August 2025 INTRODUCTION Education plays a crucial role in the development of a nation, and one of the indicators of educational success is teacher performance. High-performing teachers can provide quality education, which in turn can enhance student achievement (Darsiah, 2023. Werang et al. , 2. In Kepulauan Meranti Regency, which consists of several small islands with limited accessibility, optimizing teacher performance presents unique challenges (Zulfikri, 2. These geographical challenges add complexity to school management and influence the organizational culture in local schools (Muhammad Adil & Fajarwaty Kusumawardhani, 2. This phenomenon underscores the importance of researching factors that can affect teacher performance in remote areas (Erna Lestari Rambe & Dedi Nofrizal, 2. In the context of education, effective school management and a positive organizational culture have been identified as key factors influencing teacher performance (Hasrul Azwar Hasibuan & Rindi Andika, 2023. Safitri & Nugroho, 2. Good school management encompasses various aspects such as leadership, resource management, and professional development for teachers (Nia Wardhani, 2022. Zahiq, 2. Pant . found that effective leadership, which emphasizes teacher professional development, significantly impacts teacher performance and student learning outcomes. Additionally. Susisanti . showed that transparent and accountable school management can increase teacher motivation and Organizational culture, on the other hand, refers to the values, norms, and practices embraced by the entire school community. Suhardi . stated that a strong organizational culture can create a supportive and productive working environment for teachers. Abduraimi et . asserted that a positive organizational culture can enhance teacher engagement and job satisfaction, which in turn improves their performance. An inclusive and collaborative organizational culture can also foster innovation and continuous improvement in schools (Ghedin. Although much research has been conducted on school management and organizational culture, most studies focus on urban schools with better resources. For instance, research by Virgana & Suradika . primarily explores schools in major cities with different conditions compared to remote areas like Kepulauan Meranti. This research gap highlights the need for a more in-depth study on the impact of school management and organizational culture on teacher performance in remote areas (Riski & Rino, 2. The research method used in this study is a quantitative approach with a survey method. Data were collected through questionnaires distributed to civil servant teachers in 41 junior high schools in Kepulauan Meranti Regency. The total number of teachers sampled was 135. Data analysis was performed using multiple regression techniques to test the relationship between the independent variables . chool management and organizational cultur. and the dependent variable . eacher performanc. This approach allows researchers to identify key factors that can enhance teacher performance in remote areas and provide strong empirical evidence on the influence of school management and organizational culture. The novelty of this research lies in its focus on remote areas, which have rarely been the subject of previous studies. Additionally, this study comprehensively combines the analysis of school management and organizational culture, which has not been extensively done in the context of education in Indonesia. Thus, this research not only provides significant theoretical contributions but also offers practical insights for school managers and education policymakers in remote areas. The objectives of this study are to analyze the impact of school management and organizational culture on teacher performance in Kepulauan Meranti Regency. Specifically, this study aims to identify the influence of school management on teacher performance, identify the influence of organizational culture on teacher performance, and explore the combined effect of school management and organizational culture on teacher performance ((Riski & Rino, 2. BRILIANT: Jurnal Riset dan Konseptual Volume 10 Number 3. August 2025 This research has several important uses. Theoretically, it contributes to the literature on school management and organizational culture in the context of education in remote areas. The findings can enrich the understanding of factors influencing teacher performance in regions with unique geographical and social characteristics. Practically, the findings have significant implications for school managers and education policymakers. Enhancing effective school management and building a positive organizational culture can be effective strategies to improve teacher performance in remote areas. Schools can organize training and activities involving the entire school community to achieve these goals. Recent literature also shows that the combination of effective school management and strong organizational culture can yield more optimal results in improving teacher performance. Louis & Murphy . found that the combination of strong leadership, positive organizational culture, and active community participation can create a dynamic and productive school Additionally, research by McLean . found that schools involving the entire school community in planning and implementing school programs tend to be more successful in achieving their educational goals. Thus, a holistic approach involving all stakeholders in the education process is crucial to enhancing teacher performance. To gain a deeper understanding of the impact of school management and organizational culture on teacher performance, this study also reviews recent and relevant literature from reputable journals. For instance, a study by Al Shebli . showed that effective leadership and strong organizational culture can drive innovation and continuous improvement in schools. Meanwhile, research by Kinay Kuru & Tabancali . found that leadership focusing on learning and teacher professional development can significantly impact student achievement. Research by Gouydard et al. demonstrated that a positive organizational culture can enhance teacher well-being and job satisfaction, which are important factors in creating an effective learning environment. Overall, this research aims to provide a comprehensive overview of the impact of school management and organizational culture on teacher performance in Kepulauan Meranti Regency. By focusing on remote areas, this study offers a new perspective that is important for improving the quality of education in Indonesia. This research is also expected to serve as a reference for future studies in the field of educational management and human resource development. The findings are anticipated to provide practical insights that can be applied by school managers and education policymakers to enhance teacher performance and the quality of education in remote Through a holistic approach involving all stakeholders in the education process, it is hoped that the effectiveness of schools in Kepulauan Meranti Regency can be enhanced, resulting in high-quality and competitive graduates. METHOD Research Design This study employs a correlational research design, aimed at predicting the effect of the relationship between two variables. In this design, the score on one variable can be predicted if the score on another variable is known (Fraenkel et al. , 2. The study examines the influence of school management and organizational culture on teacher performance. The focus is on exploring the dependency of the dependent variable on one or more independent variables and predicting the mean population or average value of the dependent variable based on known independent variables. Sample and Data Collection In research, the sample is representative and serves as respondents or subjects for the Responsible sampling is crucial for obtaining accurate data and ensuring reliable The sample for this study consists of 143 junior high school teachers in Kabupaten Kepulauan Meranti . 