Kitsch dalam Iklan TV Komersial dan Selera Konsumer Indonesia

Iklan TV komersial memiliki hubungan timbal Balik dengan selera konsumer. Penelitian mengenai iklan TV bermuatan kitsch, yang sering dikaitkan dengan selera rendah ini, mencoba menjawab bagaimana gambaran selera masyarakat konsumer Indonesia pada tahun 2015. Metode yang digunakan adalah metode lintas disiplin dengan pendekatan Cultural studies. Penelitian ini menguraikan gambaran selera massa konsumer Indonesia sebagai dampak dari tayangan iklan TV komersial. Dengan mengambil sampel “Iklan Biji Selasih Serbuk Panas Dalam Bintang Toedjoe”, didapati bahwa iklan tersebut mengandung unsur budaya global yang bercampur (hibrid) dengan budaya lokal dan mitos populer khas Indonesia. Hasil penelitian ini juga menunjukkan bahwa selera masyarakat Indonesia, terutama kelas menengah bawah, sangat terkait dengan karakter manusia Indonesia yang memiliki naluri berkesenian yang tinggi, suka pamer, percaya tahayul, mudah dipengaruhi oleh budaya dari luar, dan bersifat hipokrit

<i>In Vitro</i> Biocompatibility of Hydrogel Polyvinyl Alcohol/<i>Moringa oleifera</i> Leaf Extract/Graphene Oxide for Wound Dressing

Hydrogel-based wound dressings are often chosen for healing diabetic foot ulcers (DFU) in combination with herbal extracts. Moringa oleifera leaf (MOL) extract is a potent herb containing antimicrobial and anti-inflammatory bioactive substances. In this work, wound dressings based on polyvinyl alcohol (PVA), MOL extract, and graphene oxide (GO) were developed for DFU wound dressing. The PVA/MOL/GO hydrogel was synthesized using four cycles of a freeze–thaw process with varying concentrations of MOL extract. All hydrogels showed a water content of 83–88% and an equilibrium swelling ratio between 155–171%. After degradation in phosphate-buffered saline, the hydrogels showed a more open porous structure. We observed a degradation rate of 26–28%. Although the increase in MOL extract reduced the tensile strength of the hydrogel, the addition of GO increased the tensile strength. The PVA/MOL/GO hydrogel showed the highest antibacterial activity, with a reduction of 94% Gram-positive S. aureus and 82% Gram-negative E. coli. Finally, all samples possessed appropriate cytocompatibility with cell viability reaching 83–135% in 3T3L1 mouse fibroblast cells. This result was verified by in vitro wound-healing analysis performed by scratch assay. This study presents the potency of combined PVA, MOL, and GO as a biocompatible DFU wound dressing
