Received: May 20, 2025 Accepted: June 03, 2025 Published: June 07, 2025 ABSTRACT This research examines strategies for improving Organizational Citizenship Behavior (OCB) among teachers by strengthening Servant Leadership. Organizational Culture. Interpersonal Communication, and Perceived Organizational Support (POS). The study, conducted in a private high school in Depok. Indonesia, utilizes a quantitative approach and path analysis to evaluate the direct and indirect effects of these variables on OCB. The results show that Servant Leadership. Organizational Culture. Interpersonal Communication, and POS all have direct positive and significant effects on OCB. Additionally. POS acts as an effective intervening variable, enhancing the impact of Servant Leadership. Organizational Culture, and Interpersonal Communication on OCB. The research findings suggest that fostering these factors can significantly improve OCB, which in turn enhances organizational effectiveness and the overall educational environment. The SITOREM analysis further identifies key indicators that need strengthening to optimize the strategies for increasing OCB in educational settings. INTRODUCTION especially in determining the success of Global changes, technological students, especially in relation to the developments in various aspects teaching and learning process, because including the education area demand teachers are always related to any educational outputs that are able to component in the education system. meet the changing times. This condition Teachers have an important role as requires schools to be able to adapt to teachers and educators in the world of carry out learning management. Indonesian education who will shape and guide the nation's generation Innovation in schools can only be towards a better direction, where one of realized if teachers as the spearhead of the roles of teachers, especially high school teachers, is to prepare students to importance of their role as educators enter the next level of education, namely and learning motors. to the college level. Where in higher This makes teachers the most education innovativeness is needed so decisive component in the education that students are able to compete in the system as a whole, which must receive Based on the Law of the Republic central attention. Teachers play a major of Indonesia No. 14 of 2005 concerning role in educational development. Teachers and Lecturers, states that there Kontigensi: Jurnal Ilmiah Manajemen Management Science Doctoral Program. Pasundan University. Bandung.

No. June 2025, pp. ISSN 2088-4877 are a number of requirements to become a professional teaching staff, including having good communication skills, competence and professional education qualifications, having good morals, having a commitment and good work ethic towards their profession and being able to develop themselves. In this case, teachers are not only enough to do the job description, but must have extrarole behavior which is often called Organizational Citizenship Behavior (OCB). OCB can be defined as individual behavior that is free . , which is not directly and explicitly rewarded by the formal reward system, and which as a whole . increases the efficiency and Teachers who have OCB will be happy to help novice or unprofessional teachers in terms of the work faced The assistance provided can be in the form of guidance on good learning techniques, patterns of handling guidance to students or in the form of administration in terms of quality From guidance and coaching of fellow experienced and have OCB will increase the quality of teachers. SMA is an upper secondary education level that prioritizes the preparation of students to continue higher education where specialization in the form of majors starts in grade XI . , namely, majors in Natural Sciences (IPA). Social Sciences (IPS), and Language. However, based on the Decree of the Minister of Education. Culture. Research and Technology Number 56 / M / 2022 concerning Guidelines for Implementing the Curriculum in the Framework of Learning Recovery, it does not fully accommodate the interests, talents and abilities of students, as well as workload adjustments and structuring the linearity of certified teachers, so it needs to be changed. In order for students' talents, interests and abilities to develop properly, the idea of the Minister of Education and Culture (Mendikbu. Nadiem Anwar Makarim, namely the new policy program from the Ministry of Education and Culture "Merdeka Belajar". In Merdeka Belajar there is no more majoring. This means that the majors of science, social studies or language are abolished. Students are allowed to choose elective group subjects when they are in grades XI and XII. The selection of subject interests can adjust the talents and interests of each student guided by the Counseling Guidance (BK) teacher. Meanwhile, teachers are given the freedom to determine the teaching tools to be used, by adjusting the learning needs and interests of the students. In order to achieve certain goals, the quality of human resources (HR), namely teachers, needs to be improved in terms of quality and OCB behavior because teachers are a determining factor in the success of education Teachers as one of the human resources, become the mainstay in achieving school goals. Teachers play a significant role in the level of Disciplined and responsible teachers are needed to carry out all their roles and responsibilities, both individually and in teams so that learning runs In addition to the main duties and functions as educators, there are basically many extra behaviors that teachers need to do so as to support the Kontigensi: Jurnal Ilmiah Manajemen Management Science Doctoral Program.

