The research studies the factors that influence trimming skills in pineapple production, to increase productivity in operations. The results indicated that there was a problem with relatively low pineapple trimming skills among employees, as evidenced by the average productivity of 3-4 pieces per minute and a waste rate of 2.5%. The study was conducted over 5 months and involved a sample of 41 individuals. The research employed a combination of feedforward and feedback techniques along with peer-assisted learning. It revealed that certain demographic factors have an impact on productivity. Male employees exhibited higher productivity, with an average of 10.33 pieces trimmed per minute compared to female employees. Part-time employees also demonstrated greater productivity, averaging 9.29 pieces per minute compared to permanent employees. Regarding age, the range of 21-30 years was found to be most suitable for work, with an average productivity of 8.28 pieces per minute. Additionally, employees with work experience ranging from 1 to 5 years were the most effective, achieving average productivity of 8.27 pieces per minute. Furthermore, the training program utilizing the combination of pre-practice information provision and feedback techniques, along with peer-assisted learning, resulted in a significant improvement in pineapple trimming skills. The training led to a 39% increase in skill levels compared to the pre-training data collection. Moreover, the resulted in a 60% reduction in defects caused by the pineapple processing process. Overall, these findings provided valuable insights into the factors influencing pineapple trimming productivity and highlight the effectiveness of the training approach employed.
