<![CDATA[Learning of Thaharah at MAN 1 Bandar Lampung has been dominated by one-way lecturing, and a preliminary survey indicated weak affective engagement among students. This study was therefore intended to design and validate an interactive, web-based learning medium capable of strengthening students' interest in the topic. Design/methodology/approach – A Research and Development (R&D) design guided by the ADDIE framework (Analysis, Design, Development, Implementation, Evaluation) was employed. The resulting product, an interactive website built on the Wix platform, consists of five sections — Home, Subject Matter, Quiz, About, and User Guide — and was evaluated by a content expert, a media expert, and a language expert. Field testing was carried out in two stages: an 8-student limited trial followed by a 30-student trial among Grade X IIK learners, with learning interest measured through a Likert-scale instrument covering desire, enjoyment, knowledge, habit, and attention. Findings – Expert evaluation rated the medium at 92.5% for content, a perfect 100% for media quality, and 97.5% for language, averaging 96.7% and earning a Very Feasible classification. Learning interest reached 4.29 (85.7%) in the limited trial and 4.16 (83.2%) in the field trial, both categorized as high; within the field trial, 46.7% of students fell into the very-high band and 50.0% into the high band. Research Implications – The findings indicate that an ADDIE-based interactive website can credibly replace lecture-centered delivery for procedural, practice-heavy content such as Thaharah. Beyond validating this particular product, the study offers teachers and madrasah leaders a template for extending web-based multimedia to other Fiqih topics, and points future researchers toward pairing affective gains with parallel measures of cognitive and psychomotor achievement.]]>
