This research aimed to 1) develop an intelligent chatbot for communication and citizen assistance for Local administrative organizations, 2) evaluate the system’s performance, and 3) examine user satisfaction. The sample in this study consisted of 50 participants, comprising 20 personnel and 30 members of the population within the service area, selected through purposive sampling. The research instruments comprised: 1) The interview was designed as an open-ended questionnaire to explore issues related to the processes and procedures involved in citizens’ applications for assistance; 2) a chatbot system developed based on the System Development Life Cycle (SDLC) using PHP, HTML, and JavaScript, with a MySQL database deployed on Linux CentOS and Apache web server, integrated with LINE Application, LINE Developer Account, and Webhook technologies; 3) a system performance evaluation form assessed by five information technology experts using the black-box testing technique; and 4) a user satisfaction questionnaire employing a Likert rating scale. Data were analyzed using mean and standard deviation.
       The research findings indicate that the developed chatbot system is capable of supporting assistance requests, providing consultation services, and disseminating organizational information effectively. This suggests that local administrative organizations can adopt and implement chatbot systems to enhance the efficiency of public service delivery in a digital context. The overall system performance evaluation was rated at a high level (= 4.44, S.D. = 0.49), and the satisfaction of users who were personnel was at a high level (= 4.45, S.D. = 0.49), while the satisfaction of users who were members of the population within the service area was also at a high level (= 4.41, S.D. = 0.49).
