Usulan Peningkatan Efisiensi Keseimbangan Lini Dengan Value Stream Mapping Dan Yamazumi Chart Pada PT.PAI

Abstract

PT. PAI is a footware company that produces sports shoes. The production
process at PT. PAI, has a waste of 15.891%. To overcome the problems that
occur, this study was conducted with the aim of identifying and proposing waste
elimination. The method used is a lean manufacturing approach. One of the tools
used is Value Stream Mapping (VSM) and Yamazumi Chart. The first stage to
solve the problem is the identification of waste using the Waste Relationship
Matrix (WRM), Waste Assessment Questionnaire (WAQ) and VALSAT. The
second stage is carried out by designing the current Value Stream Mapping
(VSM), designing the proposed improvements using the Yamazumi Chart to
balance the production line and designing the Future VSM based on the results
of the proposals that have been given. The result of identification using these
tools is known that the biggest waste is waste in the process with a percentage
of 15.891% followed by overproduction of 15.774%. Based on the calculation
using VSM and Yamazumi Chart, elimination of waste can be done as much as
5.48%, reducing the number of workers by 32 people and reducing the number
of work stations by 16 work stations
