Introduction Education is a key pillar in national development and a significant factor in determining the quality of human resources and the progress of a nation. As mandated in the Indonesian National Education System Law No. 20 of 2003, education aims to develop students' potential to become individuals who are faithful and devout to God Almighty, virtuous, healthy, knowledgeable, capable, creative, independent, and democratic citizens who are responsible. Quality education is crucial for improving 134 | AJIS : Academic Journal of Islamic Studies, vol. 10, no. individuals' quality of life, which can contribute positively to the nation1. The quality of education is heavily influenced by the management of educational resources, which includes educational management, teacher competence, and the school environment. Quality education is measured by exam results or graduation rates and the quality of planning, implementation, and evaluation carried out by educational institutions. Tjandra2 reveals that the quality of education includes input, process, output, and outcome as part of the educational system evaluation. In this context, the importance of the managerial competence of school principals, the pedagogical competence of teachers, and school culture are key elements that mutually influence the improvement of educational quality. The managerial competence of school principals is a critical factor in achieving the established educational goals. Principals are central in planning, organizing, motivating, and supervising all school activities to achieve the desired outcomes3. Good managerial competence can lead to more effective planning, optimal resource management, and better educational outcomes. Research by Harahap & Rusdinal4 , and May et al. shows that the managerial competence of school principals greatly influences the quality of school education. In addition to principals, teachers also play a crucial role in improving educational quality. Teachers' pedagogical competence includes managing a student-centred learning process, curriculum development, and learning outcome evaluation6. A teacher with strong pedagogical competence can organize learning materials effectively and improve the teaching and learning process with varied and 1 Aminatul. Zahro.

Research by Kustanti7 indicates that pedagogical competence positively affects educational quality, where teachers with good pedagogical competence can deliver material effectively and engage studentsAo interest. In addition to the managerial competence of school principals and teachers' pedagogical competence, school culture also plays a significant role in creating a conducive learning environment. A positive school culture can improve the quality of interactions between students and teachers and create a climate that supports learning. Sukandari8 explains that school culture encompasses the values and behaviours applied in everyday life at school. A positive culture can enhance students' learning motivation and create a comfortable academic and non-academic development atmosphere. However, an unhealthy school culture can hinder studentsAo development and reduce the quality of education. Based on data from the 2024 education report card of SMP Negeri Sub Rayon 01. Jepara Regency, the education process and output indicators are generally good, but some still need improvement. Overall, student literacy achievement reached 79. 51 and numeracy 74. 57, but indicators of student character and the quality of teaching were still in the lower average scores . 97 and 61. This data indicates the need for greater attention to deeper aspects of teaching and student character Observations also indicate a need to improve teachersAo pedagogical competence in applying more diverse teaching methods and strengthen school culture that supports improving teaching quality. Principal performance evaluations show that principals' managerial competence is already quite good, though supervision still requires The improvement of educational quality at SMP Negeri Sub Rayon 01. Jepara Regency, depends on the managerial competence of the principal and teachersAo pedagogical competence and on strengthening the school culture. The synergy between these three elements is essential in creating a conducive educational climate and producing quality graduates.

According to Aminatul9, the quality of education refers to the ability of educational institutions to manage existing resources to maximize students' learning potential. In a broader sense, the quality of education encompasses effective management aimed at producing graduates with high academic and non-academic Herawan11 also mentions that the quality of education is the degree of excellence in the effective and efficient management of education to achieve excellence in academic and extracurricular aspects. As stated by Arbangi12, the quality of education also includes the outcomes achieved by educational institutions in preparing students to adapt to changing times. Quality education integrates input, process, and output, which must be carried out, planned, and structured to achieve the desired objectives13. In line with this. Surya14 states that the quality of education means the process and results of education according to specific criteria and standards set within the national education system. Supardi15 identifies the dimensions of educational quality, which include three main components: input, process, and output. Input refers to the factors required for the educational process, such as teacher qualifications, school facilities, and other supporting resources. The educational process is the interaction between school resources that creates a conducive and effective learning situation. Educational output is measured by school performance, which can be seen in student achievement and the attainment of learning objectives. Mulyasa 16 also mentions that indicators of educational success can be seen from the achievements students obtain in terms of knowledge, skills, and character developed through the educational process.

