This study is motivated by the phenomenon of moral degradation and the crisis of integrity in the digital era, as well as the sociological challenges faced by Pondok Pesantren Nurul Iman, which develops within a pragmatic and materialistic market environment. This condition necessitates a systematic and sustainable character education strategy, particularly in instilling the value of honesty among students. The study aims to describe the model of internalizing honesty values through the Weekly Majelis Taklim as the primary instrument for character building among students.This research employs a qualitative approach with a case study design. Data were collected through in-depth interviews, participatory observation, and documentation studies relevant to student development activities. Data analysis applies the interactive model of Miles and Huberman, which includes data collection, data reduction, data display in descriptive narrative form, and continuous conclusion drawing.The findings reveal that the internalization process of honesty is carried out systematically through the concept of the “Integrity Chain,” which consists of three main stages: (1) value transformation through the study of six authoritative classical Islamic texts (turath) to build a strong theological foundation; (2) value transaction through interactive dialogue, habituation, and exemplary conduct (uswah hasanah) of the teachers; and (3) value transinternalization reinforced by dormitory supervisors (musyrif) to foster inner awareness (muraqabah).Significant impacts are observed in students’ real behavior, such as honesty in canteen transactions, discipline in fulfilling responsibilities, and integrity in daily social interactions. This study concludes that the synergy between classical literature, collective role modeling, continuous habituation, and consistent environmental control is effective in building a “moral fortress” for students amid marginal environmental challenges and the currents of globalization.
