Abstract

Health is a basic need in human life. People spend a lot of money to maintain their health. One of the preventive health service options is to vaccinate. Indonesia is a country that can produce its own vaccines with its local pharmaceutical companies. The company faces stiff competition in today's rapidly growing market. Therefore, evaluation and assessment are needed to measure the progress of the company's development. One useful assessment is a company's financial review. Inventory control ensures that the planned approach can minimize costs without disrupting the production process. This research simulates data of demand and analyzes the inventory control based on simulated data. The object used in this research is the inventory of products of pharmaceutical companies. The data used is secondary data such as data of product quantity sold per period, purchasing cost, order cost, holding cost, shortage cost, and lead time. The method used for inventory control is Economic Order Quantity (EOQ) model and Monte Carlo simulation. The simulation results on the monthly demand for vaccine products show that the total demand for one year is 3.394.805 vials for Vaccine A, 1.320.900 vials for Vaccine B and 107.345 for Vaccine C. Based on simulated data processing, calculations using the probabilistic EOQ model result in total inventory costs of Rp.456.918.008.386,14 for Vaccine A, Rp 218.292.795.949,34 for Vaccine B, and Rp. 9.177.930.319,05 for Vaccine C.

Abstract

PT. Ekadharma International Tbk. is a company that expands its business into the adhesive tape industry in meeting the needs of the Indonesian market. The development of this company must also be balanced with its financial stability. The source of information used to measure the company's financial condition is financial statements. The benchmark used in this research is vertical analysis and solvency ratio analysis which shows the company's ability to pay its obligations when the company is liquidated. The types of ratios used are Debt to Asset Ratio and Debt to Equity Ratio. Vertical analysis shows that the total assets of PT. Ekadharma International Tbk. always increase from year to year. While the results of the calculation of the solvency ratio show that the percentage is in a relatively small number, namely 10%-20% and always decreases every year. By presenting data that has been processed and interpreted, this balance sheet report can provide good insight for the company, employees, and shareholders in making economic decisions for the company.
