Evaluation on Application of Queuing Theory On Payment System in the Supermarket “Saga” Padang Pariaman West Sumatra

A company in the oil and gas manufacturing industry produces gas pipe products using the Polyethylene model. During the period of January to June 2020, the company experienced a defect rate of 2% in the total production. This research utilized a descriptive method to analyze the production process in order to identify and eliminate the rejected products. The objective of this study was to achieve a decrease in defects below 2%. By applying the Six Sigma (DMAIC) method and conducting calculations and analysis, an improvement proposal was developed to address the defects found during the Radiography Test. The proposed solution involves providing specialized training for workers, implementing clear procedures and methods for work, and conducting training sessions to enhance operator skills and understanding of Standard Operating Procedures (SOPs). As a result of the proposed improvements, a comparison of cycle times was conducted. Prior to the implementation of the improvements, the cycle time was 390 minutes. However, after the implementation, the cycle time reduced significantly to approximately 245 minutes. Overall, the proposed improvements aim to reduce the defect rate below 2% and optimize the production process for gas pipe products with the Polyethylene model in the oil and gas manufacturing company.

“…Their improvements included developing work instructions for machine operators, determining optimal settings for conveyor machine speeds, conducting thorough checks on cartons to be used, creating clear work instructions for carton folding, procuring measuring instruments to aid machine setup, and providing guidance and supervision to ensure proper machine adjustment. Similarly, (33)(34) implemented the DMAIC method to reduce the rejection rate in the Plastic Painting Department. Their improvements involved manufacturing paint mixer machines and vacuum cleaners, performing maintenance at all stations, and implementing quality control measures for production paint materials (34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48).…”

Implementing Six Sigma in Filling Process of InjectionMedicine:A Case Studies in Healthcare Industry

Haekal¹

2023

The research focuses on a pharmaceutical company operating in the pharmaceutical and health-related products industry. The filling process for injection medicines has experienced a higher average rate of rejects, reaching 3.2% between September 2022 and February 2023, which exceeds the company's set limit of 2.0%. This study aims to identify the factors contributing to the problem and provide recommendations for reducing rejects using the DMAIC method. During the Define stage, SIPOC diagrams and CTQ identification are utilized. Three CTQ categories are identified: volume defects, imperfect sealing defects, and empty defects. The Measure phase, employing a Pareto diagram, highlights volume defects as the most prevalent. DPMO calculation using the rejected injection medicinepreparation data results in a value of 10630, with a sigma level of 3.80. The Analyze stage involves identifying the factors causing the problem through the use of a Fishbone Diagram. Furthermore, the highest RPN value of 112, indicating potential failure, is determined to be due to insufficient supervision during the production process according to FMEA. In the Improve stage, the 5W+1H tools are employed to generate appropriate improvement proposals. These proposals are documented, disseminated, and adopted as standard work guidelines.

“…Technology in a system must be immediately applied to manufacturing so that the system can continue to grow, especially systems in warehousing. A sound warehousing system is a warehousing system that can utilize space to store effectively to increase space utilities and minimize material handling costs [1][2][3][4][5][6][7].…”

Analysis of Barcode System Design and Checklist to Reduce the Lead Time of Delivery of Goods using FIFO Method at PT Indo food TBK Company of Indonesia

Hanum¹

2022

PT. Indofood, in carrying out goods storage and retrieval activities, is carried out without a barcode and checklist system. Without this system causes high lead times, referring to the time recorded by the SAT system. This system is used by management to control the loading/unloading movement of the company. Longer times often result in inefficiency and wasted resources, and companies should review their processing times against benchmarks to identify ways to improve their lead times. The purpose of this study is to provide improvement efforts to overcome delivery errors on finished goods, reduce the lead time of the delivery process with the kanban system through the FIFO method, and compare the difference in the lead time of the delivery process before and after the procedure. The author's research process in carrying out research from planning to carrying out research at a specific time. The analysis carried out is to evaluate the results of the delivery system improvement, search for goods to be sent based on the delivery plan, and the amount of time required to make deliveries based on the lead time displayed via SAT. The results showed that the kanban checklist design using the FIFO method could reduce problems in shipping in and out of products in the warehouse by reducing recording errors and accelerating the recording process quickly, precisely and accurately. The product process flow based on the kanban checklist system makes it easier for operators in the implementation process from incoming products to outgoing products. Item data will be entered automatically into the existing computer Kanban checklist using the FIFO method. The type of barcode used is a barcode that can input data in the form of letters, numbers and symbols. The company needs this type because the data inputted in the barcode uses these three forms.
