Abstract

PT. INF is a steel mining company. It produce such as nickel pig iron. Nickel pig iron used raw materials stainless steel factory, nickel and steel mill rolls. The number of defective products for nickel pig iron in a few months getting on upward trend. This research will analyze the cause of the increasing defect product by using Six Sigma methode. Furthermore, the proposed improvement is done by using the failure mode and effect analysis (FMEA) approach. The results shows the main problems are the higher value of Silica (Si) and phospor (P), the sigma level is obtained from the annual pig iron making process in 1.6 sigma, process improvement need to be done are monitoring and scheduling of burnlime powder orders, checking new materials by testing the formula against new materials, and making a repair schedule as well as focusing on changes in pressure on the monitor screen

Abstract

The purpose of this study is to measure the value of the bullwhip effect, identify its causes, and find solutions to reduce it. The problem of the bullwhip effect, where their order fluctuations exceed demand fluctuations, resulting in raw material shortages and production stops. This study examines two echelons in the supply chain and uses the FMEA method. The results showed that the bullwhip effect value at echelon 1 (supplier and PPIC) was 1.66, while at echelon 2 (PPIC and Customer) was 0.63. This indicates the presence of a bullwhip effect at echelon 1, while echelon 2 is not affected. Some of the main causes of the bullwhip effect include raw material procurement not meeting orders, material price increases, uncertainty in demand information, large raw material orders and sales volumes greater than raw material receipts. solutions that can be done between suppliers need to implement an information system using E-commerce such as shopee in order to further expand the marketing network and facilitate product distribution to consumers so that online ordering
