Abstract: This study aims to determine the effect of using an Android-based e-book learning medium covering Electronic Fuel Injection (EFI) system components on the understanding of vocational high school (SMK) students. The study employed a quantitative approach using a pre-experimental design—specifically, the One-Group Pretest-Posttest Design. The sample consisted of 34 tenth-grade students from the Light Vehicle Engineering (TKR) program, selected using purposive sampling. Data collection was conducted via pretests and posttests using multiple-choice test instruments. Data analysis techniques included descriptive statistics, the Shapiro-Wilk normality test, the N-Gain test, and hypothesis testing using a paired sample t-test. The results showed that the students' average pretest score of 62.65 increased to 74.56 in the posttest. The N-Gain test yielded a score of 0.333, falling into the medium category. Hypothesis testing revealed a significance value of 0.000 (less than 0.05); thus, the null hypothesis (H₀) was rejected, and the alternative hypothesis (H₁) was accepted. Consequently, it can be concluded that the use of the Android-based e-book learning medium significantly influenced the SMK students' understanding of the Electronic Fuel Injection (EFI) system. The Android-based e-book is considered effective in enhancing student understanding due to its interactive interface, ease of accessibility, and support for independent learning.
