Abstract

Keterlambatan adalah suatu permasalahan yang sering terjadi di dunia industri. Keterlambatan yang dimaksud dalam hal ini yaitu keterlambatan terselesaikannya suatu proses produksi sesuai dengan tanggal deadline yang telah ditentukan dan disepakati kedua belah pihak. Dalam penelitian ini metode yang digunakan untuk mengatasi masalah keterlambatan yaitu Metode Lean Six Sigma. Tujuan dari penelitian ini yaitu mengatasi masalah keterlambatan dengan mengidentifikasi serta menganalisa jenis – jenis pemborosan atau waste yang terjadi selama proses produksi berlangsung. Adapun yang akan dijadikan objek penelitian ini adalah mould inhaler barrel. Output yang akan dihasilkan dari penelitian ini yaitu dengan memberikan usulan perbaikan terhadap perusahaan sebagai pertimbangan dalam menentukan kebijakan untuk mengatasi permasalahan yang berkaitan dengan keterlambatan yang terjadi pada saat proses produksi berlangsung. Dari hasil penelitan yang dilakukan dengan menggunakan beberapa cara untuk mengidentifikasi waste didapatkan hasil bahwa waste waiting adalah waste kritis dalam proses produksi mould inhaler barrel. Dibuktikan dengan hasil pembuatan diagram VSM yang diketahui terdapat kegiatan menunggu sebelum ke proses Milling, kemudian dengan pengelompokkan VA dan NVA didapatkan hasil NVA sebesar 27,24% dengan total waktu sebanyak 947,13 menit dalam satu kali proses produksi sedangkan dalam metode pembobotan kuesioner diketahui yang menjadi peringkat pertama yaitu waste waiting. Dengan menggunakan metode fishbone diagram didapatkan 5 faktor penyebab terjadinya waste waiting yaitu faktor manusia, faktor metode kerja, faktor mesin, faktor bahan baku, dan faktor lingkungan kerja. Usulan perbaikan yang didapatkan dari penelitian ini salah satunya membuat kontrak kerja mengenai keterlambatan pengiriman raw material ke perusahaan dari suplier, menjadi usulan perbaikan yang berdasarkan perhitungan peringkat RPN merupakan permasalahan yang harus segera dilakukan perbaikan.

Abstract

PT. Berlina Tbk Pandaan is a plastic packaging and mold maker company with a make to order production system especially at the Mold Shop Department with job shop production flow. From the scheduling system, production delays often occur. Injection Mold Base for Tumbler Upper Cap products was chosen as the object of research with a delay of 7 weeks. The purpose of this study is to determine the sequence of job operations flow by minimizing tardiness and makespan using the Genetic Algorithm method so as to produce optimum scheduling. The analysis of this study involved 37 jobs with 24 different machines. Calculations on the Genetic Algorithm method using Microsoft Excel and MATLAB R2012b media. From the calculation of the Genetic Algorithm method produces tardiness value of 0 hours, makespan 134.125 hours, and the highest fitness value of 2.3126. While scheduling the company produces a value of tardiness of 589.8750 hours and makespan of 195.125 hours. Then this method is able to minimize 100% tardiness and 31% makespan of company scheduling. While the operating flow of the resulting job is: 25-14-11-26-6-18-23-36-31-5-4-1-13-33- 8-35-32-12-34-7-3- 28-17-15-29-2-22-27-9-30-19-21-37-16-24-20-10.

Abstract

A construction company in Karangpilang received a Pressure Vessel project. This project is delayed from the predetermined date so that a fine of 0.2% is imposed every day. So it is necessary to analyze project scheduling in order to get the maximum time and cost in this project. The methods used in this research are Time Cost Trade Off (TCTO), Precedence Diagram Method (PDM) and crashing. Acceleration is carried out on critical trajectories namely Marking/Catting, Rolling, Fit-Up, Welding, NDT, Primary Blasting and Top Coat. This study uses alternatives to increase over time and additional manpower. In this study, the maximum time and cost results were obtained with an alternative of 25% additional manpower. The resulting accelerated duration is 51 days faster than the actual duration, with costs incurred of Rp. 199,616,473, -, resulting in a decrease of 70% from the actual duration cost of Rp. 286,961,745, -. S curve analysis shows that the accelerated duration can be completed faster than the actual duration because the project can be completed on December 27, 2021. Where the accelerated duration is closer to the planned duration, namely November 26, 2021.
