Abstract

PT XYZ is a company engaged in steel fabrication, and there are several issues related to the production system of the PT Metso project that are known to be the source of bottlenecks at certain workstations, causing material flow on the production line to be impeded.  This research will discuss the calculation of standard time and identify bottlenecks at several workstations. The application of the theory of constraints that can help identify and control the sources of constraints with several objectives such as maximizing throughput and creating detailed calculations of time buffers and Drum Buffer Rope maps to address issues. Then an analysis was conducted using a fishbone diagram and the Five-M Analysis method to determine the causes that occurred. Based on the calculations that have been made for the company's capacity and capability, a rescheduling of the Spray Bar production process has been carried out with an additional working time of 19 hours divided into 2.5 hours per working day. It is known that the bottleneck workstation is located at the Fit-up/Setting workstation with a percentage of 133%. To reduce this bottleneck, the company provides buffer time or time that serves as a cushion with the aim of protecting the production rate (throughput) Before the bottleneck workstation, it took 19.5 hours, and after the bottleneck workstation, it took 2.2 hours.

Abstract

This research aim to solve the problem of ergonomic standart in the process of making an upper shoes by implementing Rapid Entire Body Assessment (REBA). This method is suitable to solve job body posture problem of the worker of PT XYZ based in Sidoarjo. PT XYZ is an international company and one of the expantion company from Denmark, they produce high quality shoes with more than 7000 workers. There are several plaint from the worker that they had a featigue in some part of te body. REBA assess the score from the top of the body to the bottom of the body and giving report are report of the posture risk. By using this method, the solution can be found with giving the right posture of the worker body while working their duty. The result of the research are confirmed to reduce the risk of musculoskeletal disorders (MSDs) the posture need an improvement by changing the moves of trunk, upper arm, and wrist. Reba score are known in 6 and it’s increasing to 3 after the improvement.

Abstract

This study analyzed the initial symptoms of fatigue and measured the level of fatigue with the subjective self rating test method as the subjective method, the CVL (Cardiovascular Load) method as the objective, and the independent sample t test at the Plaza Surabaya sports station. shop. Shift work in the workshop has the potential to pose health risks in the form of fatigue due to differences in physical workload experienced in each shift. Sports Station Plaza Surabaya outlets face work activity problems that are at risk of ergonomics, with several worker complaints due to work shifts that only do rotating shifts per month and unclear employee jobdesk placements. The Subjective Self Rating Test method is used to identify early symptoms of employee fatigue by filling out a questionnaire, the CVL method is used to measure pulse to obtain the level of physical workload fatigue experienced by employees. While the independent sample t test test is to find out whether there is a significant difference in the level of shift fatigue at the Sports Station Plaza Surabaya store. get the highest classification value in shift 1, for the independent t test test method get a significance value of 0.01 which means there is a significant difference in the level of worker fatigue in shift 1 and shift 2.

Abstract

PT XYZ is an airport manager in Indonesia engaged in the business of development, trade and services, and genuine estate. In the manual transportation of goods, extreme positions are still carried out. So that complaints of pain appear in several parts of the body, such as the neck, back, upper arms, and legs. The purpose of this study was to determine musculoskeletal complaints and analyze the work posture of workers. Risk assessment using the Rapid Entire Body Assessment (REBA) method because it can provide a more detailed evaluation of the level of risk of work posture as a whole. Based on the results of risk assessment research using the REBA method, workers in the Loading-Unloading Apron Area squatting position get a work posture risk value of 9, and the Apron Area standing position gets a work posture risk value of 8, where the value includes action level 4. For workers in the Loading-Unloading Makeup Area, the bending position gets a work posture risk value of 11, where the value consists of action level 4. Suggestions for improvement that can be proposed are making changes to the position of work postures and designing assistive devices.
