Abstract
Tujuan penelitian kali ini Adalah untuk melakukan kajian sekaligus meminimalisasi defect rate pada rubber hose product pada salah satu manufacture rubber company. Yang melatarbelakangi study ini adalah peningkatan jumlah electric vehicle yang berpengaruh terhadap demand dari komponen kendaraan roda empat yang memiliki bakar bensin, termasuk produk rubber hose. Pendekatan yang digunakan dalam penelitian ini adalah metode Lean Six Sigma dengan tahapan Define, Measure, Analyze, Improve, dan Control (DMAIC) guna menelusuri faktor penyebab utama terjadinya cacat serta mengoptimalkan production process. Dari hasil awal analisis memperlihatkan defect rate mencapai rata-rata 1,3% dimana melampaui toleransi maksimum dari ketentuan perusahaan yang telah ditetapkan yaitu maksimum 1%. Melalui penerapan alat seperti diagram Fishbone Diagram, FMEA, SIPOC Diagram, dan pengujian antar variable yaitu defect rate, suhu akhir, dan suhu awal proses diketemukan terjadinya fluktuasi suhu di step mixing yang berpengaruh signifikan kepada peningkatan defect rate. Selain daripada itu, teridentifikasi adanya non value added activity pada production process. Aktualisasi perbaikan yang telah dikerjakan pada fase improve menurunkan defect rate yang cukup signifikan. Sigma level mengalami peningkatan dari 3,6 ke 3,8 sementara nilai DPMO dapat turun dari 19.287 menuju 9.990. Oleh karena itu pengaplikasian Lean Six Sigma dapat terbukti secara efektif untuk menekan tingkat defect, peningkatan kualitas produk, dan menjadi salah satu poin aktifitas berkelanjutan ditengah dinamika industri global di dunia otomotif. The purpose of this study is to examine and minimize the defect rate in rubber hose products at one of the rubber manufacturing companies. The background of this research stems from the increasing number of electric vehicles, which has influenced the demand for components used in gasoline-powered four-wheel vehicles, including rubber hose products. The approach employed in this study is the Lean Six Sigma methodology with the Define, Measure, Analyze, Improve, and Control (DMAIC) stages to identify the root causes of defects and optimize the production process. The initial analysis results showed that the defect rate reached an average of 1.3%, which exceeded the company’s maximum allowable tolerance of 1%. Through the implementation of tools such as the Fishbone Diagram, FMEA, SIPOC Diagram, and the correlation analysis among variables—defect rate, final temperature, and initial process temperature—it was found that temperature fluctuations in the mixing step significantly affected the increase in the defect rate. Furthermore, non–value-added activities were identified in the production process. The improvement phase resulted in a significant reduction in the defect rate. The sigma level increased from 3.6 to 3.8 while the DPMO value decreased from 19,287 to 9,990. Therefore, the application of Lean Six Sigma proved to be effective in reducing defects, improving product quality, and serving as one of the continuous improvement activities amid the dynamics of the global automotive industry.
