Abstract

This study analyses the quality of FR S/C Side RH Bracket products at PT BMI, especially concerning the nut dragging problem, which is often the main defect. This study aims to analyze and improve the nut dragging defect problem in FR S/C Side RH Bracket products, as well as provide an understanding of the effectiveness of the improvement in reducing the number of defective products. The analysis shows that FR S/C Side RH Bracket products with nut dragging problems are the most frequent defects, reaching 632 defective units or about 60% of the total defective products before improvement. The Failure Tree Analysis (FTA) method was used to identify the root cause of the nut dragging problem, which revealed that machine factors were generally the main cause, especially setting the spot welding machine parameters too high. In response, improvements were made by changing the parameters on the SW.03 spot welding machine and adding a cooling water line. The results showed a significant decrease in defective products, totaling 1320 units. After the improvement, only 141 units were defective. This research provides an in-depth understanding of product quality issues at PT BMI. It offers solutions to improve product quality and meet customer expectations in the highly competitive automotive industry.

Abstract

This study endeavors to enhance the productivity of solar module production in a renewable energy conversion company. The existing production line needs help in achieving the daily target of 64 units, resulting in an actual output of only 40 units. This study focuses on optimizing the production line by considering processing time adjustments and operator flexibility. To accurately measure working time, we incorporate operator flexibility and adjustment factors in the planning phase of solar module production. The primary objective is establishing an optimal production trajectory by balancing the load and capacity across workstations, thereby elevating overall production efficiency. The approach involves the application of the trial-error method and the shortest operation time method, implemented through POM QM software. Through meticulous data analysis, we determine that the trial-error process yields the most optimal results. Post-implementation, improvements are evident as the solar module production capacity increases to 60 units per day from the initial 40 units. Additionally, the idle time ratio on the assembly line to available time diminishes to 13.17% after optimization. This study contributes valuable insights into the effective enhancement of solar module production lines, emphasizing practical methodologies and software-assisted techniques for achieving substantial productivity gains in the renewable energy sector.

Abstract

One of the manufacturing companies in Indonesia which is engaged in foundry has a production line for various types of automotive components and has produced 2051 types of products. One of the products produced is the Trunion Bracket. In the molding process, cores are needed that can provide cavities in the product. The current production process has not been able to meet demand because the production cycle time does not match the predetermined time. This discrepancy will affect consumer satisfaction. Therefore, it is necessary to make a schedule for the period July to December 2022, to assist companies in facilitating the scheduling of the production process using Rough Cut Capacity Planning and System dynamics. The calculation results from Rough Cut Capacity Planning indicate that the 5th workstation experienced a shortage of production time from July to September 2022, so an additional number of working hours had to be made. The addition of the number of working hours before improvement was 367 hours and after improvement was 112 hours. Meanwhile, the results of system dynamics modeling for the period July to December 2022, require an additional working hour before improvement by 308 hours and 205 hours after improvement are carried out. The companies can implement strategies based on the results of system dynamics simulations to identify, forecast, and plan production capacity requirements for the next.

Abstract

The objective of this study is to employ a multi-criteria decision-making system technique to identify the most optimal supplier in the automotive components sector.   When selecting a supplier, it is crucial to evaluate the pros and downsides of each source in order to secure the most suitable one.   Bahana, Ltd is a company that specializes in the production of plastic components, molds, jigs, and equipment. During the production process of inspecting fixture items, pin components are required to assemble the components that need to be assembled.   At now, there are no explicit guidelines for choosing suppliers, and the selection process relies solely on subjective evaluations.   Consequently, it is necessary to establish supplier selection criteria through the utilization of the Analytical Hierarchy Process (AHP) methodology.   This strategy is highly suitable for resolving decision-making challenges.   Bahana, Ltd employs pairwise comparisons to evaluate four criteria: pricing, quality, communication, and location.   Bahana, Ltd has the highest criteria value of 0.36 in terms of quality, followed by a value of 0.33 in terms of pricing.   Hence, the paramount criteria in supplier selection are quality and pricing.   According to the AHP calculation results, PT A was determined to be the optimal choice as it obtained the highest weight value in comparison to other suppliers.

