Abstract

Overload is a condition where the goods stored in the warehouse exceed the existing capacity. With the accumulation, it will increase the storage cost for the products/goods stored. The purpose of this research was to help companies determine the optimal amount of production, optimal production time intervals and maximum product inventory so that there is no excess stock of products in the warehouse, and to obtain a minimum total inventory cost by using the Economic Production Quantity (EPQ) model. To collect the data needed in this study, secondary data was used which consists of production data and product delivery of company X. From the research results, the optimal production rate (Q*) is 13,646 MT/production cycle with an optimal production time interval of 1.16 months. or equal to 35 days, the maximum amount of inventory (Imax) was 429 MT. The total minimum inventory cost in one production cycle/month is Rp.167,925,698.28, -. The difference in total inventory costs generated using the EPQ method and calculations based on company conditions is 9% or equivalent to Rp.16,538,501, -. Based on the results of the sensitivity analysis it was known that all parameters are sensitive to Q*, Imax, and total inventory costs. However, a significant change is the parameter of saving costs, where the increase and decrease in saving costs will decrease and increase Q*, Imax, and the total cost of inventory

Abstract

The company runs a business by providing services related to storage and handling of goods in warehouses to its customers, namely PT Semarang Autocom Manufacturing Indonesia Jepara (SAMI-JF) and Tugu (SAMI-TF). Goods from SAMI-JF and SAMI-TF customers have similarities so that checkers often have difficulty identifying and finding items to be inspected. This causes delays in checking goods in the inbound inspection area, resulting in a delay in the putaway process. This study aims to provide suggestions for improving the placement of goods in the inbound inspection area in the logistics warehouse. The method used is the Class Based Storage method. Based on data processing, the results of the proposed improvements are the location of goods placement in the logistics warehouse divided into two groups, namely groups A and B. Goods from SAMI-JF customers use the area from block 1 to block 19, while goods from SAMI-TF customers use blocks 20 to 38 blocks with a total distance of 2593.5 m. The results of the proposal are expected to reduce the occurrence of delays in checking goods in the inbound inspection area and completing putaways

Abstract

PT. X is a company engaged in the production of electrical and electronic equipment, one of its products is camera. This research aims to compare the inventory policies that have been implemented by the company with other dynamic deterministic models. In the production process, the company uses a stock policy with the Lot for Lot (LFL) method, but the total costs incurred by the company and the frequency of ordering are still quite high. This research aims to compare the inventory policies that have been implemented by the company with other dynamic deterministic models, such as Period Order Quantity (POQ) and Economic Part Period (EPP) methods so that the optimal inventory method can be determined. The results of this study indicate that the Economic Part Period (EPP) is the optimal method with a total cost of Rp. 69,284,600 and the order frequency is 7 times

Abstract

In a warehouse facility layout design including a health clinic, the layout design of warehouse facilities and production storage areas plays a very important role, it is impossible for the manufactured goods to be distributed directly to all customers. For this reason, there is a need for a good storage area and storage system to simplify the production process. Clinic XYZ is a 24-hour public health clinic, located in a sub-district in North Sumatra, to be precise in Medan Deli District. The problem that occurs is the random arrangement of goods in the warehouse without paying attention to storage and arrangement patterns that depend on the position of the empty warehouse. Based on observations, it is known that the time span needed to look for drugs at the clinic is too long, so this will make it difficult for employees / operators to manage the products to be stored or retrieved from the drug warehouse. One of the warehouse design methods that can be used is the dedicated storage method. Dedicated storage is a method of placing a specific location or storage area for each item stored. In this study, the types of drugs were classified into drugs, solid types of drugs, semi- solid drugs, liquid drugs and gas drugs. Based on the results obtained, the number of slots needed in the drug product warehouse is 11 slots, the total floor area needed is 13.2 m2, the area needed for storing medicinal products with an alley area is 6.8 m2, the percentage of area that is not used for storage the product in the medicinal product warehouse is 34% and the diagonal length of the hand truck when carrying the box is 1.56 m

Abstract

PT. X is an industry that produces green tea and black tea. In this study, there are often problems with the wrapping machine due to the age of use and the tight schedule of usage in the wrapping machine. If the machine operates in an unstable condition, it will greatly affect the results of the production. Damaged components such as cutting blades, heating heaters, thermo control and bearings. By using the Failure Mode and Effect Analysis (FMEA) method and also calculating the Risk Priority Number (RPN) value, the highest RPN value to the lowest is obtained, namely Cutting Knife (RPN = 100), Heater (RPN = 90), Thermo Control (RPN = 72) and Bearings (RPN = 36). It can be seen that the cause of damage to the wrapping machine and also the highest RPN calculation is found in the damage to the cutting knife whose RPN value is 100. From the analysis of the damage to the cutting knife, the author provides a suggested repair plan for the company so that it can be implemented in the company which can later improve the quality of the machine to be operated. for the future which cannot be separated from the supervisory role of the operators in charge of their cooperation to improve quality and the quality control team that always monitors quality
