Abstrak Ekspresi wajah merupakan bentuk komunikasi non-verbal yang penting dalam memahami kondisi emosional peserta didik di ruang kelas. Pemahaman ini dapat membantu pendidik menyesuaikan metode pengajaran sesuai dengan keadaan emosional siswa, sehingga proses belajar mengajar menjadi lebih efektif. Penelitian ini bertujuan untuk mengembangkan dan menerapkan sistem pengenalan ekspresi wajah secara real-time di ruang kelas dengan memanfaatkan arsitektur Vision Transformer (ViT). Dua pendekatan sistem dikembangkan dalam penelitian ini: sistem dual-stage yang memanfaatkan kombinasi model deteksi wajah YOLOv11s dan model pengenalan ekspresi wajah HybridViT (ResNet-50), serta sistem single-stage yang menggunakan model YOLOv11s untuk langsung mendeteksi emosi dari citra wajah. Dataset yang digunakan meliputi Real-world Affective Face Database (RAF-DB), Face Detection Dataset, dan Facial Expression in Classroom, yang masing-masing digunakan untuk pelatihan awal dan fine-tuning model. Hasil pengujian menunjukkan bahwa sistem dual-stage memiliki performa klasifikasi yang lebih baik dengan nilai mean Average Precision (mAP) sebesar 0,2846, dibandingkan sistem single-stage dengan mAP sebesar 0,1603. Sebaliknya, dari segi efisiensi inferensi, sistem single-stage lebih unggul dengan latensi rata-rata per wajah sebesar 0,290 ms (6.539 FPS) di GPU dan 1,862 ms (545 FPS) di CPU, dibandingkan sistem dual-stage yang memiliki latensi lebih tinggi. Selain itu, evaluasi menunjukkan ketidakseimbangan performa antar kelas emosi akibat distribusi data yang tidak merata. Secara keseluruhan, kedua pendekatan menunjukkan potensi yang menjanjikan untuk implementasi sistem pengenalan ekspresi wajah di ruang kelas. Keduanya masih dapat ditingkatkan dari segi akurasi, generalisasi antar emosi, serta efisiensi waktu inferensi melalui peningkatan kualitas dataset dan eksplorasi teknik pelatihan lanjutan. Kata Kunci: Pengenalan Ekspresi Wajah, Vision Transformer, YOLOv11s, Real-Time, Ruang Kelas, Dual-Stage, Single-Stage Abstract Facial expressions serve as an essential form of non-verbal communication in understanding students' emotional states in the classroom. This understanding enables educators to adjust their teaching methods according to students' emotions, thus improving the effectiveness of the learning process. This study aims to develop and implement a real-time facial expression recognition system in classroom settings by utilizing the Vision Transformer (ViT) architecture. Two system approaches were developed: a dual-stage system combining a YOLOv11s face detection model with a HybridViT (ResNet-50) facial expression recognition model, and a single-stage system using a YOLOv11s model to directly detect emotions from facial images. The datasets used include the Real-world Affective Faces Database (RAF-DB) and the Facial Expression in Classroom Dataset, which were employed for model training and fine-tuning, respectively. Evaluation results demonstrate that the dual-stage system achieves superior classification performance with a mean Average Precision (mAP) of 0.2846, compared to the single-stage system's mAP of 0.1603. However, in terms of inference efficiency, the single-stage system outperforms the dual-stage system, achieving a lower average latency per face of 0.290 ms (6.539 FPS) on GPU and 1.862 ms (545 FPS) on CPU. The evaluation also highlights an imbalance in classification performance across emotion classes, primarily due to the uneven distribution of training and fine-tuning data. Overall, both approaches exhibit promising potential for facial expression recognition applications in classroom environments. Further improvements in accuracy, emotional generalization, and computational efficiency can be achieved through enhanced dataset quality, balanced emotion representation, and exploration of advanced training techniques.