Behavior that is not listed in the employee duties and obligations document, which does not directly bring material or non-material rewards but contributes significantly to the progress of the school. In the study of organizational behavior, this is known as Organizational Citizenship Behavior (OCB). OCB is voluntary behavior outside the formal job description and does not get rewarded but overall can increase effectiveness in the organization. Teachers who are willing to arrive earlier than the work schedule to prepare daily activity plans will make them more prepared to welcome and carry out learning activities while having more free time to anticipate the risks of obstacles in learning. Teachers who volunteer to spend more time updating learning materials by surfing for references have the potential to have richer and more up-to-date lesson plans so that contextual learning can be Teachers who are happy to help new teachers with the adjustment process, helping them adapt to the school culture, helping them learn the administrative formats of the school curriculum, will make new teachers feel more quickly adjusted to their roles and Teachers who volunteer to promote the school without being paid will help strengthen the school's positive image in the community and increase trust in the school. Teachers who volunteer to help colleagues who are struggling with their work, cover for colleagues who are absent or on break, help colleagues who are overloaded with work, help with other people's work when they are absent, will keep the overall task list accomplished. Teachers who exercise restraint and do not complain about limited school facilities will support a more conducive Teachers who guard their actions against potential conflicts will greatly help create a more comfortable work atmosphere and support the smooth achievement of work targets. OCB improves social interaction reduces disputes, and increases efficiency in doing work, hence the importance of increasing OCB in Members with high OCB will be more careful in using increasing efficiency. Members with high OCB tend to be retained by the volunteerism and extra effort for the progress of the organization, thus helping the organization improve its stability and ability to adapt to environmental changes. Based on the exposure of the OCB organizations, and especially the contribution of teacher OCB to school achievement, it is very important to increase OCB. Teachers with high OCB have the potential to contribute to improving student achievement and achieving school goals, because they utilize school resources more optimally for more productive purposes, and more eagerly participate in school Teachers' extra role behaviors improve the quality of human resources in schools, thus potentially improving services to students towards the success of national education goals. On the other hand, the facts in the field do not fully show the high level of OCB among teachers. Based on a preliminary study of 63 private high school teachers in Depok City, the following results were obtained: Kontigensi: Jurnal Ilmiah Manajemen Management Science Doctoral Program.

No. June 2025, pp. ISSN 2088-4877 32% of teachers still have problems in helping colleagues, especially in volunteering to help other teachers to complete their work and introducing the school environment to new 8% of teachers are still not tolerant of less-than-ideal conditions at school, as evidenced by a decrease in teaching enthusiasm when rewards are given late, and objections when using inadequate teaching facilities. 34% of teachers still have problems in activities more than personal activities, especially volunteerism that has not been seen in properly completing additional tasks outside of work time, and providing information on school activities at every MGMP meeting. There are 38% of teachers who have problems with responsibility, as seen in their reluctance and lack of enthusiasm to take on additional tasks from the principal, and willingness to submit work reports to the principal early. 19% of teachers had problems Some expressed reluctance to discuss with more experienced teachers in order to improve student achievement, and reluctance to admit mistakes and apologize to fellow teachers. The results of this initial study indicate that there is still a need to increase OCB among private high school teachers in Depok City so that schools avoid a less conducive work atmosphere where teachers do not help each other, learn from each other and are willing to voluntarily maintain behaviors that have the potential to cause conflict in schools. High OCB is needed so that teachers remain enthusiastic even though schools are not able to provide adequate infrastructure, this is necessary considering that private high schools in Depok City do not all have the ability to provide Reluctance to tolerate school limitations risks reducing the quality of learning Teachers who have not voluntarily taken action to create a peaceful atmosphere in the school have the potential to create a tense and less conducive work situation that will interfere with the smooth running of the Various studies on OCB are still being conducted to date which shows that OCB is still a concern of both practitioners and academics. Research on 30 employees and 10 managers of women's cooperatives concluded that there is a significant positive effect of culture and organizational commitment on OCB (Harwiki, 2. , this research examines OCB in companies. OCB research in public schools in Pakistan concluded that if OCB is present among teachers and principals, then productivity increases, therefore professional development of school principals' capacity is needed to encourage OCB (Ghaffar, 2.

There is a direct Interpersonal Communication on OCB, which means Interpersonal Communication can increase OCB: . There is a positive indirect effect of Job Satisfaction on OCB through the Transformational Leadership, but the strength of the effect through this mediation is lower than the direct effect of Transformational Leadership on OCB. This means that Transformational Leadership does not function effectively as an "intervening variable" mediating the effect of Job Satisfaction on OCB. Improving OCB is more effectively done directly through strengthening Job Satisfaction. There is a positive indirect effect of Job Satisfaction OCB Interpersonal Communication, but the strength of this mediation effect is lower than the direct effect of Interpersonal Communication on OCB.

This shows that job satisfaction is able to mediate POS on OCB at the agency. Research on OCB in private SMK employees shows that organizational culture, organizational justice, and organizational commitment have a positive and significant effect on OCB both partially and simultaneously. This positive and significant influence means organizational commitment run well or increase, employee OCB will also be good or increase and vice versa. These results will be useful for school management to foster employee OCB through a school culture that provides space for employees to take initiative, be creative, and take risks in their work to be able to develop new ideas or new strategies that lead to a sense of responsibility for the sustainability of Kontigensi: Jurnal Ilmiah Manajemen Management Science Doctoral Program.

METHOD This research uses a quantitative approach with a survey design that . descriptions of trends, behaviors, and opinions of small groups or samples from a population. Before research is conducted, it is necessary to develop a plan or proposal by outlining the involvement of elements of philosophy, research design and specific methods (Creswell Creswell. Quantitative research uses a positivist perspective by involving various theories, collecting data that supports or refutes the theory and then developing a new synthesis conceptually and applying the research operationally. The quantitative approach is applied in inferential research, namely in order to test hypotheses about the influence between variables. For this reason, it is necessary to determine a research design or theoretical model that describes the constellation between the dependent variable. Meanwhile, the method chosen in this research is the survey type. The survey method is an example of non-experimental research manipulation of independent variables is carried out as a condition that has been formed and is not the result of a special treatment (Johnson Christensen. Meanwhile, this research design is organized as follows: This research consists of quantitative survey research to prove the research Verify quantitative research results through SITOREM Analysis. RESULT Hypothesis Testing After analyzing the structural model, the results of the resulting calculations are used in hypothesis testing so that further direct and indirect effects of each variable are known.
