PROSES ASSESSIBILITY AND DUCTING UTILITIES DENGAN PENDEKATAN LEAN CONSTRUCTION

Ade Astuti Widi Rahayu

Abstract


ABSTRAK Penelitian ini memiliki beberapa tujuan yaitu untuk melakukan analisis dan identifikasi aktivitas-aktivitas pada proses assessibility and ducting utilities, yang merupakan aktivitas yang menambah nilai (value added) dan aktivitas yang tidak menambah nilai (non value added) beserta nilai peningkatan dan reduksi waste, kemudian menyusun usulan perbaikan sistem proses assessibility and ducting utilities dan mengevaluasi kualitas hasil kerja yang dihasilkan, sehingga produktivitas perusahaan dapat tercapai. Metode yang digunakan adalah dengan menerapkan Lean Construction. Analisa proses Assessibility and Ducting Utilities menggunakan konsep Critical Path Method (CPM) dan Value Engineering (VE) dimulai dengan melakukan observasi yang di fokuskan pada tahapan proses Assessibility and Ducting Utilities. Penerapan Lean Construction telah berhasil mengevaluasi dan mengurangi waste yang terjadi pada proses assessibility and ducting utilities. Pemborosan terbanyak adalah pada proses penggalian. Upaya minimasi pemborosan pada proses penggalian adalah dengan cara mereduksi waktu tunggu dan reduksi biaya rental alat berat yang digunakan pada saat proses penggalian. Upaya perbaikan adalah dengan meniinimasi waktu dengan menggunakan CPM, yang dapat berkaitan dengan value dan rental alat.

Kata Kunci: Lean Construction, Value Added, Non Value Added, Critical Path Method (CPM) and Value Engineering (VE)