79 female. The sampling technique used is simple random 550 BRILIANT: Jurnal Riset dan Konseptual Volume 10 Number 3. August 2025 sampling, where sample members are selected purely by chance, ensuring each member has an equal opportunity to be included in the sample (Bhardwaj, 2. To obtain precise and accurate data for addressing the research issues, a questionnaire was used for data collection. For the school management variable, the study adopts the concept from Nishimura . , which includes key foundational concepts for effective educational These concepts include school-based management (SBM), focusing on principles that enhance student learning outcomes and the implementation of inclusive and equitable education. Additionally, educational management involves aspects such as leadership principles, strategic planning, human resource management, curriculum management, and external relations, all crucial for ensuring quality education and continuous improvement in learning outcomes (Fernow, 2. Based on this concept, the study formulated 12 statement items, including AuThe principal guides teachers who have not completed teaching supervision. Ay For the organizational culture variable, the study adopts the concept from Kava et al. and Scammon et al. , where organizational culture consists of the beliefs and expectations upheld by organizational members. Organizational culture includes norms, values, and general beliefs of individuals within the group. Based on this concept, the study formulated seven statement items, including AuI clearly understand the vision and mission of the school, so I pay attention to every detail of my work. Ay For the teacher performance variable, the study adopts the concept from Listyo Prabowo . , which refers to the teacher's ability to focus on the learning process and be responsible for the students under their supervision by enhancing student Therefore, the study formulated 11 statement items, including AuDescribing the stages of material that students have mastered. Ay The questionnaire was distributed to respondents using Google Forms, and participants responded using a five-point Likert scale (Always-Neve. Data Analysis All testing processes were conducted using Microsoft Excel and Smart-PLS version The study began with descriptive analysis, validity testing, reliability testing, multiple linear regression analysis, and significance testing. Descriptive analysis was used to determine the characteristics and responses of respondents to the questionnaire items (Pio & Lengkong.

In the descriptive analysis, only the items that meet validity and reliability parameters are presented, so not all items from the initial construct are described. The results of the descriptive analysis for the school management variable reveal that respondents generally provided positive feedback on the statement items. Item 10 received the lowest mean score compared to other items, indicating that respondents felt the principal had not sufficiently guided teachers who had not completed their teaching supervision. In contrast. Item 11 received the highest positive response, where respondents felt that the principal provided BRILIANT: Jurnal Riset dan Konseptual Volume 10 Number 3. August 2025 guidance on lesson plan development. These findings suggest that efforts by the principal to improve teacher performance need further development. When teachers have not completed their supervision, the principal should seek solutions and guidance until the teachers meet the performance criteria effectively. It is important to note that providing solutions should not be limited to the initial lesson planning phase but should include ongoing supervision throughout the teaching semester. Table 1.

Item 2 received the lowest mean score among the items. however, respondents did not assign a score of 1. 00, indicating that at the lowest, teachers "sometimes" pay attention to every detail of their work as evidence of their understanding of the school's vision and mission. The item with the highest mean was, "I am responsible for the tasks assigned to me, and I will perform them according to the established procedures to achieve the school's goals. " This suggests that the organizational culture related to achieving school goals is "frequently" upheld well by teachers. Overall, the mean scores for each item ranged from 4. 30 on a five-point Likert scale . ee Table . , leading to the conclusion that the respondents' perceptions of organizational culture are classified as "good.

AVE Inner Model Testing The collinearity statistics (VIF) test results indicate that the collinearity for the relationship between school management and teacher performance is 1. 857, and for the relationship between organizational culture and teacher performance is also 1. These results suggest that the research variables meet the VIF criteria, as the values are <10. According to classical linear regression assumptions, a good regression model is one that is free from Thus, the model is free from multicollinearity (Leityo et al. , 2. Further examination of the inner model revealed a coefficient of determination (R-squar. 518 and an adjusted R-square value of 0. 511, placing it in the moderate category (Amali et , 2022. Hair et al. , 2011. Sarwono, 2. An R-square of 0. 511 indicates that all independent variables collectively account for 51. 1% of the variation in the dependent variable, meaning that 9% of the variance is influenced by other variables not tested in this study. The Root Mean Square Residual (SRMR) is defined as the difference between the observed correlations and the model-implied correlation matrix. It allows for the assessment of the average discrepancy between observed and expected correlations as an absolute measure of model fit (Henseler et al. , 2. The SRMR test results show that the saturated model has an SRMR value of 0. 072, which is <0. ee Table . , indicating that the model meets the Goodness of Fit (GoF) criteria. Table 6.

