      "abstract": "PT. XYZ merupakan perusahaan manufaktur yang memproduksi pipa baja (heavy\r\nindustries), kondisi saat ini belum menunjukan pencapaian produktivitas yang baik\r\ndan stabil, rendahnya efisiensi dan efektifitas terlihat pada pencapaian FY 2020 2024,\r\narea\r\nslitter\r\n10.956-12.218\r\nKg\/Jam\r\n(target:\r\n12.100\r\nKg\/Jam),\r\narea\r\nmill\r\n3\r\n1.8152.079\r\n\r\nKg\/Jam (target: 1.900 Kg\/Jam). Penelitian ini bertujuan mengoptimalkan\r\nproses di PT XYZ menggunakan pendekatan lean manufacturing berbasis OTRS\r\n(Operating Time Research Software) untuk analisis dan identifikasi bottleneck dan\r\nwaste, metode 5 Why + 1H  untuk mencari akar masalah,  kaizen sebagai action\r\nplan dari RCA. Sedangkan nilai ROI, payback dan RA digunakan untuk mengukur\r\npengaruh financial effectiveness dan safety  dari kaizen. Hasil kaizen di area slitter\r\ndan mill 3 teridentifikasi bottleneck terjadi pada operator slitter dan mill 3\r\nditunjukan dengan ketidakseimbangan antara cycle time dan takt time karena\r\ntingginya frekuensi set up mesin, aktivitas handling, ketidak sesuaian standar kerja,\r\nketerlambatan kordinasi dan hal lainya. waste berupa waiting 3 item, transportation\r\n1 item, over process 1 item, motion 2 item dan defect 2 item. Kemudian diselesaikan\r\ndengan kaizen seperti penambahan jembatan, review instruksi kerja, penggunaan\r\nsupport beam, apron bersaku, relayout mesin uji dan lainnya. kaizen telah\r\nberpengaruh pada efisiensi di proses slitter dan mill 3 dengan hasil pencapaian pada\r\noperator slitter: 2127 detik menjadi 1419 detik, performa naik 23%, operator mill\r\n3: 1238 detik menjadi 1024 detik, performa naik 8,33% dan terjadi redistribusi\r\naktivitas kerja ke operator cut man 1: 814,08 detik menjadi 952,64 detik, cut man\r\n2: 787,76 menjadi 981,96 detik. Sedangkan financial effectiveness pada nilai\r\nROI:34%, payback period: 7,4 hari serta penurunan nilai RA slitter: 14 menjadi 5,\r\nRA mill 3: 17 menjadi 6. Penelitian ini menyimpulkan bahwa integrasi lean\r\nmanufacturing berbasis OTRS sangat efektif.",
