There is a lack of awareness and knowledge among the Malaysian construction industry about waste management reduction. Numerous nations worldwide have understood and have incorporated the concept of the 3R (reduce, reuse, and recycle) in waste management, and it has worked out well. This study investigated construction waste issues and developed a model for sustainable reduction by applying 3R using a partial least squares structural equation modeling PLS-SEM in Malaysia. The research methodology adopted the quantitative and qualitative approaches by sending a survey questionnaire to the relevant stakeholders to obtain their views or perceptions and interviewing an expert in the related field about waste reduction in the Malaysian construction industry. Three hundred thirty questionnaires were collected within six months of submission. The significant factors are determined using mean ranking for the reduce, reuse and recycle elements. Based on the results, the exploratory power of the study model is considered sustainable with R² values of 0.83%. At the same time, the results of relationships between improving factors, policy-related factors, construction waste generated, and sustainable construction waste reduction were significant. Also, the findings revealed that the top factors for waste generation on reducing, reusing, and recycling are lack of design and documentation, and lack of guidance for effective construction waste-collecting. The paper will explore different and dynamic practices, such as recycling, reuse of construction waste management cost reduction, enabling stakeholders and managers to estimate and quantify the actual size of CWM costs and benefits for sustainable development goals.

Driving fatigue is a serious issue for the transportation sector, decreasing the driver’s performance and increasing accident risk. This study aims to investigate how fatigue mediates the relationship between the nature of work factors and driving performance. The approach included a review of the previous studies to select the dimensional items for the data collection instrument. A pilot test to identify potential modification to the questionnaire was conducted, then structural equation modelling (SEM) was performed on a stratified sample of 307 drivers, to test the suggested hypotheses. Based on the results, five hypotheses have indirect relationships, four of which have a significant effect. Besides, the results show that driving fatigue partially mediates the relationship between the work schedule and driving performance and fully mediates in the relationship between work activities and driving performance. The nature of work and human factors is the most common reason related to road accidents. Therefore, the emphasis on driving performance and fatigue factors would thereby lead to preventing fatal crashes and life loss.

This research aims to develop a safety culture model by investigating the relationship between safety culture and driving performance. In previous studies, safety culture has been one of the factors that determine safety issues. These issues were then contextually transformed via a pilot study and organized in the form of a theoretical model. The data were collected from 307 oil and gas tanker drivers in Malaysia through questionnaire surveys. Consequently, structural equation models of partial least squares (PLS-SEM) were applied to statistically assess the final model of this study. The results showed that the implementation of safety culture contributes to driving performance at a substantial level; there is a strong association with an effect of 67.3%. The findings of this research would serve as a benchmark for decision-makers in the oil and gas transportation sector, as promoting an awareness of safety culture should boost the efficiency of drivers. This research fills a gap in knowledge by identifying that positive safety culture practices and mindset are direct antecedents for the improvement of driver performance and, thus, the avoidance of road accidents.

This study examines the impact of critical safety-management practices on the occurrence of occupational accidents by means of safety compliance in Malaysia’s oil and gas industry. This study employed a cross-sectional design, in which data were collected from oil and gas downstream operations in five states within Malaysia using the convenience-sampling technique. The valid data of 280 responses were analyzed with Smart-PLS, and the structural-equation-modeling technique was applied. The study’s outcome revealed that safety-management practices (i.e., safety training, workers’ involvement, safety communication and feedback, management commitment to safety, safety-promotion policies, and safety rules and procedures) were significantly associated with occupational accidents via safety compliance. Thus, this study is helpful for practitioners and researchers to understand the importance of safety-management practices in reducing occupational accidents.

Total quality management (TQM) is a systematic management technique for developing a process-driven culture inside an organization to achieve quality and customer and employee satisfaction. TQM has started to impact global business systems, and is extensively regarded as a management “revolution”. The implementation of TQM in the industrialized building system (IBS) in Malaysian projects has not been treated in much detail, although it is essential. This research intended to assess TQM adoption in IBS projects and identify how TQM drivers will help to overcome TQM-implementation challenges. This study utilized the mixed method by developing a semi-structured interview and survey, while the respondents were experts from TQM and IBS consulting firms. The content-validity approach was used, depending on 14 interviews and 28 responses to a distributed questionnaire. The findings indicate that TQM adoption of IBS projects is extremely poor. According to experts, local firms are still unable to execute TQM because they are reluctant to implement the TQM system as a strategy implementation across the construction process. Furthermore, according to the content validity ratio (CVR), there was an agreement that TQM would provide substantial benefits to IBS projects, such as offering cooperative associations, excellent communication, enhanced customer gratification, cost reductions, and productivity improvements. This study provided practical evidence of the fact that if the organizations adopted these 23 drivers of TQM they could overwhelm the challenges of TQM implementation in IBS projects. Thus, the stated factors were trustworthy, as indicated in the transcripts of interviews, and relying on the plurality of expert assessments. This study offers a valuable list of challenges and drivers for managers of the projects as guidelines to help them adopt TQM in IBS projects.

The Engineers in Society (EIS) course is a common course unique to Universiti Teknologi PETRONAS. However, every semester, the course receives 300 to 500 students, making managing and delivering it a challenging task. The EIS course is thus in need of a suitable mode of delivery where the teaching and learning process can cater to a large number of participants from a variety of programs. The aim of this study is to address the effect of Massive Open Online Courses MOOC factors implementation on the continuance intention of students. The study employed a survey that was designed from a literature review. The survey adopted a series of questions to gather information about the problem under investigation. One hundred forty-eight responses were collected from the students in different engineering, project and operation management, quality, sustainability, and entrepreneurship programs. In addition, partial least squares regression-structural equation modelling was used to analyze data. Based on the results, there is a significant impact of MOOC implementation factors on the continuance intention of students. Nevertheless, students showed a high intention to continue studying engineering in society courses online MOOC. Therefore, the current study provides practical evidence for management and lecturers of the university to enhance MOOC factors to ensure the high quality of teaching and enhance the continuance intention of students to study in a MOOC environment.