Figure 1. the inner model analysis using path coefficients and T-values Discussion The results of this study indicate that school management and organizational culture have a significant impact on teacher performance in the Kepulauan Meranti Regency. The collinearity statistics test (VIF) shows that both independent variables, school management and organizational culture, have a VIF value of 1. This value is below the threshold of 10, indicating that there is no issue of multicollinearity in the regression model used (Leityo et al. , 2. Thus, the linear regression model employed in this study is considered free from multicollinearity, meeting an essential classical assumption for the validity of the results. Further testing of the inner model reveals an R-square value of 0. 518 and an adjusted Rsquare value of 0. This adjusted R-square value indicates that 51. 1% of the variability in teacher performance can be explained by the variables of school management and organizational culture simultaneously, while the remaining 48. 9% is influenced by other variables not included in this study (Amali et al. , 2022. Hair et al. , 2011. Sarwono, 2. The moderate category of the adjusted R-square value suggests that the research model has a reasonably good capability to explain the relationship between the independent and dependent variables. Furthermore, the Root Mean Square Residual (SRMR) test results show a value of 0. which is below the threshold of 0. 10 (Henseler et al. , 2. SRMR is used to measure the average difference between the observed correlations and the correlation matrix implied by the model. low SRMR value indicates that the model fits well, meaning that the model used in this study is considered appropriate and accurate in representing the existing data. These findings suggest that both effective school management and positive organizational culture play crucial roles in improving teacher performance. Effective school management, which includes strategic planning, human resource development, financial management, and operational supervision, has been shown to enhance teacher motivation and performance. Inspirational and participatory school leadership also contributes to increased teacher morale and dedication in performing their duties (Zega et al. , 2. A positive organizational culture is also found to have a significant impact on teacher A supportive and collaborative culture creates a conducive work environment, which in turn enhances teacher satisfaction and work commitment (Kurt & Duyar, 2. Active participation from all school members in decision-making processes also proves to increase the sense of ownership and responsibility towards overall school performance (Kaltsas & Gkaintartzi. BRILIANT: Jurnal Riset dan Konseptual Volume 10 Number 3. August 2025 The findings of this study are consistent with previous research indicating that a combination of good school management and positive organizational culture can lead to optimal teacher performance. This study provides an important contribution to the literature on educational management, particularly in the context of remote areas such as Kepulauan Meranti Regency, where challenges in school management and organizational culture development may be more complex compared to urban areas. In practice, these findings offer insights for school administrators and education policymakers to continue developing effective management strategies and fostering a positive organizational culture. Through these efforts, it is hoped that teacher performance can be continuously improved, ultimately leading to a positive impact on the quality of education in Kepulauan Meranti Regency. CONCLUSION The findings of this study demonstrate that school management and organizational culture have a significant impact on teacher performance in Kepulauan Meranti Regency. Based on the collinearity statistics test (VIF), the VIF value of 1. 857 for both school management and organizational culture variables indicates that the model is free from multicollinearity issues. Inner model testing resulted in an R-square value of 0. 518 and an adjusted R-square value of 511, indicating that 51. 1% of the variability in teacher performance can be explained simultaneously by the variables of school management and organizational culture, while the 9% is influenced by other variables not tested in this study. Additionally, the Root Mean Square Residual (SRMR) test results show a value of 0. which is below the threshold of 0. 10, indicating that the model used in this study has a good fit and accurately represents the data. Overall, this study underscores the importance of effective school management and a positive organizational culture in enhancing teacher performance, which can ultimately lead to improvements in educational quality. The recommendation from this research is First. Development of School Management Competencies: School leaders and education managers should receive ongoing training and development to enhance their competencies in school management. This training should include aspects of strategic planning, human resource development, financial management, and operational supervision. Second. Improvement of Organizational Culture: Schools should foster a supportive and collaborative organizational culture. This can be achieved through programs that promote team cooperation, effective communication, and active participation of all school members in decision-making Third. Utilization of Technology for Management: Implementing information technology in school management can improve operational efficiency and effectiveness. Technology-based school management systems can assist in data management, communication, and decisionmaking processes. Fourth. Enhancement of Community Participation: School leaders should develop strategies to involve more staff, students, and the school community in decision-making Broader participation can enhance commitment and job satisfaction, ultimately improving teacher performance and school quality. Last. Continuous Evaluation and Monitoring: Schools should conduct regular evaluations and monitoring of management performance and organizational culture. This can help identify areas needing improvement and ensure that implemented strategies are effective. REFERENCES
