This study examines the implementation of muhadatsah (Arabic conversation) learning using YouTube media at Pondok Pesantren Tazakka, Pasar Surulangun, North Musi Rawas. This qualitative research employs a case study approach with data collected through in-depth interviews, classroom observation, and documentation. Informants consisted of three Arabic language teachers and six santri. The findings reveal three key outcomes: (1) muhadatsah learning using YouTube is conducted in a structured three-stage framework comprising pre-watching, while-watching, and post-watching activities, with teachers selecting fushah Arabic videos of short duration supplemented with Arabic subtitles, followed by guided imitation and paired speaking practice; (2) supporting factors include authentic language input, multimodal visual elements, YouTube technical features such as subtitle and playback speed control, and increased santri motivation, while inhibiting factors include fast native speaker pace, idiom complexity, differing ability levels, unstable internet connection, limited time, and distraction risk; (3) santri responses are predominantly positive, showing increased speaking confidence, vocabulary development, improved pronunciation and intonation, with critical suggestions for more intensive speaking practice and better-leveled video selection. This study concludes that YouTube is effective as a pedagogical support medium for muhadatsah learning when integrated systematically with teacher guidance and structured speaking activities.
