Abstract:
This paper aims to process daily food consumption based on the Guideline to Healthy Food or the principle of Healthy 4
Perfect 5 (H4P5). The Guideline to Healthy Food does not include the portion and size of daily food consumption, therefore it is
perfected into the Guidelines to Balanced Nutrition (GBN). GBN is performed by consuming three servings of protein vegetables,
three servings of animal protein, eight servings of carbohydrates, five servings of vegetables, five servings of fruits, and eight servings
of water. Each part of the portion has a proportional size and dose based on GBN. The portions are measured by food composition
using the optimization process using a Genetic Algorithm (GA). Optimization by using Genetic Algorithm yielded three outputs,
namely, first, the initial objective function (0) compared to the generative objective function (1) produces a value of 6.13: 4.72 (there
is an increase in chromosomes, because, the smaller the value, the better the chromosome is). Second, probability mutation is 50% of
mutation rate, crossover probability is 5%, the maximum generation is 36, the maximum fitness point is 0.240806, and the size of the
population is 6. Third, optimization using the Genetic Algorithm in food composition produces one model solution food, one
consumption model, and two composition models. Thus, the result of this research can be a recommendation for food consumption
patterns and a reference for national food consumption policies.
