Abstract

The presence of natural cavities in karst morphology may cause severe civil engineering and environmental management problems. Karst formations will limit the expansion of urbanization, especially infrastructure development in limestone areas. Geophysical methods, especially electrical resistivity tomography (ERT) techniques, are effective and efficient solutions to detect voids below the surface. This study aimed to develop a subsidence hazard map as basic information for infrastructure development. The identification was made by measuring electrical resistivity tomography on eight profiles in the infrastructure development plan. In addition, it was also supported by geological mapping, particularly the structural geology and types of rocks around the site. The research area consists of massive limestone, bedded limestone, and cavity limestone with generally north-south joints. The analysis of geological mapping data and electrical resistivity tomography measurements showed that the cavity limestone was identified with a north-south elongated pattern in line with the fracture pattern found on the surface at the research area. The surface lithology type, the geological structures density, and the subsurface lithology were used to develop a subsidence hazard map. This information is beneficial in determining the safe location of infrastructure development based on disaster risk mitigation.

Abstract

The purpose of this study is to reveal group data on the use of augmented reality media in teaching and learning activities so that it is easier to improve student learning outcomes. Augmented reality media was chosen based on the complexity of the scope of teaching materials consisting of thinking skills and limited practice during the implementation of distance learning. The approach for grouping the use of augmented reality media is through the K-Means algorithm with R software. The sample of this study was 136 students of Building Information and Modeling Design skills competency from 5 State Vocational High Schools spread across districts and cities, DIY Province. The review aspect used as the basis for grouping is the need for alternative media in augmented reality, ease of use, supporting facilities, and speed of understanding the material. The grouping results explain that as many as 80 students can master the material well through augmented reality media, and it is appropriate to use it during distance learning. In comparison, the remaining 56 students still find it difficult. Through the results of this grouping, it can be used to combine other media for students who still find it difficult when participating in distance learning

Abstract

This study examines the commitment of vocational teacher education students at Universitas Negeri Yogyakarta, Indonesia, and Universiti Tun Hussein Onn Malaysia (UTHM) in applying core character values. The global trend in teacher education links education and economic growth, emphasizing students' competence for the job market. However, teachers are also expected to address social and moral cohesion in the younger generation. The research involved 177 third- and fourth-year students at FPTV UTHM Malaysia and an equal number at FT-UNY, utilizing a questionnaire based on core character values. The findings indicate moderate commitment levels (58.75%) among university students. UTHM students scored slightly higher (2.42) than UNY students (2.28). The study shows that character education for vocational teacher education students in both Indonesia and Malaysia has not reached optimal levels, emphasizing the need to investigate more effective character education models for future vocational teachers.

Abstract

Artificial Intelligence (AI) is emerging as a revolutionary force that is changing how we interact and work and redefining the global education landscape, especially Vocational Education (VE). AI is an opportunity to develop learning research and good vocational Education. However, this opportunity has not been correctly utilized because not all educators can develop research and AI-based learning content well. This article reveals opportunities for current and future research development related to AI and vocational Education through bibliometric analysis. The database comes from Scopus, and 159 articles were analyzed from 2014 to 2023. Bibliometric analysis of documents, including author name, journal network, country, and keywords, is visualized using the VOSviewer program. The findings reveal three key insights: (1) research remains concentrated in vocational health, with limited exploration in other sectors such as engineering, tourism, and agriculture; (2) international collaboration is still weak, despite strong potential between countries with high and emerging publication rates; and (3) keyword clusters highlight Apprenticeship, Students, Artificial Intelligence, and Engineering Education as the main thematic areas. These insights form a roadmap for future research that emphasizes diversifying AI applications across vocational sectors, fostering cross-border collaboration, and developing innovative themes around curricula, personalized learning, and simulation-based training. Despite limitations related to database and language scope, this study offers strategic directions for advancing AI in VE research and strengthening its contributions to global vocational education development.
