Based on PU/PR Regulation No. 09/2008, this figure is included in the category of moderate compliance (60-85%) while the type of PPE with a very good use rate (≥85%) is a helmet (95%), glasses (86%), boots (95%), and work clothes (100%) while the type of PPE with a fairly good use rate (60-85%) is glove (41%), Safety Belt (51%), Ear Protector (51%), and Full Body Harness (34%). The results show that the use of PPE such as helmets (95%), safety shoes (95%), and work clothes (100%) have met the standard, while Full Body Harness (34%) and masks (41%) are still low. Conclusion This study emphasizes the importance of increasing OHS training and strict supervision of the use of PPE, especially for equipment with low compliance levels]]>
