| PT Indogravure is a company engaged in the printing of flexible packaging products. The Company has three work stations starting from printing, laminating, slitting. The problems that arise when this company has many products produced have a defects. Defects generated for each work stations about the same. Disability minimum set by the company is 11%. However, the company's production in excess of the limit minimum defects that have been set by the company. From the observation, it was found that the laminating process that often produces output defect and suffered engine problems is quite high. To overcome these problems, the company wants to determine the cause of waste in their company. Therefore, it can be done with or six sigma DMAIC method. In the define phase, the company would like to know the process from upstream to downstream by using current state value stream mapping. From the map, a score of 68.98% OEE. it is still far from the overall OEE is equal to 85.4%. In addition, the company must describe anyone who plays a role in the production process up to the hands of consumers by using SIPOC. Companies also need to know the current sigma level so that with the sigma level the company can improve its quality by using DPMO. From the results of DPMO known that the company is at 3 sigma level and must be repaired. In the measure phase, calculation by map control and process capability. From the calculation it is known that the company has not had a good process capability and the company who did not produce products according to specifications. In the analyze method, the calculation Pareto diagrams are then analyzed with the fishbone diagram and to more clearly aided by the FMEA. From the results of Pareto diagram, obtained the highest defect 5 will be analyzed further. In the improve phase, there are two proposals that give the 5S and engine maintenance system. In 5S, conducted the implementation by sort, set in order, shine, standardize and sustain. Furthermore, the calculation engine maintenance, it was found that the company had time interval replacement for 1200 hours with interval wkatu examination of 312.9231 hours. So from these calculations, generate future state with total PCE at 11.15% and OEE 96.27%. |
