There are various types of character education that can be provided to students from an early age, one of which is mutual cooperation (Khasanah, et al. , 2. According to the results of the analysis, mutual cooperation is a cultural heritage that is known to strengthen the unity of the Indonesian nation and the formation of social identity (Anbiya, et al. , 2. However, with the development of the world, the values of mutual cooperation have begun to disappear, especially among the younger generation (Funsika, et al. , 2. Individualistic lifestyles and the influence of technology pose a challenge in fostering a spirit of togetherness (Siregar, et al. , 2. Therefore, concrete efforts are needed to revive these noble values (Ramadhan, et al. , 2. The phenomenon occurring in several schools shows that strengthening the character of mutual cooperation can be done through various effective activities, such as clean Friday activities (Atmaja, 2. Clean Friday is an activity that involves the entire school community in supporting and maintaining a clean environment together (Tasya, et al. , 2. The purpose of the clean Friday activity is to serve as a means of teaching social values and creating a healthy and clean environment (Khamala & Andriyani, 2. Based on the clean Friday activity, it will indirectly shape attitudes of caring, responsibility, and cooperation towards others (Syaiban & Sugiarti, 2. This activity also creates positive habits and builds a sense of belonging to the surrounding environment (Maela, et al. , 2. Children involved in this activity are trained to help each other, appreciate the roles of others, and work in teams (Kanza, et al. , 2. This is in line with the objectives of character education, which emphasizes the formation of positive attitudes and behaviors (Hanifah & Bakar, 2. Furthermore, social relationships among school members, such as the school community, school staff, and teacher involvement, can be supported and strengthened through Clean Friday activities (Harianto, et al. , 2. According to a literature study, simple or small changes can be implemented through Clean Friday activities (Riany, et al. , 2. In addition, strengthening the character of mutual cooperation can be done through direct practice in the field and not only based on theory (Atmaja, 2. Through this. Clean Friday activities can be used as a forum for creating and fostering a character of mutual cooperation among students (Lala, 2. Clean Friday can also be used as an environmentally friendly activity and realize a healthy school (Komalasari, 2. Through a collaborative approach, this activity strengthens the culture of cooperation in the educational community (Tani & Safikri, 2. In the long term, students who are accustomed to mutual cooperation will grow into individuals who care about their environment (Indrianingrum, et al. , 2. They will not only be academically smart, but also have high social sensitivity (Wijaya, 2. The implementation of a structured and consistent Clean Friday program can also serve as a model for character-based education (Silbia & Tirtoni, 2. Structured clean Friday activities can be used as a program in educational institutions such as schools (Tobing, et al. , 2. The active participation of the This article is licensed under CC BY-SA 4. 0 License entire school community can support the implementation of a sustainable and meaningful clean Friday program (Rahmadayanti, 2. Previous research by Mulyani, et. explains that mutual cooperation is a collaborative activity carried out to achieve certain goals and is carried out by many individuals or groups. According to the results of the analysis, character education needs to be instilled from an early The form of mutual cooperation behavior that is implemented aims to build awareness of the environment. In the clean Friday activity, the character that is indirectly instilled is mutual This can be seen through collaborative activities to clean the classroom, schoolyard, and school at the same time. The presentation also included the results of interviews in which students took turns extending and lifting chain pavers, cleaning the school garden, and cleaning the bathrooms during the Friday cleaning activity, thereby instilling character in the school environment. The Friday cleaning activity , which is carried out every Friday, aims to prevent disease and maintain school hygiene. The research gap is that there has not been much study on how teachers' strategies, the role of schools, and concrete activities can be used to implement the value of mutual cooperation in a planned and sustainable manner through Clean Friday activities. In addition, there is still little research examining the strengthening of mutual cooperation character through routine school activities in specific contexts . , specific education levels or school environment. , so the research results do not fully describe actual practices in the field. Based on these gaps, this study focuses on the habit of Clean Friday activities as a medium for implementing the strengthening of mutual cooperation character, by examining the process, strategies, and roles of the entire school community in instilling mutual cooperation values in students. Similarities with previous studies can be seen in that Clean Friday activities are effective in improving school environmental hygiene and fostering discipline and responsibility among Other studies also confirm that strengthening the character of mutual cooperation is one of the main values in Character Education that plays an important role in building social attitudes, cooperation, and concern among students.

