Perancangan Stasiun Kerja Untuk Meningkatkan Efisiensi Proses Produksi Tas Dengan Menggunakan Metode Line Balancing

Introduction

Perancangan stasiun kerja untuk meningkatkan efisiensi proses produksi tas dengan menggunakan metode line balancing. Atasi bottleneck & waktu tunggu produksi tas. Rancangan stasiun kerja pakai Line Balancing (Region Approach) tingkatkan efisiensi 92%, optimalkan output produksi.

Abstract

Penelitian ini dilatarbelakangi permasalahan adanya waktu tunggu yang lama pada proses produksi. Hal ini disebabkan karena adanya aliran proses yang mengalami bottleneck pada stasiun kerja tertentu. Tujuan penelitian ini adalah merancang urutan proses stasiun kerja untuk memperlancar aliran proses sehingga waktu tunggunya pendek dan output produksi optimal. Metode yang digunakan adalah metode Ranked Postional Weight (RPW), metode Mirror RPW, metode Largest Candidate Rules (LCR), metode J.Wagon dan metode Region Approach. Tahapan kerja metode Line Balancing yaitu membuat Precedence Diagram, Assembly Chart, Bill of Material, Operating Process Chart dan melakukan perancangan stasiun kerja. Berdasarkan pengolahan data maka di dapatkan bahwa metode Line Balancing yang terbaik yaitu metode Region Approach dengan hasil line efficency sebesar 92% dan smoothing index sebesar 434,28 detik. Semakin besarnya line efficiency maka akan semakin baik pula hasil perancangan stasiun kerja maupun semakin rendah smoothing index akan berpengaruh terhadap baiknya perancangan stasiun kerja tersebut.

Review

This study addresses a pertinent operational challenge within the manufacturing sector, specifically the problem of prolonged waiting times and bottlenecks in the bag production process. The authors clearly articulate their objective: to design an optimal workstation sequence using line balancing techniques to enhance process flow, reduce waiting times, and maximize production output. The research employs a comprehensive set of line balancing methods, including Ranked Positional Weight (RPW), Mirror RPW, Largest Candidate Rules (LCR), J.Wagon, and Region Approach. A key finding is the identification of the Region Approach method as the most effective, achieving a remarkable line efficiency of 92% and a smoothing index of 434.28 seconds. The methodological rigor exhibited in exploring and comparing multiple line balancing techniques is a significant strength of this research. By systematically evaluating various approaches, the study provides valuable comparative insights that can guide practitioners in selecting the most suitable method for similar production environments. The inclusion of foundational steps such as creating Precedence Diagrams, Assembly Charts, Bills of Material, and Operating Process Charts demonstrates a thorough and structured approach to process analysis and workstation design. The quantitative results, particularly the high line efficiency and the reduction in the smoothing index, strongly support the claim that the proposed workstation design effectively addresses the identified bottleneck issues and contributes to substantial improvements in production efficiency. While the abstract provides a compelling summary of the methodology and results, a deeper discussion in the full paper on the practical implementation considerations, such as the investment required for workstation redesign or potential training needs for operators, would further strengthen its industrial applicability. Additionally, exploring the sensitivity of the chosen method to variations in task times or production volume fluctuations could offer a more robust understanding of its long-term performance. Nevertheless, this research offers a valuable contribution to the field of operations management, providing a clear and effective framework for optimizing production lines in manufacturing settings, particularly for products like bags, and holds significant promise for improving productivity and resource utilization.
