Analysis of Supplier Selection Based on Circular Economy in Fashion Retail Company Using the Fuzzy AHP Method
Get PDFCurrently, the linear economic model applied in Indonesia still relies on a "take-make-dispose" pattern that is unsustainable. The circular economic approach emphasizes efforts to extend the life cycle of raw materials and product resources, minimize waste, and support the regeneration of natural systems. This research analyze the important role of suppliers in supporting circular economy success in the fashion retail compay. The objective of this study is to select and validate priority criteria and sub-criteria as a performance ranking framework for fashion retail industry suppliers using the Fuzzy Analytic Hierarchy Process (AHP) method. The results of the Fuzzy AHP analysis indicate that quality, delivery, cost, cooperation ability, and environmental performance criteria are the priority for ranking supplier performance in the fashion retail industry, with the highest weight assigned to the quality criteria. This is followed by subcriteria such as rejection rate and product price, which carry the highest subcriteria weights. This is because there is still a significant percentage of defective goods produced due to raw materials that are easily damaged or not in line with circular economic concepts. These recommendations can aid in more effective decision-making in selecting fashion retail suppliers, considering circular economic aspects and sustainable performance

Strategic Landscape Planning Using THEMEQUAL for Sustainable Theme Park Project Success: Case BSD City Theme Park
Get PDFThe long-term success of theme parks is highly dependent on the integration of robust structural quality and exceptional service delivery. This study examines the influence of strategic landscape planning—using the THEMEQUAL framework—on project outcomes, focusing on BSD City Theme Park, Indonesia. Utilizing Structural Equation Modeling-Partial Least Squares (SEM-PLS) on responses from 400 theme park visitors, findings show that both structural quality (β = 0.36, p < 0.001) and service quality (β = 0.41, p < 0.001) have strong, significant effects on visitor satisfaction. Visitor satisfaction, in turn, is a significant predictor of project success (β = 0.47, p < 0.001), mediating the effects of both structural and service quality. Indirect (mediation) effects account for 62% of the total influence on project success. These results demonstrate that improved construction robustness and service standards significantly elevate satisfaction (mean index = 4.18/5), visitor loyalty, and positive word-of-mouth, underpinning sustainable project viability. Practical implications highlight that integrating strategic landscape planning and superior service quality is essential for achieving sustained competitive advantage in Indonesia’s growing theme park sector

Thermal and Flame Retardant Performance of Glass Fiber-Reinforced UPR Composites Modified with Boric Acid and Sodium Silicate
No full textThis study investigates the effect of sodium silicate (Na₂SiO₃) and boric acid (BA) as flame-retardant additives in unsaturated polyester resin (UPR) reinforced with E-glass fibres. The fire performance of the composites was evaluated based on varying additive concentrations by % volume fraction, using standardised testing methods in burning rate (BR) with ASTM D 635-22. Results indicate that Na₂SiO₃ contributes to fire resistance by forming a thermally stable, glass-like barrier, while BA proves more effective by interrupting combustion reactions and generating protective boron oxide residue. Notably, the combination of Na₂SiO₃ and BA produced a synergistic effect, resulting in a significant reduction in burning rate. Thermogravimetric analysis (TGA) further confirmed the enhanced thermal stability of the composite, particularly in the NB10 formulation with 2% Na₂SiO₃ and 8% BA, which demonstrated the slowest degradation at elevated temperatures. These findings suggest that optimising the ratio of Na₂SiO₃ and BA yields high-performance, fire-retardant composites suitable for applications demanding superior fire resistance and thermal durability, such as electric vehicle safety components
