Abstract

Construction project delay is a condition where the execution of work does not proceed according to the agreed schedule. The construction project of Norfa Husada Mother and Child Hospital experienced delays impacting costs and operational time. This study aims to identify the factors causing delays, determine the most dominant factors, and formulate preventive measures. The method used was a questionnaire distribution to 30 respondents directly involved in the project, including contractors, consultants, and project owners. Data were analyzed using descriptive statistics (Mean Rank) with SPSS software. The results show that the Planning Factor is the most dominant cause, specifically due to design changes (redesign) and changes in the scope of work, with a mean value of 1.97. The second dominant factor is the Execution Factor, particularly regarding poor work sequence planning, with a mean value of 1.90. Based on these results, the main strategies to prevent delays include maturing the design planning before construction begins, strengthening coordination between the owner and contractor regarding scope changes, and establishing a more structured method of execution (SOP) in the field.

Abstract

Waste management is a crucial issue in sustainable development, particularly in areas with high population growth and economic activity. This study aims to evaluate the waste management system in Bangkinang Kota District, Kampar Regency, which faces various challenges, including inadequate infrastructure, low public awareness, and a suboptimal management system. The research method used is a Mixed Method approach, combining quantitative and qualitative data collection techniques simultaneously in one study. The results indicate that the waste management system in Bangkinang Kota is still not effectively integrated, particularly in operational techniques, community participation, and institutional aspects. The lack of storage facilities, unscheduled transportation, and the habit of littering are the main challenges. Recommendations from this study include improving waste infrastructure, providing ongoing community education, and strengthening regulations and coordination between relevant parties to create a sustainable and community-based waste management system.

Abstract

Purpose of the Study: This systematic review investigates the integration of digital technologies into physics education across secondary and tertiary institutions globally, identifying patterns, outcomes, and evidence-based best practices within technology-enhanced learning environments (TELEs) from 2015 to 2024. Materials and Methods: Following PRISMA 2020 guidelines, a comprehensive electronic search was conducted across six major databases—Web of Science (WoS), Scopus, ERIC, IEEE Xplore, PsycINFO, and Google Scholar—using systematically constructed Boolean search strings. Inclusion criteria comprised peer-reviewed empirical studies published in English between January 2015 and December 2024, focusing on digital technology interventions in physics education contexts. After full screening, 87 studies met the inclusion criteria and were subjected to qualitative synthesis and descriptive meta-analysis. Results: Analysis revealed five dominant technology clusters: virtual laboratories and simulations (34.5%), augmented and virtual reality environments (21.8%), adaptive learning systems and AI-assisted instruction (18.4%), gamification platforms (14.9%), and collaborative online environments (10.3%). Studies consistently reported positive effects on conceptual understanding (mean effect size d = 0.67, 95% CI [0.54, 0.80]), student engagement (d = 0.72), and laboratory skill acquisition (d = 0.58). Emerging technologies such as immersive VR and AI-driven personalization demonstrated the highest effect sizes, particularly in abstract concept visualization and formative assessment. Conclusions: Digital transformation presents substantial pedagogical opportunities for physics education, provided that implementation is theoretically grounded, teacher-mediated, and contextually tailored. Critical barriers including digital inequity, teacher preparedness, and evidence gaps in long-term retention require urgent targeted policy and research attention.
