Abstract

The process barcode symbologies (Marking CODE). Valve core parts (Shaft). Butterfly (Butterfly Valve) Model Z011-A DN100 the sample. Current needs of customers, 60,000 pieces per month. But the capacity to

produce up to 20,000 pieces per month. For companies, it is necessary to open up an additional four hours of overtime. This Research aims to increase production to the production line. By trying to reduce the cycle time

for stroke outweigh the needs of the client, which is the main reason for the company to extend the time of performance. Tools used in the operation of this feature. The seven wastes, reduce seven quality control tools

used for data collection. In order to analyze the problem. And define solutions. Then, to improve performance, reduce cycle time, make the value equal to or less than the timing requirements of the clients. Design

techniques jig. Results showed that the cycle time can not be beat for customer needs. To 11.44 seconds per

piece, representing 68.68% reduction in hours of work for 4 hours per day, representing a 33.33% reduction in the number of employees not one person representing a 50% productivity increase of 97.68%.
