Abstract

Work Preparation Sheet (WPS) sangat penting sebagai panduan terstruktur yang memastikan setiap tahapan pekerjaan dieksekusi secara sistematis, aman, dan efisien demi meminimalkan risiko kesalahan di lapangan. Penelitian ini bertujuan untuk menganalisis efektivitas implementasi Work Preparation Sheet (WPS) berbasis standar World Skills Competition (WSC) dalam meningkatkan hasil praktik pemesinan bubut, khususnya pada pembuatan Handle Tool Post. Permasalahan utama yang melatarbelakangi penelitian ini adalah rendahnya kemandirian siswa dalam merencanakan urutan kerja serta kesalahan penentuan parameter pemotongan yang berdampak pada rendahnya presisi produk dan efisiensi waktu. Metode penelitian yang digunakan adalah kuantitatif dengan desain Quasi-Experimental (Posttest-Only Control Group Design). Subjek penelitian terdiri dari 68 siswa kelas XI Teknik Pemesinan SMKN 1 Singosari yang dibagi menjadi kelompok kontrol dan kelompok eksperimen. Data dikumpulkan melalui observasi unjuk kerja, penilaian dimensi produk, dan evaluasi waktu kerja, kemudian dianalisis menggunakan uji-t sampel independen. Hasil penelitian menunjukkan bahwa penggunaan WPS berbasis WSC secara signifikan meningkatkan nilai rata-rata praktik siswa dari 71,5 pada kelompok kontrol menjadi 85,88 pada kelompok eksperimen. Implementasi ini terbukti efektif dalam meningkatkan akurasi geometris, efisiensi waktu pengerjaan, serta menurunkan angka kegagalan produk (reject). Dapat disimpulkan bahwa penerapan WPS berbasis standar WSC mampu membentuk pola pikir sistematis dan kompetensi psikomotorik siswa sesuai dengan tuntutan standar industri internasional.

Abstract

Developing 21st-century competencies particularly an innovative mindset is crucial for Vocational High School (SMK) students to navigate the dynamic challenges of the manufacturing industry. Conventional instruction in machining workshops often prioritizes technical skills (hard skills) while neglecting the cultivation of creative problem-solving abilities. This study aims to analyze the impact of implementing product prototyping practices using a Design Thinking approach on enhancing the innovative mindset of 11th-grade students specializing in Machining Engineering. A descriptive quantitative research method was employed, featuring the implementation of design thinking-based product prototyping practices as the independent variable (X) and the enhancement of an innovative mindset as the dependent variable (Y). Data regarding the improvement of the innovative mindset were collected via a questionnaire consisting of closed-ended questions and statements, requiring students to select from pre-determined response options. The results indicate that design thinking-based prototyping practices enable students to enhance their innovative mindset. This outcome is attributed to the design thinking process, which trains students to understand problems, identify and analyze needs, discover optimal solutions, create products based on discussed solutions, and test those products with the individuals experiencing the problems.
