The purpose of this study is to determine the Quality of Population Administration Services through the Plavon Dukcapil Website at the Population and Civil Registration Office of Sidoarjo Regency. The method used in this study is descriptive qualitative. This research will focus on service quality indicators located in 5 dimensions said by Parasuraman, Zeithaml, &; Berry (in Hardiyansyah, 2011: 11), namely; Tangibles, Reliability, Responsiveness, Assurance, and Emphaty. Data collection techniques used in this study are interviews with informants, direct observation in the field, and documentation.
