<![CDATA[UD. XYZ is one of the trading businesses that produces shoes with a simple working system. The production process is still dominated by activities that take a considerable amount of time due to the lack of standardized work and the high number of activities that do not directly add value to the product. This condition causes the total production time to be long and work efficiency to decrease. Therefore, this research aims to reduce cycle time and improve the efficiency of the shoe production process by identifying waste and applying Value Stream Mapping (VSM), Process Activity Mapping (PAM) methods, and implementing the 5S principles for improvement efforts. Based on the analysis results of the Current State Map and PAM, the total production time is 5,760 seconds, with most of it being necessary non-value added (NNVA) activities. After implementing improvement efforts using the 5S principles, the process and picking times, which previously took a long duration, were successfully reduced, resulting in a decrease in cycle time to 5,030 seconds, or an efficiency improvement of 12.6%. This result was achieved by adding supporting tools and machines and implementing improvements to the work system at UD. XYZ. Thus, the combination of the VSM method and the 5S principles proved effective as an improvement strategy for optimizing production performance.]]>

<![CDATA[Production process efficiency is a crucial factor for micro, small, and medium enterprises (MSMEs) in enhancing competitiveness within the food industry sector. However, many MSMEs still face obstacles such as non-value-added activities (waste), including waiting time and inefficient material handling. This research aims to analyze and improve the production process of soybean juice at SME XYZ using the Value Stream Mapping (VSM) and 5 Whys methods. The VSM method is used to map the value stream in the production process in order to identify value-added activities, non-value-added activities, and necessary non-value-added activities. Meanwhile, the 5 Whys method is used to find the root causes of waste occurring on the production floor. The analysis results show that the main waste occurs in waste transportation and waste motion due to inefficient production layout and the absence of standard operating procedures. After improvements were made using the U-shaped layout design, there was a decrease in Non-Value Added activity time from 4,468 seconds to 2,270 seconds, and a decrease in lead time from 10,848 seconds to 8,650 seconds. Thus, the application of the VSM and 5 Whys methods proved effective in improving process flow efficiency and reducing waste in the production of soybean milk at UMKM XYZ.]]>

<![CDATA[The competitiveness of the manufacturing industry demands companies to enhance production efficiency and reduce product defects. PT. Kerta Rajasa Raya, a woven bag manufacturing company, faces a high level of production scrap (defects), which decreases productivity and increases production costs. This study aims to analyze the defect rate, identify process waste using the Value Stream Mapping (VSM) approach, and determine the root causes of major defects through Root Cause Analysis (RCA). The research employs a descriptive case study method using secondary data from production and defect reports from January to June 2025. The results show that the total defect rate reached 3.44%, with the dominant defect being setting at 0.56% of total production. Based on the VSM mapping, the main wastes occur in the printing and cutting processes due to the absence of a standard operating procedure (SOP) for machine setting, long waiting times, and repeated rework. RCA analysis revealed that the root causes stem from insufficient operator training, machine wear, and variations in raw material quality. Improvement through the future state map, including the implementation of SOPs, kanban system, and operator training, led to a 52% improvement in process efficiency and a 50% reduction in defect rate. This study demonstrates that the integrated application of VSM and RCA is effective in identifying waste and improving production performance in manufacturing industries.]]>

<![CDATA[This study aims to examine how the application of the Poka-Yoke and Kanban methods can improve production process efficiency at PT. XYZ, a hypothetical shoe company simulated using dummy data. In this simulation, daily production capacity is set at 1,000 pairs of shoes with an initial defect rate of 5% and a Work in Process (WIP) quantity of 1,000 pairs. The results show that the implementation of Poka-Yoke, which serves to prevent human error during the production process, successfully reduced the defect rate to only 0.1% and saved approximately Rp 73,500,000 per month. Meanwhile, the implementation of Kanban, which focuses on controlling material flow and inventory efficiency, was able to reduce the number of WIP by 70% and generate savings of around Rp 210,000,000 per month. Financial analysis shows a Return on Investment (ROI) of 782% for Poka-Yoke and 4,940% for Kanban, meaning that both methods are highly profitable. When applied simultaneously, they also increase the number of finished products (throughput) by 18.75%. Overall, this study demonstrates that the combination of Poka-Yoke and Kanban can be an effective strategy for reducing waste, minimizing product defects, and improving productivity in the modern shoe industry.]]>

<![CDATA[This research was conducted at PT. YYY, a manufacturing company engaged in fabrication with a focus on the plate cutting process, which plays an important role in determining the accuracy, precision, and quality of production results. However, various problems were still found such as cutting defects, inappropriate dimensions, and deformation due to heat that caused rework and wasted time and costs. To overcome this, this study applied the Root Cause Analysis (RCA) and Value Stream Mapping (VSM) methods to identify the root causes of defects and non-value added activities (Non-Value Added). The results of the analysis showed a total of Non-Value Added (NVA) of 80 minutes and a waiting time of 130 minutes, with the main causes coming from the Man, Method, Machine, Environment, and System aspects. Through the implementation of improvements such as work standardization, measuring instrument calibration, area layout arrangement, and digitalization of the material monitoring system, increased efficiency, reduced waste, and improved overall production quality and timeliness were achieved.]]>

<![CDATA[PT. XYZ is a company engaged in the furniture industry, with one of its main products being wooden doors, which serve as the object of analysis in this final project. Based on historical data from June 2025 to October 2025, there is a gap between the actual production output and the company’s target. This shortfall is indicated to be caused by waste occurring throughout the production process. Through the lean manufacturing approach, the types and causes of waste were identified using Value Stream Mapping (VSM) and Process Activity Mapping (PAM). The mapping results show a total production lead time of 4,320 seconds and reveal the presence of Non-Value-Added (NVA) activities that affect production performance. The waste with the highest percentage is motion waste, accounting for 66%, which becomes the focus of this study. The root causes of motion waste were analyzed using the 5 Whys method to determine the source of activities that do not add value. Based on the results of this analysis, improvement plans were developed through the implementation of 5S activities (seiri, seiton, seiso, seiketsu, and shitsuke) to minimize motion waste. The implementation of the proposed improvements shows that the total lead time has the potential to decrease and can be further enhanced through continuous kaizen efforts.]]>
