Analysis of Factors Affecting the Acceptance of Maternal and Child Health Monitoring (Stunting) Applications in Suburban Areas Using a Modified Technology Acceptance Model (TAM): A Case Study in Sukabumi Regency

Maternal and child health, particularly in suburban areas with limited access to healthcare services, is a critical public health issue. One of the significant challenges is stunting, where Indonesia has a prevalence rate of 30.8%, higher than Thailand (10.5%) and Malaysia (20.7%). In Sukabumi Regency, the stunting prevalence reaches 27.5%, indicating ongoing challenges in addressing maternal and child health. This study analyses the factors influencing the adoption of maternal and child health monitoring applications by homemakers in suburban areas as part of stunting prevention efforts. The method used is a modified Technology Acceptance Model (TAM), which evaluates Perceived Usefulness, Perceived Ease of Use, Content and System Quality, and User Experience. Data were collected through a questionnaire given to 262 respondents at Posyandu, using a 4-point Likert scale, and analysed with Structural Equation Modeling (SEM) using the Partial Least Square (PLS) technique. The research results show that content, system quality, and user experience significantly affect perceived usefulness and ease of use.Additionally, these factors positively influence behavioural intention to use the health monitoring application. The model demonstrates predictive solid power, with R<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> values of 0.715 for Behavioral Intention, 0.758 for Perceived Usefulness, and 0.797 for Attitude Toward Using. The study concludes that improving system and content quality and user experience is essential to increasing the adoption of maternal and child health applications to support stunting reduction programs in suburban areas.
