Abstract

This analysis focuses on the use of the Six-Sigma and Kaizen methods to find out the work processes by PT PERKASA PRIMARINDO that caused defects in their tile products and then formulate actions to reduce the number of defects and is thus expected to increase the quantity of quality products. The analysis results in  a DPMO value of 464.1488, or equivalent to a Sigma level of 4.81. As the perfect DPMO value is 3.4 (equivalent to Sigma 6 level), this shows that PT Perkasa Primarindo still has the opportunity to improve the quality of iheir tile products. The p-chart shows the proportion of defects that are unstable and outside the upper control limit (UCL) and lower control limit (LCL) during production in 2020. Furthermore, from the analysis it is also known that there were two main causes of defects, namely the over-temperature of HD dryer, and a poor cleanliness. With these findings, an action procedure has been proposed through the Kaizen method which is expected to control the quality of tile products so that they are still within the threshold value.

Abstract

an Research analysis was carried out on designing work tools to avoid musculoskeletal disorders using the Rapid Whole Body Assessment (REBA) method at CV Rama Teknik. Data was collected through asking questions during interviews, and filling out the Nordic Body Map (NBM) questionnaire to ascertain which parts of the body experienced discomfort which could cause a certain level of musculoskeletal disorders. The posture conditions of assembly process workers that can cause musculoskeletal disorders are sitting work posture and standing work posture. The results of the Pick Test observations showed that the frequency of the slouched sitting position was 41 times with a percentage of 46% and the frequency of the upright sitting position was 49 times with a percentage of 54%. The results of the Nordic Body Map questionnaire indicate that the risk level for workers' MSDs is "medium" with an individual score level of 62 for worker 1, 62 for worker 2, and 58 for worker 3. In accordance with the risk level classification based on the total individual score with a score level of 50-70, it is at “medium” risk level. The REBA calculation result for the standing work posture for the first worker is 3, the second worker is 2, and the third worker is 2, so the risk level for the standing work posture for all assemblers is "low", while the REBA calculation result for the sitting work posture for the first worker is 5 , the second assembler is 6, and the third worker is 6, then the risk level for sitting work posture is "medium", according to the REBA risk level if the score is 4-7 then the risk level is "medium".
