The Analysis of Waste in Paving Production Process by Using Lean Six Sigma Method

— CV. X works in manufacturing such as produce paving, concrete brick, road curb, concrete buis, culvert, udith, and panel that located in Cilegon, Banten. The commonly problem faced by CV.X is found some waste in process of paving production such as waiting and transportation. Production pprocess of paving are stirring, printing, drying, and watering process. The aim of this study is to know the score of Process Cycle Efficient (PCE), the level of sigma paving hexagon. In this research, the researchers used Lean Six Sigma and FMEA method. According to analysis of data, known that the initial Process Cycle Efficiency (PCE) is obtained at 8,94%, the sigma level of paving hexagon is 4.02, and waste found waiting, transportation, invention, and defect. The improvement conducted for better condition of Lean, it is increasing the score of Process Cycle Efficiency (PCE) by changing value stream and decreasing or deleting the waste activities. The result of improvement got the Process Cycle Efficiency (PCE) score is increasing becomes 96.94%. from analysis of FMEA, type of waste defect with type broken paving become repairing priority firstly because have high value of RPN that was 270 and repairing priority continuously to reduce waste of transportation, defect by type of cracked paving, and waiting .
