PENERAPAN PETA KENDALI X DAN R PADA PROSES FILLING SUSU PASTEURISASI DI KUD “DAU” MALANG
ABSTRACT: The purposes of this
research were to develop an - R control
chart of the filling process in a particular pasteurized milk industry in order
to improve the performance of the process. Based on the data of the milk volume
filled in the container, the - R control
chart of the filling process was developed. It was found that an average volume
( ) was 143.88 ml; and the respective values of UCL and LCL were 147.74 ml and 140.52ml, with an average
volume range (R) of 5.83 ml; UCLR = 12.30 ml; and LCLR = 0. The chart showed
that the center line and limits of the X control exceeded the predetermined
value of 140 ± 5 ml, with the average volume of 143.88 ml, which was above the
set value of volume 140 ml. The value of
Cp was 0.66 (less than 1,00) and the Kane performance index, CPK = 0,15 which
was equal to the CPU. It means that the operation of the filling process was
under its capacity. Since the filling machine used was a semi automatic one, to
reduce the excessive filling may be carried out either by upgrading operator or
machinery performances.
Key word: control chart, filling process, pasteurized
