Trade Price atau juga dikenal sebagai harga pasar adalah harga perdagangan suatu komoditas yang saat ini dijual di pasar. Model ARIMAX merupakan model ARIMA dengan variabel tambahan exogen atau variabel prediktor. Dalam penelitian ini, variabel eksogen yang digunakan adalah kapasitas import komoditas minyak nabati di Indonesia. Hasil peramalan Trade Price Komoditas Minyak nabati di yang tercatat di perusahaan komoditas pangan dengan variabel dummy waktu terjadinya Covid-19 diperoleh model terbaik adalah model ARIMAX(1,1,0). Hasil peramalan Trade Price Komoditas Minyak nabati di perusahaan komoditas pangan dengan variabel prediktor kapasitas import minyak nabati di Indonesia diperoleh model terbaik adalah model fungsi transfer dengan orde b,s,r (0,0,0). Hasil peramalan Trade Price Komoditas Minyak nabati di perusahaan komoditas pangan pada periode Juli-Desember 2020 relatif stabil dengan harga Trade Price Komoditas Minyak nabati sebesar 980 US Dollar. ================================================================================================ Every market participant must always be ready with accurate information regarding the estimated price of food commodities in the market.
