<![CDATA[According to an analysis conducted by the World Bank Group, WHO, and UNICEF, around 144 million children who are under the age of five (21.3%) were affected by stunting worldwide in 2019. By 2022, this figure had risen to an estimated 148.1 million children (22.3%). This study aims to evaluate the health promotion interventions utilizing a prototype of a stunting health information system and a 3D pageflip e-module in enhancing attitudes and knowledge for the prevention of stunting in South Tangerang. This study applied a quantitative approach combined with a quasi-experimental design, utilizing a two-group design with a pretest and post-test measurements framework. A total of 106 individuals surveyed were included, divided equally into two groups: one group received the prototype stunting health information system intervention, and the other was provided with the 3D Pageflip e-module, comprising 53 participants for every group. The Wilcoxon test showed the prototype of the stunting health information system group showed a significant difference for knowledge (p = 0.046) and attitude (p = 0.025), and the 3D pageflip e-module group showed a significant difference in knowledge and attitude (p = 0.000). The Mann-Whitney test showed that there was a significant difference for knowledge (p = 0.000) and for attitude (p = 0.042). The effect size test for knowledge is 1.06 and for attitude 0.27. It can be concluded that the prototype of the stunting health information system and the 3D pageflip e-module effectively increase mothers' knowledge and attitudes regarding stunting prevention.
