Abstract
Bagian awal dari suatu proses pengambilan suatu keputusan pada persoalan disebut peramalan. Model eksponensial smooting direkomendasikan sebagai sebuah teknik yang tidak kompleks dan ekonomis (inexpensive method), digunakan time series , analisis metode causal, analisis perhitungan koefisien korelasi, menggunakan variabel tingkat inflasi, Indeks Harga konsumen Kota X menggunakan pengukuran kesalahan Mean Square Error (MSE) dan Percentage Error (PE). Didapati dengan time series error untuk tingkat inflasi MAPE 1,242 dan PE 26,31 secara siklis, untuk Indeks Harga Konsuen MAPE 6,23 dan PE 39,05 secara siklis, untuk indeks pembangunan manusia MAPE 44,42 dan PE 32124,33 dengan Linear. .Pada metode kausal peramalan penjualan pada tahun 2019 adalah 1.672.373 unit, penjualan peramalan dengan indeks 0,094 terjadi pada bulan April, peramalan penjualan pada tahu 2020 adalah 1.696.534 unit, penjualan peramalan dengan indeks 0,094 terjadi pada bulan April. Perhitungan koefisien korelasi tingkat inflasi -0,107, indeks harga konsumen 0,157, dan Indeks Pembangunan Manusia 0,978.
Part of a decision making process of problem is forecasting. Exponential smooting model is recommended as a technique that is not Forecasting is complex and economical (inexpensive method), the method used is time series , causal analysis method, analysis of correlation coefficient calculation, using variable inflation rate, consumer price index, city inflation rate Pare-Pare Using measurements Error Mean Square Error and Percentage Error. Found with the time series error for the MAPE inflation rate 1.242 and PE 26.31 cyclically, for the MAPE Consumption Price Index 6.23 and PE 39.05 cyclically, for the MAPE human development index 44.42 and PE 32124.33 with Linear.On the causal method sales in 2019 was 1,672,373 units, forecasting sales with an index of 0.094 occurred in April, sales in 2020 was 1,696,534 units, forecasting sales with an index of 0.094 occurred April. Calculation of the correlation coefficient of the inflation rate of -0.107, the consumer price index of 0.157, and the Human Development Index of 0.978
