Abstract

Inventory control is a crucial element in supporting the smooth production process in manufacturing companies. PT Bonecom Tricom, a producer of automotive spare parts, faces challenges in managing SPP-C05 Black plastic pellets due to inaccurate estimation methods, resulting in material accumulation in storage. This study aims to propose inventory planning using time series and min-max methods to optimize material requirements. The results show that the Holt-Winter's Multiplicative method provides the best forecasting accuracy with the lowest error rate (MAPE) of 2%. Furthermore, implementing the min-max method can reduce inventory costs by 14.245%. This study is expected to serve as a reference for companies to manage material inventory more effectively and efficiently.

Abstract

The development of the industrial sector has experienced significant acceleration due to the support of advancing technology and creative innovations from various companies. These innovations result from the collective contributions of all levels within a company's structure. This situation has intensified industrial competition, encouraging companies to continuously innovate in producing products that meet societal needs. Companies capable of creating high-quality products relevant to market demands have a greater chance of surviving and excelling in competition. For instance, between December 2023 and January 2024, a telecommunications company successfully produced 150,077,945 physical vouchers, with an average daily production of 2,543,694 units. During the production process, physical vouchers must meet specific criteria to ensure their quality. Quality control focuses not only on reducing product defect rates but also prioritizes customer satisfaction and loyalty. Six Sigma is one of the methodologies used to increase production process quality by reducing process variance and minimizing the number of defects in products or services. To facilitate the implementation of Six Sigma, the 5W+1H method can serve as a supplementary approach for problem identification and resolution. This technique involves systematically collecting information by answering the questions: What, Where, Who, When, Why, and How.
