Judul: Analisis Efektivitas Live Streaming dan User-Generated Content UMKM Sektor F&B pada Platform Tiktok Berbasis AISAS Model
Abstrak: Tingginya tingkat penetrasi internet di Indonesia yang digunakan untuk mengakses media sosial dan berbelanja online mendorong munculnya trend social commerce. Tiktok merupakan social commerce yang paling banyak digunakan di Indonesia sehingga dapat dimanfaatkan oleh pelaku UMKM sektor F&B. Tiktok juga memiliki fitur yang dapat digunakan sebagai strategi promosi yaitu fitur live streaming dan user-generated content. Model AISAS digunakan untuk menganalisis perilaku konsumsi akibat peran dari internet seperti perilaku konsumsi melalui Tiktok Shop. Penelitian ini bertujuan untuk mengetahui karakteristik pengguna Tiktok serta pengaruh live streaming dan user-generated content berbasis AISAS model. Metode analisis yang digunakan adalah SEM-PLS untuk mengetahui pengaruh antar variabel berdasarkan data yang didapat dari 263 sampel. Hasil dari penelitian ini adalah live streaming dan user-generated content memiliki pengaruh signifikan terhadap attention, interest, dan search; attention, interest, dan search memiliki pengaruh signifikan terhadap action; dan action memiliki pengaruh signifikan terhadap share.

Judul: The Effect of Short Video Marketing and Live Streaming on Purchase Intention on Social Commerce TikTok MSME Fashion Sector
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. The sampling method was purposive sampling, and the number of samples used was 170 respondents. Data analysis used descriptive analysis and Structural Equation Modeling (SEM) - PLS. The test results proved that short video marketing had a significant and positive effect on consumer brand attitudes. Consumer brand attitude and live streaming also had a significant and positive influence on purchase intention.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
