PT Furnindo Inovasi Teknologi is a company operating in the furniture industry,
which produces several types of sofas. Some of the problems that occur in the
company include the production process, which is currently unable to fulfill orders
on time, production lateness, a lack of workers, and improper placement of tools
and materials. However, the main focus of the research is on the problem of
production lateness with the root cause of the bottleneck which causes the
production line to be less efficient. Therefore, this research aims to reduce
production lateness.
The research uses cycle time data, then calculated the standard time using the
working time measurement. Next, the current line efficiency value was calculated
and the RPW (Ranked Positional Weight) and CPM (Critical Path Method) methods
were used as the alternative solutions for improvement. Then, based on this
method, line efficiency calculation and analysis of existing alternative solutions are
carried out.
The research results stated that there was an increase in line efficiency of 12.96%
from the initial efficiency of 63.22% to 76.18%. Apart from that, this research also
succeeded in reducing production lateness by 71.02%, from 20 days to 5.80 days.
