Implementasi Model Persediaan Q Probabilistik dalam Perencanaan dan Pengendalian Persediaan Bahan Baku Produksi Teh Botol Sosro

Abstract

PT. Sinar Sosro is a beverage manufacturing company. One of the products of PT. Sinar Sosro, which is known and much sought after by the general public, is Teh Botol Sosro. The uncertain demand for Teh Botol Sosro causes the supply system to be uncontrolled, so that market demand is not met. To overcome this problem, the author uses the Holt-Winters Exponential Smoothing method which aims to predict the need for raw materials for tea and sugar in order to meet production needs in the future, and to minimize raw material inventory costs, the Continuous Review System method is used. Based on the results of calculations using Holt-Winters Exponential Smoothing, the demand for tea is 45,612.88 kg and sugar is 651,538.81 kg in one year of use. And based on the results of calculations using the continuous review system method, the total cost of tea supplies is Rp. 2,813,404,544 where r=2.331,65 kg and q=3.462,98 kg. And also obtained the total cost of sugar supplies Rp. 7,253,604,988 where r=28.453,95 kg and q=53.341,93 kg. So that the company can save about 6.35% and 4.44% of the total cost of supplying raw materials for tea and granulated sugar based on company policy
