The lack of knowledge, attitude, and behavior towards nutrition is the main cause of KEK (chronic energy deficiency) in pregnant women. The purpose of this study was to design an android-based application based on a needs analysis to improve nutritional knowledge and attitudes of pregnant women about KEK. The research method was qualitative research, while the design used a combined method between Research and Development (R&D) and Pre-Experiment methods with one group pre-test and post-test designs. The results of the data analysis showed that the knowledge, attitudes, and behavior of pregnant women increased by 72%, 78%, and 39%, respectively. The p-value of the McNemar test results for the variables of knowledge, attitude, and behavior was 0.000 <α (0.05), indicating there were differences in the knowledge, attitude, and behavior of pregnant women before and after using the application (p <α). It was concluded that nutrition education with Android-based application media influenced the knowledge, attitudes, and behavior of pregnant women, that is, to increase the knowledge, attitudes, and behavior of pregnant women about KEK in Meo – Meo Public Health center, Baubau City. Keywords---attitudes, behavior, knowledge, nutrition, pregnant women. Introduction Chronic Energy Shortage (KEK) is one of the health problems in the world, especially in developing countries. Chronic Energy Deficiency occurs when the intake of energy, protein, or even both is not sufficient for the body's needs. Chronic Energy Deficiency affects many women of childbearing age (WUS) aged 15-45 years. Chronic energy deficiency can also affect pregnant women who have risk factors for KEK (Farida et al., 2020).
