Abstract

This study investigates the fatigue behavior of sugar palm fibre (SPF)-reinforced thermoplastic polyurethane (TPU) composites with varying fibre contents (10 wt%, 20 wt%, and 30 wt%). The composites were fabricated using extrusion followed by hot press moulding. Tensile tests were conducted in accordance with ASTM D638 to determine the ultimate tensile strength (UTS), and fatigue tests were performed under stress levels of 80%, 70%, 60%, and 50% of the UTS, following ASTM D7791. The results indicate that an increase in fibre content leads to a reduction in both tensile strength and fatigue life, likely due to poor interfacial bonding and fibre agglomeration. Fatigue life was found to be significantly higher at lower stress levels across all fibre contents. These findings provide valuable information about the potential and limitations of SPF/TPU composites for applications involving cyclic loading, particularly in lightweight and sustainable material applications

Abstract

Coastal public spaces play a strategic role in supporting social interaction, recreational activities, and urban environmental quality. However, the quality of public space is not solely determined by physical aspects, but also by the compatibility of spatial layout with users’ perceptions and behaviors. This study aims to evaluate the performance of public building spatial layout in the coastal open space of Ulee Lheue Beach, Banda Aceh City, based on users’ perceptions and behaviors. The research employed a qualitative evaluative approach through behavioral observation, in-depth interviews, and documentation. The findings indicate that Ulee Lheue Beach has strong visual and physical potential as a coastal public space, particularly in terms of openness and natural scenery. Nevertheless, the spatial layout has not fully responded to users’ activity patterns and needs, as reflected by limited spatial connectivity, unclear zoning, and the emergence of adaptive user behaviors in utilizing space informally. The study concludes that the performance of the public space layout at Ulee Lheue Beach remains suboptimal and requires reconfiguration that prioritizes user experience, perception, and behavior to create a functional, inclusive, and sustainable coastal public space.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) play a crucial role in Indonesia’s economic growth and social development by creating jobs, reducing poverty, and fostering an inclusive and resilient society. The primary aim of this research is to empirically examine the contribution of human, social, physical, financial, and natural capital towards enhancing the well-being of MSME workers. With a quantitative method, data from 250 respondents were collected by using a structured questionnaire based on measurements on a 1–5 Likert scale. The analysis was carried out using Structural Equation Modeling–Partial Least Squares (SEM-PLS). The findings reveal that all five types of capital have a positive and significant impact on the well-being of workers, with human capital and financial capital as the most dominant contributors, followed by social capital, physical capital, and natural capital. The model accounts for 67% of the variance in workers’ well-being with high predictive validity. These results validate that fostering welfare among MSMEs needs holistic solutions with individual, financial, social, infrastructure, and environmental aspects. The study offers actionable suggestions to policymakers, MSME managers, and development agencies to enhance holistic capital-based programs to foster employees’ welfare and productivity.
