Development of Interactive Learning Media Using Scratch on the Learning Outcomes of Fiber Optic Network for Grade X TJKT Students

Abstract

This study aims to develop Scratch-based learning media on fiber optic material, assess the feasibility of the learning media, and examine students’ responses regarding their interest in the designed media. This research uses the Research and Development (R&D) method with the MDLC (Multimedia Development Life Cycle) model by Rickman Roedavan. The research subjects were 32 Grade X TJKT students at SMK Taruna. Data collection techniques included observation, interviews, documentation, and questionnaires. Instrument validation was conducted by subject matter experts and media experts. Product testing involved a practicality test with both teachers and students. This study resulted in Scratch-based learning media on fiber optic material. The research findings revealed that the learning media "Sertic" (Serat Optic) was validated by validators through a rating questionnaire to determine the feasibility of the developed application. The validity score percentage given by the subject matter expert was 82.63%, categorized as “Highly Feasible,” while the validity score percentage from the media expert was 82.39%, also categorized as “Highly Feasible.” The validated product was then tested with teachers and students, accompanied by a response questionnaire guided by the researcher to determine the level of practicality. The teacher practicality score was 91.58%, categorized as “Highly Practical,” and the student practicality score was 82.63%, also categorized as “Highly Practical.”
