Abstract

This study aims to analyze and improve the quality control of packaging printing production at PT XYZ by applying the Lean Six Sigma methodology. Lean Six Sigma combines waste reduction principles with statistical quality control to achieve operational excellence. The research identifies major production challenges, including high defect rates, overproduction, and ineffective inventory management, all of which contribute to increased costs and reduced efficiency. The DMAIC framework—Define, Measure, Analyze, Improve, and Control—was employed to systematically address these issues. During the Define and Measure phases, types of waste were identified and defect rates were calculated using Defects Per Million Opportunities (DPMO). In the Analyze phase, root causes were examined using a Fishbone (Ishikawa) diagram, highlighting factors related to manpower, materials, machines, and methods. The analysis revealed a sigma level of 3.2, indicating a moderate level of process quality and substantial room for improvement. To address the identified issues, several improvement strategies were proposed. These include implementing a Just-In-Time (JIT) system to reduce inventory waste, adopting the First-In-First-Out (FIFO) inventory method for better material rotation, and conducting targeted technical training for operators to minimize human error. In the Control phase, the study suggests process standardization, routine inspections, and continuous monitoring as key practices to ensure that improvements are sustained over time. The findings and recommendations from this study are expected to contribute to better quality control, reduced operational waste, and enhanced productivity in the packaging printing process. Ultimately, this approach aims to strengthen PT XYZ’s competitiveness in the printing industry by fostering a culture of continuous improvement and quality excellence.

Abstract

PT CAM memproduksi AMDK galon Alexa 19 L dan mengalami hambatan produksi ketika ketersediaan bahan baku tidak mencukupi. Penelitian ini bertujuan menyusun perencanaan kebutuhan dan pengendalian persediaan untuk dua bahan baku utama, yaitu tutup galon dan seal galon, pada periode Januari 2023–Desember 2024. Metode yang digunakan adalah pendekatan kuantitatif dengan menyusun dasar kebutuhan melalui peramalan permintaan berbasis data penjualan historis 24 periode, kemudian menerapkan teknik lot sizing EOQ dan LFL sebagai alternatif kebijakan pemesanan. Model peramalan yang dipilih adalah DES α=0,1 karena memberikan nilai error terkecil pada dua metrik utama, yakni MAD dan MSE. Hasil menunjukkan total biaya persediaan metode perusahaan sebesar Rp 8.256.071, sementara EOQ menurunkan biaya menjadi Rp 4.407.902 (hemat 46,61%) dan LFL menjadi Rp 2.979.379 (hemat 63,91%). Dengan demikian, LFL menjadi opsi biaya terendah, sedangkan EOQ relevan bila perusahaan membutuhkan pola pemesanan yang lebih stabil.
