Abstract

Efficient warehouse layout management is a crucial factor in supporting smooth logistics operations. The Temporary Storage Warehouse (TPS) of PT XYZ currently applies a random storage system, resulting in high material handling distances, increased operational costs, and low space utilization. This study aims to redesign the warehouse layout using the class-based storage method combined with a block stacking system based on ABC analysis. The research method used is descriptive quantitative, with data collected through observation and interviews. The results show that the proposed layout reduces the material handling distance from 206,492 m/year to 147,970 m/year and decreases material handling costs from IDR 2,477,904 to IDR 1,775,640, achieving an efficiency of 28.34%. In addition, storage capacity increases from 250–300 packages to 400 packages. Therefore, the proposed warehouse layout design is proven to be more optimal in improving warehouse operational efficiency.

Abstract

Administrative activities at PT XYZ’s warehouse are still performed manually, such as recording and verifying physical documents, which leads to delays, data duplication, and operational inefficiencies. This situation indicates the presence of administrative waste that slows down warehouse operations. This study aims to identify and analyze this administrative waste in order to improve work process efficiency. The approach used was a qualitative descriptive method through direct observation of goods receipt and issuance activities, with analysis using Root Cause Analysis (RCA) and the 5 Whys Analysis to identify the root causes of the problems. The results of the study indicate that waste occurs due to the lack of an integrated digital administrative system and the low technological proficiency of employees. Therefore, it is recommended that administrative processes be digitized and that digital skills training be provided to create more efficient work processes.

Abstract

Managing high volume product flows at Warehouse Telkomsel Bandung faces challenges due to uneven workloads, as demand forecasting has not yet been implemented to account for potential inventory levels in the coming period. Using a descriptive quantitative approach and 5 Why’s analysis, this study further examined historical data compiled by the company over an 18 weeks period. As a result, Single Exponential Smoothing (SES) method was selected as the best method because it has the lowest error rate and controlled validation results. It is recommended that the company implement thi SES method and update the data periodically to maintain forecasting accuracy in the next period.
