Abstract

PT. X is a company that manufactures electronic equipment such as refrigerators, washing machines, televisions, and other products. This research was conducted only focusing on the refrigerator division. The refrigerator division has problems in the upstream supply chain. Therefore, companies need a measurement of the performance of Supply Chain Management (SCM). The purpose of this study is to measure the performance of SCM to find out indicators that are still far below the target and provide recommendations for improvement. SCM performance measurement is done by SCOR method for process decomposition, AHP for KPI hierarchy weighting, and OMAX for scoring system. The results of the research that have been analyzed with the Traffic Light System indicate that there are 9 KPIs from 22 valid KPIs that have never been in the green category. The total index results of the overall supply chain performance show that the lowest performance is in December 2017 with a total index of 3.5934 and the highest is in March 2018 with a total index of 7.002. There are 10 KPIs in the red and yellow categories in December which should be given more attention. Improvement recommendations are given to indicators that have never been in the green category. For example recommendations, DRS 2.3 KPI (supplier response speed in response to late arrival of raw materials at the factory) in improving its performance needs to do tracking of raw material shipments and additional shipping fleets or suppliers from suppliers.

Abstract

Today PT. Jakarta Pertamina Unit Produksi Pelumas Jakarta (UPPJ) has some problems with inbound supply of raw materials. Deficiency dock may pose risks to the process of loading raw material base oil, resulting in delay in supply of raw materials. This delay could have an impact on other processes, such as delays to produce, and iddle of existing production facilities at the plant; it would be very detrimental to the company if the obstacle is often the case. Supply chain management is always influenced by three factors, namely how to reduce costs, reduce time and improve quality. If at first study on supply chain management is only classified in three categories, namely the field of operations, design and strategy, then this can be added to the four categories, namely the field of risk, which is commonly referred to as supply chain risk Management (SCRM). Based on the problems that occurred the first stage done is to identify risks in each process and then determine the influence of the effect in terms of cost, time and quality of the results of the determination of the influence. the next step is to determine the weights based on the severity of the bottleneck (severity), the possibility of resistance (Occurrence) and the possible causes of the barriers can be detected (Detection). The last step is to calculate the Risk priority Number (RPN) is obtained from the product of severity, Occurrence and Detection then obtained the highest priority for 144 the factors that most influence the leak rate of the production process.
