The operational system is an important thing that needs an organization in large scale industries to small scale like a restaurant. It can lead to positive things such as good service quality, standardized food quality, a well-recorded flow of food purchases, and other aspects, leading to a high profitability level. In the culinary industry, such as restaurants, enhancing the operational system’s quality in industrial 4.0 is always accompanied by a computer-based system. There have been many studies on computer-based operational procedures in the culinary industry. Still, most of these studies only focus on one and two areas, such as food supply, dining room service, or table ordering, so that it is not well integrated. The study we conducted combines the dining room’s service process, making food in the kitchen, and the cashier’s payment process becomes an integrated system and is interconnected seamless. An integrated approach will facilitate the restaurant in communication, accurate data management, and speed in the service process. All processes are computerized and integrated to speed up the current job. The customer assessment can be seen in a service rating when making payments, which shows that their satisfaction in restaurant operating standards is close to 90% of customers. Systematically, a test is also carried out, which states that the system being built can synchronize data between the processes carried out and make the process well organized and fast. Finally, our study also suggests that further studies should be carried out by developing this system to be used in multi-branch restaurants and using cloud-based technology to reach restaurants with minimal funds to invest in information technology.
