Design and Development of an Information System to Improve Services at Posyandu Dharma Wanita Rawajaya, Palembang

Posyandu is a community-based maternal and child health service in Indonesia, yet most Posyandu still depend on paper record books that are prone to recording errors, while information on schedules and services reaches parents only through conventional channels. Existing Posyandu information systems are mostly single-platform and do not give parents a view of the data that cadres enter. This study designs and builds an integrated Posyandu Information System for Posyandu Dharma Wanita Rawajaya, Palembang, in which a PHP/MySQL website for cadres and the community and an Android application share one centralized MySQL database through HTTP endpoints that exchange JSON, so that a record or schedule saved by a cadre is available to parents on their next request without re-entry. The system was developed by custom programming after observation and interviews. It covers toddler, pregnant-mother, immunization, and activity management, online activity registration with a unique registration number and a printable proof, and a date-filtered reporting dashboard. Black Box Testing of 26 scenarios in 14 feature groups, run on a pilot dataset of 21 community members, 18 toddlers, 12 pregnant mothers, 33 immunization records, and 12 activities, produced a 100% pass rate (26/26). The results indicate that a shared-database, multi-client architecture is a feasible way to digitalize Posyandu services. Standardized usability measurement, automated growth monitoring, and reminders are the next steps.
