PEMODELAN DINAMIKA MAKANAN CEPAT SAJI DAN OBESITAS UNTUK MENGEVALUASI EFEK TEKANAN TEMAN SEBAYA

Obesity is a health problem that is increasing among teenagers and consumption of fast food is often cited as a contributing factor. It could also be that peer pressure influences unhealthy eating behavior, including consumption of fast food. The aim of this research is to model the dynamics of fast food consumption and adolescent obesity to assess the impact of peer pressure. This research is basic or theoretical research. The method used in this research is descriptive (illustrative). This research was carried out by identifying variables, parameters and hypotheses related to the problem so that a mathematical model can be created for fast food and obesity to assess peer pressure. In addition, mathematical model analysis is carried out and the stability of the equilibrium point is determined. Based on the results of the analysis of the mathematical model of fast food and obesity to assess the effect of reference point pressure, the equilibrium point is reached and the stability of the equilibrium point observation is based on locally asymptotically stable and unstable Jacobian matrix values, a simulation is carried out.