School principals' managerial competence is crucial in improving educational quality. As educational managers, principals are responsible for ensuring educational goals are achieved. According to Sagala17, the managerial competence of school principals includes the knowledge, skills, and attitudes required to perform effectively as education This consists of the ability to plan, organize, direct, and supervise all school activities18. The managerial competence of school principals can be a driving factor in optimizing teacher and staff performance and improving the quality of learning. The managerial competence of principals includes aspects such as the development of the schoolAos vision, strategic planning, resource management, and oversight of the implementation of educational policies at the school19. principal with strong managerial competence can create a conducive and effective learning environment and motivate teachers and staff to achieve optimal educational goals. The managerial competence of school principals covers several critical dimensions in managing schools. Donni and Rismi20 state that principals must be able to plan, organize, lead, and supervise all school activities. This includes managing human resources, facilities and infrastructure, and the school and community Iskandar21 adds that principals' skills in policy design, resource management, and staff leadership are key to realizing the school's vision and mission. Pedagogical competence is a skill that teachers must have in managing the learning process, designing learning activities, and evaluating student learning outcomes. According to Wijaya22, pedagogical competence includes understanding learning theory, developing and implementing learning skills, and assessing learning 17 Sagala.

This competence is vital for teachers to achieve educational goals and enhance the quality of the learning process in the classroom. Mulyasa23 explains that teachersAo pedagogical competence consists of lesson planning, lesson implementation, and learning evaluation. Teachers with good pedagogical competence can design practical lessons, conduct meaningful learning interactions, and evaluate how well learning objectives have been achieved. Ramayulis24 also states that pedagogical competence includes teachersAo ability to understand student characteristics, design and implement effective learning, and systematically evaluate student learning outcomes. This competence also involves the development of students' academic and non-academic School culture is a system of values, norms, and behaviours that all community members accept and practice. This culture shapes the identity and character of the school and creates an atmosphere that supports the learning process. Suhadisiwi25 states that school culture serves to improve the quality of education because it can influence the behaviour and interactions among school members during the learning Purnomo26 also emphasizes that school culture reflects the values that guide behaviour and serve as solutions to problems faced by school members. Rusdiana27 identifies the dimensions of school culture, which include individual autonomy, organizational structure, support, identity, and appreciation for performance. Darmawan28 adds that school culture also includes religious, disciplinary, hardworking, and creative dimensions essential in creating a school environment that supports quality learning.

According to Creswell in Wahidmurni29, quantitative research aims to test the relationships between variables by collecting data in numerical form that can be analyzed using statistical procedures. The type of research used is correlational research, which determines the relationship between two or more variables30. This study explores the effect of the managerial competence of school principals, teachers' pedagogical competence, and school culture on the quality of education at SMP Negeri Sub Rayon 01. Jepara Regency. This study was conducted at SMP Negeri in Sub Rayon 01. Jepara Regency, over three months, from October to December 2024. This location was selected based on the school's characteristics that are relevant to the research objectives. The researcher used a descriptive correlational research design, which aims to identify the relationships between the research variables: managerial competence of school principals (X. , pedagogical competence of teachers (X. , school culture (X. , and the quality of education (Y), as shown in the research design The population in this study consists of all active teachers at SMP Negeri in Sub Rayon 01.

