Abstract
The automotive industry, particularly the tire sector, faces increasing demand amid global transformation; however, the curing process remains inefficient, with an average Overall Equipment Effectiveness (OEE) of 68.65%, below the company’s target (78.51%) and the world-class standard (85%). This study aims to improve curing process productivity through the integration of OEE, Six Big Losses, Root Cause Failure Analysis (RCFA), Failure Mode and Effect Analysis (FMEA), and 5W1H. Six-month data (July–December 2024) were analyzed to identify the factors contributing to low OEE. The Six Big Losses analysis revealed breakdown losses (35.40%) and setup & adjustment losses (28.70%) as dominant causes, while RCFA identified root problems in unloader, lowring, and topring failures, as well as weak preventive maintenance practices. FMEA was applied to prioritize corrective actions based on the highest Risk Priority Number (RPN), followed by strategy formulation using the 5W1H approach. Improvements included replacement of critical components, SOP standardization, technician training, and development of a timer dashboard. As a result, OEE increased to 82.46%, with a peak of 85.12%, accompanied by significant improvements in availability (86.21% → 91.34%), performance (78.65% → 84.52%), and quality (97.85% → 99.21%). Furthermore, downtime was reduced by 21.70% and defect rate decreased by 1.36%. These findings demonstrate that the integration of OEE, Six Big Losses, RCFA, FMEA, and 5W1H is effective in enhancing curing process productivity and supports the achievement of world-class manufacturing standards. Keywords: OEE, Six Big Losses, RCFA, FMEA, 5W1H, Curing Process Industri otomotif, khususnya sektor ban kendaraan bermotor, menghadapi peningkatan permintaan seiring transformasi global, namun efektivitas proses curing masih rendah dengan nilai Overall Equipment Effectiveness (OEE) rata-rata 68,65%, di bawah target perusahaan (78,51%) maupun standar world-class (85%). Penelitian ini bertujuan meningkatkan produktivitas curing process melalui integrasi metode OEE, Six Big Losses, Root Cause Failure Analysis (RCFA), Failure Mode and Effect Analysis (FMEA), serta 5W1H. Data enam bulan (Juli– Desember 2024) dianalisis untuk mengidentifikasi faktor penyebab rendahnya OEE. Hasil analisis Six Big Losses menunjukkan breakdown losses (35,40%) dan setup & adjustment losses (28,70%) sebagai penyebab dominan, sedangkan RCFA mengungkap akar masalah pada kerusakan unloader, lowring, topring, shaping, serta lemahnya preventive maintenance. FMEA digunakan untuk menentukan prioritas perbaikan berdasarkan nilai Risk Priority Number (RPN), kemudian strategi perbaikan diformulasikan dengan pendekatan 5W1H. Implementasi perbaikan meliputi penggantian komponen kritis, standarisasi SOP, pelatihan teknisi, dan pengembangan dashboard timer setting. Hasilnya, nilai OEE meningkat menjadi 82,46% dengan capaian tertinggi 85,12%, disertai perbaikan signifikan pada aspek availability (86,21% → 91,34%), performance (78,65% → 84,52%), dan quality (97,85% → 99,21%). Selain itu, downtime berhasil ditekan sebesar 21,70% dan defect rate menurun 1,36%. Temuan penelitian ini menegaskan bahwa integrasi metode OEE, Six Big Losses, RCFA, FMEA, dan 5W1H terbukti efektif dalam meningkatkan produktivitas proses curing sekaligus mendukung pencapaian standar world-class manufacturing. Kata Kunci: OEE, Six Big Losses, RCFA, FMEA, 5W1H, Curing Process
