Abstract

Recently, the weather changes that have occurred are very unconditioned. This feels natural because it has often been felt, even though the heat that occurs is beyond its limit. This is one of the effects of global warming. Concrete is one of the most widely used materials in construction. In fact, cement production is included in the less environmentally friendly category. The purpose of this study is to find out how research on green concrete and whether it has an impact in the world of civil engineering. This research is using a quantitative method. This research describes only a few of the results of trials conducted by several researchers in the world, which prove that there is environmentally friendly concrete that can be applied and some are not. The results of this study showed that most of the innovation of green concrete is not good enough to be applied in the field. This is because in several studies it has been proven that the mixture in the manufacture of green concrete does not qualify as an aggregate material. The conclusion is that there is no innovation in the manufacture of green concrete that has worked so as not to cause damage to the earth. Therefore, other research on green concrete is very necessary to do.

Abstract

Purpose - Vocational education is highly vulnerable to disasters; however, current mitigation strategies are fragmented across spatial planning regulations, infrastructure design, and assessment technologies. This study seeks to carefully examine the evolution of Disaster Risk Reduction (DRR) research within vocational education, finding trends, knowledge frameworks, and research deficiencies, while also developing a cohesive transdisciplinary framework.Methodology - The study employs a synthesis of bibliometric analysis and Systematic Literature Review (SLR), adhering to the PRISMA 2020 guideline. The search was conducted in the Scopus database for the period 2004–2024, yielding 162 initial documents, which were further refined to 16 core papers using rigorous selection criteria. Bibliometric analysis encompasses publishing trends, keyword co-occurrence, and co-citation, utilizing bibliometrics and VOSviewer.Findings - Publications increased by 18% per year, with the Asia-Pacific region dominating (62%). Three thematic clusters were identified: adaptive infrastructure design (43.75%), spatial planning policy (31.25%), and geospatial information systems (25%). Co-citation analysis confirms that no single influential document integrates all three dimensions simultaneously within the context of vocational education.Contribution - The study formulates a transdisciplinary framework that integrates technical, spatial, and technology-based resilience within vocational education. The implications include strengthening national standards (SNI) for school buildings, integrating Geographic Information Systems (GIS) into the construction vocational school curriculum, and fostering institutional partnerships between the Ministry of Education, Culture, Research, and Technology and the National Disaster Management Authority to support region-based risk management.

Abstract

Background: The fast-paced growth of the global landscape has triggered significant transformations in various sectors, including education and the workforce. As the world enters the era of Industrial Revolution 5.0, which emphasizes sustainability and human-technology collaboration, it becomes critical for vocational high school (SMK) graduates to possess job skills that align with modern industry demands. However, a persistent skills gap remains between what vocational education delivers and what industries require. Methods: This study aims to analyse the employability level of vocational high school students in meeting industry demands during the Industrial Revolution 5.0. A quantitative approach was employed using an online survey distributed to 450 vocational students and 40 industry representatives across various sectors in Indonesia. The survey instrument focused on two main job skill dimensions: problem-solving practices and planning and organizing activities. Descriptive statistical analysis (frequency distributions, means, and standard deviations) was conducted, followed by inferential analysis using a t-test to compare students' self-assessments with industry evaluations of job readiness. Results: The findings revealed that vocational students' skills are currently at a moderate level and have not yet fully met industry expectations. A statistically significant gap was found between student perceptions and industry assessments, indicating a misalignment in readiness levels. Conclusion: These results highlight a critical employability gap that must be addressed to ensure vocational graduates are better prepared for the evolving workforce. Strengthened collaboration between vocational education institutions and industry is essential. Joint efforts should focus on establishing shared competency standards, enhancing industry-based training programs, and increasing industry participation in curriculum development to improve the alignment between education outcomes and labour market needs.

Abstract

AbstractRecent advancements in Artificial Intelligence (AI) technology have yet to fully address fundamental challenges in academic writing within the context of higher education. Most existing systems remain focused on surface-level corrections, offering limited support for students struggling to construct logical arguments, organize ideas coherently, and adhere to the structural conventions of academic discourse. This study aims to analyze and map students’ academic writing proficiency as a foundation for developing AI-based learning systems that are responsive to actual needs in higher education. Employing a descriptive quantitative approach, data were collected through a closed-ended online questionnaire distributed via Google Forms. The instrument was designed based on five key dimensions: writing structure, language proficiency, argumentation and logic, referencing, and technical skills, using a 5-point Likert scale. A total of 132 final-year students from various Indonesian universities—particularly those in construction-related disciplines—participated in the study. Contextual analysis was conducted based on study programs, and data validity was enhanced through triangulation. The findings reveal that while most students fall within the “competent” category, notable deficiencies remain in language mastery and logical argumentation, preventing many from reaching a “highly competent” level. These results highlight persistent gaps in academic literacy that necessitate innovative learning interventions. The development of AI-assisted systems capable of delivering both technical and conceptual feedback is therefore essential to improving the quality of student academic writing. Further research is recommended to design an integrated AI-based academic writing platform and to expand the study population across institutions to strengthen the generalizability of the findings. AbstrakSaat ini, kemajuan teknologi Artificial Intelligence (AI) dalam pendidikan tinggi belum sepenuhnya mampu menjawab tantangan mendasar dalam hal penulisan akademik mahasiswa. Banyak sistem yang tersedia masih berfokus pada perbaikan teknis, sementara mahasiswa kerap mengalami kesulitan dalam menyusun argumen logis, mengorganisasi ide secara koheren, dan memahami struktur wacana akademik secara utuh. Penelitian ini bertujuan untuk menganalisis dan memetakan kemampuan menulis akademik mahasiswa sebagai dasar dalam merancang sistem pembelajaran berbasis AI yang relevan dengan kebutuhan aktual di pendidikan tinggi. Metode yang digunakan adalah pendekatan kuantitatif deskriptif melalui penyebaran angket tertutup menggunakan kuesioner daring berbasis Google Form. Instrumen dirancang berdasarkan lima aspek utama: struktur penulisan, penguasaan bahasa, argumentasi dan logika, penggunaan referensi, serta keterampilan teknik, dengan skala Likert 1–5. Responden terdiri atas 132 mahasiswa tingkat akhir dari berbagai perguruan tinggi di Indonesia, khususnya dari rumpun keilmuan teknik konstruksi. Data dianalisis secara kontekstual berdasarkan program studi serta diverifikasi melalui triangulasi untuk meningkatkan validitas hasil. Temuan menunjukkan bahwa sebagian besar mahasiswa berada pada kategori “mampu” dalam menulis akademik, namun belum mencapai kategori “sangat mampu”, terutama pada aspek penguasaan bahasa dan argumentasi logis. Hasil ini mengindikasikan adanya kesenjangan dalam keterampilan literasi akademik yang memerlukan intervensi pembelajaran inovatif. Oleh karena itu, pengembangan sistem pembelajaran berbasis AI yang mampu memberikan umpan balik teknis dan konseptual secara adaptif menjadi penting untuk mendorong peningkatan kualitas penulisan ilmiah mahasiswa. Rekomendasi penelitian lanjutan mencakup pengembangan sistem AI terintegrasi dan perluasan populasi lintas institusi guna memperluas generalisasi hasil.
