Implementasi Value Stream Mapping Untuk Identifikasi Pemborosan Unit Pengantongan Semen ( Studi Kasus di PT. Semen Padang )
The packing factory of PT Semen Padang produced the cement bags consisting of two types are pasted. In assembilng the pasted type especially with the 50 kg DW 3 red ply strip some problems often occur so that the production ratte is not reached. In the experiment, some wastes are identified. The wastes like waiting time and product defect take place in the mapping of value flow because of the high level of wastes on production floor. The mapping stage is done to map all activities with added-value and without added-value in stocking chain of the company relating to waiting time and product defect, so that the activities without added-value can be eliminated. In the mapping stage the method of VALSAT (Value Stream Mapping Tools) is used are Process Activity Mapping, Supply Chain Response Matrix, and Quality Filter Mapping. To prevent the re-emergence of wastes, it is proposed an application of poka yoke on the production floor.
