Abstract

The problem that occurs at PT SUGIYAMA Indonesia is that there are many defects in the inner and outer areas. Defects occur during the process stage or cutting, rolling. So that when the material has reached the visual inspection stage, many types of NG (Not Good) occur, including NG (Not Good) which often occurs based on NG (Not Good) recap data in the last three months of 2024 is NG (Not Good) Dent. Based on the data listed, the percentage of NG (Not Good) Dent increases every month, and the highest defect rate is around 33k pcs of the total NG (Not Good) of the overall model. Therefore, a case study study was conducted using the QCC (Quality Control Circle) method to analyze the occurrence of the defect, and aimed to reduce the number of NG (Not Good) Dent and make the production process better. Based on the data from the research results, the researcher succeeded in reducing NG (Not Good) Dent based on data from the last three months, which had reached 100%, after observations and using the QCC method and its auxiliary tools, namely the cause-and-effect diagram (Fishbone) and the pareto diagram, the percentage in the next two months from November to December 2024, only reached 37%.

Abstract

Emsonic Indonesia is a company engaged in plastic mold manufacturing, which produces speakers in the form of units, case assemblies, and finished forms based on RPP (Product Delivery Plan). PT. Emsonic Indonesia strives to provide the best for customers, by improving product quality. This study aims to analyze the causes of product defects, use the Fish Bone diagram method to analyze the causes, and apply Total Quality Management (TQM) to improve product quality at PT. Emsonic Indonesia. Based on the results of the fish bone diagram method, it can be seen that product defects come from human, mechanical, method, management, material, and environmental factors. In the human factor, it was found that employees did not receive adequate training regarding the operation of machines and correct work procedures giving rise to NG products because they exceeded the limits of inspection standards. Meanwhile, based on Total Quality Management (TQM), it was able to explain the improvement of product quality by 51.3% while the remaining 48.7% was explained by other factors that were not studied in this study. Meanwhile, the results of the F test show that simultaneously the variables of the production process and Total Quality Management (TQM) simultaneously have a positive and significant effect on the improvement of product quality and the results of the t test show that the variables of the production process and Total Quality Management (TQM) have a positive and significant effect on the improvement of product quality at PT. Emsonic Indonesia.

Abstract

PT QWERTY always strives to maintain production quality and quantity by paying attention to the performance of all employees, especially production operators. However, during the production process, NG / Abnormal is still often found, production targets are not achieved, and NG products are sent to customers (Customer Claims). This happens because human error such as employee performance that does not comply with SOPs, working in a hurry, and even in some cases, employees are sleepy, especially when working the night shift, are also the cause. This study aims to analyze the performance of operators who do not work in accordance with the Standard Operating Procedure (SOP) in the production process. This study uses the 5W + 1H method. The 5W+1H method is an information gathering and analysis technique that includes six basic questions, namely What, Who, When, Where, Why, and How. The results of the analysis show that violations of SOPs by operators can trigger errors in the production process, leading to NG products being delivered to customers. The main factors that trigger non-compliance with SOPs include lack of training, high workload, and lack of regular monitoring and evaluation of performance.

Abstract

When businesses do batching for products that have varying levels of demand, work will usually be distributed unevenly, creating a high probability of overtime or idle time on the production line. These peaks and valleys in production result in an overload for workers. On one hand when demand skyrockets, and lower productivity on the other hand when demand plummets to its lowest point. There is an imbalance in the production process, so it is necessary to equalize what we know as Heijunka. So, heijunka means conversion to a production level. The definition indicates that the production run on the workstation or factory floor is production leveling or production leveling. Consumer demand is broken down into smaller lot or batch sizes. The applied production schedule spreads the production demand more evenly (demand leveling) in turn among all product items, so production is relatively stationary (production leveling). This avoids the buildup of products that are continuously produced for a long time, and long lead times for other products that are not produced. Waste due to stock accumulation and waiting time can be prevented by heijunka. Based on the research data using qualitative methods with interviews, significant analysis results were obtained, namely that before using the Heijunka method, there was a buildup in the first hour of 37 units, while in the second hour there were only 13 units. However, when using the Heijunka method, it was successfully averaged to 25 units per hour for 8 working hours, so that the total production time reached 480 minutes. With this method, production time equalization is achieved so that there are no unit models that are produced independently at the end of production, this also minimizes delays in customer requests if there are product order variables.

Abstract

This research aims to improve the quality of the production process on the Pipe Bender machine at PT XYZ through the integration of Failure Mode and Effect Analysis (FMEA) in the Quality Control Circle (QCC). The initial analysis identified a major problem in the form of damage to the wiper components that caused the product defect. The main causes include materials that are too hard, lack of spare stock, and the absence of standard wiper radius specifications. The solutions implemented include changes in the technical specifications of wipers, the manufacture of stock control systems, and the standardization of production processes. The results of the evaluation showed a 50% reduction in the frequency of damage, from a total of 17 problems to 8 problems, and an increase in production efficiency. The QCC-based approach has proven to be effective in improving the performance of the production process in a sustainable manner.

Abstract

This research was conducted at PT. XYZ, a metal stamping company, to identify and mitigate dimension out problems. The research took place from August to October and used problem-solving methods such as Root Cause Analysis (RCA), Statistical Process Control (SPC), Fishbone Diagram, and Failure Modes and Effects Analysis (FMEA). The main problems identified were the inconsistency of operators in working and the frequent fluctuations of the machines used, which had a significant impact on the final production output. The SPC method is used to monitor process variations and identify deviation patterns. Fishbone Diagram helps in identifying the underlying causative factors of this problem, while RCA is used to dig deeper into the root causes. FMEA is applied to assess the risks associated with these variations and determine the priority of corrective actions. The results of the analysis show that variations in operator performance and engine turnover are often the main factors causing dimensional problems. Corrective measures implemented include operator retraining to improve work consistency, implementation of stricter standard procedures, and machine maintenance schedules to reduce the frequency of engine changes. The implementation of this action has succeeded in significantly reducing the frequency of dimension out and increasing the stability of the production process. This study concludes that the use of a structured and comprehensive approach in identifying and overcoming dimension out problems can improve product quality and production efficiency at PT. XYZ. Recommendations for continuous improvement are also recommended to ensure that the process remains stable in the long term and from the data collected, it can be seen that the largest contributor rejection is dimension out, namely the size of the product exceeding the specifications. If this size excess is too large to exceed the existing tolerances, it will greatly affect the yield in the assembly process. If found in customers , it will have a fatal effect on customer trust in the quality of the products produced. This can have an impact on the company's business interests.
