One method is used to improve the process
and provide to minimize solutions to improvement of the
company's internal standards that are flawed or
inappropriate and reduce the trend of increasing waste
products so that it increases for each period using the Six
Sigma method. Through the implementation of the
DMAIC cycle (Determine, Measure, Improve, Analyze
and Control) in Six Sigma, a problem can be clearly seen
at the root of the problem and can be fixed structured.
This research was carried out at PT. Tangerang RST, in
the Waste Water Treatment section by analyzing the cost
requirements for wastewater treatment for purposes,
where there were several ineffective and efficient costs so
that it could produce waste on the costs allocated for the
operation of Wastewater Treatment during the year 2015
From the results of the research that has been carried out
successfully found several root problems and several
solutions have been set to overcome the problem of
wasting operational costs of WWT. At the end of the
study it was also issued which succeeded in reducing the
operational costs of Wastewater Treatment by 360
million in the 6-month Phase of Time Control.
