Improving Graduate Quality and Public Satisfaction through Internal Quality Assurance. Al-Tanzim: Jurnal Manajemen Pendidikan Islam, 9. , 1261-1273s. INTRODUCTION Pesantren is the oldest Islamic educational institution in Indonesia and plays a strategic role in shaping students' character, morals, and religious competence (Jubba et al. , 2021. Mujahid, 2021. Rofiah et al. , 2. The existence of Islamic boarding schools in various regions, including Tasikmalaya, is not only a center for the transmission of Islamic knowledge but also a center for social development, daAowah, and community empowerment. In recent decades, public demands for the quality of Islamic boarding school graduates have increased (Kosim et al. , 2023. Muhajir, 2022. Roqib, 2. Parents and the community hope that pesantren will produce graduates who are knowledgeable, moral, and possess relevant life skills in the midst of modern complexity. This condition requires Islamic boarding schools to strengthen their quality management systems, including by implementing Internal Quality Assurance Standards (SPMI) as an educational quality management instrument (Efendi, 2022. Lathifah et al. , 2022. Sofyani et al. , 2. Historically. Islamic boarding schools have had a tradition of education based on the yellow book, kiai examples, and a strong pattern of worship habits. However, the development of the national curriculum, the digitalization of education, and the increase in the competency demands of graduates have made Islamic boarding schools adapt without losing their traditional identity (Erstad et al. , 2021. Hyydal & Haldar, 2022. Zahraini et al. , 2. Some Islamic boarding schools have sought to integrate formal curricula with traditional curricula to produce graduates with balanced academic, spiritual, and social abilities (Ramli et al. , 2025. Sheva Bayu Firmansyah & Zaenal Abidin, 2024. Thoyib, 2. Several previous studies have examined the dynamics of educational quality in Islamic boarding schools. Badrudin . emphasized that the modernization of pesantren governance is still facing structural challenges in Research by Hanif & Indianto . shows that integrating the science-Islamic curriculum improves learning quality. Rohman et al. highlight the weak management of yellow book learning in the face of modernization demands. Meanwhile. Hakim et al. explained that pesantrens have great potential to improve the Human Development Index (HDI) if supported by effective quality management. The results of the study show that improving the quality of pesantren education is a strategic issue, but studies specifically comparing the implementation of SPMI across pesantrens remain limited. Al-Tanzim : Jurnal Manajemen Pendidikan Islam Vol. 09 No. : 1261-1273 Available online at https://ejournal. id/index. php/al-tanzim/index The limitations of previous research are evident in the absence of studies that combine quantitative and qualitative data to explain variation in the application of SPMI and its impact on the quality of graduates and community In addition, previous research has not examined in depth how the values of turats, spirituality, and life skills are integrated into SPMI practices in the context of Islamic boarding schools. This gap underscores the need for a comparative study that not only measures SPMI's effectiveness through statistics but also understands its meaning from the perspectives of kiai, teachers, and This study offers a novel comparative analysis of two large Islamic boarding schools in Tasikmalaya, namely Sukamanah and Sukahideng, using a mixed-methods, sequential, explanatory approach. This study not only assesses the influence of SPMI on the quality of graduates and community satisfaction, but also interprets the dynamics of SPMI implementation through curriculum practices, character development, spirituality, and the social role of Islamic boarding schools. Thus, this study provides a new perspective on how SPMI can function within the context of Islamic boarding schools, grounded in tradition and spiritual values. This study aims to analyze in depth the implementation of SPMI in two Islamic boarding schools and their impact on the quality of graduates and community satisfaction. The research focuses on the identification of pesantren quality strategies, curriculum dynamics, the quality of student development, and social contributions that affect public perception of pesantren. This study is important because pesantren is an educational institution that has a unique position in the national education system. The effectiveness of SPMI in pesantren is not only about improving academic competence but also affects social legitimacy, student independence, and the sustainability of the pesantren's role in society. The results of this research are expected to strengthen the quality assurance model of Islamic boarding schools, making it integrative, applicable, and in harmony with Islamic traditions and the needs of the modern world. RESEARCH METHOD This study employed a Sequential Explanatory Mixed-Methods Design, consisting of two consecutive phases: a