Cronbach's Alpha coefficient was used to measure reliability, with the instrument being considered reliable if the Alpha value is greater than Data analysis was performed using descriptive and inferential statistical techniques, with simple and multiple regression tests to examine hypotheses about the influence of independent variables on the dependent variable. Before regression analysis, classical assumption tests were conducted, including normality, linearity, multicollinearity, and heteroscedasticity tests, to ensure that the data met the requirements for regression analysis. Results and Discussions In this study, respondents' perceptions of the variables under investigation include the managerial competence of school principals, teachers' pedagogical competence, school culture, and educational Data were obtained through a questionnaire using a Likert scale, which consists of five categories: strongly disagree (SD), disagree (D), agree to some extent (AS), agree (A), and strongly agree (SA). The respondents were 168 teachers from public junior high schools in Sub Rayon 01. Jepara District. The analysis results show that most respondents rated the educational quality variable as being in the relatively high category, with an average score of 83. 92 and a highest score of 105. The average score for the managerial competence of school principals was 132. 49, and most respondents rated the competence as ranging from low to reasonably high. Teachers' pedagogical competence had an average score of 120. 21, with most respondents falling into the relatively high category. Meanwhile, for school culture, most respondents rated it as being in the relatively high category, with an average score of 78.

Correlation testing was conducted to determine the relationship between the managerial competence of school principals (X. and educational quality (Y). The Pearson correlation coefficient was 0. with a significance of 0. < 0. This indicates a strong positive relationship between the managerial competence of school principals and educational quality. The F-test (ANOVA) used to examine the significance of the regression model showed an F-value of 5. 414 with a significance of 0. < 0. This means that hypothesis 1 is accepted, indicating that the managerial competence of school principals significantly affects educational quality. The coefficient of determination (RA) showed that 64. 2% of the variation in educational quality can be explained by the managerial competence of school principals (RA = The regression test results show that the regression coefficient for the managerial competence of school principals is 0. 636 with a tvalue of 6. 643 and a significance of 0. < 0. Based on these results, it can be concluded that the better the managerial competence of school principals, the higher the educational quality in public junior high schools in Sub Rayon 01. Jepara District. The correlation test between the pedagogical competence of teachers (X. and educational quality (Y) showed a Pearson correlation coefficient of 0. 676 with a significance of 0. < 0. , indicating a strong positive relationship between the two. The F-test (ANOVA) showed an F-value of 5. 952 with a significance of 0. < 0. , which means hypothesis 2 is accepted. These results show that the pedagogical competence of teachers has a significant effect on educational quality. The coefficient of determination (RA) indicated that teachers' pedagogical competence contributed 66. 2% to the changes in educational quality (RA = 0. The regression test showed a coefficient 661 with a t-value of 6. 976 and a significance of 0. < 0. This indicates that improving teachers' pedagogical competence can enhance educational quality in Sub Rayon 01. Jepara District public junior high schools. The correlation test between school culture (X. and educational quality (Y) showed a Pearson correlation coefficient of 0. 418 with a significance of 0. < 0. This indicates a positive relationship between school culture and educational quality. The F-test (ANOVA) with an F-value of 6. 054 and a significance of 0. < 0. supports hypothesis 3, showing that school culture has a significant effect on 142 | AJIS : Academic Journal of Islamic Studies, vol. 10, no. educational quality. The coefficient of determination (RA) indicated that school culture contributed 52. 1% to the changes in educational quality (RA = 0. The regression test with a coefficient of 0. 418 shows that every increase in school culture positively impacts educational quality, with a t-value of 6. 232 and a significance of 0. < 0. Multiple regression analysis was conducted to examine the simultaneous effect of the three independent variables on educational The F-test showed an F-value of 10. 395 with a significance of 047 . < 0. , indicating that these three variables significantly affect educational quality simultaneously. The coefficient of determination (RA) for this multiple regression model was 0. 627, suggesting that these three independent variables can explain 62. 7% of the variation in educational The regression results showed that the regression coefficients for the managerial competence of school principals were 0. 625, for the pedagogical competence of teachers 0. 655, and for school culture 0. all indicating a positive impact on educational quality. These results show that the three variables, namely the managerial competence of school principals, the pedagogical competence of teachers, and school culture, significantly impact educational quality in public junior high schools in Sub Rayon 01. Jepara District. Based on the descriptive analysis results, the managerial competence of school principals showed an average score of 132. 49 with moderate variation, indicating differences in perceptions of the managerial competence of school principals in public junior high schools in Sub Rayon 01. Jepara District. This finding suggests that although most school principals have fairly good managerial competence, there is much to be improved, particularly in supervision, which contributes the least to the dimension analysis. This is consistent with research conducted by Mulyasa32, who stated that the managerial competence of school principals significantly affects the effectiveness of school management and decision-making, directly impacting educational quality. Research by Gunawan and Gunawan33 also showed that inadequate supervision by school principals can reduce control over policy implementation and affect educational quality. Therefore, more intensive leadership and supervision training is needed to improve the competence of school 32 Mulyasa. Manajemen Pendidikan: Teori dan Praktik.

