This study conducts a Systematic Literature Review (SLR) to examine how key dimensions of digital service quality—namely system quality, ease of use, perceived value, and payment availability—shape customer loyalty among Generation Z culinary consumers, with customer satisfaction functioning as the mediating variable. Bibliometric mapping reveals that previous studies have predominantly focused on Millennials and Gen Y and have emphasized traditional service quality rather than digital service performance, indicating a significant research gap in Gen Z–specific digital consumption behavior. The SLR findings show that fast, secure, stable, and user-friendly digital systems strongly influence perceived value and user satisfaction, while the availability of digital payments such as QRIS and e-wallets enhances seamless transactional experiences. Customer satisfaction emerges as the primary psychological mechanism mediating the relationship between digital service quality and Gen Z loyalty, reflected in repeat purchases, positive word of mouth, and emotional attachment to digital culinary platforms. This study contributes theoretically by addressing existing research gaps and proposing a conceptual model of Gen Z loyalty grounded in digital experience.

Production quantity planning is a crucial component in the bottled water industry (AMDK) to ensure that consumer demand is met efficiently. Inaccuracies in determining the amount of production can lead to overproduction and supply shortages, which ultimately leads to increased operational costs and decreased customer satisfaction. This study applies the Sugeno fuzzy logic method to predict the amount of production based on two main variables, namely weekly demand and raw material stock. The analysis stages include the fuzzification process, the preparation of the rule base, inference using the zero-order Sugeno method, and defuzzification using the Weighted Average (WA) method. The data used is synthetic data that represents the operational conditions of the medium-scale bottled water industry. The results show that the Sugeno fuzzy system is able to produce production predictions that are adaptive and responsive to fluctuations in demand and stock availability. This model provides consistent and stable output, so it can help companies in determining the optimal production amount. These findings confirm that Sugino's fuzzy approach can be an effective decision support tool in bottled water production management, especially in the face of uncertainty and variability in market demand.

Total Quality Management (TQM) in education has become an important issue in line with increasing societal demands for quality educational services and student satisfaction. Improving educational quality not only depends on the curriculum but also on the effective implementation of quality management principles in educational institutions, including secondary schools, universities, and Islamic boarding schools. This article aims to provide a literature review on the concept, implementation, and impact of quality management on customer satisfaction in the context of Islamic education, addressing two research questions: (1) How are the concepts and practices of quality management implemented? and (2) What are the drivers and barriers to successful implementation?. The method employed is a qualitative literature review, with scholarly articles retrieved from Google Scholar and Publish or Perish (PoP) using the keyword “integrated quality management in education.” The search focused on publications from 2020 to 2025, yielding 30 initial articles. After screening and selecting based on relevance and focus on customer satisfaction, 5 main articles were analyzed in depth. The review revealed three main trends: (1) implementation of integrated quality management enhances service quality and student satisfaction; (2) leadership and curriculum management are key factors for success; and (3) continuous evaluation strategies and staff competency development promote stakeholder satisfaction. In conclusion, systematic quality management in education positively impacts customer satisfaction, and further research is needed to conduct comparative studies across institutions and to explore the integration of digital quality management systems.

This study employs the Systematic Literature Review (SLR) method following the PRISMA 2020 Statement guidelines to identify the main models and indicators used in measuring the performance of Micro, Small, and Medium Enterprises (MSMEs). The literature selection process includes the stages of identification, screening, eligibility assessment, and inclusion, resulting in ten articles from reputable Q1 international journals. The analysis reveals that the most frequently used performance measurement models are integrated performance models such as the Balanced Scorecard, Performance Prism, and models based on resource capability, customer, internal process, and financial perspectives. Commonly used indicators include sales growth, profitability, market share, customer satisfaction, process flexibility, technology adoption, and business sustainability. The study concludes that although financial measures remain dominant, non-financial dimensions—such as digital capability, stakeholder engagement, and internal process effectiveness—are increasingly important for MSMEs operating in the context of global market dynamics and digital transformation. The implications of this study provide theoretical contributions to the development of MSME performance measurement frameworks and offer practical guidance for MSME managers in selecting indicators that align with the characteristics of small and medium-sized enterprises.

This study analyzes the simultaneous and partial effects of Price (X1), Corporate Image (X2), and Service Quality (X3) on Customer Satisfaction (Y) in cargo shipping services at PT. Serasi Shipping Indonesia, Semarang Branch. The increasingly competitive maritime logistics sector demands a deep understanding of the determinants of business-to-business (B2B) customer satisfaction. Employing an explanatory quantitative design with a saturated population and sample of 100 corporate customers, data were processed using multiple linear regression analysis (SPSS v.22). The t-test results indicate that Price (t=3.813), Corporate Image (t=4.428), and Service Quality (t=2.398) individually have a positive and significant influence on Customer Satisfaction. Simultaneously (F-test, F=37.812), all three variables significantly influence satisfaction, explaining 52.7% of the satisfaction variance.
