Abstract

A slow and inefficient inbound process is a major challenge in the warehouse operations of PT DE, a company in the FMCG sector. This study aims to optimize the inbound process through the implementation of Lean Logistics. The method used is a quantitative approach by combining Lean Six Sigma through the DMAIC cycle and Kaizen principles through the PDCA cycle. Observations show that most inbound activities fall under Necessary Non-Value Added (NNVA), such as manual inspections, data entry, and documentation, accounting for up to 93% of the total process duration. Root cause analysis was carried out using Value Stream Mapping and Fishbone Diagram. Improvement solutions include implementing barcode/RFID technology, automated conveyors, employee training, and standardized procedures. After implementation, there was a significant increase in the speed and accuracy of goods receipt. Control was maintained through regular audits and a digital monitoring system. The application of Lean Logistics proved effective in reducing waste, increasing efficiency, and supporting continuous improvement in the FMCG warehouse environment

Abstract

The Production System Laboratory at Politeknik ATI Makassar has a practical module that utilizes wood as raw material, necessitating supporting facilities such as a safe and ergonomic cutting table. The current cutting table is rudimentary, consisting of a table with a hole in the middle to accommodate the cutting machine blade. Although this setup facilitates the cutting process, it lacks protective or safety features, increasing the risk of workplace accidents. Additionally, the absence of a measuring tool on the table leads to inaccuracies in product dimensions, often resulting in student projects failing to meet the required specifications. To address these issues, the laboratory has acquired a new cutting machine. However, this machine does not come with a suitable table for its placement. Therefore, this study aims to design and develop a cutting table that enhances workplace safety while incorporating a precise measurement system. The Theory of Inventive Problem Solving (TRIZ) method is employed to identify problems and develop an optimal cutting table design. The findings indicate that the proposed cutting table design meets the requirements of the practical module and is expected to reduce the risk of workplace accidents while improving cutting accuracy

Abstract

Along with the development of the increasingly competitive coffee industry, coffee shops must have a business strategy in managing good coffee supplies to increase competitiveness. Time series forecasting is one of the ways that Koromi Sip & Slurp can use because it serves as a basis for company decision making to develop business strategies. This study aims to determine the best time series forecasting method that can be used as a basis for determining business strategies in managing coffee supplies. The data used is weekly sales data of three types of coffee beans from August 2024 to February 2025. The time series forecasting methods used are Single Moving Average (SMA), Weighted Moving Average (WMA), and Single Exponential Smoothing (SES). Evaluation of the method is carried out based on the forecast error value using the MFE, MAD, MSE, and MAPE methods. The results of the analysis show that the SES method provides the smallest error rate for all types of coffee so it was chosen as the best method. Validation using the Moving Range Chart shows that the forecasting results are within the statistical control limits. Forecasting for the 31st period resulted in a total demand for Sweet Coffee 322 cups, Non-Sweet Coffee 72 cups, and Manual Brew 8 cups. The resulting forecasting is expected to be used as a basis for strategic decision making, one of which is the management of coffee inventory at Koromi Sip & Slurp

Abstract

J&T Express Sumbawa began operations in 2016. Based on the results of a questionnaire containing 10 questions to 20 customers, it was found that JNE was the preferred choice of consumers when selecting a freight forwarding service. This indicates that consumer interest in choosing J&T Express Sumbawa for shipping services has decreased. The method used to design J&T Express Sumbawa's competitive strategy involved analyzing the internal and external environment through the determination of IFAS weights, EFAS, the IE matrix position, and the formulation of strategies using SWOT analysis. For prioritizing alternative strategies, QSPM was used. The results of the IFAS matrix calculation yielded a total score of 2.913, and the EFAS matrix calculation yielded a total score of 3.524. The strategy from the IE matrix is described as a growth and development strategy. The SWOT matrix strategy produced 11 alternatives: 2 SO strategies, 3 ST strategies, 3 WO strategies, and 3 WT strategies. The QSPM matrix strategy priority assessment yielded 3 main priorities: strategy 5 with a TAS score of 5.692, which involves implementing technology to improve service quality; strategy 2 with a TAS score of 5.594; and strategy 10 with a TAS score of 5.328

Abstract

At the Liquefied Petroleum Gas Filling and Transportation Station (SPBE), trolleys serve as an essential means of transport for moving LPG cylinders. These trolleys play a crucial role in facilitating the handling and movement of cylinders throughout the operational process—from the filling station to the distribution area. However, conventional industrial trolley designs typically use heavy metal materials, which lead to several issues affecting operational efficiency and worker well-being. This study aims to redesign the industrial trolley used at SPBE stations by focusing on the use of lighter materials without compromising mechanical strength. The Weighted Properties Analysis (WPA) method was employed to evaluate various materials based on criteria such as tensile strength, corrosion resistance, lightweight characteristics, cost, and availability. The analysis results indicate that Carbon Fiber Reinforced Polymer (CFRP) is the most suitable material, offering advantages in low weight, high tensile strength, and excellent corrosion resistance. Furthermore, anthropometric data of workers were integrated into the design process to ensure an ergonomic and comfortable trolley that minimizes the risk of injury. The implementation of the proposed trolley design is expected to enhance operational efficiency, reduce workers’ physical load, and support environmental sustainability through the use of durable materials.
