Abstract

Mesin reng CV. Ali Griya, yang digunakan untuk memproduksi atap baja ringan jenis reng V belum sepenuhnya bekerja secara efektif. Hal ini ditunjukkan dengan adanya downtime, penurunan kecepatan produksi mesin, dan menghasilkan produk-produk yang tidak sesuai standard yang telah ditetapkan.  Penelitian ini bertujuan untuk mengukur dan mengetahui tingkat efektivitas mesin reng dengan menggunakan metode Overall Equipment Effectiveness (OEE), mengidentifikasi faktor penyebab six big losses dengan menggunakan Fault Tree Analysis (FTA), dan memberikan usulan perbaikan untuk meningkatkan tingkat efektivitas mesin.

             Dari hasil penelitian,  OEE mesin reng mencapai rata-rata 57,55%, dan masih berada di bawah nilai OEE ideal (85%). Usulan perbaikan yang direkomendasikan meliputi eliminasi six big losses, mengembangkan program pemeliharaan, dan memberikan pelatihan untuk meningkatkan kemampuan maintenance dan operasional.

 

Abstract

 

             The analysis of reng machine effectiveness by using Overall Equipment Effectiveness (OEE) and Fault Tree Analysis (FTA) method in  CV. Ali  Griya, Semarang. The reng machine of CV. Ali Griya, which is used to produce  lightweight steel roof with a kind V reng, has not fully worked effectively. This is indicated by the presence of downtime, speed losses, and produce products that are not according to standards that have been determined. This study aims to measure and determine the level of effectiveness of reng machine using Overall Equipment Effectiveness (OEE) method, identify factors that cause six big losses by using Fault Tree Analysis (FTA), and proposes improvements to increase the effectiveness of the machine.

             From the research, OEE of reng machine reached an average of 57.55%, and still was below the ideal OEE (85%). Proposed improvements that recommended include the elimination of six big losses, develop a maintenance program, and provide training to improve the ability of maintenance and operations.