quantitative phase followed by a qualitative phase aimed at explaining and deepening the statistical findings (Antony et al. , 2023. Chen et al. , 2023. Thornberg et al. , 2. This design was selected because the influence of the Internal Quality Assurance System (SPMI) on graduate quality and community satisfaction involves complex institutional dynamics that require both measurable patterns and contextual interpretation from key stakeholders. The quantitative phase involved 457 respondents, comprising 222 from Sukamanah Islamic Boarding School and 235 from Sukahideng Islamic Boarding School, selected using a proportionate sampling After identifying the quantitative trends, the qualitative phase was conducted through semi-structured interviews with kyais, senior teachers, quality assurance managers, and community leaders, purposively selected based on their relevance to the findings (Ahmad & Wilkins, 2025. Andrade, 2021. Al-Tanzim: Jurnal Manajemen Pendidikan Islam Vol. 09 No. : 1261-1273 Available online at https://ejournal. id/index. php/al-tanzim/index Stalmeijer et al. , 2. Integration occurred at the final stage using a metainference procedure to merge numerical results and narrative explanations into a coherent interpretation (Rana & Chimoriya, 2025. Younas et al. , 2023, 2. The quantitative phase began with the distribution of standardized questionnaires measuring SPMI implementation, graduate quality, and community satisfaction. Instrument validity was ensured through expert judgment and construct validity tests using outer loadings and Average Variance Extracted (AVE), while reliability was assessed through Cronbach's Alpha and Composite Reliability ( and CR > 0. (Cheung et al. , 2024. Frane & Hill, 1976. Haji-Othman & Yusuff, 2. Respondents were drawn from three strataAifinalyear students, teachers, and parentsAiusing proportionate stratified sampling to achieve balanced representation. After the quantitative analysis was completed, the qualitative phase was conducted through semi-structured interviews with purposively selected key informants whose roles and insights were essential for explaining the statistical relationships. The interviews explored themes such as educational vision, learning traditions, spiritual practices, character development, and community perceptions. Supplementary data were obtained through observations and institutional documents to strengthen contextual understanding and enhance data credibility. Quantitative data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM), including evaluation of the outer model . onstruct validity and reliabilit. , inner model . ath significance testin. RA values, and effect sizes (Fauzi, 2022. Frane & Hill, 1976. Legate et al. , 2. This technique was chosen for its suitability for analyzing latent-variable relationships in medium-sized samples. After identifying the quantitative pathways, qualitative data were analyzed using thematic analysis following Braun and Clarke's stages: open coding, categorization, and theme development in alignment with the statistical outcomes. Credibility was ensured through member checking, source triangulation, and audit trails. Integration of both data strands occurred through sequential explanatory integration, linking each quantitative finding with qualitative narratives that clarified or expanded the numerical patterns. This approach generated comprehensive meta-inferences that reveal how SPMI shapes graduate quality and community satisfaction within the socio-cultural context of Islamic boarding schools. Quantitative data were analyzed using Partial Least Squares (SmartPLS) to examine the structural relationships between Internal Quality Assurance (SPMI). Graduate Quality, and Community Satisfaction. The analysis focused on estimating the path coefficients () and the coefficients of determination (RA) for each endogenous variable (Fauzi, 2022. Frane & Hill, 1976. Legate et al. , 2. Path significance was assessed using the bootstrapping procedure provided by SmartPLS, which generated standardized values and p-values to determine the strength and direction of the relationships among variables (Sim et al. , 2. Model fit was evaluated primarily through RA values, reflecting the proportion of variance in Graduate Quality and Community Satisfaction explained by SPMI at both Islamic boarding schools. Since the available data in this study emphasize structural relationships, the analysis was limited to interpreting path estimates Al-Tanzim : Jurnal Manajemen Pendidikan Islam Vol. 09 No. : 1261-1273 Available online at https://ejournal. id/index. php/al-tanzim/index and RA outcomes, without conducting outer-model assessments such as validity, reliability, or effect size calculations (Amadi, 2. This approach ensured that the quantitative phase accurately reflected the empirical results while remaining consistent with the field data's scope. RESULTS AND DISCUSSION Result Quantitative Analysis Measurement Model and Reliability Analysis The measurement model was assessed using SmartPLS 4. 0 with a bootstrapping procedure of 5000 subsamples.

