Abstract
Kepuasan pelayanan pasien merupakan indikator kinerja yang baik pada Rumah Sakit, salah satu yang berperan penting adalah pelayanan logistik makanan. Dengan jumlah pasien yang fluktuatif, Rumah Sakit harus mampu memenuhi permintaan jumlah pasien setiap hari. Penelitian ini bertujuan untuk membangun sistem peramalan dan pengendalian persediaan makanan untuk menentukan jumlah porsi makanan yang harus tersedia pada hari berikutnya. Jumlah bahan baku makanan dikendalikan dengan menggunakan model re-order point, yang bertujuan untuk mengantisipasi terjadinya kekurangan persediaan. Data diperoleh dari jumlah permintaan makanan selama 212 hari untuk tiga waktu, pagi, siang, dan malam hari. Nilai pemulusan dan peramalan menggunakan parameter alpha 0,3 dan 0,7 dengan perhitungan kesalahan peramalan minimal menggunakan MAPE untuk alpha 0,7 sebesar 12,81% untuk waktu pagi, 11,59% waktu siang, dan 10,96% waktu malam. Hasil peramalan tidak hanya dapat digunakan untuk mengalokasikan porsi makanan namun juga dapat mengendalikan persediaan bahan baku. Kata kunci : Forecasting Method, Exponential Smoothing, Re-Order Point The satisfaction of patient care is an indicator of good performance in hospitals, one of which plays a critical role is a logistic serving of food. With the fluctuating number of patients, the hospital should be able to meet the demand for the number of patients each day. This study aims to build the system of forecasting and controlling the food supplies to determine the number of servings of food supplies in the next period. The implementation of Exponential Smoothing method is used to predict the number of servings should be available for the next period. Amount of food raw material is controlled using re-orders point model, it aims to anticipate the occurrence of stockout with the minimum amount of food provides should be available. The data were obtain ed from the requested amount of food during 212 days for three times, morning, noon, and night. Forecasting values using alpha parameters 0.3 and 0.7 with a minimum forecasting error calculation using MAPE for alpha 0.7 with a value 12.81% for morning time, 11.59% during the day, and 10.96% night time. Forecasting result not only can be used to allocate food supplies but also to control stock of raw material food. Keywords : Forecasting Method, Exponential Smoothing, Re-Order Point
