Propose Improvement Maintenance Activities of Screw Press to Reduce Waste Using Lean Maintenance Concept

Abstract

Maintenance is an important factor to achieve the goal of becoming the best manufacturing company. To achieve the company that has the best performance, the treatment strategy should be linked to strategies such as the concept of lean manufacturing. Lean maintenance is a process to achieve continuous improvement. This system focuses on adding value and reducing waste in the care process so that maintenance lead time can be reduced, as well as identifying the waste that occurs in the activity of a treatment using Value Stream Maintenance mapping (VSMM), identify the factors that cause waste most dominant use of Root Cause Analysis (RCA), identifies the critical part of the screw press machine using Reliability Centered Spares (RCS) and provide recommendations for improvements screw press machine maintenance activity. Problems often occur is the waste to the type of waiting where the facts occurred in the field is a process of waiting for components, equipment and transport documentation wait staff, thereby extending the time to repair any damage. This study aims to reduce waste waiting in the screw press machine maintenance activity. The most high maintenance time is the first press of 10 132 minutes. The dominant type of waste is waste waiting that contribute to waste by 35%. a critical component of body cage, cage feed, feed worms, and main shafts. Improvement maintenance systems that do reduce the lead time on the first maintenance ress be 5,100 minutes.
