Industri jasa makanan dan minuman merupakan industri yang popular seiring dengan berkembangnya gaya hidup praktis. Tantangan yang dihadapi adalah mengatur aliran bahan, menjaga kualitas serta mencermati jumlah persediaan bahan baku. Waroeng Spesial Sambal "SS" sebagai salah satu pelaku industri jasa makanan dan minuman memiliki permasalahan dalam menyediakan bahan baku sebelum jam buka warung untuk menghindari stockout. Hal ini dikarenakan sistem perencanaan penjadwalan distribusi bahan baku masih dilakukan secara manual dan menunggu informasi bahan sisa dari setiap cabang. Penelitian ini menggunakan Metode Distribution Requirement Planning (DRP) sebagai metode usulan untuk mengatasi masalah yang dihadapi Waroeng Spesial Sambal "SS" tersebut. Metode forecasting yang digunakan adalah Exponential Smoothing dengan konstanta penghalusan 0,5, dan metode untuk Lot Sizing adalah Wagner-Whitin. Perhitungan baik peramalan maupun lot-sizing dilakukan dengan bantuan software POM-QM (Quantitative Methods, Production and Operations Management). Berdasarkan hasil penerapan metode DRP untuk penjadwalan distribusi 5 bahan baku di 6 cabang Waroeng Spesial Sambal "SS" Yogyakarta, terjadi penghematan total biaya distribusi sebesar Rp. 629.571,- atau 49,91%. Hasil tersebut memberikan kesimpulan bahwa metode DRP dinilai memiliki performa yang baik dan berpotensi untuk diterapkan di Waroeng Spesial Sambal "SS".

Distribution Requirement Planning is a new method that's being used at this paper to solve the distribution issues of Waroeng Spesial Sambal "SS" , with Exponential Smoothing method for the forecasting, and Wagner-Whitin for the lot-sizing problem. The calculation of forecasting and lot-sizing is done by POM-QM software (Quantitative Methods, Production and Operations Management). The implementation of Distribution Requirement Planning (DRP) method to calculate distribution schedule of 5 raw materials in 6 outlets resulted in 49,91% or Rp. 629.571 reduction of the total distribution cost. In conclusion, the DRP method could provide positive impact in the distribution department of Waroeng Spesial Sambal "SS".
