ABSTRACT. Dye-sensitized solar cells (DSSCs) offer a promising sustainable solution to global electricity challenges by converting sunlight into electricity using photosensitive dyes. This study explores the performance of DSSCs using natural dyes from sappanwood (Caesalpinia sappan L.), pandan leaves (Dracaena angustifolia), and telang flowers (Clitoria ternatea L.). Extraction of the dyes was done through maceration, with combinations made in single, double, and triple-component blends. UV-Vis spectroscopy showed increased light absorption in the 400-700 nm range. Combination F5 uniquely showed absorption peaks at 534.22, 573.64, 619.12, and 664.21 nm, which were affected by nine conjugated double bonds and electron transfer from C=C and carbonyl groups. Comparative band gap energy analysis showed that the triple-blending dyes exhibited the lowest energy range of 0.3392-0.4469 eV, compared to the double dye (0.4549-0.5778 eV) and single dye (0.4541-0.6248 eV), indicating better light harvesting ability. FTIR analysis confirmed the chemical structure of the dye. Prominent spectroscopic features include a broad band of 3332 cm-1 for hydroxyl groups, peaks at 2919 cm-1 and 1732 cm-1 representing alkane and carboxyl groups in cellulose, and an aromatic lignin C=C stretch at 1672 cm-1. The optimized F5 blend (1:2:1 ratio) achieved the highest solar cell efficiency of 3.24% with a band gap of 0.3392 eV. These results validate the potential of natural dye blends as DSSC sensitizers, showing enhanced absorption spectrum, improved stability, and increased electric current generation. Keywords: Dye-sensitized solar cells, Triple-component blending, Caesalpinia sappan L., Dracaena angustifolia, Clitoria ternatea L.

This study aims to obtain information about: (1) differences in learning outcomes between students who study using the ARIAS learning model and students who learn using direct learning (DL); (2) differences in learning outcomes between students who have high creativity and students who have low creativity; and (3) whether the relationship between the use of learning models and learning outcomes in continental food processing is influenced by students' creativity. This experimental study was conducted using a 2 x 2 factorial design, with the moderator variable being students' creativity. In the experiment, the separation of the level of student creativity was not carried out significantly. Students are called to have high creativity, if they have a score higher or equal to the median group (ian median), while students are called to have low creativity, if they have a score less than or below the median (<median) group. The study was conducted in class XI Hospitality 1 by applying the ARIAS learning model, and class XI Hospitality 2 by applying DL. The study found that: (1) students who studied using the ARIAS learning model obtained significantly higher cognitive, affective and psychomotor learning outcomes than students who studied using DL; (2) students who have high creativity, obtain significantly higher cognitive, affective and psychomotor learning outcomes than students who have low creativity; and (3) the relationship between the use of learning models and learning outcomes in continental food processing is influenced by student creativity.

Penerapan model pembelajaran tatap muka merupakan model pembelajaran yang paling mudah dilakukan oleh guru. Tetapi, guru juga harus lebih kreatif mengkolaborasikan model pembelajaran tatap muka dengan model pembelajaran yang lain, misalnya dikolaborasikan dengan model pembelajaran berbasis online atau pembelajaran elektronik (e-learning). Penerapan e-learning berbasis web ini dapat menjadi lebih interaktif dalam pembelajaran. Pada sistem e-learning ini tidak memiliki batasan akses, kegiatan belajar mengajar dapat dilakukan lebih banyak waktu. Keluasan dari segi waktu ini memberikan kesempatan kepada siswa untuk memilih waktu belajar sendiri, sehingga siswa mempunyai waktu yang cukup untuk mengembangkan pengetahuan dan pemikirannya. Tujuan dari artikel ini yaitu mengkaji penerapan Hybrid Learning sebagai alternatif model pembelajaran elektronika dasar di SMK Al Azhar Azzayyadiyah. Metode Penelitian dari artikel ini adalah studi literatur dengan cara mempelajari dan menelaah jurnal yang berkaitan. Pembelajaran Hybrid Learning bisa dijadikan sebagai alternatif model pembelajaran elektronika dasar di SMK Al Azhar Azzayyadiyah.
