Abstract

Social media has become an integral part of daily life, but its intensive use also increases users’ exposure to various cybersecurity threats, making it important to understand the determinants of cybersecurity behavior. This study examines the effects of cybersecurity knowledge and social media usage intensity on cybersecurity behavior, as well as the role of cybersecurity self-efficacy as both a direct predictor and a moderating variable. A quantitative approach was employed using a survey of 115 university students who actively use social media, and the data were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS). The results indicate that cybersecurity knowledge has a positive and significant effect on cybersecurity behavior (β = 0.309, t = 3.383, p < 0.01), while cybersecurity self-efficacy emerges as the strongest predictor of cybersecurity behavior (β = 0.479, t = 4.725, p < 0.001). In contrast, social media usage intensity does not show a significant effect on cybersecurity behavior (β = 0.003, t = 0.032, p > 0.05). Furthermore, moderation analysis reveals that cybersecurity self-efficacy does not moderate the relationships between cybersecurity knowledge or social media usage intensity and cybersecurity behavior. The structural model explains 58.3% of the variance in cybersecurity behavior (R² = 0.583). These findings suggest that cybersecurity behavior among social media users is more strongly driven by cognitive and psychological factors than by usage intensity alone. Practically, effective cybersecurity interventions should prioritize strengthening users’ cybersecurity knowledge and self-efficacy rather than merely restricting social media use.Keywords— Cybersecurity behavior; Cybersecurity knowledge; Self-efficacy; Social media usage intensity; SEM-PLS

Abstract

This study aims to evaluate the performance of vertical-axis wind turbines (VAWTs) with three different configurations, including Savonius, Darrieus, and a Savonius-Darrieus hybrid wind turbine, using Computational Fluid Dynamics (CFD) simulations. The methodology involves 3D geometry modeling, simulation parameter setup, meshing, and post-simulation analysis using SolidWorks 2022 software. The simulation results indicate that the Savonius turbine achieves the highest power coefficient (Cp) and torque coefficient (Ct) among the three designs, with a maximum Cp value of 0.5 at a Tip-Speed Ratio (TSR) of 0.4. Conversely, the hybrid turbine demonstrates lower efficiency, although it theoretically offers potential for improving performance at low wind speeds. Pressure and flow velocity distributions reveal that the Savonius turbine maintains the most stable pressure pattern compared to the other configurations. These findings highlight the potential of the Savonius turbine as a small-scale renewable energy solution, particularly in urban areas with low wind speeds. Further research is recommended to optimize hybrid turbine designs using machine learning approaches and empirical validation through field experiments to support the achievement of Sustainable Development Goals (SDGs), particularly Goal 7, affordable and clean energy.

Abstract

Kegiatan pengabdian kepada masyarakat ini dilaksanakan untuk memberdayakan kelompok tani Boncah Bungo Tanjuang di Kabupaten Pasaman Barat melalui penerapan teknologi tepat guna dalam pemanfaatan limbah pelepah sawit sebagai bahan pakan ternak alternatif. Permasalahan utama yang dihadapi mitra adalah kesulitan memperoleh pakan ternak akibat keterbatasan lahan hijauan, tingginya biaya pakan komersial, dan belum optimalnya pemanfaatan limbah pertanian. Padahal, daerah ini memiliki potensi limbah pelepah sawit yang melimpah dari aktivitas perkebunan, namun selama ini belum dimanfaatkan secara maksimal. Program ini bertujuan untuk meningkatkan efisiensi penyediaan pakan ternak, mengurangi limbah pertanian, dan mendorong kemandirian ekonomi peternak melalui inovasi mesin pencacah pelepah sawit. Metode pelaksanaan meliputi analisis kebutuhan mitra, perancangan dan pembuatan mesin pencacah, uji coba dan pelatihan operasional mesin, serta pendampingan penerapan teknologi di lapangan. Hasil kegiatan menunjukkan bahwa mesin pencacah berkapasitas 200–300 kg/jam mampu menghasilkan potongan pelepah sawit berukuran 1–3 cm yang mudah dikonsumsi ternak. Penggunaan pelepah sawit sebagai pakan mampu menekan biaya pakan hingga 40%, meningkatkan ketersediaan pakan sepanjang tahun, dan mengurangi pencemaran lingkungan akibat pembakaran limbah. Kegiatan ini juga meningkatkan keterampilan peternak dalam penggunaan dan perawatan mesin, serta memperkuat sinergi antara perguruan tinggi dan masyarakat dalam penerapan teknologi tepat guna yang berkelanjutan.

Abstract

Abstract: The rapid transformation of the automotive industry towards digitalization and electric vehicles requires vocational graduates to have new competencies as well as a clear career path based on self-concept. However, students' unpreparedness in determining their specialization and the mismatch between their competencies and the needs of the EV industry make the development of a career guidance model even more important. This study aims to analyze the relevance of Super's career development theory in specialization guidance in the Automotive Engineering Vocational Program and to formulate a Self-concept-based career guidance model that is adaptive to the demands of electric vehicle technology. For this purpose, an analytical-philosophical literature review was conducted, examining 35 scientific articles and primary literature on Super's theory. The results show that the stages of career exploration, crystallization, specification, and implementation in Super's theory are in line with the process of forming EV competencies such as BMS, HV safety, electric motors, and digital diagnostics. Another important finding is that technical self-concept is formed through direct learning experiences and guided reflection, so career guidance needs to integrate self-assessment, exploration, workshops, and field experience. The study concludes that Super's theory is relevant as a foundation for vocational career guidance in the era of electrification and recommends the development of a curriculum that emphasizes career exploration and empirical research to test the effectiveness of the model.Keyword: Vocational Career; Super Theory; Electric Vehicles; Self-Concept; Career Guidance.Abstrak: Transformasi pesat industri otomotif menuju digitalisasi dan kendaraan listrik menuntut lulusan vokasi memiliki kompetensi baru sekaligus kejelasan arah karier yang berbasis Self-concept.

