Judul: Analysis of Planned Behavior in Live Streaming Shopping Towards Purchase Intention (Case Study: TikTokShop Account @louissescarlettfamily)
Abstrak: YASMIN RAHIMA JAZULI. Analisis Planned Behaviour Pada Live Streaming Shopping Terhadap Purchase Intention (Studi Kasus: Akun Tiktokshop @louissescarlettfamily). Dibimbing oleh ANNY RATNAWATI dan LINDA KARLINA SARI. Perilaku konsumen berubah dengan cepat terutama dengan adanya live streaming shopping di era digital, sehingga pelaku usaha harus cepat beradaptasi. Penelitian ini menggunakan Theory of Planned Behavior (TPB) untuk menganalisis pengaruh sikap, norma subjektif, dan persepsi kontrol perilaku terhadap minat pembelian. Data dikumpulkan melalui kuesioner online dari 100 penonton live streaming TikTok Shop (@louissescarlettfamily) dan diolah menggunakan SEMPLS. Hasil menunjukkan bahwa semua variabel TPB berpengaruh positif signifikan terhadap minat pembelian konsumen. Implikasi manajerial yang disarankan mencakup peningkatan interaksi real-time, informasi produk yang mendalam, dan promosi khusus selama live streaming.

Judul: Analisis Live Streaming Shopping TikTok terhadap Customer Trust dan Customer Engagement serta Dampaknya pada Purchase Intention
Abstrak: Pandemi Covid-19 menyebabkan pengguna media sosial di Indonesia meningkat. Adanya peningkatan pengguna media sosial menjadikan peluang bagi pelaku usaha untuk memasarkan bisnisnya. TikTok Shop merupakan salah satu scommerce yang memudahkan para penggunanya untuk berbelanja pada aplikasi tersebut tanpa harus berganti aplikasi. Salah satu fitur yang dimiliki TikTok Shop adalah Live Streaming. Konsumen masih belum sepenuhnya percaya dengan toko online karena maraknya kasus penipuan. Oleh karena itu, penelitian ini bertujuan untuk menganalisis live streaming shopping terhadap customer trust, customer engagement, dan purchase intention terhadap masyarakat Indonesia. Metode pengambilan sampel menggunakan purposive sampling yang melibatkan 647 responden. Pengolahan data pada penelitian ini menggunakan SEM-PLS. Hasil yang didapatkan adalah live streaming shopping memiliki pengaruh positif signifikan terhadap customer trust, customer engagement, dan purchase intention.

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.
