Metode Material Requirement Planning (MRP) dalam Perencanaan Produksi Sirup Markisa Dewi

Abstract

Production planning is very important in a company. In this research the author used the Holt Winter Multiplicative Method which aims to predict the demand for passion fruit syrup in 2024 and the Silver Meal Algorithm method which can minimize ordering costs and storing costs for passion fruit and sugar at PT. Dewi Berastagi Passion Fruit Syrup. Based on calculations and data processing, the forecast results obtained for the demand for passion fruit syrup were 87,751 liters with raw materials for passion fruit amounting to 175,502 kg and sugar amounting to 87,751 kg. Based on the Material Requirement Planning (MRP) method and the lot sizing technique used in this research is the Siver Meal Algorithm because it has a total ordering cost and holding cost that is smaller than the Wagner Within Algorithm. The total cost of ordering passion fruit is IDR 6,600,000 and sugar is IDR 9,000,000. Storage costs for sugar and passion fruit are 0. Total costs are IDR 15,600,000 and total costs from company policy are IDR 42,649,400 or savings of IDR 27,049,400 (63.42%). Orders using the Silver Meal Algorithm method are made in each period, namely during 1 year 12 orders are
