Abstract

PT. XYZ is a manufacturing company that produces Silent Chain and Rim, during the period September 2022 – February 2023 according to data from the Production Department the level of NG goods in the period increased compared to the previous period. Many factors affect the level of NG goods, one of which is the Performance of PT. XYZ. This study aims to determine the influence of leadership style, relationships between employees, and working conditions on the performance of PT. XYZ. The sampling method used was simple random sampling and determining the number of samples in this study using the slovin formula resulted in 161 respondents, the data used were primary data with questionnaire techniques, hypothesis testing was carried out with multiple linear regression analysis techniques using two-tailed tests with the Analysis of moment structure version 24 application . The results showed that there was no influence between the variables of Relationship Between Employees on Employee Performance with a value of P>0.05 while Leadership Style and Working Conditions had an effect on Employee Performance with a value of P<0.05

Abstract

PT.IJK. has implemented Total Productive Maintenance to improve the efficiency and effectiveness of the manufacturing company as a whole. However, the implementation is still not optimal as seen from the high incidence of machine damage and the value of machine downtime. This study aims to measure the value of equipment effectiveness, find the root cause of the problem and provide suggestions for improvement. The research was conducted on the drayer machine which has the highest breakdown rate. The study began by measuring the achievement of overall equipment effectiveness (OEE) value, then identifying the six big losses that occur. The results showed that the average OEE value on the drayer machine was 76.36%, this effectiveness value is classified as very low because the standard OEE value for world-class companies is ideally 85%. The biggest factor affecting the low OEE value is the performance rate with a percentage factor of six big losses on Reduced speed loss of 18.17% of the entire time loss. The proposed corrective action is to prepare autonomous maintenance equipment, provide training for operators and maintenance technicians and supervise operators regarding workplace cleanliness.

Abstract

This research was conducted at PT. XYZ is engaged in the textile industry. The problem was experienced due to defects in the Rayon Fiber production process. The purpose of the study was to determine the Rayon Fiber production process at PT. XYZ, to determine the factors causing defects using the Fault Tree Analysis (FTA) and Failure Mode and Effect Analysis (FMEA) methods, and to provide suggestions for improvement to reduce product defects. The results of the observation showed that there were three types of defects, including White Brightness, Yellow Brightness, and Damaged Wrapping. Of the three aspects, the most dominant types of defects were White Brightness, and Damaged Wrapping seen in the production process in December with a percentage of defects of 14.8%. From the Pareto diagram, it is clear that three problems cause defective goods. To reduce the number of faulty goods, the most common issues - namely, damaged wrapping and white brightness defects - must be addressed by fixing the most defective goods using the 80%/20% approach. After obtaining the severity, occurrence, and detection values related to window product defects, the RPN value will be calculated by multiplying the values above (RPN = S x O x D). By doing the repairs, it resulted in improvements marked by a decrease in the RPN value from 1290 to 553 or 42.8%. The root cause of the problem was because the operator did not follow the existing work standards and did not use the navigation system during the production process. From the results of the study, several suggestions for improvement were obtained, namely conducting periodic supervision and providing re-training to operators regarding the importance of working according to SOP.
