<![CDATA[Motivating this research was the fact that SMK Negeri 3 Pekanbaru's Grade XI Fashion Design students were having a hard time with things like precisely measuring themselves, analysing the components of the Kebaya Labuh, and understanding the stages involved in making patterns. Printed work sheets were also the only form of instructional media used before, and they were severely lacking in detail especially when it came to dissecting the Kebaya Labuh's constituent parts and in their ability to lay out the steps involved in creating a pattern. A realistic, practical, and successful electronic jobsheet for making Kebaya Labuh patterns was the goal of this project. The research used an R&D approach, namely the Four-D (4D) development model, which includes the phases of defining the problem, creating a design, creating the product, and finally, distributing it. Students from SMK Negeri 3 Pekanbaru's Fashion Design class in Grade XI participated in the study. Learning outcome assessments, questionnaires, observations, and interviews were used to gather data. The findings indicated that both the material expert validation score of 92.53% and the media expert validation score of 84.33% were considered to be fairly valid. The findings of the practicality test indicated that all three trials the small group trial (91%), the teacher's assessment (93%), and the large group trial (87.55%) were classified as very practical. Additionally, students' learning mastery improved in tandem with an N-Gain score of 0.40 on the effectiveness test, placing it in the moderate category. As a result, the e-jobsheet that was created was deemed valid, practical, and useful for teaching the Kebaya Labuh pattern.]]>
