Abstract

Seiringnya dengan perkembangan bisnis di Indonesia, beberapa industri manufaktur di Indonesia mengantisipasinya dengan adanya kreatiftas dan inovasi. Setiap perusahaan dituntut untuk menerapkan beberapa pemodelan dalam melakukan perbaikan sistem. Permasalahan yang sering terjadi diantaranya: beberapa industri manufaktur di Indonesia mengantisipasinya dengan adanya kreatiftas dan inovasi. Masalah yang sering terjadi di perusahaan adalah waktu henti pada setiap line produk dan mengakibatkan target produksi tidak tercapai, sehingga mempengaruhi pengiriman produk ke pelanggan. Penelitian ini bertujuan untuk membuat sistem pemodelan yang diharapkan dapat meningkatkan produktifitas kinerja, sehingga target produksi dapat tercapai dan pengiriman produk ke pelanggan tidak terganggu. Penelitian ini menggunakan metode Soft System Methodology (SSM) dalam menganalisa dan melakukan perbaikan. Hasil dalam penelitian ini berupa sistem pemodelan dalam perbaikan dengan 6 tahapan atau langkah perbaikan diantaranya identifikasi masalah, causal loop diagram ketidakefektifan mesin, rich picture ketidakefektifan mesin, root definitions, model konseptual peningkatan produktivitas perusahaan, dan proses debating.

Abstract

The current era provides challenges for several automotive industries to be able to compete and maintain the quality of their products. For four-wheeled auto­motive companies, satisfying customers regarding the visual appear­ance of the vehicle body is very important. However, internally, automotive companies still found many defects or failures in painting, amounting to 32.6%. Apart from that, rework also results in additional costs that the company must incur during the painting process. This study aims to clarify types of painting defects, analyze root causes, provide solutions, improve process capabilities, and in­crease the sigma level in the painting process in the four-wheeled vehicle industry. This study uses the Lean Six Sigma method, which is integrated into the DMAIC approach and other improve­ment tools. As a result, this study clarifies four critical defects in the orange peel defects of the painting section, craters, melting, and blur. This study has resulted in several corrective action solutions, including tightening supervision of the performance of painting section operators so that they are consistent and committed to working according to the Standard Operational Procedure (SOP) or work instructions that have been created. A competency matrix is used to evaluate operator performance, which is reported to super­iors and subordinates by the supervisory depart­ment. After carrying out corrective action, this study increased the process capability from 1.17 to 1.92. The higher the capability value, the higher the sigma level. This study also has increased the sigma level from 2.76 to 3.42, meaning an increase of 78%. .
