Abstract

Mitsubishi Chemical Indonesia is a producer of Purify Terepthalic Acid (PTA) in Indonesia with an important role in meeting the primary needs of the Indonesian population by managing raw materials to produce purified terepthalic acid. Purified terepthalic acid is the main raw material for polyester fiber. The problem that occurs is the phenomenon of the bullwhip effect, namely the occurrence of fluctuations between orders and demand which results in a shortage of raw materials or low inventory which can cause production to stop. So the purpose of this study is to calculate the value of the bullwhip effect, determine the causes of the bullwhip effect, and determine solutions to reduce the bullwhip effect. This study begins by calculating the value of the bullwhip effect at the two echelons. The method used in this research is FMEA. The results of this study are the value of the bullwhip effect at echelon 1 (suppliers and PPIC) = 1.27 and echelon 2 (PPIC and distributors) = 0.93. This value indicates the occurrence of a bullwhip effect in echelon 1 while echelon 2 does not indicate the occurrence of a bullwhip effect. The dominant causes of the bullwhip effect are market competition, rising material prices, demand forecasting that is not close to accurate and the number of orders for raw materials in large quantities. The proposed improvement is to collaborate with suppliers and customers to get guaranteed orders and demand that are fixed and sustainable.

Abstract

Inventory is an important factor in carrying out a production. Many companies experience problems in terms of inventory control, one example is inventory scarcity. The purpose of this study is to optimize the need for goods so that the company will not experience problems with inventory shortages or inventory buildup. This study uses the Min-Max method by collecting data in the form of inventory of goods needs, ordering costs, and storage costs. The result of this study is that the safety stock value of 80,887-tons is useful for protecting and anticipating inventory shortages, so companies must be on guard when they are at that value. Then, the Reorder Point value was obtained at 108,165 tons. Furthermore, the value of the Minimum Inventory is 269,879-tons and the Maximum Inventory is 378,044-tons so that companies are not recommended to have more inventory than that value.

Abstract

The development of food commodities in Banten province, with geographical conditions where the area is mostly agricultural and with a fairly large population, has an important role, one of which is as a food buffer on the island of Java. Many harvests are distributed directly outside the region, after which they enter the market through distributors and agents, so this is a point of weakness and deficiency for policy makers in regulating and distributing rice commodities. This research was conducted with the aim of knowing the rice distribution model using the Powersim application. The method used to create a food policy model/design for Banten province is the Dynamic System. The results of this research are that the output obtained from the rice food distribution model simulation is that each rice stock in the Gapoktan warehouse sends according to the amount requested in each district/city, with a total capacity that can be obtained at the food distribution center of 109,682 tonnes/yr, or 2,742 tons/harvest. Then, after carrying out a simulation model using Powersim software, it can be concluded that the rice food commodity in Banten Province can still meet demand. With the Banten Province Food Distribution Center, it can control the availability of rice.

Abstract

Honda Auto Serang is a car sales and maintenance company in Serang City. As car sales increase, the need for vehicle maintenance and repairs will also increase. Therefore, it is necessary to analyze the vehicle repair process queue system at the workshop. The analysis was conducted using Arena Software to determine the condition of the existing queue system and suggestions for improvements that can be provided to reduce the waiting time for the repair process. By organizing the repair process flow, providing complete work equipment and arranging spare part collection, the average waiting time for service advisors in the queue system on weekdays decreased from 21 minutes to 25 minutes in scenario 1 and 15 minutes in scenario 2. The average waiting time for service queue customers on weekdays was 97 minutes, reduced to 81 minutes in scenario 1 and 83 minutes in scenario 2.
