ANALISIS PERFORMANCE BAND SERVICE MESIN ATB-I3 DENGAN PERHITUNGAN AVAILABILITY

Section A2 is a team from the Engineering Department assigned to

Section building and Section Venting Plant A. In Section A2, band

service problems are problems that have the highest downtime and ATB

I3 machines are machines that have the highest downtime due to band

service problems. The high downtime band service is caused by a

problem with the lock band service system, namely the motion locking

system on the band service component. Therefore, a modification was

made by changing the design of the lock band service. Modifications

made require components such as ACM B50 S60 pneumatic cylinders,

10 mm plates, linear guideways, and proximity sensors. The pneumatic

cylinder is used as a locking system tool that will push the lock plate, a

10 mm iron plate is used as a component holder and a lock band service

modification tool, a linear guideway is used as a support for pneumatic

cylinder motion in locking, and a proximity sensor is used as a lock

motion detection device. band service and will send a signal to the PLC

for the next process in the service band. After the modification is

complete, downtime is calculated as well as MTTR and MTTF

calculations to determine the availability value. Based on the

calculations made by the author, after the modification there was a

decrease in downtime of 52.97% and an increase in availability of

1.64% compared to before the modification.
