Development and Implementation of the “Keluarga Carade” App: Optimising Information Technology-Based Stunting Surveys to Support Public Health Efforts

Abstract

Stunting represents a persistent malnutrition issue that impedes children's physical and cognitive development, with potentially lasting impacts throughout their lives. This study aims to develop and implement the Keluarga Carade app, a real-time information technology-based stunting survey system intended to assist surveyors in collecting public health data in Jeneponto Regency. The app was constructed using the Laravel framework and MySQL for data storage, offering features such as family data management, prospective bride data management, questionnaire data input, survey result evaluation, and coordinate point visualization. The study adopted the Unified Theory of Acceptance and Use of Technology (UTAUT) model to evaluate user acceptance, focusing on four variables: Performance Expectancy (PE), Effort Expectancy (EE), Social Influence (SI), and Facilitating Conditions (FC). Data collection was carried out using a Likert-scale questionnaire with a sample of 32 public health surveyors selected through purposive sampling, and the data were subsequently analysed for validity, reliability, and correlation. The findings confirmed the validity and reliability of all variables, with strong positive correlations observed, highlighting the app’s ease of use, functionality, and effectiveness in supporting stunting survey activities. The Keluarga Carade app demonstrates the potential to optimise stunting monitoring by facilitating efficient data collection and analysis, thus supporting public health efforts to combat stunting. Future research may explore the app’s long-term impact on reducing stunting rates and its integration within broader public health frameworks.
