The era of the industrial revolution 4.0 or the fourth world industrial revolution has gone by over time, where technology has become the basis of human life. Everything becomes limitless and unlimited due to the development of digital technology. This era affects many aspects of life in the fields of economy, politics, culture, education and industry. Industry is one of the places where technology is useful to help run the industry in the company. PT Indonesia Epson Industry, which is located in the East Jakarta Industrial Park (EJIP) Cikarang Bekasi area, is a company that produces various kinds of electronic goods. Production is the most important thing in the process of making products from the beginning to the end of the product process, the calculation of production results is very important to know the productivity results from the process to the finish good. PT Indonesia Epson Industry in calculating production results still applies a manual system in calculations by adding employee work, namely with production operators doing product packing while counting goods and recording the results of the production of goods and it takes time for the production admin to know real time production results. the author in this case makes a system that aims to display the number of products produced directly to the admin section using Arduino, ultrasonic sensors, Ethernet Shield and programmed using the PHP programming language then using a MySQL database connected to XAMPP in order to make system applications which is useful for displaying the number of items directly without having to wait long. The author also uses the prototyping method to make the system that is made according to what is needed by the company and what is planned. it is hoped that with this system there will be no more errors in calculations and work will be more efficient and easy and this system is expected to be used in the long term.
