Abstract

Plant printing is a company unit tasked with fulfilling product packaging needs. In the production of printing plants from July to December, it was found that an average of 4% of products had defects (defects) exceeding the allowable tolerance limit of 2% per month, the biggest cause of problems with one of the machine components, namely the heater component. In these components found downtime of 3900 minutes for 3 months. Based on these problems, it is necessary to take preventive measures with a preventive maintenance approach by determining the schedule which is obtained from the calculation of the mean time to failure (MTTF) that the recommended maintenance interval is once every 5 days. Plus another improvement with the installation of an emergency lamp if the heater is indicated to be experiencing a mismatch. After the two approaches and improvements were carried out, a decrease in the number of product defects was obtained where the defect in the previous 6 months averaged 4% and in the following month after implementation the number of defects decreased to only 1.83%.

Abstract

Loading and unloading activities are the transfer of cargo from ship to port or vice versa. One of the loading and unloading activities is on liquid bulk cargo. Loading and unloading activities are related to ship services, namely ET indicators: BT. One of the indicators is Idle Time (IT). Idle Time (IT) is the number of unused working hours during loading and unloading work time at the mooring. IT value < RKAP indicates minimal obstacles to loading and unloading operations. The purpose of this study is to analyze Idle Time in liquid bulk loading and unloading activities every month and analyze the factors that can affect the performance of liquid bulk loading and unloading in 2021 at Company X. This research uses descriptive quantitative methods. The results of the analysis of Company X, namely Idle Time (IT) are not good because IT> RKAP. There are obstacles in loading and unloading activities due to various factors. The inhibiting factors are tool factors, environmental factors and worker factors. This requires good risk management.

Abstract

This research is discussed about the analysis of work posture in small-medium industries that produce sports shoes. UD XYZ Gresik is one of the companies in the athletic shoe industry that receives requests for shoes every day. Working hours for 9 hours with a break time of 1 hour. Production targets are sometimes not achieved, causing employees to work overtime. Along with the targets that must be achieved every day, employees in the shoe production room have to sit for a long time during working hours. Long working hours have an impact on musculoskeletal disorders, especially back pain. Working posture (sitting position) and length of work are factors that affect physical ability which continues to decline. Thus resulting in absenteeism and economic losses caused by a decrease in work capacity and a decrease in employee productivity. Novel Ergonomic Postural Assessment as an ergonomics method used as a tool to analyze the risk of ergonomics and working posture in the upper body to reduce the risk of musculoskeletal injuries in the production process. The results showed that the value of the first working posture was 6 (work posture needs further research and action is needed in the near future). For the second working posture, the final NERPA score was 7 (work posture needs to be checked further and action taken as soon as possible). Both of these scores require improvement due to the risk of severe musculoskeletal disorders.

Abstract

CV. Mahkota Kreasi Berlina is struggling to keep up with demand. Even though currently, CV Mahkota Kreasi Berlina has added working hours every week. In this case CV. Mahkota Kreasi Berlina has never carried out a workforce optimization calculation and made a comparison of additional workers with overtime hours. therefore, in order to meet demand, researchers will calculate the need for labor and make a comparison between adding labor and overtime according to production planning or with the workload analysis (WLA) method at the minimum cost. From the results of data processing, the minimum cost results are obtained, namely the calculation of the number of labor requirements in a 6 month period using 42 workers and overtime with a total cost of Rp. 495,800,000 per 6 months. Calculation of labor with WLA resulted in the company incurring substantial costs, where the results of the calculation of WLA amounted to Rp. 526,392,533 per 6 months

Abstract

Plastic seed products are products made from recycled plastic materials such as raw materials for plastic bags and some screen printing plastics. UD. ABC is a company that produces PP (Polypropylene) plastic pellets. The existing problems include the discovery of instability in the production of plastic pellets which is in a negative direction for the company, namely there are product defects in plastic pellet products that exceed the standard defect tolerance limit of the company by 2%. Based on the Pareto diagram, it can show that the type of protrusion defect is 69.56% more dominant than the type of connecting defect, which is 30.44%. Based on the control chart based on the p-chart, it shows that some dates are outside the limits of the control chart, namely the sample lot number 3 (March) of 0.0352, 4 (April) 0.0273, 7 (July) 0, 0134, 8 (August) 0.271. The data that comes out of the control chart limits exceeds the upper control limit (BKA/UCL) of 0.02649 and the lower control limit (BKB/LCL) of 0.02395. So what must be done to repair the engine factor is to carry out periodic briefings on how the machine works starting from setting the temperature and changing the filter. Meanwhile, the human factors section, namely directing the replacement of machine filter workers with temperature operators so that workers do not get tired easily, conducting periodic supervision of each worker for the leader and providing guidance on knowledge about machine work systems, mixing raw materials and operating machine temperature controls regularly.
