<![CDATA[Objective: This study aims to analyze the effectiveness of the implementation of the Population Administration Information System (SIAK) in population administration services in Krembung District, Sidoarjo Regency. Method: The method used is descriptive qualitative with data collection techniques through observation, interviews, and documentation. Effectiveness is measured using five indicators according to Campbell J. P., namely program success, target success, satisfaction with the program, input and output levels, and overall goal achievement. Result: The results of the study show that the implementation of SIAK has facilitated data management and accelerated services, but still faces several obstacles, such as disruptions to the main server, the lack of skills of some officers who are elderly, and the limited availability of blank documents. Although the infrastructure is sufficiently supportive, human resource readiness still needs to be improved through ongoing technical training. Novelty: Therefore, it can be concluded that SIAK is quite effective, but to achieve optimal effectiveness, strengthening is needed in terms of technical aspects and human resource management so that population administration services can run optimally and sustainably.]]>
