Abstract

Proyek fit out showroom dan kantor menghadapi risiko pemborosan karena pekerjaan interior, material khusus, sistem mekanikal-elektrikal, dan persetujuan teknis harus dikoordinasikan pada area kerja yang terbatas. Penelitian ini bertujuan mengidentifikasi dan menganalisis waste pada Proyek New Showroom Interior Construction PT Daelim Dobidos Indonesia di Capital Cove Business Loft Unit 29 dan 30, BSD City. Proyek mencakup luas sekitar 538 m² dengan pelaksanaan Januari hingga April 2025. Penelitian menggunakan pendekatan deskriptif kuantitatif berdasarkan tujuh kategori Lean Construction, yaitu defect, waiting, transportation, inventory, motion, over processing, dan over production. Data diperoleh melalui observasi, wawancara, dokumentasi proyek, dan kuesioner skala Likert kepada seluruh 15 personel proyek menggunakan total sampling. Instrumen terdiri atas 28 pernyataan, masing-masing empat untuk setiap kategori waste. Pengolahan data memanfaatkan SPSS melalui uji korelasi Pearson, koefisien Cronbach's Alpha, serta analisis rerata. Seluruh butir dinyatakan valid berdasarkan ambang r tabel 0,514, sedangkan seluruh variabel mempunyai koefisien reliabilitas di atas 0,70. Transportation menjadi waste dominan dengan rerata 4,27, diikuti defect sebesar 4,22 dan waiting sebesar 4,18. Hasil observasi mengaitkan pemborosan tersebut dengan jalur distribusi material yang tidak langsung, kesalahan pemasangan, keterlambatan persetujuan, serta ketergantungan antarpaket pekerjaan. Rekomendasi perbaikan mencakup penataan zona logistik, pengaturan kedatangan material, klarifikasi gambar kerja, pemeriksaan mutu bertahap, dan koordinasi jangka pendek. Temuan ini memberikan dasar prioritas perbaikan khusus proyek, tetapi belum membuktikan besarnya penurunan waste setelah intervensi dilaksanakan.
