<![CDATA[The effectiveness of production machinery is a crucial factor in supporting the operational performance of manufacturing companies, particularly in achieving quality standards, cost efficiency, and delivery timeliness. CV ABC, a garment company, experienced a decrease in productivity due to the high number of defective products and the frequency of sewing machine breakdowns that caused downtime. The focus of this research is the analysis and evaluation of the effectiveness of the machine. The goal is to determine the level of effectiveness in the use of equipment or machinery using the Overall Equipment Effectiveness (OEE) method. This study is very important because it identifies the factors that cause the decline in effectiveness based on the Six Big Losses measurement. The research was conducted by collecting production data during the period from January to December 2024. The three main components of OEE analyzed include: availability, performance efficiency, and rate of product quality. The average OEE value of 54.27% indicates that the machine has not operated effectively according to the JIPM standard (85%). Based on the analysis of Six Big Losses, the highest losses came from quality defects of 10.5%, with the main causes being frequent engine stops during the production process, the length of the reset process, and delays in replacing parts. To overcome these problems, it is recommended to provide training to operators, improve the schedule and quality of machine maintenance, maintain a clean work environment, and ensure that all production activities are carried out in accordance with Standard Operating Procedures (SOP). This research contributes to continuous improvement in decision-making to improve the operational effectiveness of production machines. EVALUASI EFEKTIVITAS MESIN PRODUKSI MENGGUNAKAN METODE OVERALL EQUIPMENT EFFECTIVENESS (OEE)Efektivitas mesin produksi merupakan faktor krusial dalam mendukung kinerja operasional perusahaan manufaktur, khususnya dalam memenuhi standar kualitas, efisiensi biaya, dan ketepatan waktu pengiriman. CV ABC, sebuah perusahaan garmen, mengalami penurunan produktivitas akibat tingginya produk cacat dan frekuensi kerusakan mesin jahit yang menyebabkan downtime. Fokus penelitian ini adalah analisis dan evaluasi efektivitas mesin. Tujuannya adalah untuk menentukan tingkat efektivitas pemakaian peralatan atau mesin dengan menggunakan metode Overall Equipment Effectiveness (OEE). Penelitian ini sangat penting karena mengidentifikasi faktor penyebab penurunan efektivitas yang didasarkan pada pengukuran Six Big Losess. Penelitian dilakukan dengan mengumpulkan data produksi dalam rentang waktu Januari sampai Desember 2024. Tiga komponen utama OEE yang dianalisis meliputi: availability, performance efficiency, dan rate of quality product. Hasil nilai OEE rata-rata sebesar 54,27% mengindikasikan bahwa mesin belum beroperasi secara efektif sesuai standar JIPM (85%). Berdasarkan analisis Six Big Losses, kerugian tertinggi berasal dari quality defect sebesar 10,5%, dengan penyebab utama berupa seringnya mesin berhenti saat proses produksi, lamanya proses penyetelan ulang, dan keterlambatan penggantian suku cadang. Untuk mengatasi permasalahan tersebut, disarankan memberikan pelatihan kepada operator, meningkatkan jadwal dan kualitas perawatan mesin, menjaga kebersihan lingkungan kerja, serta memastikan seluruh aktivitas produksi dilakukan sesuai dengan Standard Operating Procedure (SOP). Penelitian ini memberikan kontribusi dalam pengambilan keputusan perbaikan berkelanjutan guna meningkatkan efektivitas operasional mesin produksi.]]>