Discussion Clean Friday is an activity that involves the entire school community in supporting and maintaining a clean environment together (Tasya, et al. , 2. The purpose of the Clean Friday activity is to serve as a means of teaching social values and creating a healthy and clean environment (Khamala & Andriyani, 2.

The role of teachers in the Friday cleaning activity is to monitor the activities carried out by students so that the work is focused and fosters a spirit of The Friday cleaning activity carried out at the school is not only done by one class, but by all classes or the entire school (Ramadani & Al Hamdany, 2.

The form of mutual cooperation behavior that is implemented aims to build awareness of the environment. In the Friday cleaning activity, the character that is indirectly instilled is mutual cooperation. This can be seen through collaborative activities to clean classrooms, schoolyards, and schools at the same time. The presentation also included the results of interviews in which students took turns extending and lifting chain pavers, cleaning the school garden, and cleaning the bathrooms during the Friday cleaning activity, thereby instilling character in the school environment. The Clean Friday activity, which is carried out every Friday, aims to prevent diseases in the school environment and maintain school cleanliness (Mulyani, et. , 2.

Teachers can also set an example for students in carrying out Friday cleaning activities, such as caring for and maintaining plants in the school environment, participating in cleaning the school environment, and so on.

Clean Friday activities carried out in almost all schools aim to shape students' character, particularly in strengthening the character of mutual cooperation. The following are the positive impacts of Clean Friday activities in strengthening the character of mutual cooperation: Fostering a sense of pride in the environment Students feel a sense of pride when they care for and maintain their school. Creating a comfortable and healthy school environment School cleanliness is a factor that influences the comfort of learning. Reducing individualistic tendencies The existence of clean Friday activities can reduce selfish attitudes and encourage an attitude of appreciating group work.

Conclusion In conclusion, mutual cooperation is a collaborative activity carried out to achieve specific goals and is performed by many individuals or groups. The clean Friday activity carried out in almost all schools aims to shape students' character, particularly in strengthening the character of mutual cooperation. The clean Friday culture implemented at the elementary school level can be carried out in various ways, including cleaning the school grounds, disposing of trash in its proper place, providing clean bathrooms, providing hand washing facilities, and providing trash disposal areas. Through these routine activities, character traits such as caring for the surrounding environment can be indirectly formed. Based on this, it can be seen that the activities carried out during clean Friday are not limited to cleaning activities alone. They can also foster and strengthen the character of mutual cooperation. Based on the above findings, the theoretical implications of this study can be summarized as follows: it contributes to the development of character education studies, particularly mutual cooperation in the context of school activities. This research enriches the theoretical basis of the concept of habituation as an effective strategy in instilling character values through routine activities, such as Clean Friday activities. In addition, this research reinforces the relevance of character education reinforcement theory, which emphasizes the integration of character values into school culture, not only through classroom learning but also through collaborative and contextual non-academic activities. Furthermore, this study has implications for increasing the collective awareness of the school community regarding the importance of cleanliness and environmental sustainability. Habituation to Clean Friday activities based on the value of mutual cooperation can foster a culture of environmental awareness and strengthen social relationships among the school community, thereby creating a healthy, harmonious, and conducive school climate. The suggestion is made to the author to continue this writing by adding several findings obtained from field observations or case studies, so that the research results are updated. This is because this writing is only based on library research. Furthermore, recommendations are also made to students, teachers, and other school members to create a culture of clean Fridays. This aims to shape the mutual cooperation character of students in its implementation. Recommendations are also addressed to readers and the wider community to study this topic in depth, so that the knowledge and information obtained is more extensive.
