Bone implant plates are only used temporarily during the healing process of a fractured bone. Once the healing process is complete, the implants need to be surgically removed. By using biodegradable material there will be no need for an implant removal surgery, because the implant plate will be degraded and destroyed naturally in the body. This biodegradable implant would need to bestrong enough to handle the body's weight and movement to be able to replace the bone physiologic function until the fractured bone is completely healed. A possible biodegradable material that could be degraded and destroyed naturally in the body is magnesium. However, magnesium has its limitation, its ability to resist corrosive properties is faster than a fractured bone healing process. Therefore, the plastic deformation process is done by suppressing the platewith 1%, 2%, and 3% degradation. It will increase the magnesium's ability to resist the dynamic force and improve its mechanical properties, so that the biodegradable implant plate can perform its function as a substitute for the fractured bone until the healing process is completed and degraded naturally only afterwards. The corrosive body fluid environment and recurring loads retained by the implant plate during the bone fixation process leads to fatigue of the implant plate.The crack rate testing of deformed magnesium alloys after immersion process in the physiological fluid DMEM can provide useful information on magnesium mechanical strength enhancement and subsequently whether it is feasible to be used as biodegradable bone implant plate.

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.

In the context of the global economy, the importance of international exposure for vocational students cannot be overstated. Indonesia, with its abundant educational resources and cultural richness, has yet to tap its potential as a leading destination for international students. This study examines the development and impact of a socialization program to increase Malaysian vocational students’ interest in mobility programs and further study in Indonesia. The participants in this study were university students. Data collection was conducted through an online survey using a pretest and posttest questionnaire instrument. Data were analyzed using the Wilcoxon test to test the hypothesis that there is a significant positive change in student interest and the N-Gain value to determine the magnitude of the increase in interest. The results showed a moderate increase in interest, confirming the important role of prior knowledge and institutional image in the decision-making process. These findings suggest that Indonesian universities need to increase their global visibility through strategic marketing and international collaboration. The implications of this study provide important insights for policymakers, higher education institutions, and other stakeholders in increasing Indonesia’s attractiveness as an educational destination for international students, especially from Malaysia.

Transformasi UPI menjadi PT BHMN pada awalnya didasari oleh pertimbangan bahwa kredibilitas UPI sebagai Perguruan Tinggi Negeri akan sulit dicapai ketika otonomi dan akuntabilitas belum sepenuhnya dimiliki oleh lembaga. Makna status UPI menjadi BHMN dan entrepreneur university mempunyai kesamaan visi, yaitu keduanya mengkonsepsikan suatu lembaga menuju kemandirian. Perubahan status PTN menjadi PT BHMN tidak berarti menjadikannya sebagai badan usaha yang hanya berorientasi mencari keuntungan sebesar-besarnya dan mengabaikan tujuan dan misi sosialnya. Entrepreneur university adalah universitas yang memiliki jiwa entrepreneurship (kewirausahaan) di mana aktivitas yang dilakukan berorientasi profit tanpa menghilangkan fungsinya sebagai lembaga pendidikan.

The advancement of digital technology in the Industry 4.0 era has transformed the paradigm of vocational education, necessitating that students acquire digital literacy as an essential ability. Digital literacy encompasses not just the technical proficiency in utilizing software or programs but also entails a critical understanding of ethics, data security, and professional communication skills. This study seeks to examine the impact of digital literacy on the internship performance of vocational students. The research design employs a descriptive-correlational quantitative methodology with simple linear regression analysis. Data was collected via a survey of 50 students enrolled in the Mechanical Engineering Education and Electrical Engineering Education programs at Jakarta State University, who were participating in internships in diverse manufacturing, automotive, and information technology firms. The questionnaire has undergone validation and reliability testing and is augmented by comprehensive interviews with internship supervisors to enhance the findings. The study indicates that digital literacy significantly influences internship performance, evidenced by a significance value of 0.031 (< 0.05) and an F-statistic of 4.946 (> F-table 1.624). Digital literacy has been demonstrated to improve students' technical, communicative, management, and collaborative abilities, while also augmenting their preparedness for employment in a digitized industrial landscape. This discovery affirms that digital literacy must be established as a core ability inside the vocational education curriculum. This research is unusual in its explicit emphasis on connecting digital literacy with internship performance in the industrial sector through a quantitative methodology, surpassing prior studies that predominantly concentrated on the academic context. This research underscores the necessity to enhance the curriculum, fortify business ties, and develop digital training programs to adequately educate vocational students for the challenges of the workforce.
