PENERAPAN TEKNIK MODELLING TERHADAP KETERAMPILAN VOKASIONAL CUCI MOTOR PADA SISWA TUNAGRAHITA RINGAN DI SLB NEGERI CERME

The Application of Modeling Techniques to Improve Motorbike Washing Vocational Skills Among Students with Mild Intellectual Disabilities at SLB Negeri Cerme

Siswa tunagrahita ringan merupakan individu yang memiliki hambatan dalam pertumbuhan, baik dalam bidang akademik, sosial, dan keterampilan. Sehingga belum memiliki kemandirian. Keterampilan vokasional bertujuan untuk meningkatkan kemandirian siswa terhadap kompetensi kerja di masa depan. Namun siswa tunagrahita ringan memerlukan pendekatan khusus dalam pembelajaran vokasional. Maka perlunya diterapkan strategi pembelajaran yang sesuai, salah satunya yaitu penerapan teknik modelling. Penerapan teknik modelling dapat membantu siswa untuk mengimplementasi langkah mencuci motor dan memudahkan siswa saat praktik di lapangan. Penelitian ini bertujuan untuk mengidentifikasi adanya peningkatan dalam menggunakan teknik modelling terhadap kemampuan vokasional cuci motor pada siswa tunagrahita ringan di SLB Negeri Cerme. Penelitian ini menggunakan pendekatan kuantitatif pre-eksperimental, design one group pre-test post-test menggunakan uji Wilcoxon dan SPSS dengan subjek 10 orang. Hasil analisis data menunjukkan nilai pre-test 32,8 lebih kecil dari nilai posrt-test 67,1 setelah diberikan intervensi menggunakan Teknik modelling, pada rumus uji Wilcoxon menunjukkan Zhitung 2,80 > Ztabel 1,96 dan hasil analisis data menunggunakan SPSS menunjukkan nilai Asym. Sig. (2-tailed) 0,005 >0,05. Dengan demikian, dapat disimpulkan bahwa penerapan teknik modelling dapat meningkatkan kemampuan vokasional cuci motor pada siswa tunagrahita ringan di SLB Negeri cerme.

Students with mild intellectual disabilities face notable challenges in academic, social, and practical skill development, often resulting in limited autonomy and a reliance on others for daily activities. Vocational skills training is pivotal in fostering these students' independence, preparing them for future employment competencies. However, students with mild intellectual disabilities frequently require tailored instructional approaches in vocational education, one of which is the application of modeling techniques. Modeling techniques serve to guide students through the step-by-step process of motorbike washing, a vocational skill, by enhancing their comprehension and facilitating practical application in real-world settings. This study seeks to evaluate the effectiveness of modeling techniques in improving the motorbike-washing vocational skills of students with mild intellectual disabilities at SLB Negeri Cerme. Employing a quantitative approach, the study uses a pre-experimental design with a one-group pre-test and post-test structure, analyzed using the Wilcoxon test and SPSS. The research sample comprised ten participants. The data analysis indicated a significant increase from a pre-test mean score of 32.8 to a post-test mean score of 67.1 following the modeling intervention. The Wilcoxon test results showed Zhitung at 2.80, surpassing the Ztable threshold of 1.96, while the SPSS analysis yielded an Asymptotic Significance (2-tailed) value of 0.005, which is less than the 0.05 significance level. These findings support the conclusion that implementing modeling techniques effectively enhances vocational skills, specifically in motorbike washing, among students with mild intellectual disabilities at SLB Negeri Cerme.
