Control Information

The system that is currently running in recording inventory at PT Berlina Tbk Tangerang is considered ineffective and efficient because it still uses paper and the process of inputting and recapping goods data is semi-computerized in Microsoft Excel. which causes problems, namely too much stock of goods so that it increases the load in the warehouse and too little stock of goods which results in an exhaustion of stock in the warehouse. To solve this problem, we need an inventory control information system. The method of analysis uses the EOQ (Economic Order Quantity) method. For the system design process using sublime as the writing language and programming PHP, and XAMPP as localhost, the database uses MySQL. This study aims to design an inventory control system in the HRD department at PT Berlina Tbk Tangerang, and to make it easier for the HRD Department to input and create inventory reports. With this research, it can produce an inventory control system design that is more effective and efficient and can find out the storage costs in the warehouse. From the calculation of the EOQ method, it is found that it is 20% smaller than the previous storage and the total cost of ordering in a year is 2x orders. Thus, it means that there is a very real difference between the inventory policies implemented by the company and the EOQ method.

Pizzahut Setiabudi Semarang is a middle class restaurant in Indonesia that serves pizza, pasta and also various kinds of food. The process of recording stock inventories at Pizzahut Setiabudi currently still uses manual recording on books, both incoming and outgoing materials. In addition, the procurement process for raw material stock only uses estimates, this can lead to excess stock in the warehouse or actually experience a stock shortage which can later hamper the operational process of the business. In this research, we build a raw material inventory control system to help restaurants manage material stock data using the Economic Order Quantity (EOQ) method. EOQ is a method used to optimize the purchase of raw materials that can reduce inventory costs so that the efficiency of material inventory in the company can run well.

The study aims to test the effectiveness of the implementation of several inventory control methods to improve the smooth operation in a trading company of industrial equipements components that have difficulty in maintaining inventory data accuracy, inventory shortages and in other hand excess unrequired inventory. The research data used is taken from the ERP report data and manual reports created by the perpetrators of the operational activities of the Inventory Control for the period 2016 - 2018. The sampling method used is purposive sampling of the product sales data in years 2016 – 2018  as much as 2498  Stock  Keeping Unit (SKU) which is then  processed using the method of ABC analysis and  FSN (Fast Moving, Slow Moving and None Moving) analysis to get  10  SKUs that belongs to the category A and  F (Fast Moving) group as a sample of research. The research method uses the Quantitative method with the use of ABC analysis, Forecasting and Economic Order Quantity. The results shows that the implementation of ABC analysis effectively reduced the workload of periodic counting and is able to improve data accuracy to be higher level. The exponential smoothing forecast method shows the least gap to the actual value and EOQ effectively optimizes ordering and holding costs and reduces the risk of failure in Inventory Control and positively affects the smoothness of the operation process.
