Abstract

Footwear includes products such as shoes and sandals that have a function to protect the feet from injury due to extreme environmental conditions, such as rocky, wet, hot, or cold surfaces. PT Porto Indonesia Sejahtera is a company engaged in footwear, especially the production of sandals. One of the sandals produced is type 9009B-9. The problem raised in this final assignment is the downtime setting of the rotary machine, so the purpose of this final assignment is to provide a solution to the problem of downtime setting of rotary machine in upper PVC production. Data collection methods used to obtain primary data such as observation, interviews, documentation, and questionnaires while secondary data were obtained from literature studies. Solving the problem of downtime setting of rotary machine used the Plan Do Check Act (PDCA) method. The results showed that problems occurred are due to several main factors, such as human factors and methods. Human factors occur due to lack of understanding and no handover between shifts, while the method factor is due to no machine setting instructions, trials only on one machine and clogged materials. Hence, some solutions can be suggested to reduce the downtime setting of the rotary machine, namely by training, briefing at the beginning of each shift entry, making machine setting instructions, trials on all machines and making a grinding schedule. By applying these solutions, the downtime setting of the rotary machine type 9009B-9 machine was successfully minimized from 50 to 5 minutes.
