Peran Orangtua untuk Menstimulasi Literasi Permulaan pada Anak Usia Pra Sekolah

“…Pengasuhan yang dilakukan oleh pihak ketiga lebih mengutamakan pada pemenuhan kebutuhan fisik serta keamanan bagi anak sehingga stimulasi terhadap perkembangan anak tetap menjadi tanggung jawab utama bagi kedua orangtua. Positive parenting merupakan salah satu pendekatan yang digunakan pada kegiatan pengabdian ini agar orangtua semakin menyadari peran serta tanggung jawabnya untuk mengembangkan berbagai potensi yang dimiliki oleh anak (Widowati et al, 2022) Jurnal ABDINUS : Jurnal Pengabdian Nusantara, 7 (1), 2023, 82-89 Sandy Tegariyani Putri Santoso, Tiara Juliana Jaya Latihan kecakapan hidup (exercise for practical life) serta literasi permulaan merupakan materi utama pada anak usia pra sekolah (Leplingard et al, 2003). Kedua hal tersebut dapat dipelajari anak di lingkungan rumah dengan memanfaatkan berbagai material serta aktivitas yang ada di lingkungan rumah sehari hari (Wijaya & Imran, 2021).…”

Isolation of a Flavone Apigenin and a Steroids Squalene from Peronema canescens Jack Leaves with Anti-Inflammatory Activities

“…The typical spectrum of flavonoids consists of two absorption maximums in the wavelength range of 230-295 nm (band II) and 300-560 nm (a band I). 23 Based on the results of the characterization of F1 isolate compounds, it was found that F1 isolates were characteristic of flavonoid compounds of flavone and flavonol types. Flavone compounds have a maximum absorption region of band II in the range of 250-280 nm and a maximum area of band I in the range of 310-350 nm.…”

Through-Space Charge-Transfer Thermally Activated Delayed Fluorescence Alternating Donor–Acceptor Copolymers for Nondoped Solution-Processable OLEDs

“…Thermally activated delayed fluorescent (TADF) emitters, following prompt fluorescent and phosphorescent ones, represent the third generation of electroluminescent materials for OLEDs. Fluorescent emitters can only take advantages of singlet excitons for luminescence with a maximal internal quantum efficiency (IQE) of roughly 25%, whereas phosphorescent OLEDs have the capability to reach IQE of 100% due to the presence of heavy metals that allow the harvesting of both singlet and triplet excitons for phosphorescence through significant spin–orbit coupling. − TADF materials that contain no heavy metals are capable of harvesting both triplet and singlet excitons. The usage of heavy metal complexes leads to the increase in cost and decrease in the long-term stability of devices.…”

“…The application of organic TADF materials in OLEDs has led to the great progress since the discovery of a series of carbazolyl dicyanobenzene derivatives as promising emitters. , Since then, many TADF organic emitters covering the deep-blue to red emission spectra have been synthesized and used for the fabrication of efficient OLEDs. , However, their fabrication relies on the expensive vacuum deposition technique. In this respect, TADF polymers, which are suitable for simple, low-cost, and easily scalable solution (wet) processing methods such as spin-coating, ink-jetting, etc., have attracted significant interest. − In addition, polymeric emitters are characterized by much higher morphological and thermal stability than organic TADF materials that allows devices based on them to be exploited longer.…”
