The Rumbai District official website, which has been in use since 2021, still has problems with the confirmation waiting time which is quite long and the community still has to come back to check the required files. The Rumbai District official website is also still static, because there is no interactive menu facility as a form of service to the community. For this reason, it is necessary to measure the success of the Rumbai sub-district official website in terms of system quality, information quality, service quality, use, user satisfaction and benefits and find out what influences the success of the Rumbai sub-district website through the Delone and Mclean models.
