Abstract
The automotive manufacturing industry in Indonesia continues to grow in line with the increasing demand for vehicles and rising global competition. However, achieving production targets is often hindered by low machine effectiveness. One of the major issues is that the Overall Equipment Effectiveness (OEE) value of tire building machines remains below the world-class manufacturing standard of 85%. This study aims to identify the factors contributing to the low machine effectiveness and to develop improvement strategies to enhance production performance. The analysis was conducted using the OEE framework through Six Big Losses. Root cause identification was carried out using Root Cause Failure Analysis (RCFA), the 5-Why’s method, Cause-and-Effect Diagram, and Failure Mode Effect and Criticality Analysis (FMECA). The findings indicate that the Six Big Losses have impact on machine effectiveness. Based on the FMECA analysis, improvement priorities were focused on carcass servicer failure and transferring failure, particularly through corrective actions on the clamp brake (RPN 384) and conveyor belt (RPN 392). The main recommendations include the implementation of regular inspection procedures and refresher training for operators. The implementation of these corrective actions successfully increased OEE values by 7.67%.

Namun, pencapaian target produksi masih sering terhambat akibat rendahnya efektivitas mesin. Salah satu masalah yang muncul adalah nilai Overall Equipment Effectiveness (OEE) pada mesin tire building masih di bawah standar world class manufacturing sebesar 85%. Penelitian ini bertujuan mengidentifikasi faktor penyebab rendahnya efektivitas mesin serta merumuskan strategi perbaikan untuk meningkatkan kinerja produksi. Analisis dilakukan dengan pendekatan OEE melalui six big losses. Identifikasi akar masalah dilakukan menggunakan Root Cause Failure Analysis (RCFA), analisis 5-Why’s, Cause and Effect Diagram, serta Failure Mode Effect and Criticality Analysis (FMECA). Hasil penelitian menunjukkan bahwa six big losses menjadi pengarih dalam efektivitas mesin. Berdasarkan analisis FMECA, prioritas perbaikan difokuskan pada carcass servicer failure dan transfering failure melalui perbaikan clamp brake (RPN 384) dan conveyor belt (RPN 392). Rekomendasi utama adalah penerapan prosedur pengecekan berkala dan pelatihan ulang bagi operator. Implementasi langkah perbaikan tersebut berhasil meningkatkan nilai OEE sebesar 7,67%.
