Two days Training for Advances in Applied Nickel Price Forecasting. The in-house training was held at PT. AKA Geosains Consulting from 20 – 21 May 2025. The modules described the quantification of global nickel supply & demand. The Herfindahl-Hirschman Index (HHI) and Global Supply Concentration (GSC) approaches have been introduced that appeared to support the nickel as the concentrated production. The concentrated products were influenced by Indonesia, therefore Indonesia has played a critical role to influence the global nickel market. This course also discussed the quantitative forecasting methods that was started from the statistical (normality, stationarity and homoscedasticity) and econometrical analysis (correlation and cointegration). Then, the time-series was examined to identify the existence of trend, cycle and bubble. The trend, cycle and bubble were tested using Kendal’s tau method, the Weinbull distribution and the total present value model, respectively. The results of statistical, econometrical and time-series tests have suggested the best methodology in forecasting the nickel prices. This course applied the artificial neural network (ANN) model and the metaheuristics methods to optimize the forecasting.
