Abstract

Product quality has a significant influence on purchasing behavior. The better the quality of Wardah beauty products, the more purchasing behavior on Wardah beauty products will increase, and vice versa, the worse the quality of Wardah beauty products, the more purchasing behavior will decrease. The results of this study are in accordance with previous research by Rahayu & Sudarmiatin (2022) showing that attractiveness has a significant influence on purchasing behavior. The results of this study are also in line with the statements of Rajalakshmi & Golden (2023) and Khasanah et al. (2023) showing that product quality can significantly influence consumer purchases. The cosmetics industry in Indonesia has always experienced significant growth and has the potential to have a large market in the ASEAN market, this potential then causes competitive market competition so it is important for managers to study consumer behavior. This study aims to test the effect of influencer experience, trust, attractiveness, content usefulness, product price and product quality on purchasing behavior in Wardah consumers. The study was conducted quantitatively on 177 respondents who were users of Wardah beauty products. The results of the study show that influencer experience, attractiveness and product quality have a significant influence on purchasing behavior, but influencer trust, influencer content usefulness and product price do not significantly influence purchasing behavior

Abstract

Plant–soil–microbe interactions underpin nutrient cycling, ecosystem productivity, and resilience under environmental change. Despite advances in rhizosphere ecology and molecular biology, integration between biomolecular processes and ecosystem-level dynamics remains fragmented. This study aims to develop and empirically validate a mechanistic framework linking gene expression, metabolite exchange, microbial functional traits, and ecological outcomes across controlled and field contexts. A multi-scale design combined greenhouse factorial experiments with field validation, integrating metagenomics, metatranscriptomics, metabolomics, soil nutrient assays, and ecological network modeling. Structural equation modeling and multivariate analyses were applied to identify causal pathways among root exudation, microbial functional gene abundance, nutrient availability, and plant biomass. Results demonstrate that functional gene abundance (? = 0.46, p < 0.001) and root metabolite diversity (? = 0.39, p < 0.01) significantly predict plant productivity, while network analysis identifies organic acids and nitrogen-fixing taxa as keystone interaction nodes. Drought treatments induced coordinated upregulation of stress-response genes and metabolite adjustments, partially buffering productivity losses. The study concludes that rhizosphere resilience emerges from tightly coupled biomolecular and ecological feedback mechanisms. Integrative multi-omics combined with ecological modeling enhances predictive understanding of ecosystem function under environmental variability.
