Equation Modeling (SEM) – PLS. Hasil pengujian membuktikan bahwa short video marketing memiliki pengaruh yang signifikan dan positif terhadap consumer brand attitude. Consumer brand attitude dan live streaming juga memiliki pengaruh yang signifikan dan positif terhadap purchase intention., The development of the digital world gave rise to social media that allowed users to make transactions on it, one of which was social commerce TikTok. Digitalization accelerated digital transformation, especially in digital marketing. MSMEs, as the largest PDB contributor, especially the Creative Economy sector with the main sub-sector in fashion, needed to pay attention to development because of potential. Despite the rapid development of digitization, most MSMEs had not yet entered the digital system. This study aimed to analyze the effect of short video marketing on consumer brand attitudes and the influence of consumer brand attitudes and live streaming on the purchase intention of SMEs in the fashion sector on TikTok social commerce.

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.
