Abstract


Abstract: PT. Alam Jaya Wirasentosa which is located in Hessa Air Genting, Air Batu District, Asahan Regency, North Sumatra. This company is engaged in sales and distribution which has a fairly wide coverage on the island of Sumatra. PT. Alam Jaya Wirasentosa sells Indofood's main products, one of which is bimoli cooking oil. Constraints experienced by PT. Alam Jaya Wirasentosa often has problems with stock availability due to the large number of product requests from consumers. In addition, there are times when there is too much inventory (over stock) that results in too high a cost burden to store and maintain materials during storage in the warehouse even though the goods still have opportunity costs (funds that can be invested / invested in more profitable things). In this study, the SMA method is used to solve the problem of predicting the demand for cooking oil in the next period. In addition, the purpose of this study is to determine the forecasting system used by PT. Alam Jaya Wirasentosa in forecasting the demand for Cooking Oil each month and implementing the Single Moving Average Method in forecasting the Demand for Cooking Oil, especially Bimoli cooking oil. At PT. Alam Jaya Wirasentosa.

 

Keywords: Forecasting; Single Moving Average; Bimoli Cooking Oil; PT. Alam Jaya Wirasentosa

 

 

Abstrak: PT. Alam Jaya Wirasentosa yang berlokasi di Hessa Air Genting, Kecamatan Air Batu, Kabupaten Asahan, Sumatera Utara.Perusahaan ini bergerak dalam bidang penjualan dan distribusi yang memiliki cakupan cukup luas di pulau Sumatera. PT. Alam Jaya Wirasentosa menjual produk utama Indofood salah satunya minyak goreng bimoli. Kendala yang dialami oleh PT. Alam Jaya Wirasentosa sering mengalami masalah ketersediaan stock barang dikarenakan banyaknya permintaan produk dari konsumen. Selain itu ada masa dimana terlalu banyaknya persediaan (over stock) yang ada sehingga mengakibatkan terlalu tingginya beban biaya guna menyimpan dan memelihara bahan selama penyimpanan di gudang padahal barang tersebut masih mempunyai opportunity cost (dana yang bisa ditanamankan / diinvestasikan pada hal yang lebih menguntungkan). Pada penelitian ini menggunakan metode SMA dalam memecahkan masalah prediksi permintaan minyak goreng pada periode selanjutnya. Selain itu tujuan penelitian ini adalah untuk mengetahui sistem peramalan yang digunakan oleh PT. Alam Jaya Wirasentosa dalam meramalkan permintaan Minyak Goreng tiap bulannya dan mengimplementasikan Metode Single Moving Average dalam meramalkan Permintaan Minyak Goreng khusunya minyak goreng Bimoli Pada PT. Alam Jaya Wirasentosa.
