Abstract

In the current asynchronous teaching at Horizon University Indonesia, students are still using several English learning applications and media, such as Duolingo, ELSA, and others. These tools are employed as a means of remote learning specifically aimed at supporting the Global Workplace English Program (GWEP) at Horizon University. The purpose of using these media is to help Horizon students improve their English test scores (EFSET) as part of their preparation for entering the workforce, as well as to enhance their four English language skills. Based on this, we are conducting a study to determine which application is most suitable and can encourage students at Horizon-U to be more active, and motivated, and ultimately improve their vocabulary in English. Vocabulary is one of the language aspects which should be learned. Learning vocabulary is important because people can speak, write, read and listen. Moreover, people have to know the vocabulary first. It means that in learning vocabulary, people need to know and understand the meaning of vocabulary and how to use vocabulary in the right context. In this research, the researcher used qualitative methods, including questionnaires and interviews, to gather information on students’ perceptions. This study was conducted in two classes at Horizon-U, with 50 participants from GWEP 4 providing positive feedback about the Duolingo and ELSA applications. Therefore, the researcher aims to explore the students’ perceptions of using Duolingo and ELSA, focusing on the topic “A Comparative Study of Student Perceptions on Vocabulary Learning Using Duolingo and ELSA.”

Abstract

Emosi penonton konser merupakan aspek psikologis penting yang memengaruhi kualitas pengalaman hiburan, keterlibatan audiens, dan kepuasan individu dalam menikmati pertunjukan musik secara langsung. Namun, dinamika emosi penonton cenderung berubah secara cepat dipengaruhi oleh suasana acara, performa musisi, interaksi sosial, dan pengalaman personal selama konser berlangsung. Penelitian ini bertujuan mengembangkan model deep learning multimodal untuk menganalisis emosi penonton konser menggunakan data visual dan perilaku audiens. Pendekatan yang diusulkan mengintegrasikan data ekspresi wajah, perilaku penonton, dan interaksi digital untuk meningkatkan akurasi analisis emosi. Arsitektur hybrid Convolutional Neural Network (CNN) dan Bidirectional Long Short-Term Memory (BiLSTM) digunakan untuk menangkap pola spasial dan temporal dari data multimodal. Model dirancang untuk melakukan analisis emosi secara real-time serta mengidentifikasi perubahan emosional pada lingkungan dinamis seperti konser musik langsung, festival, dan pertunjukan hiburan digital. Metode penelitian meliputi pengumpulan data menggunakan sensor kamera, pra-pemrosesan data, pengembangan model, dan evaluasi performa menggunakan metrik accuracy, precision, recall, F1-score, dan RMSE. Hasil akhir penelitian berupa model deep learning multimodal yang mampu menganalisis emosi penonton konser secara lebih adaptif dibandingkan pendekatan unimodal.

Abstract

Speaking is widely considered one of the most challenging skills for both university and high school learners, not primarily due to limited grammar or vocabulary, but because of psychological barriers such as fear of making mistakes and low self-confidence. This community service program, entitled “No Grammar, No Cry: Encouraging Confident English Communication,” aims to address these challenges by shifting learners’ focus from grammatical perfection to meaningful communication. The program was implemented through interactive workshops, peer conversation sessions, confidence-building games, real-life communication simulations, and mentoring activities to create a supportive and low-anxiety learning environment. A qualitative approach was employed to explore participants’ experiences, perceptions, and mindset changes during the program. Data were collected through participant reflections, observational notes, and informal discussions. The findings reveal that participants demonstrated increased willingness to speak, reduced speaking anxiety, and improved fluency and confidence in expressing ideas. In addition, learners developed a more positive attitude toward making mistakes, recognizing them as part of the learning process. Overall, the program highlights the importance of collaborative learning and experiential practice in fostering communicative competence. It also contributes to bridging the gap between theoretical knowledge and real-life communication, while promoting learner autonomy, sustained motivation, and adaptive communication skills.

