Cadassari Village, Purwakarta Regency, has strong religious potential as reflected in the activities of Quranic Education Centers (TPQ) and community involvement in childrens religious development. Nevertheless, the quality of Quran memorization among elementary school children in this village still faces several challenges, particularly in terms of reading fluency, accuracy of verse sequence, and consistency of murojaah (revision). This condition motivated the implementation of a community service program focusing on strengthening the quality of childrens Quran memorization through a participatory approach. The program was carried out by actively involving TPQ teachers, parents, and the village community at every stage of the activities using the Participatory Action Research (PAR) approach. Over a five-week implementation period, the activities began with the classification of childrens memorization levels, followed by regular Quran murojaah mentoring conducted every evening after the Maghrib prayer, and concluded with the implementation of the Musabaqah Hifzhil Quran (MHQ) as an evaluation medium. The MHQ was conducted through verse continuation and the recitation of a selected surah to comprehensively assess the quality of childrens memorization. The implementation of the program demonstrated positive changes in the childrens ability to maintain their memorization, as indicated by improvements in reading fluency, accuracy in verse continuation, and self-confidence when performing in public. In addition to its impact on the development of childrens memorization, the program also increased parental involvement in murojaah mentoring and strengthened the Quranic culture within the Cadassari Village community.
