Public service is the fulfillment of the desires and needs of society by state administrators. Public service activities at RW 04 Kapuk Poglar West Jakarta include citizen data collection, monitoring, community services, and activity information. Until now, the process of public services implementation still uses records through books and paper, so that the information provided is not conveyed to all residents of RW 04. A website-based information system is required to meet these needs. The application of e-government plays a critical role in improving the quality of public services and can overcome existing problems. The purpose of this study was to design a website-based service information system and application letter "sipadu" at RW 04 Kapuk Poglar. The type of research used is qualitative research, while data collection is carried out by field studies using observational data collection techniques, interviews, and literature study. The result is a system that can simplify and speed up the process of making letters and processing community administrations.
