Abstract
Industri lensa kacamata menghadapi tantangan dalam mempertahankan kualitas produk yang tinggi sambil tetap efisien dalam proses produksinya. Salah satu masalah utama yang dihadapi adalah tingginya tingkat defect partikel, yang dapat memengaruhi kualitas optik dan kepuasan pelanggan. PT. XYZ, sebagai produsen lensa kacamata terkemuka, mengalami tingkat defect partikel hingga 12% pada proses Line 1 UV Coater, yang berdampak signifikan terhadap biaya produksi dan efisiensi operasional. Untuk mengatasi masalah ini, penelitian ini menggunakan pendekatan Six Sigma dengan metode DMAIC (Define, Measure, Analyze, Improve, Control) guna mengurangi defect partikel dan meningkatkan kualitas produk. Pendekatan ini dimulai dengan mengukur Defects Per Million Opportunities (DPMO) dan tingkat Sigma sebelum dan setelah perbaikan, serta menganalisis faktor-faktor utama penyebab defect, seperti metode kerja, kondisi lingkungan, dan kinerja mesin. Hasil penelitian menunjukkan penurunan nilai DPMO dari 112.801 menjadi 46.782 dan peningkatan tingkat Sigma dari 2,71 menjadi 3,18, yang mencerminkan perbaikan signifikan dalam kualitas proses. Sebanyak 11 inisiatif perbaikan diterapkan, termasuk pemasangan Antistatic Blower dan optimalisasi sistem filtrasi, yang berhasil menurunkan tingkat defect dari 12% menjadi 4,7%. Penelitian ini membuktikan efektivitas Six Sigma dalam meningkatkan kualitas produk dan efisiensi proses produksi. Lebih dari itu, penerapan strategi ini berkontribusi pada pencapaian Sustainable Development Goals (SDGs), khususnya SDG 9 (Industri, Inovasi, dan Infrastruktur) dan SDG 12 (Konsumsi dan Produksi yang Bertanggung Jawab), melalui peningkatan efisiensi produksi dan pengurangan limbah industri. Dengan demikian, hasil penelitian ini memberikan wawasan strategis bagi PT. XYZ dan industri manufaktur secara keseluruhan dalam mengoptimalkan kualitas dan keberlanjutan operasional. The eyewear lens industry faces significant challenges in maintaining high product quality while ensuring efficient production processes. One of the primary issues encountered is the high level of particle defects, which can impact optical quality and customer satisfaction. PT. XYZ, a leading manufacturer of eyewear lenses, experienced a particle defect rate of up to 12% in the Line 1 UV Coater process, significantly affecting production costs and operational efficiency. To address this issue, this study utilized the Six Sigma approach with the DMAIC (Define, Measure, Analyze, Improve, Control) method to reduce particle defects and improve product quality. The approach began by measuring the Defects Per Million Opportunities (DPMO) and Sigma level before and after improvements, as well as analyzing the root causes of defects, including work methods, environmental conditions, and machine performance. The findings showed a reduction in DPMO from 112,801 to 46,782 and an increase in the Sigma level from 2.71 to 3.18, indicating a significant improvement in process quality. A total of 11 improvement initiatives were implemented, including the installation of Antistatic Blowers and optimization of the filtration system, which successfully reduced the defect rate from 12% to 4.7%. This study demonstrates the effectiveness of Six Sigma in enhancing product quality and production efficiency. Additionally, the implementation of this strategy contributes to the achievement of the Sustainable Development Goals (SDGs), particularly SDG 9 (Industry, Innovation, and Infrastructure) and SDG 12 (Responsible Consumption and Production), by improving production efficiency and reducing industrial waste. Consequently, the findings provide strategic insights for PT. XYZ and the manufacturing industry as a whole in optimizing quality and operational sustainability.
