Abstract

PT Federal Superior Chain Manufacturing is a motorcycle chains manufacturing company. PT Federal Superior Chain has a problem with the finishing line of drive chain OEM AHM. The finishing work station’s time is imbalance. It makes bottleneck between work station in finishing line. The purpose of this paper is to balance the finishing line of drive chain OEM AHM and reduce bottleneck between workstation in finishing line. The method used is Line balancing Methods and Time Measurement Methods. These improvements increase line efficiency, which was originally only 50.81% to 64.3%. These improvements also reduce cycle time on the finishing line from 4059.27 seconds to 3215.98 seconds. The capacity of drive chain increase from 463.40 lot to 466.50 lot Keywords: bottleneck, efficiency, methods time measurement, line balancing, cycle time

Abstract

 Competition in this globalization era has led manufacturing enterprises improving their production andservices by enhancing the engine utility and accuracy in the production completion to meet the schedule set. PT. XYZ is a company engaged in the automotive industry, especially in the field of stamping parts or four-wheeled vehiclescomponents. The purpose of this study is to minimize the processing time (makespan) of the ISUZU stamping parts production process in the Line B of PT. XYZ. The proposed scheduling method consists of two: Campbell, Dudek, and Smith (CDS) and Nawaz, Enscore and Ham (NEH). CDS Methods combine machines sorted from the smallest to the largest based on the Johnsons rule. NEH heuristic sorted the job in two different sequences (J1-J2 and J2-J1), selected the smallest makespan and carried it on until the n jobs. The two methods applied resulted in different job sequences to be compared with the scheduling applied in the company. NEH method is a method with the best makespan time which is 4,858 minutes. It can save 252 minutes of scheduling makespan from the original schedule of 5,110 minutes. Keywords:             scheduling the series, the method of Campbell, Dudek and Smith (CDS), the method Nawaz, Enscore and Ham (NEH), makespan

Abstract

ABSTRAKLine H pada PT. XYZ Press Production di perusahaan manufaktur otomotif menggunakan mesin press semi otomatis yang bekerja dua shift per hari. Oleh karena itu, mesin harus dijaga agar ketersediaan dan performanya tetap terjaga, serta kualitas dan kuantitas produksinya. Makalah ini bertujuan untuk menganalisis departemen perawatan mesin dengan menggunakan Root Cause Analysis (RCA), Overall Equipment Effectiveness (OEE), dan HIRAC. Dalam penelitian ini RCA digunakan sebagai alat analisis atau metode pemecahan masalah untuk mengidentifikasi akar penyebab dari kesalahan atau masalah. Dari hasil analisis, PT. XYZ menggunakan lembar catatan penghentian jalur sebagai alat untuk mengidentifikasi akar penyebab penghentian jalur yang terjadi di setiap jalur produksi. Lini produksi kritis adalah Line H. Kemudian, ditentukan ketersediaan, kinerja, dan kualitas mulai bulan Agustus 2018 hingga Januari 2019 di Line H untuk mendapatkan OEE. Bulan Oktober 2018 memiliki Overall Equipment Effectiveness (OEE) terendah di antara periode lainnya. Juga, kami menganalisis HIRAC pada PT. XYZ menggunakan WRAS (Work Risk Assessment Sheet). Hasil analisis data menunjukkan bahwa perusahaan harus melakukan pemeliharaan preventif secara konsisten untuk mengurangi penghentian jalur di Line H. Kata kunci: Analisis Akar Penyebab; Efektivitas Peralatan Keseluruhan; HIRAC; perawatan mesin.ABSTRACT Line H at PT. XYZ Press Production in automotive manufacturing company used semi-automated press machines which work for two shift per day. Therefore, the machines should be maintained to keep the availability and performance of the machines, also to keep the quality and quantity of production. The aim of this paper is to analyze the machine maintenance department that are using Root Cause Analysis (RCA), Overall Equipment Effectiveness (OEE), and HIRAC. In this research, RCA is used as an analysis tool or method of problem solving, used for identifying the root causes of faults or problems. From the analysis, PT. XYZ used line stop record sheet as the tool for identifying the root causes of line stops that happened in every production lines. The critical production line is Line H. Then, determined the availability, performance and quality start from August 2018 to January 2019 in Line H to get OEE. October 2018 has the lowest OEE (Overall Equipment Effectiveness) among the other period. Also, we analyze HIRAC. PT. XYZ used WRAS (Work Risk Assessment Sheet). The results of data analysis show that the company should do the preventive maintenance consistently to reduce line stops in Line H
