Abstract

Abstract. Hospital inventory management play a very significant role in hospital's performance. Too much inventory wiil lead to excessive inventory cost but too low inventory might result in dissatisfactions of patiens and lack of performance of physicians or doctors. Economic order Quantity (EOQ) is an inventory control method that can help hospital to minimize total inventort cost. However, managers might find difficulties in deterimining the right amount of ordering and holding cost which are needed in calculating EOQ. This research is a case study from a class “A” specialized hospital. Inventory data of pharmaceutical items are calculated to measure the sensitivity of changes in ordering and holding cost to average inventory level which will lead to understock or overstock. Different ordering cost and holding cost will lead to different proportion of overstock and understock but will not give a significant differences. This research recommend EOQ model to be used in hospital inventory management inspite of the difficulty and hesitation of hospitals to estimate ordering and holding cost.Keywords: Economic order quantity, sensitivity analysis, hospital inventory management, overstock, healthcare inventory management, holding cost, ordering cost, fixed order quantityAbstrak. Manajemen persediaan rumah sakit memainkan peran yang sangat penting dalam kinerja rumah sakit. Terlalu banyak persediaan akan menyebabkan biaya persediaan meningkat, namun persediaan yang terlalu rendah juga bisa mengakibatkan ketidakpuasan pasien serta rendahnya kinerja pelayanan dokter kepada pasien. Economic Order Quantity (EOQ) adalah metode pengendalian persediaan yang dapat membantu rumah sakit untuk meminimalkan biaya persediaan total. Umumnya manajer menemukan kesulitan dalam menentukan biaya pemesanan dan biaya penyimpanan yang dibutuhkan dalam menghitung EOQ. Penelitian ini merupakan studi kasus dari rumah sakit khusus kelas A. Data inventaris barang farmasi dihitung untuk mengukur sensitivitas perubahan dalam pemesanan dan biaya penyimpanan terhadap tingkat persediaan rata-rata yang akan menyebabkan kondisi understock atau overstock. Biaya pemesanan dan biaya penyimpanan yang berbeda akan menghasilkan proporsi overstock dan understock yang berbeda namun tidak akan berbeda secara signifikan. Penelitian ini menyarankan penggunaan model EOQ untuk digunakan dalam manajemen persediaan rumah sakit walaupun terdapat kesulitan dan keenggaran dari rumah sakit untuk mengestimasi biaya pemesanan dan penyimpanan.Kata kunci: Economic order quantity, analisis sensitivitas, manajemen inventori rumah sakit, overstock, manajemen persediaan di bidang kesehatan, biaya pemesanan, biaya penyimpanan, fixed order quant

Abstract

Soigne Adornment is a fashion company that focuses on accessories. High market demand in the fashion industry is very dependent on the supply and productivity of companies in making products. Therefore, the operating system must be prepared carefully. As one of the companies in the fashion industry, Soigne Adornment is needed to maintain the operating system. Soigne Adornment itself has experienced several operational problems in production because it does not have the right schedule and estimated demand, resulting in losses. Losses experienced due to several aspects, namely from the excess of raw materials and delays in ordering. These problems affect the company's performance and have an impact on sales. This study aims to make an estimate of demand and find the most efficient method to minimize production costs. Therefore, using Material Requirement Planning (MRP) can overcome the problems that have occurred. In this study, what must be done first is to determine the number of forecasting requests by interviewing through the Jury of Executive Opinion method by interviewing the owner of Soigne Adornment and interviewing the owner of the Velour Jewels Company. After the estimated data is collected, researchers conduct production scheduling using the Master Production Schedule (MPS), Bill of Materials (BOM), and Lead Time. After the scheduling process is completed, an analysis is conducted to find the lowest production costs using the Lot-Sizing technique through three methods, namely Lot-For-Lot (L4L), Economic Order Quantity (EOQ), and Order Quantity Period (POQ). Based on the results of the analysis, it shows that Economic Order Quantity (EOQ) is the most efficient method for minimizing production costs. Keywords: Soigne Adornment, Fashion Company, Material Requirements Planning, Demand Forecasting, Production SchedulingSoigne Adornment is a fashion company that focuses on accessories.

Aims of this research is to implement the improvement of production lead time in one of the sportswear SME that apply ‘Made by Order’ type of production. Six sigma approach will be used on this research to improve the operational aspect in the company, which was initially comes from the 1990s in a manufacturing company for manufacturing and transactional processes. Six Sigma has proven successful in decreasing lead time or variation, bring up customer satisfaction, and make profit significantly increasing.One of the Six Sigma tools that will use on this research is DMAIC (Define, Measure, Analyse, Improve, and Control), a step-by-step to find the critical process in order to identified and remove the bottle neck, so the production lead time will be reduced with the good quality on production result. In Define step, defined the problem which occur in Panjers. Then the next step is Measure, in this step measured the losses of Panjers and calculate the lead time by explaining all the business process. After knew the losses and already knew the lead time, next step is Analysed the bottleneck and the cause of bottleneck by using fish bone diagram. Then knew the root cause of the problem and gave the solution for improve the business process and decrease lead time. To maintain the improved business process, the next step is controlling, which will use PDCA (Plan, Do, Check, and Act) tools for this step.Keywords : Six Sigma, DMAIC, Business Process, Made-by-Order, Production Lead Time
