Abstract

This study evaluates the contextual relevance of introducing Lean Construction to Vocational High School (SMK) students in Indonesia through a triangulation assessment of student workshop responses, curriculum alignment, and graduate employment data over three years. The novelty of this study lies in the simultaneous assessment of all three dimensions at the vocational education level, a topic that has rarely been addressed in the Lean Construction education literature. A short workshop combining a Lean Construction lecture and a LEGO-based Last Planner System® (LPS) simulation was conducted with 59 12th-grade students in the Building Construction, Sanitation, and Maintenance (KGSP) program at SMKN 26 Jakarta. Results indicated that 98% of students rated Lean Construction as important or very important, and 83.05% expressed interest in learning more. Curriculum analysis of official Learning Outcomes (Capaian Pembelajaran/CP) documents confirmed that Lean principles were not included in Phase E or Phase F Learning Outcomes. Three-year tracer study data (210 graduates from the 2023-2025 cohort) consistently indicated that the construction sector was the primary employment destination for employed graduates. This paper argues that the existing KGSP curriculum provides a strong technical foundation and can be enriched by integrating Lean principles into existing courses, particularly for graduates working in drafter and inspector roles.

Abstrak

Studi ini mengevaluasi relevansi kontekstual pengenalan Konstruksi Ramping kepada siswa Sekolah Menengah Kejuruan (SMK) di Indonesia melalui penilaian triangulatif terhadap respons siswa terhadap workshop, keselarasan kurikulum, serta data pekerjaan lulusan selama tiga tahun. Kebaruan penelitian ini terletak pada pengkajian ketiga dimensi tersebut secara simultan pada tingkat pendidikan vokasi, yang selama ini masih jarang menjadi sasaran dalam literatur pendidikan Konstruksi Ramping. Workshop singkat yang menggabungkan kuliah Konstruksi Ramping dan simulasi Last Planner System® (LPS) berbasis LEGO dilaksanakan kepada 59 siswa kelas XII program Konstruksi Gedung, Sanitasi, dan Perawatan (KGSP) di SMKN 26 Jakarta. Hasil menunjukkan bahwa 98% siswa menilai Konstruksi Ramping penting atau sangat penting dan 83,05% menyatakan minat untuk mempelajari lebih lanjut. Analisis kurikulum terhadap dokumen resmi Capaian Pembelajaran (CP) mengonfirmasi bahwa prinsip-prinsip Lean belum tercantum dalam Capaian Pembelajaran Fase E maupun Fase F. Data tracer study selama tiga tahun (210 lulusan dari angkatan 2023-2025) secara konsisten menunjukkan bahwa sektor konstruksi menjadi tujuan kerja utama bagi lulusan yang bekerja. Makalah ini berargumen bahwa kurikulum KGSP yang ada telah menyediakan fondasi teknis yang kuat dan dapat diperkaya melalui integrasi prinsip-prinsip Lean ke dalam mata pelajaran yang sudah ada, khususnya bagi lulusan yang bekerja pada peran drafter dan inspector.
