<![CDATA[The formation of Islamic character in students requires a systematic and structured approach within the school environment. At SMA Al-Hadiid Cileungsi, the habituation of 5S (Salam, Senyum, Sapa, Sopan, Santun/Greeting, Smile, Courtesy, Politeness, Manners) has been introduced; however, its implementation remains suboptimal due to a lack of instructional guidelines and a standardized monitoring system. This Student Creativity Program for Community Service (PKM-PM) was conducted from [August to October 2026] using the Participatory Action Research (PAR) approach, actively involving the entire school community. This program aims to optimize the students' Islamic culture through the development and implementation of a 5S-based Character Building Module. The implementation steps consist of five main phases: (1) partner needs analysis and coordination, (2) design and validation of the Character Building Module, (3) dissemination and training on module usage for teachers and students, (4) daily implementation mentoring, and (5) periodic evaluation. The developed module contains Islamic etiquette guides, 5S habituation scenarios, and a mutaba’ah yaumiyah sheet (daily control log). The results of the program demonstrate a significant increase in student participation and consistency in practicing 5S within the school environment. Furthermore, this module successfully established a measurable character monitoring mechanism for teachers and enhanced a friendly, noble-character school climate. This program serves as a sustainable, practical solution for strengthening the internalization of Islamic values in partner schools.]]>
