Evaluation of Teachers' Role in Engineering Design Process Learning in Early Childhood
No full textCreative thinking is a crucial skill that students must acquire in order to find the most appropriate solutions to problems. This skill can be obtained through Engineering Design Process (EDP) learning which blends creativity with innovative engineering techniques by transforming new ideas into tangible forms. Research indicates that highly qualified teachers develop high-achieving students. Therefore, evaluation is needed to determine the success of learning. This research evaluates the role of teachers in EDP learning in early childhood. The data are qualitative with an evaluation approach, collected through observation and documentation techniques. To analyze the data’s validity, the researchers use Nvivo, a software program used for qualitative research. The research results show that teachers carried out their roles optimally when teaching EDP on the theme of spiders, butterflies, and ant cooperation. However, when teaching the theme of water pumps, teachers did not carry out their roles optimally. This study shows that the role of teachers has an impact on the EDP learning process. Thus, the results contribute to improving the qualifications of teachers in EDP learning to help them become more proficient educators

Mitigating Environmental Disasters Through Virtual Psychoeducation: The Urgency of Public Communication During COVID-19
No full textThe COVID-19 pandemic, which rapidly spread across Indonesia and the world, caused widespread concern and disrupted nearly all aspects of life, not just public health. In response, the Indonesian government introduced several measures, including lockdowns, physical and social distancing, and work-from-home policies. President Joko Widodo eventually pushed for the expansion and enforcement of Pembatasan Sosial Berskala Besar (PSBB) which sparked debate due to their impact on daily routines and social interaction. Social distancing challenged traditional modes of communication and socialization. Effective social interaction plays a crucial role in maintaining community well-being, particularly during crises. Yet, public communication from the government during the pandemic was often seen as inconsistent and overly optimistic, leading to confusion and reduced trust. This study highlights the urgent need for more coherent and adaptive communication strategies, especially those aligned with the digital landscape of the Industry 4.0 era
Epistemological Obstacles in the Process of Learning Mathematical Abstraction: A Systematic Literature Review
No full textThis study aims to analyze students’ mathematical abstraction abilities as epistemological obstacles in mathematics learning over the past ten years (2015 2024). A total of 65 articles were collected from the ERIC, Scopus, and Google Scholar databases, of which 27 employed a didactical design research approach. The most commonly encountered learning obstacles were epistemological (55%), followed by didactical (24%) and ontological obstacles (21%). The main difficulties experienced by students included challenges in understanding concepts, performing mathematical representations, applying procedures, and solving problems. Epistemological obstacles in the process of mathematical abstraction were identified through students’ tendencies to unconsciously reduce levels of abstraction. These reductions occurred in three interpretations of abstraction levels: the relationship between the thinker and the object of thought, the dual nature of objects and processes, and the complexity involved in understanding mathematical concepts. The findings highlight the critical need to address abstraction-related difficulties to support effective mathematics learning
Implementation of Web Technology in Occupational Health and Safety Management in the Electrical Distribution Sector
No full textThe implementation of web-based technology in occupational health and safety (OHS) management is essential for improving operational efficiency, data accuracy, and decision-making, particularly in high-risk sectors such as electrical distribution. In this study, a web-based system was developed to enhance the management of first aid kits (FAK) at PT. PLN (Persero) within the South and Central Kalimantan Distribution Unit. The manual process currently used for inspecting and maintaining FAKs is prone to human error, data loss, and delays, which can significantly impact response times in emergencies and compromise workplace safety. To address these issues, a system was designed using the waterfall development methodology and built with PHP, MySQL, and the Laravel framework. The system enables real-time data access and management, ensuring that inspections are logged accurately and efficiently. Blackbox testing was conducted to ensure the functionality and reliability of the system. The results showed that the web-based system drastically reduced manual data entry errors, improved the timeliness of FAK inspections, and provided easier access to inspection records. This solution also enhanced the overall efficiency of monitoring and reporting, allowing management to make faster, more informed decisions regarding workplace safety
