Gold is a valuable value that can help to stabilize the currency in the country. However, there are a few factors that can shift the Gold price. From the previous researcher, they had identified that macroeconomics had influenced the gold price changes. The objective of this study is to identify the primary macroeconomics factors that impact gold price changes. The macroeconomics factors involve the Inflation Rate, Gross Domestic Product, Exchange Rate, and Crude Oil Price. The method that had been applied in this study is Fuzzy logic. For this method, three gold experts were chosen to complete the inference system rules to complete the inference system in Fuzzy Logic. The inputs are microeconomic factors, and the output is Gold Price. The highest output had been chosen to identify which factors that involve in the gold price change.
