Adolescent Health Registration is an official application designed to be a digital bridge between adolescents and Posyandu (Integrated Health Post) cadres. We are here to help you (adolescents) monitor your nutritional and health status in real-time, while also making it easier for Posyandu cadres to manage data. This application allows cadres to register new adolescents, record health check results (such as height and weight), and automatically calculate nutritional status (Body Mass Index/BMI) based on the input data. As an adolescent, you have direct access to your latest check results and health history, ensuring you always know how to maintain optimal nutrition. As a cadre, this is a digitalization tool that makes administration faster, more accurate, and more efficient.
