Abstract

Guru memiliki tugas profesional sesuai dengan tugas poko dan fungsinya. Membuat perencanaan pembelajaran merupakan tugas awal kemudian diakhiri dengan penilaiannya. Salah satu aspek yang harus disiapkan guru sebelum mengajar adalah mengembangkan bahan ajar. Bahan ajar termasuk salah satu aspek dalam instrumental input dari sistem pembelajaran yang memegang peran penting untuk memperlancar proses dan tujuan pembelajaran yang diinginkan. Namun, berdasarkan pengalaman di lapangan, literasi digital guru belum merata, apalagi harus menggunakan atau mengembangkan bahan ajar berbasis TIK atau bahan ajar digital, pengolahan nilai, administrasi siswa, bahkan sampai membuat multimedia interaktif. Hal ini terjadi terutama di daerah yang akses TIK nya dan kesempatan memperoleh pelatihan-pelatihan masih terbatas, seperti di luar kota. Salah satu faktor penyebabnya adalah kurangnya kesadaran dan kesempatan guru untuk dapat mengembangkan kemampuan dirinya, selain kesempatan untuk memperoleh pelatihan pada bidangnya yang juga masih terbatas. Oleh karena itu, dalam rangka turut serta meningkatkan kemampuan guru dalam pembuatan bahan ajar digital, kami mengajukan kegiatan ini. Tujuan dari kegiatan ini adalah diharapkan guru-guru mampu mengembangkan bahan ajar digital, mengintegrasikan tekmologi dalam pembelajaran dan dapat memanfaatkan teknologi untuk kepentingan akademik dan administrasi di sekolah. Metode yang digunakan dalam kegiatan ini adalah pelatihan, praktek pembuatan media, diskusi dan proyek. Luaran kegiatan ini adalah guru dapat menghasilkan bahan ajar digital dan mengintegrasikan tekmologi dalam pembelajaran, dan  dapat memanfaatkan teknologi untuk kepentingan akademik dan administrasi.

Abstract

The climate change caused by the widespread and continuous use of fossil fuels is a problem that needs to be addressed urgently. One of the solutions offered is through an energy transition towards the use of new or renewable and low-carbon fuels. Hydrogen gas as a carrier of energy is an alternative solution that has attracted the attention of researchers, due to its high combustion energy and environmental friendliness. The production of hydrogen gas using the Proton Exchange Membrane Water Electrolysis (PEMWE) method is considered effective for large-scale production. This study investigates the impact of catalyst loading and various current densities on hydrogen production in the PEM water electrolysis process, utilizing the Cu2O/C catalyst. This study investigates the impact of catalyst loading and different current densities on hydrogen production in the PEM water electrolysis process, utilizing the Cu2O/C catalyst. The electrode catalytic properties were evaluated using the Cyclic Voltammetry (CV) method to determine the Electrochemical Surface Area (ECSA) and the Electrochemical Impedance Spectroscopy (EIS) method to determine the electrical conductivity. The ECSA and EIS measurements demonstrated that the best results were obtained at a higher catalyst loading of 2 mg/cm2 with an ECSA value of 0.21 m2/g and electrical conductivity of 3.04 × 10−6 S/cm. The production of hydrogen results showed that the highest hydrogen production rate was 3.75 mL/s with a catalyst loading of 2.5 mg/cm2, indicating that increasing the load could lead to a higher rate of hydrogen gas production, but this is highly dependent on the surface area utilized. Additionally, at higher current densities, the cell resistance in the electrolysis process may decrease, leading to reduced electrode efficiency for hydrogen production. Thus, the use of high currents may not always be advantageous in hydrogen production using the PEM water electrolysis method.

Abstract

Penjaminan mutu dalam pendidikan teknik dan kejuruan (PTK) menjadi perhatian, sebagai akibat perubahan tatanan pendidikan dan permintaan lulusan yang terampil dan siap kerja. Penelitian ini menyajikan analisis bibliometrik komprehensif penelitian penjaminan mutu PTK dari tahun 2003 hingga 2022. Data divisualisasikan menggunakan VOSviewer dan Tableau. Penelitian ini bertujuan untuk memberikan wawasan tentang distribusi kuantitatif, pola kutipan, penyebaran geografis, dan topik-topik yang muncul di bidang ini. Hasil studi menunjukkan peningkatan volume publikasi mengenai penjaminan mutu di PTK. Pola pengutipan menunjukkan bahwa kedalaman eksplorasi dan keterlibatan dengan pengetahuan yang ada tidak kuat secara proporsional. Federasi Rusia muncul sebagai kontributor utama dalam hal keluaran dokumen. Kurangnya kolaborasi penelitian internasional antar negara, menandakan perlunya peningkatan keterlibatan global. Tren yang teridentifikasi dalam penelitian dapat dikategorikan menjadi tiga kelompok. Klaster 1 berfokus pada aspek-aspek yang berkaitan dengan penerapan penjaminan mutu di PTK, Klaster 2 mendalami pendekatan metodologis dalam konteks ini, dan Klaster 3 mengeksplorasi konteks penelitian terkait dengan nilai, manfaat, atau tujuan penerapan penjaminan mutu di PTK. Artikel ini juga menyajikan refleksi atas temuan sebagai penelitian yang memerlukan eksplorasi lebih lanjut. Artikel ini dapat bermanfaat bagi para peneliti empiris yang ingin mengkaji evolusi tema penelitian yang berkaitan dengan penjaminan mutu dalam pendidikan kejuruan.

Abstract

This study aims to design and evaluate an Augmented Reality (AR) application for workshop tool recognition, with a focus on enhancing interactivity and student engagement in technical education. Developed using the ADDIE methodology—Analysis, Design, Development, Implementation, and Evaluation—the application integrates Blender for 3D modelling, Unity for development, and Vuforia for AR tracking. Usability was assessed through the System Usability Scale (SUS), involving 48 students from workshop practicum and Occupational Health and Safety (OHS) courses. The application achieved a SUS score of 50.5, classified as Fair according to the classification by Bangor et al. (2009). Key usability aspects were rated positively, including comfort (4.2), ease of use (4.0), functional integration (3.9), stability (4.1), and ease of learning (4.3). While the study highlights the application's potential as an effective learning tool, limitations include a small, institution-specific sample size. Future research should examine its adaptability in broader educational contexts and assess its impact on student learning outcomes. This study supports the integration of AR in technical education, fostering more interactive, efficient, and Industry 4.0-aligned learning environments.
