Abstract

In Indonesia, there are already many established companies. Starting from a more focused industry/manufacturing, services, and trade. Many companies are starting to look for ways to increase the company's profits. The manufacturing industry sector itself certainly spends a lot on production. Therefore, the company is looking for a method that can minimize production costs. The purpose of this study is to minimize production costs. The method used is the aggregate chase strategy method. The results showed that planning using the aggregate chase strategy method can minimize production costs. After comparing the company's total production cost in 2020 amounted to Rp. 8,952,896,124 with the results of planning using the aggregate method of chase strategy in 2021 amounting to Rp. 8,428,458,444, obtained a gap of Rp. 524,437,680. By planning production costs using the aggregate method, the company can reduce the amount of labor and utilize the amount of labor available as much as possible without incurring workers' overtime costs. Then the company can save on production costs.

Abstract

Quality control is essential to ensure that products meet predetermined specifications and align with company policies. Based on PT XYZ’s production report from December 2023, the number of defective products requiring repairs was notably high, reaching 17.3% of the total 98,852 gas cylinders produced within 19 days. This study aims to evaluate the quality control performance and identify the factors influencing it. The Six Sigma DMAIC method was applied to assess performance. At the measurement stage, the Defects Per Million Opportunities (DPMO) was found to be 44,743, corresponding to a sigma value 3.203. The study identified four key factors contributing to production defects: machinery, materials, personnel, and methods. Although the company's quality control efficiency is deemed satisfactory, it has yet to prevent a significant sales decline of 20-40%. Therefore, implementing Six Sigma analysis is expected to uncover processes that can reduce manufacturing defects in 3 kg LPG cylinder production. By addressing these issues, the company can improve product quality, maintain customer satisfaction, and enhance competitiveness in the market.
