Design Warehouse Information System to Increase Stock Accuracy

Abstract

In its development, the warehouse is currently not only used as a room for storage but has been integrated with the information system used in carrying out its warehousing activities. One of the objectives of the warehousing information system is to achieve stock accuracy according to the Company's target. PT Zoomlion Indonesia Heavy Industry (PT. ZIHI) is one of the heavy equipment industry companies engaged in the provision of heavy equipment, construction and plantations that have used the SAP system in managing their inventory but have not reached the stock accuracy target expected by the Company because in SAP there is no warehouse module. The purpose of this study is to find out what causative factors can affect stock inaccuracies in Jakarta warehouses, find out the dominant factors that cause stock inaccuracies and to find out the improvements made in increasing stock accuracy in PT Zoomlion Indonesia's Jakarta warehouse. The methods used are the DEMATEL (Decision Making Trial and Evaluation Laboratory) method, five why analysis, fishbone diagrams, for further design of the bin location system database. The results showed that (1) the factors causing stock accuracy inaccuracies at PT Zoomlion Indonesia Heavy Industry were due to increased receiving, storage, and shipping activities and limited manpower, and were not supported by a system that facilitates the location of parts. Meanwhile, according to fishbone analysis, the factor diagram that causes stock accuracy is not optimal is done through the five whys approach, which consists of human factors, methods, materials and the environment, (2) the dominant factors that cause inaccuracies in stock accuracy occur at risk (E10) There is no SAP support system for registering Bin location, (3)The web database stock location design developed is a form of improvement effort from the manual monitoring system that is not running smoothly. This stock location database will provide information about materials while in the warehouse room. Therefore, the use of a mobile- based web server can make it easier for users to access the system from a smartphone device.
