Abstract

Vehicle queues formed in front of the gate of the ticket collection counter at STS Mall can cause problems and queue lengths that can interfere with other traffic movement systems. Therefore, it is very important to review the queuing system at the gate of the parking ticket collection counter at STS Mall. This study aims to examine the queuing system and determine alternatives to improve four-wheeled vehicle queuing services at the ticket collection counter to enter the parking lot at STS Mall. The main data needed in this study are vehicle arrival rates and counter service times. The data were obtained respectively using traffic enumeration methods and sampling observations, which were carried out at the entrance counter of four-wheeled vehicles and carried out on Saturdays and Sundays. The analysis method uses Queue Theory. The results of the analysis show that the number of counters 1 piece is still able to serve the current level of vehicle arrivals which gives a value of n ranging from 0.34 - 0.37 vehicles (( 1 vehicle) , q ranging from 0.08 - 0.06 vehicles (( 1 vehicle), d ranging from 8.2 - 8.6 seconds, and w ranging from 2.1 - 2.5 seconds. At an arrival rate above 600 vehicles / hour are no longer able to be served with the number of counters (N) as much as 1 piece without improving the queuing system

Abstract

This research aims to identify and overcome bottlenecks in production process at PT. XYZ Indonesia, especially in HA Export Department on SMC Big Volume Lane. Bottlenecks were detected in Visual Acc and Housing processes, which resulted in decreased efficiency and productivity. The method used in this study is line balancing with the Pro Model simulation approach, which allows analysis of improvement scenarios without disrupting ongoing operations. Data collected includes process time and machine capacity. Initial simulation results showed significant idle time 15,4%, with accumulation at Raw Material workstation (12.30%), Housing workstation (1.20%), and Visual Acc (1.90%). After the improvements were made, including increasing the Raw Material capacity to 20 pcs, the Housing process to 3 pcs, and Visual Acc to 3 pcs, the bottleneck was successfully eliminated from 15.4% became 0% and the production flow became more stable. This research provides practical solutions to improve efficiency and reduce cycle time, and can be a reference for companies in implementing line balancing and simulation methods to improve productivity in the manufacturing industry.

Abstract

Garment industry is a labor-intensive manufacturing sector with a complex production flow, highly susceptible to bottlenecks. Unresolved bottlenecks can lead to decreased efficiency, increased waiting times, and reduced productivity. This research aims to analyze bottlenecks in the garment production process using a simulation approach with ProModel software. The research method was carried out using a quantitative-descriptive approach, starting with production system selection, process flow mapping, and simulation model development and testing. The results of the original model simulation show a production output of 1.719 units, with a bottleneck of 3,86% and a cost of USD 38,01. This situation requires improvement, which was achieved through scenario 1, where production capacity at each location was increased, considering a relatively similar cost of USD 41,40. This change reduced the bottleneck to 0,60%, and total production increased to 1.811 units. In scenario 2, with a similar cost, the author recommended further adjustments to the production capacities at the required processes. After conducting the simulation, total production increased to 1.908 units, with a cost of USD 41,42. The simulation using ProModel proved effective in systematically identifying and evaluating bottleneck solutions. This research provides practical recommendations for garment industry management in making data-driven decisions to improve production efficiency. keyword: Bottleneck; Garment Industry; Simulation; ProModel; Production Efficien

Abstract

PD.ABC experienced problems with an inefficient production system. This is indicated by the minimum amount of output that can be sent. This becomes a source of problems when there is a large order of dorokdok skin crackers, which cannot be completely filled. Therefore, this research will analyze the factors that become obstacles in the dorokdok skin cracker production system using a system modeling and simulation approach. The conclusion was that in the PD dorokdok skin cracker production system. ABC still lacks workers for the production process. This causes the failure rate in sending dorokdok skin crackers to still exist and losses occur. With 2 operators, the maximum output produced is only 63 pcs/day with costs incurred of Rp. 2,950,000 and the profit obtained is only Rp. 1,260,000 or it could be interpreted that PD.ABC suffered a loss of Rp. 1,690,000. After improvements were made, by adding 3 operators it was seen that the simulation results did not show any failures in the production process flow of dorokdok skin crackers with the maximum output produced being 500 pcs/day, the total costs incurred amounting to IDR 6,850,000 and the profit obtained amounting to IDR 10,000,000 or it could be interpreted as PD.ABC experiencing a profit of IDR 3,150,000. So it can be concluded that the improvements made have been effective by increasing human power thereby increasing PD dorokdok skin cracker production capacity. A B C

Abstract

This study focuses on initiatives to enhance production quantity at PT ABC. The study applied a simulation-based approach using ProModel software to test various improvement scenarios without interfering with actual production activities. The data collected includes processing time at each workstation and machine capacity, which were used to build an accurate simulation model. The simulation results showed a significant increase in productivity from 35 to 78 units per hour after implementing the second improvement alternative involving additional manpower. This study offers practical and data-driven solutions to enhance production efficiency, reduce cycle time, and eliminate bottlenecks. The findings serve as a valuable reference for companies aiming to implement production line optimization strategies and simulation modeling to support continuous improvement in manufacturing performance.
