Current technology has helped users in doing various things and activities that are able to produce the latest and innovative technology in various fields. Many people get convenience to meet their information and communication needs with the internet. The background of the creation of the Outdoor Equipment Rental Information System at Vexa Adventure Based on the Web is the processing of data that is still manual (reporting is done by bookkeeping every month) values that can be at high risk of damage and loss. The purpose of this study is to be able to design and build an outdoor equipment rental Information System at Vexa Adventure based on the web, using PHP - MySQL. And to find out the impact of implementing the system. The type of research used is engineering research with a research method using the Waterfall method. The stages of the waterfall method are Communication, Planning, Modelling, Construction, Deployment. The design used in this study is DFD (Data Flow Diagram) modelling which consists of four main components, namely data input, data output, data storage, and processes. The Flow of Document (FOD) is used to describe the ongoing procedure. The results of this study are in the form of a Web-Based Outdoor Equipment Rental Information System. The impact of implementing this system is proven by user evaluations using Likert scale calculations which show a value of 80%, which means the impact of implementing this system can help Vexa Adventure admins and owners in carrying out rental transactions.
