Abstract

ABSTRAK iv PT Darya-Varia Laboratoria Tbk merupakan industri farmasi. Persediaan bahan baku produk Vicee Jeruk terjadi kondisi jumlah persediaan bahan baku mendekati stok out. Masalah yang dihadapi adalah ketidakpastian dalam menentukan jumlah pembelian bahan baku yang optimal dan keterlambatan pemesanan bahan baku. Penelitian ini bertujuan menganasilis jumlah pembelian bahan baku yang paling optimal dengan menggunakan metode EOQ untuk menganasilis ROP persediaan bahan baku dalam mencapai kelancaran produksi. Penelitian bersifat kuantitatif dengan metode pengumpulan data yaitu wawancara, dokumentasi dan observasi. Analisa awal yang dilakukan dengan metode peramalan permintaan dengan membandingkan nilai error dan selanjutnya membandingkan nilai error terkecil. Dari hasil penelitian metode peramalan yang tepat adalah metode single exponential smoothing (α=0,9).Pemesanan yang optimal bahan baku fruit mix sebanyak 4.5 kg, SS sebesar 5 kg, ROP sebesar 14.4 kg dan TC sebesar Rp. 17.670.833. Bahanbaku ethyl matol sebesar 1.6 kg, SS sebesar 5 kg, ROP sebesar 8.8 kg danTC sebesar Rp. 18.816.000. Bahan baku alkohol 95% sebesar 2.8 kg, SS sebesar 5.2kg, ROP sebesar 13.4 kg dan TC sebesar Rp. 23.081.142. Kata kunci : Stock out, Peramalan, EOQ, SS, ROP http://digilib.mercubuana.ac.id/ ABSTRACT v PT Darya-Varia Laboratoria Tbk is a pharmaceutical industry. Inventory of raw materials for Vicee Jeruk product occurs when the amount of raw material inventory is close to out of stock. The problemsfaced are uncertainty in determining the optimal amount of raw material purchases and delays in ordering raw materials. This study aims to analyze the optimal amount of rawmaterial purchases using the EOQ method to analyze the ROP of raw material inventory in achieving smooth production. The research is quantitative with data collection methods, namely interviews, documentation and observation. The initial analysis is carried out by the demand forecasting method by comparing the error values and then comparing the smallest error values. From the research results, the correct forecasting method is the single exponential smoothing method (α = 0.9). The optimal orderforfruti mix rawmaterial is 4.5 kg, SS is 5 kg, ROP is 14.4 kg and TC is Rp. 17,670,833. Ethyl matol raw material is 1.6 kg, SS is 5 kg, ROP is 8.8 kg and TC is IDR. 18,816,000. Raw material for 95% alcohol was 2.8 kg, SS was 5.2 kg, ROP was 13.4 kg and TC was Rp. 23,081,142. Keywords: Stock out, Forecasting, EOQ, SS, ROP
