Abstract

Study towards the recycling of PET waste has arisen in the last decades. One of the most widely used methods was the mechanical recycling process due to its simplicity and low cost of production. In this research, PET waste obtained from the disposable water gallon containers was used to produce recycled PET fibers for textile applications. The PET fibers were prepared using the extrusion technique by varying the processing temperatures, i.e., 200, 210, 220, 230, and 240°C. The diameter, FTIR analysis, XRD analysis, and mechanical properties of the PET fibers at various processing temperatures were studied. The results showed that the optimum processing temperature for preparing recycled PET fibers was 210°C with a diameter of 0.23 mm, a degree of crystallinity of 8.9%, a tensile strength of 70.4 MPa, and an elongation at break of 83.6%. In conclusion, PET waste shows a promising application to be processed as recycled PET fibers for textile applications.

Abstract

The engaging and personalized nature from short video makes it quickly popular, yet concerns persist about their potential to diminish critical thinking skills. This study investigates whether short videos with educational content can improve students' critical thinking skills. Using a quasi-experiment method, Thirty-three participants were divided into control and experimental groups, with critical thinking measured using the Holistic Critical Thinking Scoring Rubric (HCTSR) based on essay analysis in pretest and posttest. After administering educational short videos to the experimental group, the results showed that there was an increase in students' critical thinking skills, shown by the result of controlling the pretest variable through the ANCOVA test with a p-value of <0.001. The result highlights the potential of educational short videos as tools for fostering critical thinking by providing interventions which prioritize treatment fidelity through standardized protocols (SOPs) for content delivery, validating assessment tools, and structuring content design. Recommendations for future research include larger sample sizes, repeated data collection at strategic intervals, and rigorous validation of question complexity.

Abstract

Abstract: Technical and Vocational Education and Training (TVET) plays a crucial role in bridging the needs of the industrial world with the goals of sustainable human development. Within the context of the Sustainable Development Goals (SDGs), particularly Goal 4.7 on Education for Sustainable Development, this study revisits the philosophy of TVET through three dimensions: realism, heart, and logic. The research aims to uncover the philosophical foundations of TVET within the SDG framework by tracing classical German thought (Kerschensteiner, Spranger, Fischer) alongside modern paradigms rooted in technology, vocational psychology, and educational sustainability. The method employed is an integrative bibliometric-based literature analysis of 1,041 Scopus-indexed articles (20152024), combined with a philosophical review of five major sources from Germany, the United Kingdom, China, and Indonesia. The findings reveal four key insights: (1) Educational realism emphasizes contextual and meaningful work competencies; (2) The dimension of heart highlights moral values, humanity, and psychological well-being within the TVET system; (3) Educational logic is reflected in technology-based curricula that integrate knowledge, skills, and values; and (4) The integration of SDGs fosters ecological awareness and social responsibility. TVET is thus conceptualized as a philosophical system that unites work reality, humanity, and scientific rationality toward a sustainable vocational curriculum for the 21st century.Keyword: Philosophy of TVET; SDGs; vocational ethics; vocational psychology; educational sustainabilityAbstrak: Pendidikan Teknik dan Kejuruan (TVET) berperan penting dalam menjembatani kebutuhan dunia industri dengan tujuan pembangunan manusia berkelanjutan.

Abstract

This community service program is motivated by the fact that the people of Jorong Pinang Gadang still face various obstacles in managing agricultural products, especially in the post-harvest stage. The limitations of the tools and technology used are still the main obstacles in increasing agricultural efficiency and productivity. From an economic perspective, the income of the community largely depends on agricultural products, especially from the sale of grain. However, due to the limitations of post-harvest technology, the results obtained often experience shrinkage due to loss of grain in the threshing process. In addition, the selling price of grain which tends to fluctuate makes it difficult for farmers to obtain stable profits. This service aims to increase the efficiency of the rice threshing process and stimulate interest in rice farming among farmers, especially in Jorong Pinang Gadang, Nagari Koto Padang, Kabupaten Dharmasraya. The stages of the activity include: (1) stages starting from field surveys, (2) identifying problems, (3) determining solutions, (4) making designs, (5) making tools, (6) testing tools, (7) demonstrations, (8) handover of tools and, (9) evaluation and monitoring. This training successfully improved post-harvest efficiency for farmers and achieved local food security for the community in Nagari Koto Padang. The innovative rice thresher technology has increased farmers' productivity, both in terms of harvest quality and economics. Furthermore, the community has gained a better understanding of how to effectively manage a farmer group to achieve shared goals. Keywords: Training, innovation in rice thresher technology, post harvest efficiency, food security

Abstract

Virtual Reality (VR) has become an option to be used as a learning medium in engineering. A study of the effectiveness of VR is needed to determine which fields and types of learning are suitable to employ it. This work aims to reveal the effectiveness of virtual reality media on students' cognitive and practice skills. The role of the media as a tool to make learning more efficient and effective. VR media brings learning in the virtual world that seems to be done in real terms. The research method used was a quasi-experiment with a posttest-only control group design research approach. The research subject consisted of two homogeneous classes. Learning outcomes are evaluated by testing students' cognitive and practice skills. The novelty of this research is the creation of learning media that are identical to the welding process simulator. Visual practice places and equipment in virtual form through VR are made to resemble practice places and equipment used in real situations. This similarity aims to provide concrete information about the welding process. The study revealed that the use of VR media significantly affected their knowledge. However, it did not significantly affect their practice skills. VR has not been able to provide an experience closer to real-life conditions during welding, such as heat, sparks, and sounds that appear when the electrode touches the workpiece. The distance between the electrode and the workpiece significantly affects the welding result in the welding process.

Abstract

Social media has become an integral part of daily life, but its intensive use also increases users’ exposure to various cybersecurity threats, making it important to understand the determinants of cybersecurity behavior. This study examines the effects of cybersecurity knowledge and social media usage intensity on cybersecurity behavior, as well as the role of cybersecurity self-efficacy as both a direct predictor and a moderating variable. A quantitative approach was employed using a survey of 115 university students who actively use social media, and the data were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS). The results indicate that cybersecurity knowledge has a positive and significant effect on cybersecurity behavior (β = 0.309, t = 3.383, p < 0.01), while cybersecurity self-efficacy emerges as the strongest predictor of cybersecurity behavior (β = 0.479, t = 4.725, p < 0.001). In contrast, social media usage intensity does not show a significant effect on cybersecurity behavior (β = 0.003, t = 0.032, p > 0.05). Furthermore, moderation analysis reveals that cybersecurity self-efficacy does not moderate the relationships between cybersecurity knowledge or social media usage intensity and cybersecurity behavior. The structural model explains 58.3% of the variance in cybersecurity behavior (R² = 0.583). These findings suggest that cybersecurity behavior among social media users is more strongly driven by cognitive and psychological factors than by usage intensity alone. Practically, effective cybersecurity interventions should prioritize strengthening users’ cybersecurity knowledge and self-efficacy rather than merely restricting social media use.Keywords— Cybersecurity behavior; Cybersecurity knowledge; Self-efficacy; Social media usage intensity; SEM-PLS
