Value Stream Mapping, Lean Manufacturing, Waste, Process Cycle Efficiency, Ulir BautAbstract
Peningkatan efisiensi proses produksi tidak hanya ditentukan oleh kecepatan aktivitas bernilai tambah, tetapi juga oleh kemampuan sistem mengendalikan aktivitas yang tidak memberikan nilai tambah. Penelitian ini bertujuan memetakan aliran proses pembuatan ulir baut, mengidentifikasi waste, dan merancang kondisi perbaikan menggunakan Value Stream Mapping (VSM). Penelitian menggunakan pendekatan deskriptif kuantitatif melalui observasi langsung dan pengukuran waktu pada tiga tahapan utama, yaitu pemotongan dan pengukuran, pembuatan drat dengan mesin bubut konvensional, dan proses senai. Sebanyak 30 aktivitas diamati dengan 10 kali pengukuran waktu pada setiap aktivitas. Hasil Current VSM menunjukkan lead time 1.476,3 detik, terdiri atas 731,3 detik Value Added, 378,8 detik Necessary but Non Value Added, dan 366,2 detik Non Value Added. Process Cycle Efficiency (PCE) awal sebesar 49,54%. Waste dominan adalah over processing 22,92% dan waiting 20,38%. Usulan perbaikan berupa persiapan alat dan bahan, penataan area kerja, standardisasi parameter, penggunaan jig atau stopper, thread gauge, serta relokasi penyimpanan menghasilkan lead time 818,4 detik dan PCE 52,10%. Dengan demikian, VSM dapat digunakan untuk mengurangi aktivitas non-value-added dan memperbaiki aliran proses produksi ulir baut.
