Effectiveness of Android-Based Application (Nosting) for Early Detection of Stunting and Growth and Development Screening in Children Aged 12-24 Months

/in /by

In general, data from height and weight measurements are manually entered into a growth chart, where this process takes time and can result in stunting cases being missed during the data entry process. Therefore, an early detection system was developed by utilizing the sophistication of Android which is currently widely used by the community. The purpose of this research is to build an innovative application for early detection of stunting and growth and development screening in children aged 12-24 months so that it can make it easier to monitor their growth and development based on Z-Score and KPSP. This research method is R&D. The research model used is ADDIE. This study used 43 respondents and 3 expert respondents. The sampling technique used purposive sampling. The results of the study based on the assessment of 3 experts get a value of 79.67% with a category worth using and based on a small scale trial on 43 respondents on the assessment of the effectiveness of the application getting a value of 89% so that it can be categorized as very effective. It can be concluded that the application of early detection of stunting and growth and development screening is feasible and very effective to use.

This study aims to produce a decent Android-based interactive physics learning media, to know the user’s response to the learning media and to measure the effectiveness of the learning media. This type of research is development research using a 4-D model with 34 students as research subjects. The instruments used in this study were due diligence questionnaires by experts and physics teachers, student response questionnaires and tests. Based on the results of data analysis, the material expert validation was 96% with very feasible criteria, media expert validation was 96% with very feasible criteria and the physics teacher’s assessment was 80% with feasible criteria. Student responses to small group tests with 10 respondents obtained effective (2.8), productive (3), safe (2.9) and satisfied (3) results. Whereas in the large group test with 34 respondents the results were effective (3.12), productive (3.25), safe (3.01) and satisfied (3.17). Based on the calculation of the gain value, learning media is included in the medium category in the effectiveness of increasing students’ conceptual understanding with a value of 0.6.
