The Effect of Epoxy Resin on the Compressive Strength of Short Laminated Bamboo Columns

Zulmahdi Darwis — 2025-05-30

The ongoing depletion of global timber resources has increasingly directed attention toward bamboo as a viable and sustainable structural alternative. This study investigated the influence of epoxy resin coatings on the compressive performance of short laminated bamboo columns. Three treatment conditions were evaluated: untreated (control), epoxy resin-coated, and externally reinforced with steel plates. The test specimens, manufactured using Dendrocalamus asper, were subjected to axial compression by SNI 03-3959:1995. Before testing, the physical and mechanical properties of both bamboo and steel reinforcement materials were characterized. Experimental results indicated that epoxy coating enhanced the average compressive strength by 2.54%, whereas steel plate reinforcement yielded a more substantial increase of 9.94% relative to the control group. One-way ANOVA analysis confirmed that only the steel-reinforced group demonstrated a statistically significant improvement in compressive capacity (p < 0.05). The observed failure modes revealed that the untreated and epoxy-coated specimens were prone to surface cracking and adhesive delamination, whereas the steel-reinforced columns exhibited a more localized damage with reduced deformation. It was concluded that although epoxy resin provided a modest enhancement, applying steel reinforcement significantly improved the axial load-bearing capacity of laminated bamboo columns. These findings underscore the structural potential of hybrid bamboo composites for sustainable construction applications.

Polycarpe Feussi — 2025-05-30

Supply chain postponement research has mainly focused on inventory management and lead time. The South African car industry is vital for the economy, driving job creation and economic development, thus addressing social issues such as inequality, unemployment, and crime. It is essential to meet client needs and proactively plan for sector growth, as this will create new job opportunities, drive economic progress, and improve the overall quality of life. This study investigates the relationship between assembly and order (ATO) and customer satisfaction in the South African automobile supply chain. Through the administration of a cross-sectional survey incorporating closed-ended questions, we obtained quantitative data from a sample of 375 individuals working at automobile dealerships. This data was then analyzed to evaluate the hypothesis that the ATO strategy can enhance customer satisfaction. Embracing this research is not just beneficial; it is a necessary step toward elevating service quality and fostering industry advancement. The findings revealed that customer input through the process could potentially improve customer satisfaction by improving five service quality variables, namely the tangibles: responsiveness, empathy, assurance, and reliability. Key stakeholders in this supply chain segment must prioritize enhancing customer relationship management and gaining deeper insights into end customers. Using the customer decoupling point with assembly-to-order (ATO) processes, along with targeted marketing and thorough market research, can achieve this goal. Focusing on customer satisfaction fosters loyalty, leading to more efficient marketing and superior relationship tactics, ultimately boosting the South African automobile industry’s market share and positively impacting job preservation and creation.

However, other food stall operations practices were not significantly related to operational challenges. In light of these findings, the study proposed strategies to boost profitability, operational efficiency, and resilience in food stall businesses, emphasizing the importance of strategic planning and best practices for the success and development of the food park industry.

Impact of Workload and Work-Life Balance on Aviation Safety at Soekarno-Hatta ATC

Giga Valtian Zepa — 2025-05-30

The increasing complexity of air traffic operations and the high cognitive demands placed on Air Traffic Controllers (ATCs) underscore the critical need to address factors affecting performance and safety. This study investigates the influence of workload and work-life balance (WLB) on safety outcomes among ATCs at Soekarno-Hatta International Airport through a Systematic Literature Review (SLR). This research is motivated by the growing concern over fatigue-related incidents in aviation, particularly in high-density airspace environments. By synthesizing empirical and theoretical findings from peer-reviewed literature, this study explores how excessive workload, rigid shift structures, and insufficient recovery periods contribute to cognitive fatigue, diminished attentional control, and elevated error rates. In contrast, structured WLB interventions—such as optimized shift rotations, mandatory rest periods, and supportive scheduling policies—are found to mitigate fatigue and enhance operational vigilance. However, the applicability of flexible working hours in ATC settings is constrained by the operational and regulatory frameworks of the aviation industry, particularly the standards set by the International Civil Aviation Organization (ICAO). This study contributes to the discourse on aviation human factors by advocating tailored fatigue risk management strategies and institutional support mechanisms to improve ATC well-being and ensure sustained aviation safety performance
