Abstract

English language education in higher education increasingly emphasizes authentic and competency-based learning to prepare students for global academic and professional communication. Within this context, international visiting lectures are often positioned as part of internalization at home initiatives that provide intercultural exposure without physical mobility. This study aims to document and examine the implementation of an international visiting lecture entitled “Beyond the Classroom: English for Networking, Presentation, and Collaboration” and to explore how such an activity supports the development of English for Networking, Presentation, and Collaboration (ENPC) competencies among undergraduate English Education students at Universitas Muhammadiyah Brebes. Adopting a descriptive reflective case study design, qualitative data were collected from 47 participants through online survey responses, individual reflection logs, and selected student produced learning artifacts. The data were analyzed thematically and triangulated across sources to identify recurring patterns in participants’ experiences and perceived learning outcomes. The findings indicate that students reported increased awareness and confidence in using English for networking, presentation, and collaborative communication, alongside heightened intercultural awareness and learning motivation. Reflection narratives and learning artifacts further suggest that participants began to view English less as a classroom subject and more as a practical lingua franca for academic and professional interaction. Challenges related to varied English proficiency levels and limited opportunities for sustained collaboration were also identified. Overall, this study suggests that a well-structured international visiting lecture can serve as a pedagogically meaningful learning experience that supports competency-oriented English instruction and contributes to internationalization at home practices in non-Anglophone higher education contexts, while acknowledging the contextual and descriptive scope of the case study.

Abstract

Industrial piping systems that transport high-temperature fluids are susceptible to thermal expansion, which can cause excessive axial stress and structural failure risks. This study aims to optimize the V-Type expansion bend design to enhance material efficiency while ensuring stress levels remain within the allowable limits set by ASME B31.3. Simulations were conducted using CAESAR II software version 2014, incorporating real project data on pipe geometry, materials, and operating conditions. The results indicate that the V-Type expansion bend requires the shortest total pipe length-5452 mm-while producing a thermal stress ratio of 30%, outperforming the U-Type bends by Thermacor (6069 mm, 20.8%) and Bahaa (10000 mm, 15.8%). The V-type configuration also results in lower nozzle loads and moments, making it a safer and more cost-effective solution for field implementation.
