The growing demand for integrated Islamic schools to deliver high-quality education that emphasizes both academic excellence and character development has encouraged the adoption of Total Quality Management (TQM) as a modern and relevant management approach. TQM is considered appropriate because it highlights continuous improvement, active involvement of all school members, and a strong focus on customer satisfaction within the educational context. This study aims to analyze the implementation of TQM in improving school quality at three integrated Islamic junior high schools: SMP IT Al-Khoiriyyah, SMP IT Nurul Islam, and SMP IT Baitul Anshor. The research employed a qualitative method using a multi-case study design. Data were collected through in-depth interviews, direct observations, and document analysis involving principals, vice principals, teachers, educational staff, students, and parents. Data analysis followed the stages of reduction, presentation, and inductive conclusion drawing. The findings indicate that TQM implementation in all three schools followed four main stages: planning, organizing, implementation, and monitoring and evaluation. During planning, TQM principles were embedded in School Work Plans, the PDCA cycle was applied, and stakeholders were actively involved. Organizing focused on quality-based structures, clear task distribution, and teamwork. Implementation included quality-oriented learning, teacher development, extracurricular activities, and integrated Islamic programs, while monitoring involved supervision, internal audits, evaluation meetings, and feedback systems. Supporting factors included visionary leadership, Islamic work culture, and parental support, while challenges involved limited facilities, uneven teacher competencies, and heavy workloads.

This study investigates the structural relationships among Product Quality (PQ), Brand Image (BI), Word of Mouth (WOM), and Repurchase Intention (RI) to empirically understand the sequential mechanisms driving consumer loyalty in a highly competitive market. Grounded conceptually in the Stimulus-Organism-Response (S-O-R) paradigm, the research posits that PQ acts as an external antecedent influencing RI through the mediating cognitive and behavioural constructs of BI and WOM. Data were collected from a sample of 187 Weber product consumers in Surabaya and analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM). The empirical results confirm all hypothesized direct and indirect relationships. Specifically, PQ significantly and positively influences both BI (β=0.337, p<0.000) and WOM (β=0.351, p<0.000). Furthermore, both BI and WOM significantly predict RI, with WOM (β=0.498, p<0.000) demonstrating a markedly stronger effect compared to BI (β=0.414, p<0.000). The model successfully explains a moderate 57% of the variance in Repurchase Intention. These findings underscore the strategic imperative for management to prioritize superior product quality, which organically fosters a positive brand perception and stimulates potent word-of-mouth promotion identified as the most critical driver of repeated purchases. Future research is encouraged to integrate additional affective factors, such as customer satisfaction or perceived price fairness, to enhance the explanatory power of the consumer loyalty model.

The quality of education is an important issue that requires an integrated and sustainable management system. One approach that is widely used is Total Quality Management (TQM), which focuses not only on achieving academic standards, but also on the satisfaction of all education stakeholders. Although many studies have discussed IQM, a synthesis is still needed to see how IQM has been applied over the past five years and its contribution to customer satisfaction in education. Therefore, the research questions asked are: (1) how has IQM research in education developed from 2020 to 2025, and (2) to what extent has it contributed to customer satisfaction in education? This article uses a qualitative method based on a literature review (LR). The search process was conducted through the Google Scholar and Publish or Perish databases using the keywords “Integrated Quality Management in Education.” The search yielded 20 articles, which were filtered into 18 relevant articles and further analyzed into 5 main articles. The review results show three main themes: quality system planning and integration, quality culture-based managerial strategies, and quality assurance oriented towards stakeholder satisfaction. The conclusion confirms that IQM contributes significantly to improving quality and customer satisfaction in education. Further research is recommended to test the empirical relationship between IQM practices and stakeholder satisfaction at various levels of education.
