Abstrak—Lean Six Sigma (LSS) is a widely accepted business improvement methodology in healthcare facilities, which aims to improve service, quality, reduce costs, medical errors and waiting time by implementing the principles of LEAN (lean) thinking with the Six Sigma methodology. The purpose of this study is to develop the lean sixsigma DMAIC method (Define, Measure, Analyze, Improve and Controlling) in medical device maintenance management, to reduce the high number of damage numbers in order to improve the quality of the achievement of Response to Repair Requests to conform to the standards specified in SPM 129 year 2008. The steps taken are 1. Define is to find the problem that occurs in this case is the low response rate to the repair of medical devices. 2. Measure is done by pulling data on requests for repair of medical devices and the results of the responses from January to June. 3. Analyze is done by measuring the value of the relationship between monthly damage and the response time to requests for medical equipment repair and then analyzing the causes. 4. Improve ment is done by way of brainstorming by determining what to do in accordance with the existing time line, then tested and if it is stable then implemented. 5. Controling is done by performing a Gemba Walk using a predetermined method to ensure that the project is running as expected. The result is that 5R steps (Compact, Neat, Clean, Diligent, Careful) can run in each treatment room and requests for repair can be reduced. The impact of this LeanSixsigma activity is the achievement of response rates for improvements from 75% to 80%. And the most important thing is the 5R principle can run well.
