Penerapan Statistical Straight Line Method Pada Sistem Pendukung Keputusan Prediksi Harga Pangan

Abstract

<em><span lang="IN"> The existence of fluctuating food price changes can cause losses for both producers and consumers. For that, we need a method that can predict prices within a certain period of time. One method that can be used is the Statistical Straight Line method. The purpose of this study is to predict food prices within the next 1 month and 1-year using training data. To test the accuracy of price predictions, Mean Absolute Percentage Error (MAPE) is used with the actual value. The calculation results show that prices that change in value that are not drastic each month have a MAPE value of less than 10%, while prices that change drastically every month have a MAPE value greater than 10%.</span></em>
