Abstract
This research was conducted to analyze the effectiveness of the tubular oven machine at PT. Usaha Saudara Mandiri using the Overall Equipment Effectiveness (OEE) method and to identify the main sources of equipment losses through the Six Big Losses approach. The primary issue observed was high machine downtime, which significantly affected the OEE value and resulted in unmet production targets. A quantitative descriptive method was applied, with data collected through observation, interviews, and documentation from September 2024 to February 2025. The results showed that the average OEE value of the tubular oven machine was only 44%, far below the world-class standard of 85%, with the most significant losses caused by reduce speed losses and idle & minor stoppages. Further analysis using Pareto and fishbone diagrams indicated that the root causes stemmed from insufficient operator skills, unstandardized work methods, and a lack of scheduled maintenance. Based on these findings, improvement proposals were developed using the Total Productive Maintenance (TPM) framework, focusing on operator training, autonomous maintenance, and planned maintenance strategies. The implementation of TPM is expected to enhance machine performance, minimize production losses, and support the company’s operational efficiency in a sustainable manner. Keywords: Total Productive Maintenance, Overall Equipment Effectiveness, Six Big Losses, Oven Tubular Penelitian ini dilakukan untuk menganalisis efektivitas mesin oven tubular di PT. Usaha Saudara Mandiri menggunakan metode Overall Equipment Effectiveness (OEE) serta mengidentifikasi kerugian utama melalui pendekatan Six Big Losses. Permasalahan utama yang dihadapi adalah tingginya downtime mesin yang berdampak pada rendahnya nilai OEE dan kegagalan mencapai target produksi. Penelitian ini menggunakan pendekatan kuantitatif dengan pengumpulan data melalui observasi, wawancara, dan dokumentasi selama periode September 2024 hingga Februari 2025. Hasil penelitian menunjukkan bahwa nilai rata-rata OEE mesin oven tubular hanya mencapai 44%, jauh di bawah standar kelas dunia sebesar 85%, dengan faktor kerugian terbesar berasal dari reduce speed losses dan idle & minor stoppages. Analisis lebih lanjut dengan diagram Pareto dan fishbone mengungkapkan bahwa penyebab utama terletak pada keterampilan operator, metode kerja yang kurang standar, dan kurangnya pemeliharaan terjadwal. Berdasarkan temuan tersebut, disusun usulan perbaikan berbasis Total Productive Maintenance (TPM), terutama melalui peningkatan pelatihan operator, pelaksanaan autonomous maintenance, dan pemeliharaan terencana. Penerapan TPM diharapkan dapat meningkatkan kinerja mesin, mengurangi kerugian produksi, dan mendukung efisiensi operasional perusahaan secara berkelanjutan.