The ADKAR change management model was applied to enhance Learning Management System (LMS) adoption at higher education. This study highlights distinct differences between LMS users and non-users across all five stages of the ADKAR model Awareness, Desire, Knowledge, Ability, and Reinforcement. LMS users exhibited a higher level of Awareness, recognizing the rationale for LMS adoption and its benefits, while non-users showed limited understanding and engagement. In terms of Desire, LMS users demonstrated stronger motivation and a sense of urgency to adopt LMS, compared to non-users who lacked initiative and internal drive. Knowledge gaps were evident, with LMS users possessing better technical skills and problem-solving abilities, whereas non-users required more training and access to resources. Similarly, LMS users demonstrated higher Ability, effectively applying knowledge in practice, whereas non-users struggled due to insufficient practical experience and mentorship. Lastly, in the Reinforcement stage, LMS users benefited from ongoing recognition and support, while non-users lacked sufficient reinforcement mechanisms. The study concludes that targeted interventions, such as personalized training, mentorship, and effective communication, are essential to bridge these gaps and ensure broader LMS adoption across the institution.

The rapid development of digital financial services has driven the high adoption rate of financial applications in Indonesia. However, the increase in use is not always accompanied by an adequate level of financial literacy, raising questions about the main determinants of digital financial system usage behavior. This study aims to test the expanded technology acceptance model by integrating the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) and information system success model, as well as evaluating the role of user satisfaction and financial literacy in driving the actual use of digital financial services. This study uses a quantitative approach with a cross-sectional design. Data was collected through a survey of active users of digital financial services in Indonesia and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The research model examines the influence of UTAUT2 constructs on behavioral intention, the continued relationship between behavioral intention, user satisfaction, and system use, and the role of financial literacy moderation in the relationship between intention and system use. The results of the analysis show that behavioral intention has a significant effect on user satisfaction and system use. Furthermore, user satisfaction has proven to be the most powerful determinant of the actual use of the system, beyond the direct influence of behavioral intention. In contrast, financial literacy has not been shown to moderate the relationship between behavioral intention and system use, suggesting that ease of use and user experience have a more dominant role than formal financial literacy levels in the context of modern digital financial services. The research model has a high ability to explain the variation in user satisfaction and system usage. This research contributes to the development of the technology adoption literature by integrating pre-adoption and post-adoption perspectives in one comprehensive conceptual framework. In practical terms, these findings emphasize the importance of improving the quality of experience and user satisfaction as the main strategy to encourage the sustainability of the use of digital financial services in Indonesia.

The Sundanese Kacapi Siter exhibits distinctive microtonal characteristics and acoustic phenomena requiring objective documentation. This study integrates high-fidelity audio recording with Fast Fourier Transform (FFT) analysis to examine the microtonal properties of the Pelog Sunda tuning system and the missing fundamental phenomenon in this traditional instrument. Using Practice-Led Research methodology, we recorded 20 single-note samples with a Neumann TLM 103 condenser microphone in natural reflective classroom conditions, analyzing them through SPAN FFT spectral analysis and cent deviation calculations against 12-TET standards. Results demonstrate systematic microtonality with deviations ranging from -15 to +28 cents, with note "Ti" consistently sharp (+17 to +28 cents) and note "Na" consistently flat (-5 to -13 cents) across octaves (p<0.001, effect size d=2.4). Spectral analysis reveals a missing fundamental phenomenon in low-register notes (La 4: 58.2 Hz, Ti 4: 66.5 Hz), where harmonics dominate perceived pitch despite weak fundamental-frequency energy (-14.3 to -8.9 dBFS fundamental vs. -6.2 to -4.1 dBFS second harmonic). These findings provide quantitative evidence that Sundanese tuning represents a structured non-Western pitch system with intentional microtonal design, advancing computational ethnomusicology through objective acoustic documentation methods that enable preservation, comparative analysis, and technological applications in digital instrument development.
