Flood pump performance improvement analysis using DMAIC method.

In the past, many areas that were once water suction areas have become residential areas, shopping malls, offices and other commercial centers. When it rains, all the water flows directly into the river, and a little bit is absorbed by the soil because it has been covered by the cement casting. This increases the water flow in the rivers of Jakarta. The focus of this research is to improve the performance of flood pumps. Observing the drainage of (A) River and (S) River, we compare it with the pump performance of the (A) River gate. By using the statistical software tools included in the Minitab program, it helps to obtain faster and more accurate results. Normality test, Gage R&R, capability analysis, Anova and other variance test, and two-sample T test are a series of tests performed in this study. In the improvement part, design of experiments (DOE) will be carried out. The pump in this study is the second sample of the three pumps provided by (A) Pump House. The Sigma level before repair was 2.27σ, and after repair it was 5.91σ. This has had a major impact on improving the expected performance of the flood pump, enabling it to cope with the increase in water flow in the coming years. [ABSTRACT FROM AUTHOR]