Al-Tanzim : Jurnal Manajemen Pendidikan Islam Vol. 09 No. : 1261-1273 Available online at https://ejournal. id/index. php/al-tanzim/index Discussion The integration of quantitative and qualitative findings demonstrates strong alignment between institutional practices and the measurable outcomes of graduate quality and community satisfaction at Sukamanah and Sukahideng Islamic Boarding Schools. The quantitative results show that SPMI significantly influences graduate quality at both institutions, with Sukamanah displaying a slightly higher path coefficient (=0. RA=0. than Sukahideng (=0. RA=0. Meanwhile, community satisfaction is more strongly influenced at Sukahideng ( = 0. RA = 0. These statistical patterns align with qualitative narratives that emphasize the schools' focus on turats, an integrative curriculum, and spiritual formation. Informants consistently described practices such as daily Quran recitation, bandonganAesorogan methods, and ta'dib-based moral education as crucial components of student development. These narratives illustrate why SPMI yields strong academic and moral outcomes, confirming that structured quality assurance is deeply embedded in everyday practices. The convergence of data suggests that SPMI is not merely administrative but serves as a lived educational culture that shapes student competence and institutional credibility in the community. The combined findings align with prior studies that emphasize the role of internal quality assurance in improving educational outcomes in Islamic Research by Jubba et al. highlights that quality assurance strengthens institutional culture and stakeholder trust, as evidenced by the strong coefficients observed in both pesantrens. The qualitative insights reinforce those of Rofiah et al. , who found that pesantrens with structured spiritual routines and integrated curricula produce graduates with higher academic and moral competence. However, this study extends the existing literature by illustrating distinct institutional orientations: Sukamanah excels in academic strengthening through rigorous mastery of kitab kuning, while Sukahideng emphasizes community-oriented outcomes, aligning with Mujahid's . findings regarding pesantren's social roles. The mixed-methods synthesis provides nuance absent in prior single-method studies, showing not only that SPMI works but explaining how leadership practices, cultural traditions, and spiritual routines drive measurable improvements. This helps fill a gap in pesantren governance research, particularly regarding the interaction between quality assurance systems and traditional learning ecosystems. The findings interact closely with organizational quality theories and Islamic educational principles. Deming's model of continuous improvement is reflected in the integration of routine evaluation, curriculum refinement, and teacher development within both pesantren (Ahmad & Wilkins, 2025. Hakim et , 2025. Rohman et al. , 2. The qualitative results, such as the practice of ta'dib, structured worship, and intellectual halaqah, support Al-Attas' theory of adab, which posits that moral order is a prerequisite for intellectual excellence. The quantitative results, with strong coefficients, indicate that these practices contribute to systematic outcomes predicted by organizational theoryAi specifically, that strong internal processes produce consistent external outcomes. Additionally, the convergence of findings supports sensemaking theory (Younas Al-Tanzim: Jurnal Manajemen Pendidikan Islam Vol. 09 No. : 1261-1273 Available online at https://ejournal. id/index. php/al-tanzim/index et al. , 2. , which holds that teachers and kiai interpret SPMI not as bureaucratic compliance but as meaningful educational guidance. This study, therefore, not only confirms theoretical propositions but also expands them by demonstrating how traditional Islamic pedagogies operationalize modern quality assurance frameworks, offering a hybrid model of institutional quality rarely documented in contemporary literature. This study contributes significantly to the field of Islamic education management by demonstrating how mixed-methods research produces a more comprehensive understanding of quality assurance in pesantren. The convergence of quantitative and qualitative data shows that SPMI influences not only academic performance but also community trustAian outcome rarely quantified in previous studies. By explaining how practices such as ta'dib, bandonganAesorogan, structured spiritual routines, and integrative curriculum drive measurable improvements, this research expands theoretical discussions on hybrid educational quality systems. The study also advances practical discourse by showing that traditional learning ecosystems can successfully integrate with modern quality assurance frameworks without losing their The use of mixed methods yields a layered explanation that goes beyond statistical association, offering insights into mechanisms, cultural dynamics, and spiritual underpinnings that shape institutional effectiveness. This provides a valuable model for future studies seeking to bridge organizational theory. Islamic educational philosophy, and empirical evidence. CONCLUSION This study examined how the Internal Quality Assurance System (SPMI) shapes graduate quality and community satisfaction in Sukamanah and Sukahideng Islamic Boarding Schools through an integrated mixed-methods design, revealing that SPMI functions as both a measurable organizational system and a culturally embedded pedagogical practice. The quantitative results indicate strong associations between SPMI and key outcome variables. At the same time, qualitative insights demonstrate how practices such as ta'dib, classical text mastery, structured worship, and life-skills formation give substantive meaning to quality assurance within the pesantren's moralAespiritual ecosystem. Together, these findings extend existing theories of educational quality by showing that continuous improvement models can align with Islamic intellectual traditions, particularly Al-Attas' concept of adab, while also providing empirical support for organizational quality theory through culturally grounded Practically, the study highlights the need for strengthened teacher development, integrated curriculum design, and alumni-driven quality Despite its contributions, the research is limited by its regional focus, sample size, and cross-sectional approach, which constrain broader Future studies should employ longitudinal tracking, larger multisite samples, and comparative analyses across pesantren types, as well as develop spirituality-based SPMI frameworks to refine the theoretical architecture of quality assurance in Islamic education.
