Abstract

Efektivitas mesin produksi merupakan faktor utama dalam meningkatkan produktivitas di sektor manufaktur. Penelitian ini bertujuan untuk menganalisis dan meningkatkan efektivitas mesin produksi Hollow di PT Sermani Steel Corporation melalui penerapan metode Overall Equipment Effectiveness (OEE) dan Fault Tree Analysis (FTA). Analisis dilakukan terhadap kinerja mesin sebelum dan sesudah implementasi perbaikan, serta identifikasi akar penyebab kegagalan menggunakan FTA. Hasil penelitian menunjukkan bahwa nilai OEE masing-masing sebesar 84% (Maret), 81% (April), 79% (Mei), dan Juni 2024 tetap stagnan pada angka tersebut. Analisis FTA mengidentifikasi penyebab utama penurunan efektivitas, termasuk pelatihan operator yang tidak memadai, kurangnya inspeksi rutin, ketidakkonsistenan ketebalan bahan baku, pisau pemotong yang tumpul, kebersihan lingkungan yang buruk, serta frekuensi pembersihan yang rendah. Penelitian ini menyimpulkan bahwa penerapan metode OEE dan FTA belum mampu meningkatkan efektivitas mesin produksi Hollow secara signifikan.

Abstract

This study aims to regulate the production schedule to reduce product makespan caused by increasing demand. This study using the Nawaz Enscore Ham method to minimize makespan on the production schedule at the Maros Futry Bakery and Cake Shop is very relevant and important. The results of this study are obtained from job sequences from the NEH method are J3-J2-J1 with a makespan time of 2.72 hours Based on the analysis and discussion, the conclusion of this study is the sequence of work in the futry bakery and cake shop obtained by the nawaz enscore ham method, namely J3-J2-J1 or on the product bolu mabel – bolu rempah – maros bread obtained during makespan which is 9827.84 seconds or 163.79 minutes or equal to 2.72 hours. So that it can reduce the buildup of demand with an increasingly fast time compared to the company's makespan time, which is 7.18 hours.