Abstract

Perkembangan teknologi digital membawa perubahan besar dalam dunia pendidikan, khususnya dengan meningkatnya penggunaan media sosial di kalangan mahasiswa. Media sosial memberikan kemudahan dalam berkomunikasi dan memperoleh informasi, namun penggunaan yang berlebihan dapat menimbulkan dampak negatif terhadap proses belajar. Salah satu dampak yang sering muncul adalah menurunnya konsentrasi mahasiswa saat mengikuti pembelajaran berbasis aplikasi. Penelitian ini bertujuan untuk mengetahui hubungan antara waktu penggunaan media sosial dengan penurunan konsentrasi mahasiswa saat menggunakan aplikasi pembelajaran. Penelitian ini menggunakan metode kuantitatif dengan pendekatan korelasional. Subjek penelitian adalah 67 mahasiswa Horizon University Indonesia dari tiga Fakultas. Data dikumpulkan menggunakan angket dengan skala Likert dan dianalisis menggunakan korelasi Pearson. Hasil penelitian menunjukkan adanya hubungan yang signifikan antara waktu penggunaan media sosial dengan penurunan konsentrasi belajar. Semakin lama waktu penggunaan media sosial, semakin rendah tingkat konsentrasi mahasiswa saat menggunakan aplikasi pembelajaran.

Abstract

Learning effectiveness in higher education continues to be a significant concern, particularly in learning environments that still rely heavily on lecture-based instruction. Although such approaches allow for efficient content delivery, they often limit student engagement and reduce opportunities for meaningful learning. This study aims to explore how active learning approaches can enhance learning effectiveness from the perspective of university students.A qualitative research design was employed to capture students’ experiences and perceptions of active learning. The study involved university students who participated in learning activities such as group discussions, collaborative tasks, problem-solving exercises, and reflective practices. Data were collected through classroom observations, reflective writings, and semi-structured interviews. The findings indicate that active learning fosters higher levels of engagement, encourages participation, and promotes deeper understanding of learning materials. Students also reported increased confidence in expressing ideas and a greater sense of responsibility toward their learning. In addition, active learning was found to support the development of critical thinking and the ability to connect theoretical concepts with real-life situations.Overall, this study highlights that active learning contributes to more effective and meaningful learning experiences by creating interactive, student-centered environments. It suggests that integrating active learning into higher education can support sustained engagement and improved learning outcomes

Abstract

The increasing deployment of intelligent systems across healthcare, industrial automation, smart cities, transportation, and edge-computing environments has intensified concerns regarding privacy, data sovereignty, and secure collaborative learning. This study evaluates the effectiveness of Federated Learning (FL) as a privacy-preserving paradigm capable of supporting distributed intelligence without requiring centralized data collection. An empirical experimental design was implemented using a federated architecture consisting of decentralized client nodes, a central aggregation server, the Federated Averaging algorithm, and integrated secure aggregation with differential privacy mechanisms. Experimental evaluation was conducted through repeated validation under heterogeneous client configurations and varying data distributions. The results demonstrate that the proposed framework achieved strong predictive performance, attaining 93.41% accuracy and 95.28% AUC-ROC while maintaining stable convergence under non-identically distributed data conditions. Security evaluation revealed substantial reductions in model inversion, membership inference, and gradient leakage attacks, confirming the effectiveness of the implemented privacy-preserving mechanisms. Scalability analysis further indicated that the framework maintained reliable performance across expanding client populations with acceptable communication overhead and computational efficiency. The findings confirm that Federated Learning provides a practical and scalable foundation for trustworthy intelligent systems by balancing predictive effectiveness, privacy protection, security resilience, and operational feasibility in distributed environments.

Abstract

This study investigates university students’ perceptions of ChatGPT as a speaking partner in English-speaking practice. Employing a qualitative research design, the study involved English major students at Horizon University Indonesia who engaged in ChatGPT-assisted speaking activities for four weeks. Data were collected through semi-structured interviews and reflective journals and analyzed using thematic analysis to examine students’ perceptions, perceived benefits and challenges, and the impact of ChatGPT on their motivation and speaking confidence. The findings reveal that students generally perceived ChatGPT as a helpful, accessible, and non-judgmental speaking partner. Its use provided increased opportunities for speaking practice, facilitated vocabulary development, and offered immediate feedback, which contributed positively to students’ motivation and confidence. Nevertheless, challenges were identified, including limited emotional interaction, occasional unnatural responses, and difficulties in sustaining extended contextual conversations. Overall, the study concludes that ChatGPT can function as an effective supplementary tool in English-speaking practice, particularly when integrated with appropriate pedagogical guidance to support EFL learners’ oral communication in higher education.
