Waterfall Model for Design and Development Coffee Shop Website at Malang

Along with the development of technology and information, various product transaction activities can be easily carried out by utilizing the internet network. Prospective buyers can make transactions faster with potential sellers via the internet without having to visit first. A company can easily sell a product through the website. Dua Ruang is a cafe selling drinks from coffee to mocktails in Malang City, Indonesia. The implementation of transactions at the Dua Ruang cafe still uses manual transactions where prospective buyers have to come to the cafe to buy their products, with this method less than optimal in business development. Based on these problems, we designed a website that will make transactions easier and digital. We use the Waterfall method for the design and design of the Dua Ruang website. This method starts with Requirements, Design, Development, Testing, and Evaluation. The test results show the website can function properly and can be used for further implementation. The existence of a website-based sales application will be the best solution for solving problems at the Dua Ruang Cafe so that it can increase sales turnover.
