Reduction Bottle Cost of Milkuat LAB 70 ml Using Optimal Parameter Setting with Taguchi Method

The profit margins decrease up to 30%; the bottles are as the main cause of 10%. This study focuses on bottle analysis and aims to get the optimal weight of the Milkuat LAB 70 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 S2 and S4, for setting the optimal level is S2 (A3) is 1.25 mm and bottle S4 (B3) is 0.95 mm, the optimal bottle weight is 7.00 gr from before 7.80 gr, with current bottle strength 19.64 Kg with the previous weight is 19.80 Kg, the value of QLF (Quality Loss Function) is IDR. 7,000, - from before is IDR. 7,815, - deviation of IDR. 16.02, - and efficient per Day IDR. 28,836,000, - with output 1,800,000 bottles per day and the results of transportation tests remain on 22 cartons stack; the reject decline production ratio is not too much different for 1 hour production, 1 production shift and up to 1-3 months of production using a bottle of 7.00 gr with the conclusion of the statistics that is "Not Significant Difference from 7.80 gr" that means that the results are good in productivity and cost efficiency.
