Abstract

Rising global temperatures and increasing frequency of extreme heat events have transformed thermal stress into a critical, systemic driver of cardiovascular and chronic disease burden worldwide. Despite growing recognition of heat-related health risks, substantial gaps remain regarding chronic sub-threshold exposure, morbidity outcomes, and the equity implications of adaptation strategies. This systematic review, conducted according to PRISMA 2020 guidelines, synthesizes contemporary epidemiological evidence from peer-reviewed studies published between 2020 and 2025 to characterize heat-health associations, identify vulnerability determinants, and evaluate policy implementation across diverse geographic and socioeconomic contexts. Following independent screening, quality appraisal, and data extraction, a structured narrative synthesis was performed due to significant methodological heterogeneity in exposure metrics and outcome definitions. The findings demonstrate a robust association between heat exposure and elevated risks of stroke, coronary heart disease, and accelerated progression of metabolic, respiratory, and mental health conditions, with chronic thermal stress emerging as an underrecognized contributor to long-term physiological deterioration. Vulnerability is highly stratified, disproportionately affecting older adults, women, outdoor workers, socioeconomically marginalized communities, and populations in low- and middle-income countries, particularly within urban heat island environments. Current adaptation measures exhibit limited behavioral uptake and insufficient equity-focused design. Addressing these disparities requires standardized exposure metrics, context-sensitive early warning systems, multisectoral policy integration, and targeted research on chronic thermal stress to build inclusive, climate-resilient health systems.

Abstract

Digital competency is a challenge and necessity for educators in the 21st century, especially in vocational schools. This study aims to bridge the gap by comprehensive review of digital media as a component of digital competency for teachers in Vocational Education and Training (VET). Data were collected from the Scopus, Research Gate, and Scholar databases based on inclusion and exclusion criteria. This study employs content analysis on 11 articles published in international journals indexed by Scopus between 2018 and 2024. The stages carried out include formulating material based on research questions, selecting relevant journal articles, analyzing main topics, interpreting data, identifying categories to develop digital skills, reporting findings, drawing conclusions, and suggesting further research. The findings show several technologies to develop educators' digital competence, such as blogs, websites, mobile smartphones, video conferencing, digital content and new digital devices. Project-based learning as an alternative instructional model for developing digital competencies using digital media. Digital media influences digital competence and its domain. Future studies could carry out empirical investigations based on this finding to further enhance digital competence among VET teachers.

Abstract

Many students do not demonstrate optimal mastery because EFI mate-rial is considered complex and abstract, while conventional learning using engine stands has limited accessibility outside school hours. This innovation is designed to create an immersive learning experience fo-cused on reinforcing foundational knowledge regarding the identifica-tion of components, functions, and the operational flow of the EFI sys-tem. The study employs a quantitative method with a quasi-experimental design of the Non-equivalent Control Group Design type. The research sample consisted of 80 students in the 11th grade of Light Vehicle Engineering, divided into an experimental group and a control group. Data were collected through pre-tests and post-tests, then ana-lysed using ANOVA with a significance level of α=0.05. The results of the study indicate that the use of AREFI media has a significant posi-tive impact on student learning outcomes. There was an increase in the average score from 44.73 in the pre-test to 70.92 in the post-test. The ANOVA test results showed an F value of 90.217 with a significance level of 0.000 (p < 0.05), proving that the difference in learning out-comes between the two groups was caused by the use of the AREFI media. Therefore, it can be concluded that the AREFI learning media has proven to be effective as an innovative solution for visualizing abstract EFI concepts, enhancing interaction, and facilitating deep un-derstanding among vocational high school students.

Abstract

Penelitian ini bertujuan untuk mengembangkan aplikasi Smart Repair Tracker, sebuah edukit berbasis Learning Analytics yang dirancang untuk mendukung pembelajaran mata kuliah Peralatan Otomotif di Program Studi S1 Pendidikan Teknik Otomotif. Aplikasi ini fokus pada penguatan kompetensi 6C’s (Critical Thinking, Creativity, Communication, Collaboration, Citizenship, Character) mahasiswa dalam pembelajaran otomotif. Metode yang digunakan adalah Research and Development (R&D) yang mencakup analisis kebutuhan, perancangan produk, pengembangan prototipe, uji validasi, dan uji kelayakan. Hasil uji menunjukkan bahwa 80% mahasiswa merasa aplikasi ini efektif dalam meningkatkan keterlibatan mereka dalam pembelajaran, terutama dalam simulasi berbasis Virtual Reality (VR), yang mendapatkan skor 4,9/5 dalam hal ketertarikan dan efektivitas. Selain itu, 75% mahasiswa melaporkan bahwa fitur Learning Analytics yang memberikan umpan balik langsung sangat membantu mereka untuk memahami kemajuan dan kelemahan mereka. Berdasarkan hasil uji kelayakan yang melibatkan 5 ahli, aplikasi ini memperoleh skor 4,7/5, yang menandakan bahwa aplikasi ini sangat layak digunakan dalam konteks pendidikan otomotif. Kesimpulannya, Smart Repair Tracker terbukti efektif dalam meningkatkan kualitas pembelajaran dan penguasaan keterampilan teknis serta sosial mahasiswa di bidang otomotif.

Abstract

Penelitian ini bertujuan mengembangkan dan menguji keefektifan e-book berbasis EPUB yang terintegrasi QR code untuk mendukung pembelajaran mahasiswa Program Studi Pendidikan Teknik Otomotif. E-book dirancang untuk menggabungkan fleksibilitas format EPUB yang reflowable dengan kemudahan akses video praktikum, simulasi, dan penilaian daring melalui QR code. Model pengembangan yang digunakan adalah Research and Development (RD) dengan model 4D (Define, Design, Develop, Disseminate) yang dipadukan dengan kuasi eksperimen pretest–posttest control group. Subjek penelitian adalah 62 mahasiswa yang menempuh mata kuliah praktikum AC mobil. Data dikumpulkan melalui lembar validasi ahli, angket kepraktisan, dan tes hasil belajar. Hasil validasi menunjukkan bahwa e-book berada pada kategori sangat layak dari aspek materi, media, dan bahasa. Respon mahasiswa mengindikasikan bahwa e-book sangat praktis dan membantu kemandirian belajar. Uji efektivitas memperlihatkan peningkatan hasil belajar kelompok eksperimen yang secara signifikan lebih tinggi dibanding kelompok kontrol. Integrasi QR code membuat mahasiswa lebih mudah menghubungkan konsep teoretis dengan prosedur kerja bengkel melalui akses langsung ke video, animasi, dan latihan diagnostik. Dengan demikian, e-book berbasis EPUB terintegrasi QR code layak direkomendasikan sebagai media pembelajaran digital pada pendidikan teknik otomotif.
