Abstract

NAZLA KHOIRUNNISA, Analisis Overall Equipment Effectiveness dalam Meningkatkan Keandalan Mesin Mazak HCN 4000 II di PT Pindad Enjiniring Indonesia. Dibimbing oleh SUHENDI IRAWAN. Mesin Mazak HCN 4000 II di PT Pindad Enjiniring Indonesia merupakan peralatan penting dalam proses produksi poros perata. Oleh karena itu keandalan pada mesin Mazak HCN 4000 II harus menjadi faktor yang fokus dijaga agar sesuai standar. Namun pada realitanya masih terjadi downtime cukup fluktuatif. Penelitian ini bertujuan untuk menilai seberapa handal mesin Mazak HCN 4000 II dengan menghitung Overall Equipment Effectiveness (OEE), mengidentifikasi kategori kerugian tertinggi melalui indikator Six Big Losses. Serta menemukan akar penyebab dan menentukan solusi perbaikan melalui Fault Tree Analysis (FTA). Hasil analisis kinerja mesin Mazak HCN 4000 II pada periode Juni hingga November 2024 menunjukan nilai OEE sebesar 61% yang terdiri dari availability sebesar 92%, performance sebesar 66%, dan quality yield sebesar 99%. Adapun kerugian Six Big Losses tertinggi yang berkontribusi menurunkan kehandalan mesin adalah idling and minor stoppage sebesar 31,90%.

NAZLA KHOIRUNNISA, Analysis of Overall Equipment Effectiveness in Increase the Reliability of Mazak HCN 4000 II Machine at PT Pindad Enjiniring Indonesia. Supervised by SUHENDI IRAWAN. The Mazak HCN 4000 II machine at PT Pindad Enjiniring Indonesia is a critical machine in the production of poros perata. Therefore, the reliability of the machine must be factor that is focused on being maintained. But in reality there is still fluctuating downtime. This research aims to assess how reliable the Mazak HCN 4000 II machine by calculating Overall Equipment Effectiveness (OEE), identifying the highest loss through the Six Big Losses. As finding the root cause of the problem and determining the improvement using Fault Tree Analysis (FTA). The result of the Mazak HCN 4000 II machine performance analysis research in the period June to November 2024 show an OEE value of 61% which consists of an availability value of 92%, a performance value of 66%, and a quality yield of 99%. The Six Big Losses that make the highest contribution to the decrease in engine reliability is idling minor stoppage of 31.90%.
