ABSTRAK

PENGARUH PENERAPAN MEDIA TRAINER ANTI-LOCK BREAKING SYTEM  (ABS) TERHADAP HASIL BELAJAR PESERTA DIDIK PADA  MATA PELAJARAN PERAWATAN CHASIS SEPEDA MOTOR .

Pada Penelitian ini peneliti bertujuan  menguji pengaruh media pembelajaran "trainer Anti-lock Braking System (ABS)" terhadap hasil  belajar  pesrta didik  di SMK Kartanegara Kediri. Metode yang digunakan adalah quasi eksperimen dengan desain one grup Pre-test dan Post-test pada kelompok eksperimen. Hasil belajar diukur menggunakan tes pilihan ganda 25 soal dan dianalisis dengan SPSS 27.

Pada Penelitian kali ini data dianalisis menggunakan SPSS 27 melalui uji prasyarat normalitas, paired sample t-test, dan uji N-Gain. Uji normalitas menunjukkan data pre-test dan post-test terdistribusi normal dengan signifikansi Shapiro-Wilk masing-masing 0.296 dan 0.768 (>0.05). Paired sample t-test menunjukkan perbedaan signifikan antara hasil belajar sebelum dan sesudah penerapan trainer ABS dengan nilai signifikansi 0.00 (<0.05) juga mendapatkan nilai r sebesar 0,321 dan t sebesar 2,089,Dimana kemputusan diterima karena thit>ttable yaitu sebesar 2,037 menunjukkan media ini dapat meningkatkan hasil belajar siswa. Hasil perhitungan N-Gain menunjukkan nilai rata-rata 0.610 (kategori "Sedang") dan persentase efektivitas 61% (kategori "Cukup efektif"). Kesimpulannya, penggunaan trainer ABS sebagai media ajar berpengaruh dan cukup efektif dalam meningkatkan hasil belajar siswa.

THE EFFECT OF USING AN ANTI-LOCK BRAKING SYSTEM (ABS) TRAINER ON STUDENT LEARNING OUTCOMES IN MOTORCYCLE CHASSIS MAINTENANCE COURSE

In this study, the researcher aimed to examine the effect of the "Anti-lock Braking System (ABS) trainer" instructional media on students' learning outcomes at SMK Kartanegara Kediri. The method used was a quasi-experimental design with a one-group pre-test and post-test on the experimental group. Learning outcomes were measured using a 25-item multiple-choice test and analyzed using SPSS 27.

In this study, data were analyzed using SPSS 27 through tests for normality assumptions, paired sample t-test, and N-Gain test. Normality tests indicated that both pre-test and post-test data were normally distributed with Shapiro-Wilk significance values of 0.296 and 0.768 (>0.05) respectively. The paired sample t-test showed a significant difference between learning outcomes before and after the implementation of the ABS trainer, with a significance value of 0.00 (<0.05). It also obtained an effect size (r) of 0.321 and a t-value of 2.089. The decision was accepted because thit > ttable, which was 2.037, indicating that this media can improve student learning outcomes.The N-Gain calculation resulted in an average value of 0.610 (category "Moderate") and an effectiveness percentage of 61% (category "Sufficiently effective"). In conclusion, the use of the ABS trainer as an instructional media has a significant and moderately effective impact on improving student learning outcomes.
