Abstract

Overall Equipment Effectiveness (OEE) adalah suatu metode yang digunakan untuk mengukur kinerja mesin produksi dengan mengintegrasikan aspek Availability, Performance, dan Quality serta mengidentifikasi enam kategori kerugian terbesar sebagai penyebab utama dari rendahnya efisiensi. PT. XYZ, yang beroperasi dalam bidang distribusi dan layanan produksi baja, memanfaatkan mesin CNP untuk memproduksi profil baja konstruksi secara berkelanjutan dengan volume yang tinggi. Namun, mesin ini sering mengalami masalah operasional. Penelitian ini bertujuan untuk mengukur tingkat efektivitas mesin CNP sekaligus mengidentifikasi faktor kerugian yang paling signifikan menggunakan pendekatan Six Big Losses. Metode penelitian adalah deskriptif kuantitatif dengan melakukan pengamatan langsung di area produksi selama 15 hari kerja pada periode 12 Februari hingga 6 Maret 2026. Hasil penelitian menunjukkan bahwa nilai rata-rata OEE mesin CNP di PT. XYZ adalah sebesar 40,94%, dengan rincian Availability 60,65%, Performance 67,96%, dan Quality 98,46%. Nilai OEE tersebut masih jauh di bawah standar kelas dunia sebesar 85%. Berdasarkan analisis menggunakan Diagram Pareto, ditemukan tiga faktor penyumbang kerugian terbesar (mencapai akumulasi 91%) yaitu Set Up and Adjustment Losses (33,00%), Reduced Speed Losses (19,20%), dan Idling and Minor Stoppages (15,64%). Analisis akar masalah yang diperdalam dengan Diagram Fishbone menunjukkan bahwa kerugian tersebut utamanya disebabkan oleh belum adanya Standard Operating Procedure (SOP) yang memadai, kurangnya pelatihan operator, penerapan perawatan yang masih reaktif, serta terbatasnya fasilitas logistik seperti crane. Hasil dari penelitian ini merekomendasikan penerapan preventive maintenance, penyusunan SOP untuk kalibrasi kecepatan mesin dan ukuran sesuai standar, pengetatan Quality Control material, serta perbaikan tata letak area kerja untuk meningkatkan efektivitas mesin secara berkelanjutan. ***** Overall Equipment Effectiveness (OEE) is a method used to measure the performance of production machines by integrating the aspects of Availability, Performance, and Quality, as well as identifying the six major categories of losses as the main causes of low efficiency. PT. XYZ, which operates in the field of steel distribution and production services, utilizes a CNP machine to continuously produce structural steel profiles in high volumes. However, this machine frequently experiences operational issues. This research aims to measure the effectiveness level of the CNP machine while simultaneously identifying the most significant loss factors using the Six Big Losses approach. The research method is quantitative descriptive, conducted through direct observation in the production area for 15 working days during the period of February 12 to March 6, 2026. The results showed that the average OEE value of the CNP machine at PT. XYZ is 40.94%, detailing an Availability of 60.65%, Performance of 67.96%, and Quality of 98.46%. This OEE value is still far below the world-class standard of 85%. Based on the analysis using a Pareto Chart, three major contributing factors to the losses were identified (reaching an accumulation of 91%), namely Set Up and Adjustment Losses (33.00%), Reduced Speed Losses (19.20%), and Idling and Minor Stoppages (15.64%). The root cause analysis, further detailed with a Fishbone Diagram, indicates that these losses are primarily caused by the absence of adequate Standard Operating Procedures (SOP), lack of operator training, the application of reactive maintenance, and limited logistical facilities such as cranes. The results of this study recommend the implementation of preventive maintenance, the drafting of SOPs for machine speed and size calibration according to standards, stricter material Quality Control, and layout improvements in the work area to continuously enhance machine effectiveness.
