Abstract

Indonesia is an agricultural country that relies heavily on agriculture, especially the production of rice as a staple food. The government has an important role in maintaining food security through the Logistics Affairs Agency (BULOG). Perum BULOG must anticipate uncertainty in rice demand and ensure sufficient stock. Fuzzy logic methods, especially the Mamdani Method, are used to optimize rice supplies. This research is a quantitative approach with descriptive methods, describing the characteristics of the research object without relationships or comparisons with other variables. Fuzzy logic methods, especially the Mamdani Method, are used to optimize rice supplies. This research aims to apply the Fuzzy Mamdani Method in determining the amount of rice inventory at Perum BULOG on Jl. Asahan.The centroid method is used to calculate z values ​​based on the results of rule aggregation. So, the z value (inventory) based on the Mamdani method with input x 10044820 and y 936000 is 805086. The results of this defuzzification indicate that inventory is "High" at a level of around 805086. The Mamdani method produces rice supplies of around 805,086 kg based on income and distribution. Uncertainty related to fluctuations in income and distribution.

Abstract

The aim of this research, based on the problem formulation above, is to find out that inventory management by using the Ecolnolmic Order Quantity (EOQ) met mode can minimize the total inventory costs UMKM Home Industry Rumah Tempe Asli HB Pematangsiantar. This thesis research uses a quantitative descriptive method. The method used in controlling tempe goods inventory is the EOQ method. The EOQ method is a inventory management technique carried out by the company by determining the most efficient inventory amount of goods and producing balanced processing costs and storage costs, so that The company can minimize inventory costs. From the results of research using the EOQ method, the total inventory carried out with the EOQ metdown is 80.179 pcs with a purchase frequency of 22 times. The amount of security stock required by UMKM Home Industry Rumah Tempe Asli HB Pematangsiantar is 8.200 pcs. Total inventory using the EOQ method is IDR Rp1.122.421. EOQ meting can reduce the costs of providing merchandise more or can be said to be efficient if applied to UMKM Home Industry Rumah Tempe Asli HB Pematangsiantar. In other words, the inventory control carried out by the company is still not yet optimal. By using the EOlQ met mode in managing mobile inventory, Rumah Tempe Asli HB can optimize the cost of mobile inventory.

Abstract

Inventory is one of the most important things in a company, especially in the hospital industry, in providing drug supplies in order to provide good services. So inventory contro is needed to avoid running out and excess stock of drugs. The aim of this research is to find out the grouping of drugs based on their investment value, find out the optimum order quantity for each drug and find out the time to order each drug. The research method used by researchers uses quantitative methods, ABC, EOQ and ROP analysis methods. This research was conducted at RSUD Dr. Djasamen Saragih Pematangsiantar. From the research resuts, the ABC analysis method shows that 14 types of group A drugs (23.3%) use a budget of 69% of the total drug budget usage, 13 types of group B drugs (21.7%) use a budget of 22%. Of the total use of the drug budget and types of group C drugs, 33 types (55%) use a budget of 9% of the total drug budget use. By analyzing the Economic Order Quantity (EOQ) method, the optimum number of drugs was obtained for group A from 31-2,651 items, group B starting from 6-2,438 items and group C starting from 8-5,527 items. Meanwhile, with ROP analysis, the drugs reordered for group A range from 16-851 items, group B starts from 1-398 items and group C starts from 1-819 items.
