This study aimed to analyze the correlation of LOTO system that has been implemented in MANDO, involving the LOTO training, supervision, and reward and punishment with the LOTO implementation behavior of the Maintenance Engineer. This research was observational with cross sectional study. Samples were 50 respondents taken by simple random sampling with a population of 97 Maintenance engineers. Data were analyzed statistically using Chi Square test (α <0.05) and continued by observed value of phi coefficient. The results showed that most of the Maintenance engineers in the Maintenance Engineers & Production Department. Mando Automotive India Pvt Ltd had implemented LOTO in every maintaining and servicing equipment well. Statistical analysis showed the variables have a significant correlation with LOTO application on Maintenance engineers was supervision (sig = 0.047; phi value = 0.312). LOTO training, reward, and punishment did not have significant correlation with LOTO application. In conclusion, supervision had significant correlation with LOTO implementation on Maintenance engineers. Mando Automotive India Pvt Ltd should increase transfer knowledge to Maintenance engineers by putting LOTO signs around shop floor, increasing supervising role of the maintenance engineers and OSHE Department, making a LOTO training and refresh training schedule and evaluating it, and also giving rewards to Maintenance engineers regularly.
