Abstract

This study aims to identify, analyze, and provide solutions to bottlenecks in the plastic cup production process at PT 'X'. The bottleneck caused by static electricity lamps led to a decrease in production efficiency, with a downtime of up to 20 minutes per day and a reduction in capacity by 450,000 cups per month. The Capacity Requirement Planning (CRP) method and cycle time analysis were employed to evaluate machine capacity and identify the root causes of production constraints. After improvements, including the addition of static electricity eliminators, the cycle time was optimized from 0.108 seconds/cup to 0.0864 seconds/cup, downtime significantly reduced to 2 minutes per day, and defective products decreased by up to 80%. Production capacity increased from 2.4 million to 3 million cups per day, meeting the target. This study highlights that eliminating bottlenecks through technological optimization can significantly enhance production efficiency and the company's competitiveness.

Abstract

The job of a porter is often synonymous with unergonomic working conditions and high risks to health. This is caused by a mismatch in the working posture of porters. Therefore, this research aims to design an ergonomic goods trolley for porters based on anthropometric analysis. This research uses a participatorydesign method that involves porters in the design process. The porters' anthropometric data is measured and analyzed to determine optimal trolley dimensions. Based on the data that has been taken, the researchresults show that the ergonomically designed goods trolley has dimensions that suit the dimensions and body posture of porters. So it can reduce the workload and increase the comfort of porters, such as wheels that rotate easily and sufficient storage space. In conclusion, designing ergonomic goods trolleys for porters can improve the health and safety of porters. This trolley can be a solution to overcome the health problems that porters often experience due to work.
