Abstract

This research aims to improve the accuracy of predicting student permit results in the digital era by utilizing machine learning techniques. The main focus is the use of a Decision Tree (DT) model optimized with a Genetic Algorithm (GA) to overcome the limitations of accuracy and testing of conventional methods. This research began with collecting student academic data, followed by preprocessing to eliminate incompleteness and organize the data format. The DT model is then built and optimized with GA, which is inspired by biological evolutionary processes to improve feature selection and parameter tuning. The results show a significant increase in prediction accuracy, from 86.19% to 87.68%, and an increase in the Area Under Curve (AUC) value from 0.755% to 0.788%. This research not only proves the effectiveness of GA integration in improving DT models, but also paves the way for the application of evolutionary techniques in educational data analysis and other fields. The main contributions of this research include the development of more accurate prediction models and practical applications in educational contexts, with the hope of assisting educational institutions in making more informed decisions for their students.

Abstract

Mifasol Learning House is a non-profit organization that works for the community with the goal of providing additional education for underprivileged children in Depok, West. The children are given a variety of training materials to help them improve their insight and knowledge so that they can compete. English language training is one of the learning materials available at this study center. This is due to the students' lack of fundamental English knowledge. Correct and accurate English vocabulary is one of the fundamentals and the main issue that students face. Based on this, lecturers in the English Language and Literature study program at Bina Sarana Informatika University participate in community service activities. This activity is packaged as training aimed at increasing English vocabulary acquisition using the Vocabulary Self-Collection Strategy (VSS). Two cycles are used in the training method. Each cycle is divided into four stages: planning, implementation, observation, and reflection. The findings of this training demonstrate that VSS can be used to improve English vocabulary acquisition. The increase in the amount of understanding understood by students in cycles I and II demonstrates the improvement in student learning outcomes. In cycle I, the average test score was 58.2. In cycle II, the average test score was 70.2. The conclusion of this activity is that the VSS strategy can be used to improve students' English vocabulary acquisition. Rumah Belajar Mifasol adalah organisasi nirlaba yang bekerja untuk masyarakat dengan tujuan membantu memberikan pendidikan tambahan bagi anak-anak kurang mampu di Depok, Barat. Di tempat ini, anak-anak tersebut mendapat berbagai materi pelatihan untuk menunjang wawasan dan pengetahuan mereka agar mampu berdaya saing. Salah satu materi pembelajaran yang diberikan pada rumah belajar ini adalah pelatihan Bahasa Inggris. Hal ini dikarenakan kurangnya pengetahuan dasar bahasa Inggris peserta didik. Kosakata bahasa Inggris yang benar dan akurat merupakan salah satu hal yang fundamental dan menjadi permasalahan utama yang dihadapi siswa. Berdasarkan hal tersebut, dosen pada program studi Bahasa Inggris dan Sastra Inggris Universitas Bina Sarana Informatika melakukan kegiatan pengabdian masyarakat. Kegiatan ini dikemas dalam bentuk pelatihan bertujuan untuk meningkatkan perolehan kosakata bahasa Inggris menggunakan Vocabulary Self-Collection Strategy (VSS). Metode pelatihan yang digunakan terdiri dari dua siklus. Tiap siklus terdiri dari empat tahap, yaitu perencanaan, pelaksanaan, pengamatan, dan refleksi. Hasil pelatihan ini menunjukan bahwa VSS dapat digunakan untuk meningkatkan perolehan kosakata Bahasa Inggris. Peningkatan hasil belajar peserta didik ditunjukkan dengan meningkatnya jumlah kosakata yang dipahami oleh peserta didik pada siklus I dan II. Nilai rata-rata hasil belajar pada siklus I adalah 58,2. Nilai rata-rata tes hasil belajar pada siklus II adalah 70,2. Kesimpulan pada kegiatan ini adalah bahwa penerapan strategi VSS dapat digunakan untuk meningkatkan perolehan kosakata bahasa Inggris peserta didik.

Abstract

This study aimed to determine the cognitive level and dimensions of knowledge about the types of Lower Order Thinking Skills (LOTS), Middle Order Thinking Skills (MOTS), and Higher Order Thinking Skills (HOTS) in class X high school physics textbooks on impulse momentum based on bloom taxonomy revision. We used a descriptive approach with a quantitative approach. The subjects of this research were three high school physics textbooks for class X from three different publishers and data collection techniques using analysis sheets. The research results on the LOTS category of the three open books do not contain this question category. In the MOTS category, the analysis results included 1) C2-Conceptual 10% book publishers, 70% C3-Procedural, 2) C2-Conceptual book publishers 23.1%, C3-Procedural 46.2%, 3) book publishers 3 C2-Conceptual 55.7%, C3-Procedural 42.9%. In the HOTS category, the analysis results included 1) 20% for publisher 1 C4-Procedural, 2) 30.7% for publisher 2 C4-Procedural, and 3) 42.9% for publisher 3 C4-Procedural. Category questions C5 and C6 are separate from the three textbooks.

Abstract

This study explores how SHRM enhances employee engagement in higher education, particularly within economics and management education. Using a qualitative library research design and thematic content analysis, the study reviewed scholarly sources published between 2014 and 2024. Literature selection followed explicit inclusion–exclusion criteria, incorporating academic works addressing SHRM, employee engagement, leadership, organizational culture, or HRM in higher education, while excluding non-scholarly publications and studies lacking methodological clarity. The findings show that SHRM strengthens engagement when aligned with institutional strategy, supported by transformational leadership, and embedded within a participatory organizational culture. Four clusters of HR practices competency-based planning, continuous professional development, performance-based rewards, and participatory performance management emerge as key drivers of engagement through their effects on motivation and organizational commitment. Based on these insights, the study proposes a conceptual model explaining how SHRM enhances cognitive, emotional, and behavioral engagement, ultimately improving teaching performance, research productivity, and institutional competitiveness. The results contribute to the limited academic literature on SHRM in higher education and offer practical guidance for universities seeking to build integrated HR strategies. Future empirical research is recommended to validate the proposed model across diverse academic contexts.