Abstract

Abstract: This study examines the implementation of Technical and Vocational Education and Training (TVET) in improving students’ employability in Indonesian Vocational High Schools (SMK). The analysis focuses on four operational components: institutional management, workshop organization, training approaches, and industry-based curriculum practices. The research background highlights the persistent mismatch between the expected role of SMK as producers of skilled workers and the low employment rate of their graduates. Using a qualitative case study in selected SMK, the findings reveal that improving work readiness depends not only on teaching competencies but also on the effectiveness of operational systems in these four areas. The results show that institutional governance largely shapes industrial collaboration, instructional quality, and evaluation systems aligned with labor market demands. Industry-standard workshops significantly strengthen students’ technical skills through practical activities using relevant tools and procedures. Training models such as project-based learning, teaching factory, and internships enhance practical competencies and work attitudes. Meanwhile, flexible and collaborative curricula improve the relevance of graduate skills to industry needs. Keyword: TVET, SMK, kesiapan kerja, workshop kejuruan, kurikulum industri, pelatihan vokasi Abstrak: Penelitian ini mengkaji penerapan Technical and Vocational Education and Training (TVET) dalam meningkatkan kesiapan kerja peserta didik di Sekolah Menengah Kejuruan (SMK) di Indonesia. Fokus penelitian mencakup empat aspek utama, yaitu manajemen institusi, pengelolaan workshop, metode pelatihan, dan implementasi kurikulum berbasis industri. Latar belakang penelitian didasari rendahnya serapan lulusan SMK di pasar kerja meskipun SMK ditujukan sebagai penghasil tenaga kerja terampil. Melalui studi kasus kualitatif pada beberapa SMK, ditemukan bahwa peningkatan kesiapan kerja tidak hanya ditentukan oleh kemampuan pedagogis guru, tetapi juga oleh kualitas operasional keempat aspek tersebut. Hasil penelitian menunjukkan bahwa tata kelola manajemen berperan penting dalam menjalin kemitraan industri, mengatur mutu pembelajaran, dan merancang sistem evaluasi berbasis kebutuhan pasar. Workshop berstandar industri turut meningkatkan kompetensi teknis siswa melalui praktik menggunakan peralatan dan prosedur terkini. Metode pelatihan seperti project-based learning, teaching factory, dan magang industri mendorong keterampilan praktis serta etos kerja. Kurikulum yang fleksibel dan disusun bersama industri memperkuat relevansi kompetensi lulusan. Penelitian menyimpulkan bahwa keberhasilan TVET membutuhkan sinergi kebijakan antara sekolah, industri, dan pemerintah dalam pendanaan, kurikulum, sertifikasi, dan penyediaan instruktur. Kata kunci: TVET, SMK, kesiapan kerja, workshop kejuruan, kurikulum industri, pelatihan vokasi.

Abstract

Abstract: The rapid development of digital technology has brought significant transformation to the philosophy of automotive education, particularly in its traditional learning and teaching approaches that previously relied on manual skills. This study aims to analyze the shift in automotive education from the perspective of multivariate educational philosophy, which integrates technical competencies, digital literacy, problem-solving abilities, and an understanding of electronic vehicle systems. Using a qualitative approach, data were collected through in-depth interviews and observations involving automotive teachers, workshop instructors, program coordinators, industry technicians, and students. The findings reveal that digital tools—such as vehicle scanners, simulation software, animated videos, and e-learning modules—not only enhance learning methods but also shift the learning paradigm toward more analytical and data-driven processes. The role of teachers has also evolved significantly, from mere transmitters of information to facilitators, mentors, and digital analysts. The integration of industry technology into classroom and workshop learning increases students’ job readiness and reduces the skills gap between vocational schools and professional workshops. Therefore, automotive education in the digital era requires a philosophical reconstruction to align with multivariate competence demands, curriculum relevance, and the technological needs of the modern automotive industry. Keyword: educational philosoph; automotive education; digital era; multivariate learning; industrial technology integration Abstrak: Perkembangan teknologi digital telah membawa perubahan mendasar terhadap filsafat pendidikan otomotif, terutama dalam cara belajar dan mengajar yang sebelumnya berpusat pada keterampilan manual. Penelitian ini bertujuan menganalisis transformasi konsep pendidikan otomotif dalam perspektif filsafat pendidikan multivariat, yang menekankan keterpaduan antara kompetensi teknis, literasi digital, pemecahan masalah, serta pemahaman sistem elektronik kendaraan modern. Menggunakan pendekatan kualitatif, data diperoleh melalui wawancara mendalam dan observasi pada guru otomotif, instruktur bengkel, kepala program keahlian, teknisi industri, serta siswa.
