Pengendalian Kualitas Terhadap Produk Defect Botol Admire 400 Ml dengan Metode DMAIC di PT Natamas Plast

Abstract

Kualitas berkaitan dengan kondisi fisik produk yang mampu memenuhi keinginan dan kebutuhan konsumen, kualitas juga menjadi tolak ukur dalam upaya peningkatan jumlah produksi, mutu dan keandalan suatu produk. Penelitian ini difokuskan pada pengendalian kualitas proses produksi Botol Admire 400 ml di PT Natamas Plast dengan menerapkan metode DMAIC (Define, Measure, Analyze, Improve, Control) dari Six Sigma. Jenis defect yang berkontribusi paling signifikan yaitu tebal tipis. Perhitungan Defect Per Million Opportunities (DPMO) sebesar 19.562,96 menghasilkan level sigma sebesar 3,56, yang mencerminkan kualitas proses masih berada pada rata-rata industri Indonesia. Analisis menggunakan diagram pareto dan fishbone mengindikasikan bahwa faktor penyebab utama berasal dari manusia (operator), mesin, metode kerja, material, pengukuran, dan lingkungan. Implementasi solusi berupa perawatan mesin berkala, pelatihan operator, dan penggunaan check sheet dalam proses kontrol terbukti efektif dalam menurunkan risiko Defect serta meningkatkan kestabilan proses produksi.

Quality is related to the physical condition of the product that is able to meet the wants and needs of consumers, quality is also a benchmark in efforts to increase the amount of production, quality and reliability of a product. This research is focused on controlling the quality of the Admire 400 ml bottle production process at PT Natamas Plast by applying the DMAIC (Define, Measure, Analyze, Improve, Control) method from Six Sigma. The type of defect that contributes most significantly is thin thickness. The calculation of Defect Per Million Opportunities (DPMO) of 19,562.96 results in a sigma level of 3.56, which reflects the quality of the process is still at the average of the Indonesian industry. Analysis using Pareto and fishbone diagrams indicated that the main causal factors came from humans (operators), machines, work methods, materials, measurements, and the environment. The implementation of solutions in the form of periodic machine maintenance, operator training, and the use of check sheets in the control process proved effective in reducing the risk of defects and improving the stability of the production process.
