In an increasingly competitive business world with ever-increasing customer demands for the quality of services and goods, customer satisfaction and loyalty have emerged as crucial issues in today's marketing management. Under such conditions, business entities must identify the key elements that shape satisfaction and how these contribute to building customer loyalty. This paper aims to examine the nature of study results on the determinants of satisfaction and loyalty through an evaluation of several recent empirical studies. Two key questions are addressed: which elements most strongly influence customer satisfaction, and what is the intermediary function of satisfaction in explaining the relationship between marketing variables such as service quality, cost, brand image, and trust with customer loyalty. The technique employed is a qualitative literature review through a search of articles using Google Scholar and Publish or Perish (PoP). Key terms used include customer satisfaction, customer loyalty, service quality, and trust. Of the 50 articles found in the initial phase, 15 met the inclusion standards and were thoroughly reviewed. The evaluation findings reveal three dominant patterns: service and product quality are the most stable factors driving satisfaction; cost and brand image serve as supporting factors; and trust acts as an important intermediary variable. This evaluation confirms that customer satisfaction is a key component in strengthening loyalty. Future studies are recommended to expand the scope of business sectors, use a more comprehensive structural framework, and utilize a wider variety of methodological techniques.

Although Experience Quality has been extensively researched, comprehensive studies remain limited. This research aims to conduct a Systematic Literature Review (SLR) and bibliometric analysis of existing empirical work on Experience Quality. The methodology used is SLR, with data collected from the Scopus database using the search term "Experience Quality" in the title, abstract, and keywords. This search yielded 1,297 publications from 1965 to 2025 (evaluated on October 24, 2025). The data were analyzed bibliometrically using VOSviewer. The findings confirm that experience quality has a significant effect on brand perception and customer satisfaction, which consequently impacts customer loyalty. Practically, this implies that brand and service managers must treat experience quality as a strategic variable, as good products or services alone are insufficient for long-term loyalty. Socially, positive experiences are shown to strengthen social networks, increase community involvement, and promote inclusion. This research is limited by its reliance solely on the Scopus database; future research should integrate additional databases, such as Web of Science, for broader generalization. Despite the global development of this topic, in-depth, structured studies are scarce. This research is valuable and original as it provides a comprehensive summary and a research roadmap through SLR and bibliometric analysis.

The rapid expansion of e-commerce in Indonesia has resulted in a significant rise in the number of customer reviews, which serve as a valuable source of insight for understanding consumer satisfaction. This study aims to classify or identify sentiments from product reviews on the Tokopedia platform into three categories, using the Support Vector Machine algorithm. The classification method data were ethically collected through web scraping and include review text, ratings, and the number of “likes.”  The preprocessing stage involved several NLP techniques such as pre-procesesing data representation was generated using the Term Frequency–Inverse Document Frequency method, while the issue of class imbalance was addressed using the Synthetic Minority Over-sampling Technique.  Based on the test results, the SVM model achieved an accuracy of 79.48% on the test data using a linear kernel, showing the best performance in classifying positive sentiments. However, the classification of neutral and negative sentiments still requires improvement. This study demonstrates that the combination of the TF-IDF method, additional numerical features, and data balancing techniques can produce an an efficient sentiment analysis model within the e-commerce domain.

The digital era demands that organizations be fast-moving, adaptable, and innovative. With the advancement of information technology, changes in work methods, global competition, and stakeholder demands are becoming increasingly complex. Knowledge Management (KM) plays an important role as a strategic mechanism for identifying, acquiring, storing, sharing, and utilizing knowledge to improve organizational effectiveness and efficiency. In this context, knowledge management becomes one of the important elements for organizations to enhance performance. Knowledge management is not just about collecting data or information, but how organizations can store, share, create, and utilize knowledge to gain a competitive advantage. This article aims to analyze the importance of knowledge management for organizational performance in the digital age, including how the digital era changes the dimensions of knowledge management, how knowledge management contributes to organizational performance, the challenges faced, and their implications. The data obtained for this study were gathered from observations thru interviews with relevant parties and a literature review study by examining the results of empirical research from the past five years (2020–2025). The method used was descriptive literature analysis of 15 scientific articles from accredited national journals. The analysis focuses on the relationship between knowledge management dimensions (knowledge creation, storage, sharing, and application) and organizational performance indicators (financial performance, innovation, productivity, and customer satisfaction). The study results show that the implementation of knowledge management significantly contributes to improving organizational performance, both directly thru increased efficiency and effectiveness of work processes, and indirectly thru strengthening a culture of innovation and organizational learning. This article asserts that an organization's success in the digital age is not solely determined by its ability to adopt technology, but also by its ability to manage and leverage knowledge as a strategic resource. Therefore, knowledge management needs to be systematically integrated into the organization's digital strategy, accompanied by strengthening a learning culture, human resource training, and adaptive information technology systems.

In the context of modern organizations, performance can no longer be measured solely through short-term target achievements. A strong foundation of quality culture is required to ensure sustainable performance. This study aims to examine the relationship between quality culture and organizational performance sustainability through a modern managerial approach. The method used is descriptive qualitative, employing literature studies and conceptual analysis of theories related to quality management, organizational culture, and performance sustainability. The findings indicate that quality culture holds a strategic role in shaping work behavior, strengthening management systems, and fostering continuous innovation. The application of quality values—such as commitment to continuous improvement, customer orientation, and consistency in process control—contributes to the creation of a productive work environment that is responsive to change. Integrating quality culture into all aspects of the organization also enhances operational efficiency, reinforces teamwork, and promotes data-driven decision-making. These aspects lead to greater performance consistency, improved customer satisfaction, and long-term competitive advantage. Therefore, quality culture does not merely serve as a behavioral guideline but becomes a fundamental pillar in building an adaptive, innovative, and sustainable organization capable of navigating an increasingly complex business environment.

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.

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.

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.

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.
