The results of the study indicate a medium level of risk with a CV value of 9%. In addition, the results of HoR phase 1 obtained 22 risk events and 25 risk sources. Fourteen risk sources were identified as priority risks that require the design of a risk management strategy. The results in HoR 2 show 10 management strategies that can be implemented by the company in handling priority risk sources. The risk management strategies are based on the highest to lowest ETD values in sequence, namely cross-checking mechanisms, production rescheduling, team coordination, incoming raw material control, technical skills training, replacement of damaged machine parts, safety stock planning, preventive maintenance, temperature monitoring, and the use of magnetic separators.]]>
