TAGUCI LOSE FUNCTION PADA UJI BEDA PROSES HARDBAIT PERBAIKAN SPRAY PAINTING

The more detailed the manufacturing process, consistent operations will be with hope of producingbetter products according to their characteristics. problems found by researchers were high rejects inthe form uneven colors, poor color resistance harbait, unbalanced working baits and imperfect dimensionsand shapes harbait. This study uses Taguchi method showing which parts do not work optimally bypaying attention quality that deviates from target value so it can reduce costs resources aminimum. methodologywas carried out basedon experimental plan, in addition tousing different paired sample t-test determine difference before after improvement. samplingtechniqueused was purposingsampling technique. Data weretakenwithcertaincriteria, specifically for hardbaidproducts, a certain period 35time at 07:00 WIB on first shift spray painting department worker.Analysis calculating loss qualitywithout having update function itscharacteristics. product is using Loss calculation. Cases afterrepairs earned Rp. 11,927,00/pcs. So thedifference between average increase beforeand Rp 5,389/Psc.In t test, there are differences repair. Furthermore, relationship test becarried looking results correlation output resulting no aftertherepair.Meanwhile,identificationofcausesandeffectsofdecreasedproductivityusingFishbonediagrams.
