This research aims to produce compatibility between the policies of Abon Surya with the Economic Order Quantity raw material control method, namely the purchase quantity of the Abon Surya policy has an average purchase of 770 kg, for the frequency of purchasing raw materials for jack beans 5 times, for security and point supplies. There is no reordering policy with a total inventory cost of IDR 251,640. Meanwhile, the EOQ method has an average purchase of 1,313 kg. the purchase frequency is only 3 purchases, the security inventory is 90 Kg and the number of reorders is 204 Kg with a total cost of inventory required of IDR 173,254. The cost difference between Abon Surya and the EOQ method is IDR 78,386,417. This shows that there is a saving or reduction in the total cost of inventory needed if Abon Surya can implement the EOQ raw material control method. Apart from that, the packaging used at UMKM Surya Abon for shredded products still uses transparent plastic with stickers, which is less attractive to buyers. Therefore, a new design is needed to attract more buyers.

PT XYZ is a company that has been engaged in metal casting for a long time. This company produces products in the form of wingnut spare parts. The production system used is make to order production. The obstacle faced by PT XYZ was that it was found that the setup operation process activity took quite a long time on average 40 minutes. If it continues to occur it will have an impact on delays. With these problems, PT XYZ reduced the setup time to overcome delays in completing the automatic molding machine wingnut product. Utilize the Single minute exchange of die (SMED) method to speed up setup. The SMED approach distinguishes between internal regulatory and external regulatory activities. Adjustment activities that only Internal adjustments can be made while the machine is stopped. The External Setup setup activity can be performed while the machine is running or operating. By switching to external setup instead of internal setup, setup tasks that were completed when the machine was stopped can now be completed while it is running, thereby reducing setup time. the setup operation of all these activities is carried out when the engine is off or the internal setup produces an average of 101 molds. Meanwhile, the setup time after implementing SMED can be reduced to 26.78 minutes or a decrease of 47.61%. This decrease in setup time increases productivity by 2 molds/day and if in a month with 26 working days it can add 59 molds so that in total it can produce 159 molds/month.
