SIMULASI PENSTABILAN KADAR TAWAS PADA PENGOLAHAN AIR PDAM KOTA SEMARANG DENGAN METODE EULER
Abstract: To the purpose
research is determine solution to optimize water processing with controls chart
as tool of observation and Euler method to substance dissolution on that case
so acquired maximum gain. Observational method that is utilized is case study.
Data that is taken is pH and muddiness of water. Hereafter been done analisis
data by use of chart controls statistika to conduct quality and euler method on
that case so acquired maximum water processing. From analisis extrapolation
that did by controls chart to utilize program Visual Basic on pH's data is
gotten xbar = 228,49, Rbar= 10,6, LKA = 7,94,xdoublebar = 7,62 and LKB = 7,29.
On pH's graph has no dot out of the sphere LKA and LKB, therefore said by means
controlled process its pH's quality uninfluenced by a cause. Meanwhile on
muddiness data is gotten xbar = 6820,56,Rbar = 23048, LKA = 513,572 and =
227,35 and LKB = 0. On muddiness graph exists dots out of the sphere LKA and LKB
as dot 1, 9, 15, and 17, therefore said by process is not controlled by its
mean muddiness quality regarded by a cause. Taking conclusion from chart's
purpose controls this with action issues quality cause that took in by outboard
dot controls its mean take a decision production will be discontinued at the
moment that condition.
