This research aims to determine the effect of the inquiry learning model on student learning outcomes in class IV Mathematics at SD Negeri 22 Sigaol Marbun for the 2023/2024 academic year. The research method used is an experimental method with a quantitative research type. To obtain the data required a test instrument of 25 questions. The total research sample was 31 students based on purposive sampling technique. To determine students' initial abilities, the research conducted a Pre Test with an average score of 56.77 which was included in the poor category. The results of the Post Test have improved from the Pre Test results given previously with the students' average score reaching 73.29 in the good category. It can be said that the level of success in student learning outcomes has increased as evidenced by the results of the correlation coefficient test calculation, which obtained r_count ≥r_tabel with results of 0.716 ≥ 0.355. Next, hypothesis testing compares the t_count ≥t_table value. The obtained value of t_count = 5.523 while t_table = 1.696. Because t_count ≥t_table (5.523 ≥ 1.696) then H_a is accepted and H_o is rejected. Through the t-test, it can be concluded that there is a significant positive influence between the Inquiry learning model (X) on student learning outcomes (Y).

The socialization sessions, characterized by a structured mix of material presentations (30%) and interactive discussions (70%), served as an educational platform for primary school students to understand the importance of maintaining a clean and health-conscious lifestyle. Subsequent field activities engaged participants in collaborative problem-solving efforts, primarily realized through synchronized cleaning initiatives in the school environment and the introduction of technologically advanced automated trash cans. In addition, the project incorporated technological innovation by introducing automated trash cans, which were strategically designed to capture the interest of the students and provide essential knowledge on proper waste disposal practices. The findings underscore the efficacy of a nuanced approach that combines educational efforts, practical efforts, and technological interventions in shaping sustainable behavior among the younger generation, thereby positively impacting the broader community environment.

This community activity attempts to enhance student discipline at the primary school level through a holistic strategy that engages kids, teachers, parents and the surrounding community. Starting with a successful opening seminar which introduced the concept of discipline as the main foundation in forming student character, this program continued with an interactive workshop which provided in-depth understanding and special training for teachers in integrating discipline habits into everyday learning. Involving parents and community people through discussion forums, this program enables successful collaboration between the school environment and the local community. Program evaluations reveal better understanding and good changes in student conduct. The closing seminar as the final event of the program provides an opportunity to present concrete outcomes, successful experiences and future visions. This community activity not only meets the goal of enhancing student discipline, but also fosters a communal commitment to maintain the culture of discipline that has been successfully developed. The outcomes not only have an influence at the school level, but also provide a successful model that may be replicated by other educational institutions in an effort to improve student discipline and the overall quality of basic education

Evaluation and reflection findings revealed that this activity was successful in providing positive changes in attitudes and understanding, with awards given at the end of the event as appreciation for the participants' commitment. By expressing the conclusions of this service, this abstract shows the success of the initial steps in improving literacy culture at Tanah Merah State Elementary School. This aims to ensure that the enthusiasm and understanding that emerges from this activity can become a catalyst for sustainable change at the school level and in the local community.

This community service aims to develop a culture of literacy at SD Negeri 034816 Jambu Mbellang through the habit of reading for 5 minutes. Involving instructors, students and parents, this program focuses on producing positive changes in reading behavior among participants. By carrying out preparatory analysis and planning, we explain the literacy situation in schools and propose relevant strategies. The results of implementing this program show a major change in children's enthusiasm for reading, as well as growth in literacy skills. Ongoing reviews and regular monitoring can identify supporting factors and barriers to program performance. Outreach to parents and their involvement in children's literacy instruction is critical in establishing a supportive atmosphere at home. Workshops and additional training for teachers and parents provide insight and practical solutions to improve literacy learning. The success of this program is not only seen in improving students' reading abilities, but also in changes in attitudes, active participation of parents, and growth in teacher skills. These results suggest that bringing the entire school community together can foster a positive and sustainable literacy culture. It is hoped that this success will provide inspiration and input for similar efforts to improve literacy in other schools.

The output of this service shows that the lecture session succeeded in increasing students' understanding of the world of entrepreneurship, while the practice of making small parcels provided direct experience in applying these concepts. The exhibition of student work reveals originality in selecting local materials, helping the local economy, and exploring creative potential in business procedures. Apart from having a good influence on children, strong collaboration between schools, teachers and the surrounding community has also been successful. The complete study shows that the success of this service has helped encourage students' enthusiasm to continue exploring their entrepreneurial potential. The results of this service show that a holistic approach through a combination of lectures and practice of making micro parcels has a good impact on students' understanding of entrepreneurship. However, to ensure sustainability and sustainable growth, follow-up action is needed in the form of building an entrepreneurship program that is integrated into the curriculum and forming small groups to encourage student interest. Thus, this abstract illustrates the effectiveness of this service in arousing curiosity and entrepreneurial creativity at SDN Kuala Geulumpang students, with the aim of being able to make a good contribution to the development of their character and talents in the future.
