The physical properties of peat from the present study were obtained on site and in the laboratory, including degree of humification, moisture content, organic content, fibre content, specific gravity, liquid limit, linear shrinkage, and pH. The data obtained in this study and other tropical peats in Malaysia were compiled to identify their correlations. The correlation results reveal that with an increase in organic content, there is also an increase in value of moisture content, while the value of specific gravity reduces. Furthermore, as the bulk density of peat increases, the value of organic content reduces. Also, the moisture content, organic content, and fibre content of peat decrease with the increasing value of degree of humification. The correlations between different peat soil index properties have R 2 values ranging from 0.75 to 0.85, showing that the peat soil index properties are consistent with findings from previous studies, in which comparable trends are found. Thus, these correlations are expected to be useful for researchers and engineers to understand the peat soil's preliminary behaviour.

However, no systematic literature review of the research trends in augmented and virtual reality (AR/VR) for Occupational Safety and Health (OHS) training has been carried out. The authors conducted a comprehensive review of the relevant literature published between 2016 and 2020. This analysis was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The Scopus database contained 1031 records. However, only 12 papers matched the inclusion criteria and were included in this review. According to the findings, the use of augmented and virtual reality for safety training and rehabilitation has been progressively growing. With robust research trends in this field—in the post-pandemic era, the use of augmented reality and virtual reality games has promising potential, especially for safety training and r...

However, the outbreak of coronavirus (COVID-19) has caused learning institutions to embrace online learning due to the lockdown and campus closure. This paper presents an analysis of students' feedback (n=354) from the Centre of Pre-University Studies (PPPU), Universiti Malaysia Sarawak (UNIMAS), Malaysia, during the transition to fully online learning. Three phases of online surveys were conducted to measure the learners' acceptance of the migration and to identify related problems. The result shows that there is an increased positivity among the students on the vie of teaching and learning in STEM during the pandemic. It is found that online learning would not be a hindrance, but blessing towards academic excellence in the face of calamity like the COVID-19 pandemic. The suggested future research direction will be of interest to educators, academics, and researchers' community.
