Abstract

Sustainability of water supply services hold contributes to human well-being with individual preferences. So, there is need to assess for the public from various levels of water services in an effort to ensure water provision with the aim of achieving customer satisfaction in its use so that it can build their own loyalty. So therefore, this study was conducted to determine how water quality and service effect consumer loyalty using the Structural Equation Modeling (SEM) by looking for variables that influence quality and success in achieving user loyalty by forming a diagram of the relationship between variables and indicators, confirmatory analysis factors for exogenous and endogenous variables in the initial model, data normality tests and outlier evaluations. The model fit test in this study uses several criteria, including Chi Square, GFI, TLI, CLI, AGFI and RMSEA. Based on the results of this study, it shows that (1) the variable (CS) Consumer Satisfaction value of 0.768, meaning that the variable (CS) Consumer Satisfaction can be explained by (WQ) Water Quality (SQ) Service Quality with a percentage value of 76.8% while 24.2% can be explained by other variables not examined in this study. (2) not all antecendent variables have a significant influence on the consequent variables. Also, not all hypotheses are accepted. All antecedent variables cannot explain the consequent variables because the R2 value is less than 0.5.

Abstract

This study aims to develop and validate an integrated Risk Management (RM) and Circular Economy (CE) model for enhancing SME Resilience (SR) and Sustainable Competitiveness (SC) in agroindustrial SMEs. The research employed a mixed-methods approach involving observations, interviews, Focus Group Discussions (FGD), and questionnaire surveys conducted on 157 respondents from agroindustrial SMEs producing banana chips in East Luwu, Indonesia. Data analysis was performed using Structural Equation Modeling–Partial Least Squares (SEM-PLS). The results revealed that RM positively affects SR with a path coefficient of 0.384, while CE demonstrated the strongest influence on SR with a coefficient of 0.451. Furthermore, SR significantly influenced SC with a coefficient value of 0.612. Mediation analysis confirmed that SR significantly mediates the relationships between RM and SC (0.235) as well as CE and SC (0.276). The findings indicate that integrated risk management and circular economy practices improve operational adaptability, sustainability, and long-term competitiveness in agroindustrial SMEs.
