Abstract
Nutrition is very much needed in the growth of toddlers. It is very important to give babies a balanced nutritional intake at the right stage so that the baby grows healthy and is accustomed to a healthy lifestyle in the future. Children under five years of age are a group that is vulnerable to health and nutrition problems. In determining the nutritional status, it can be done in a system manner using the C4.5 decision tree classification method and entering several variables or attributes. The dataset tested was 853 toddlers. Classification is carried out to determine the nutritional status based on the weight/age (BB/U), height/age (TB/U) and weight/height (BB/TB) categories. The attributes used for the classification of BB/U are gender, weight and age. The attributes used for TB/U are gender, body length or height, and age. The attributes used for BB/TB are gender, weight, body length or height, and age. The average accuracy of the BB/U category is 90.16%, the average accuracy of the TB/U category is 76.64%, and the average accuracy of the BB/TB category is 83.83%.
Highlights
Nutrients are organic substances required for normal functioning of the body’s systems, growth and health maintenance
The test results for the BB/U category showed when the number of 3 folds the measured accuracy was 89.52%, when the Volume 3, Issue 1, pages 131–142 p-ISSN 2655-8564, e-ISSN 2685-9432 number of 5 folds the measured accuracy was 90.93%, when the number of 7 folds the measured accuracy was 90.10% and when the number was 9 folds measured accuracy was 90.10%
Based on the results of the nutritional classification of children under five using the C4.5 decision tree method, the following conclusions can be drawn: 1. The C4.5 decision tree classification method can be used to classify the nutrition of toddlers quite well
Summary
Nutrients are organic substances required for normal functioning of the body’s systems, growth and health maintenance. Children under five years of age are a group that is vulnerable to health and nutrition problems, so that the toddler years are an important period of growth and need serious attention [1]. Based on the results of the 2018 Ministry of Health's Basic Health Research, 17.7% of infants under 5 years of age (toddlers) still experience nutritional problems. This figure consisted of Under-fives who suffered from malnutrition by 3.9% and those suffering from malnutrition by 13.8% [2]. The nutritional status of toddlers can be measured anthropometry, anthropometric indices are often used, namely: body weight for age (BB/U), height for age (TB/U), body weight for height (BB/TB). The reference standard used for determining nutritional status by anthropometry is based on the Decree of the Minister of Health No 920/Menkes/SK/VIII/2002, to use the reference book of the “World Health Organization-National Center for Health Statistics” (WHO-NCHS) by looking at the Z-score