Findings related to teachers' pedagogical competence show that most teachers have fairly good pedagogical competence, although some have relatively low competence. This can affect teaching effectiveness, as suboptimal pedagogical competence will impact the quality of interaction between teachers and students. Based on the dimension analysis, the teaching implementation dimension contributed the most to teachers' pedagogical competence, indicating that teachers are more skilled in carrying out the teaching process than in planning and evaluating lessons. This is consistent with the findings of Ramayulis35, who revealed that pedagogical competence focuses on a teacherAos ability to design and manage effective learning. Hypothesis testing shows that teachers' pedagogical competence significantly affects educational quality, with a strong positive correlation . = 0. 676, p = 0. This finding aligns with research by Kosim36, which shows that teachersAo pedagogical competence significantly contributes to the quality of teaching and students' learning outcomes. Therefore, strengthening teachersAo pedagogical competence is crucial in improving educational quality in schools. School culture plays a significant role in creating an environment that supports effective learning. The research findings show that most respondents rated school culture fairly good, but some schools still had weaker cultures. The discipline dimension dominated school culture in public junior high schools in Sub Rayon 01. Jepara District, indicating that discipline is the most critical aspect in creating a conducive school This finding aligns with research by Lomos et al. who revealed that school cultures that support learning and positive Sari. , and A.

Hypothesis testing shows that school culture significantly affects educational quality, with a moderate correlation . = 0. 418, p = 0. A strong school culture, such as discipline, hard work, and responsibility, can enhance the overall quality of education. As Supriyanto38 stated, a conducive school culture supports character-building in students and enhances their motivation to learn. Therefore, strengthening school culture through training and applying positive values should be a priority in improving educational quality. The results of multiple regression analysis show that the three independent variablesAimanagerial competence of school principals, pedagogical competence of teachers, and school cultureAisimultaneously significantly impact educational quality. The F-test showed that the regression model has high significance . = 0. , meaning these three variables significantly improve educational quality. The coefficient of determination (RA = 0. indicates that these three variables can 7% of the variation in educational quality. Among the three variables, teachers' pedagogical competence significantly impacts educational quality, followed by the managerial competence of school principals and school culture. These findings support research by Suryana39, which shows that the managerial competence of school principals and teachers' pedagogical competence significantly affect educational quality. Therefore, improving educational quality must simultaneously strengthen the competence of school principals, teachers, and culture. Research by Sari and Kurniawan40 also affirms that the managerial competence of school principals, the pedagogical competence of teachers, and school culture simultaneously affect educational quality in schools. This indicates that a comprehensive approach is needed to create a quality educational environment. Conclusion Based on the analysis and discussion results, it can be concluded that the managerial competence of school principals, the pedagogical 38 Supriyanto.

Finally, simultaneously, all three variablesAithe managerial competence of school principals, the pedagogical competence of teachers, and school cultureAisignificantly impact the quality of education, with a contribution of 62. This shows that improving the quality of education requires a comprehensive approach that strengthens all three factors simultaneously. This study reveals that achieving optimal educational quality at public junior high schools in Sub Rayon 01. Jepara District, requires effective management of school principals' managerial competence, teachers' pedagogical competence, and school culture. All three elements must be strengthened through training programs and supporting policies to create a conducive and high-quality educational environment. References
