Development of an Android-Based Practical E-Module on Remote Server Topics for Grade XI TKJ Students at SMK Negeri 1 Solok

Abstract

This research was motivated by the development of an Android-based practical work e-module, considered the most relevant solution to address the limitations of existing teaching materials. This e-module integrates learning content, practical procedure steps, circuit visualizations, and supporting media—such as images and videos—into a single, easily accessible platform. Furthermore, the fact that most students already own Android devices allows for flexible use of the e-module both inside and outside the classroom. The objectives of this research were to develop an Android-based practical work e-module on the topic of Remote Servers for Grade XI TKJ (Computer and Network Engineering) students at SMK Negeri 1 Solok, and to determine the validity and practicality of the developed e-module. The study employed the Research and Development (R&D) method, which aims to produce and test the effectiveness of specific products—whether software, hardware, learning media, curricula, or instructional models. Media validation results showed a score of 91.53% (categorized as "highly valid"), while content validation results showed a score of 92.73% (also "highly valid"). The media's strength lay in the readability of text and images, which achieved the highest score of 97.92%, while the content's strength lay in the use of easily understandable language, scoring 95.83%. Regarding practicality, teacher assessments yielded a score of 87.50% ("highly practical"), and student assessments yielded 89.51% ("highly practical"). Based on student assessments, the e-module's greatest strength was the clarity of practical steps (90.36%), while the aspect with room for further improvement was the visual appeal (88.48%). Thus, the developed Android-based practical work e-module is deemed highly valid and highly practical for use as a learning support tool for the Remote Server topic.