Abstract

This research was conducted to plan material needs and control the production capacity of bracket chambers at an automotive component company. The problems found were company excessively procures raw materials and unbalanced machine capacity in producing bracket chamber products. This research uses stages of the material requirements planning method, including calculating Rough Cut Capacity Planning (RCCP), Material Requirement Planning (MRP), and Capacity Requirement Planning (CRP). Implementing a MRP system enables organisations to accurately ascertain the specific kind, quantity, and timing of materials required for the production process. At the RCCP stage, capacity calculations are carried out on the CNC machine, press 1 and press 2 to find out whether the capacity of each machine can meet the company's MPS. MRP calculations are carried out to determine the optimal raw material ordering schedule using three lot sizing methods, namely Lot For Lot, Economic Order Quantity, and Period Order Quantity. At the CRP stage, each machine's capacity availability report will be made to meet bracket chamber production needs. The results of this research using RCCP and CRP analysis show that press 1 and press 2 have an unbalanced load between availability and actual demand, so it is recommended that these machines can also be used for other production so that the machines are not idle. Material requirements planning should use the Lot For Lot technique because it produces the minimum total inventory costs, namely IDR 12,710,751, with a material ordering frequency of 12 times in 1 year.

Abstract

This research discusses the analysis of work posture in the MMH activity of lifting products from thebending workstation to the Quality Control (QC) and packaging workstation. Observations weremade on the operator's working posture at the bending workstation in Kobar, Ltd, which producesrear brake components. The problems found were manual material handling activities in the form ofrepetitive lifting and placing products from the bending workstation to the QC and packagingworkstation. Work posture analysis was done using the Nordic body map questionnaire, REBA, andOWAS methods. Based on the results of the NBM questionnaire, fatigue occurred in the right elbow,left elbow, upper back, lower back, lower wrist, right wrist, and left wrist.Meanwhile, the results of the REBA method obtained a score between 4-7, which means that MMHactivities have a moderate risk and immediate improvement. Apart from that, based on the OWASmethod, a score of between 2-3 is obtained, so improvements must be made as soon as possible. Theimprovements made were by designing material handling tools using the principles of kaizenkarakuri and anthropometric ergonomics. This improvement eliminates the element of manualmaterial handling work and changes the position of the layout.

Abstract

Ensuring accurate measurement of precision components is critical in the automotive industry. This study investigates measurement challenges for screw shaft components at the Teaching Factory of Politeknik STMI Jakarta. The initial measurement system performed poorly, with 100% total variation attributed to measurement error and a Number of Distinct Categories (Ndc) of 1, indicating an inability to distinguish product variations. To address this, a Measurement System Analysis (MSA) using the Gage Repeatability and Reproducibility (GRR) method was conducted. Improvements, including operator training, regular calibration, and a custom jig fixture, were implemented. As a result, the GRR value decreased to 26.27%, with repeatability contributing 25.40% and reproducibility 6.74%. The Ndc value increased to 5, reflecting improved capability to differentiate product variations. These outcomes demonstrate that MSA is an effective strategy for evaluating and enhancing measurement systems. It is particularly valuable in vocational education settings to ensure measurement reliability, maintain quality standards, and support industry-relevant skill development.

Abstract

Inadequate or delayed supply of raw materials or components needed for production can lead to line stoppages. Reducing the frequency and duration of line stoppages is crucial for maintaining efficiency and meeting production targets. It can happen due to logistics problemsThis research was conducted in the logistics department of an automotive component company. One of the causes is the procurement of tooling, which needs to be improved for production needs. The tooling factor is part of the logistics scope and is the highest factor causing lost opportunities and line stoppages. To minimize the impact of line production stoppages, manufacturers often implement strategies like implementing a minimum stock of insert components. The problem-solving methodology includes a five whys analysis, conducting a Pareto diagram, determining the service level of the stock level, and calculating the maximum-minimum stock level. Based on the result, 17 types of inserts must apply stock levels to avoid stock shortages.
