Abstract

In most researches in the area of risk management, the result stops at proposing the mitigation strategies. The number of researches on associating cost analysis into the risk management process is very limited. This paper proposes a practical process on how cost analysis can be associated into the risk management process especially in the area of manufacturing. The process of the risk management is conducted as usual, started by selecting the potential risk and finding the major causes. Then, a risk map and its rubric of risk likelihood and severity are developed, and the major causes are plotted into it to select the priority of the major causes and the proposed mitigation strategy is developed. Then, the poposed strategy is compared with the current strategy based on the cost generated using the developed equation. The result shows the proposed mitigation strategy is selected because it saves approximately IDR 2 million per order. It indicates that cost analysis can be successfully associated into the risk mitigation process and generates a comprehensive recommendation to the decision maker.

Abstract

PT. XYZ is a food and beverage company in Indonesia which produces many kinds of products with several different packing size since 1979. PT. XYZ always strives to improve production efficiency, especially in minimizing waste and loss that occur in every process of production. This study was conducted to calculate the Overall Equipment Effectiveness (OEE) of packaging machines at line 2 of PT. XYZ and identify the cause of the loss and waste that exist during production process. Overall Equipment Effectiveness (OEE) is a method to evaluate how effectively a manufacturing operation is utilized. The result of this research indicated that the OEE percentages of packaging machines both Weighing and SVB do not meet the company’s standards, which is 80 %. The main factor causing the declining value of OEE is machine availability and it is happened because the machine operator takes a long time to set up the machine.
