<![CDATA[This study aims to develop an Eduklan learning medium based on the Wix Website platform, integrated with the Project-Based Learning (PjBL) model, and to evaluate its feasibility in supporting fifth-grade elementary school students' advertising text writing skills. This study employed the Research and Development (R&D) method using the ADDIE development model, which consists of five stages: analysis, design, development, implementation, and evaluation. The study was conducted at SDN Sugihwaras 1, Magetan Regency, involving one media expert, one content and language expert, one fifth-grade teacher, and 13 fifth-grade students. The research instruments included observation sheets, interview guidelines, expert validation questionnaires, teacher and student response questionnaires, project assessment sheets, and individual evaluation tests. Data were collected through observations, interviews, questionnaires, documentation, project assessments, and learning outcome evaluations. The data were analyzed using descriptive quantitative techniques based on a four-point Likert scale, with the results converted into percentages. The findings showed that the content and language expert validation achieved 96.25%, the media expert validation reached 95.31%, teacher responses scored 92.19%, and student responses reached 92.56%, all of which were categorized as "very good." Furthermore, the average score of the individual evaluations was 83.08, while the project assessment results ranged from the "good" to the "very good" category. These findings indicate that the Eduklan learning medium based on the Wix Website platform and integrated with the Project-Based Learning (PjBL) model is highly feasible, practical, and suitable for supporting the teaching of advertising text writing to fifth-grade elementary school students.]]>
