ANALISIS PERFORMA TIMBANGAN MESIN PENGEMASAN KOMODITAS PRODUK MAKANAN

Abstract

Production processes must be controlled in manufacturing indutry due to  conformance to specifications. The study was carried out at a packing machine consisting of two weighing equipments (S1 and S2) in a food industry in Jakarta using Statistical Process Control. Control chart is made to describe the running process against  specification limits, then the performance of the scales is measured by calculating the process capability index.  Based on the measurement of  process capability of the packing machine, Cp value of S1 scale is 0.63 and the Cpk value of S1 scale is 0.57. As for the Cp value of S2 scales is 0.82 and Cpk value of S2 scale is 0.72. Cause & effect analysis using Ishikawa diagram show that variations occurred due to the presence of product deposits attached to the feeder screw and bucket scales. Therefore  it needs to make regular cleaning maintenance and replacement of discharge door.
