Arabic language learning in madrasahs continues to face various challenges, particularly students’ limited communication skills and the lack of an optimal language environment (bi’ah lughawiyah) that supports the active use of Arabic. In addition, strengthening students’ leadership character requires more practical and participatory approaches. Therefore, the Mukhoyam Arabiy program was implemented as a medium for leadership development and as a platform for fostering a bi’ah lughawiyah among madrasah students. This program aimed to enhance students’ Arabic communication skills while simultaneously developing their leadership character through a Service Learning approach that integrates learning, service, and direct experience within an educational setting. The program was conducted from May 14–17, 2026, at MTsN 1 Bitung and involved 120 participants from Madrasah Ibtidaiyah (MI), Madrasah Tsanawiyah (MTs), and Madrasah Aliyah (MA) levels representing various educational institutions. The implementation employed a camping-based system featuring a range of activities, including muhadatsah (Arabic conversation practice), language games, leadership training, group discussions, Arabic language immersion, and collaborative assignments that encouraged active participation in both learning and service activities. The results indicated significant improvements in participants’ confidence in using Arabic as a communication tool, as well as enhanced teamwork, responsibility, and leadership skills. Furthermore, the program successfully fostered a more communicative and participatory bi’ah lughawiyah. The activities also contributed positively to the development of participants’ social skills through contextual and collaborative learning experiences. Therefore, Mukhoyam Arabiy can serve as an effective Service Learning-based model for madrasah student development, supporting the strengthening of language culture and the sustainable formation of leadership character.
