Analisis Perbandingan Metode Single Moving Average, Single Exponential Smoothing dan Naive Model (Kasus: Peramalan Penjualan Bahan Bangunan)
ABSTRAK
Peramalan penjualan sangat penting dalam menentukan persediaan stok produk sehingga penelitian ini bertujuan membandingkan hasil dari peramalan menggunakan metode single moving average, single exponential smoothing dan naive model untuk membantu toko cahaya 99 menyediakan stok periode yang akan datang. Pada pengolahan data untuk single moving average diselesaikan dengan pergerakan 3, single exponential diselesaikan dengan alpha 0,3 serta naive model diselesaikan dengan nilai dari hasil penjualan sebelumnya. Adapun hasil uji akurasi ketepatan peramalan penjualan dengan nilai MAPE yang memiliki interpretasi Baik pada kelima produk tersebut ialah Single Exponential Smoothing sehingga dapat disimpulkan bahwa metode ini lebih optimal dibandingkan dengan kedua metode lainnya yaitu Single Moving Average dan Naive Model.
Kata Kunci: Analisis, Single Moving Average, Single Exponential Smoothing, Naive Model, Peramalan
ABSTRACT
Sales forecasting is crucial in determining product stock inventory. Therefore, this study aimsto compare the results of forecasting using the single moving average, single exponential smoothing, and naive model methods to assist "Toko Cahaya 99" in preparing stock for upcoming periods. In processing the data for the single moving average, a 3-period moving average was utilized. The single exponential smoothing was performed with an alpha value of 0.3, while the naive model was completed using the previous sales figures. The accuracy test results, measured by Mean Absolute Percentage Error (MAPE), indicated that the sales forecasting precision was "Good" for all five products using the Single Exponential Smoothing method. Thissuggeststhat this method is more optimal compared to the othertwo methods, namely Single Moving Average and Naive Model.
