Reduction bottle cost of Milkuat LAB ۷۰ ml using optimal parameter setting with Taguchi method

The profit margins decrease up to ۳۰%; the bottles are as the main cause of ۱۰%. This study focuses on bottle analysis and aims to get the optimal weight of the Milkuat LAB ۷۰ ml bottle by not forgetting about some standard parameters that cannot be changed. This experiment uses the Taguchi method, which includes knowing the factor level settings, optimal settings, optimal bottle weight, optimal bottle strength, getting QLF (Quality Loss Function), results from transportation test, and reject ratio in the production line. And some additional methods such as transportation tests have also carried out in this study. The results of this study are that the influential level factor settings are S۲ and S۴, for setting the optimal level is S۲ (A۳) is ۱.۲۵ mm and bottle S۴ (B۳) is ۰.۹۵ mm, the optimal bottle weight is ۷.۰۰ gr from before ۷.۸۰ gr, with current bottle strength ۱۹.۶۴ Kg with the previous weight is ۱۹.۸۰ Kg, the value of QLF (Quality Loss Function) is IDR. ۷,۰۰۰, - from before is IDR. ۷,۸۱۵, - deviation of IDR. ۱۶.۰۲, - and efficient per Day IDR. ۲۸,۸۳۶,۰۰۰, - with output ۱,۸۰۰,۰۰۰ bottles per day and the results of transportation tests remain on ۲۲ cartons stack; the reject decline production ratio is not too much different for ۱ hour production, ۱ production shift and up to ۱-۳ months of production using a bottle of ۷.۰۰ gr with the conclusion of the statistics that is "Not Significant Difference from ۷.۸۰ gr" that means that the results are good in productivity and cost efficiency.
