Consequently, it is essential to assess the nutritional status of toddlers to ascertain their health level. This study seeks to ascertain the nutritional health of toddlers utilizing the support vector machine (SVM) methodology, taking into account body weight (BB), height (TB), age, BB/TB ratio, Z-scores for BB/U, Z-scores for TB/U, and Z-scores for BB/TB. The data of 1458 toddlers were evaluated using the knowledge data discovery methodology. This study effectively categorized toddler nutrition into six classifications including malnutrition, undernutrition, adequate nutrition, overnutrition, risk of overnutrition, and obesity. Utilizing the confusion matrix methodology with an 80% training data to 20% test data ratio yields an accuracy of 89.04%. The SVM method is effectively utilized to ascertain the nutritional condition of toddlers, hence enhancing their growth and development.</p>2025-02-12T00:00:00+07:00Copyright (c) 2025 Science, Technology and Communication Journalhttps://sintechcomjournal.com/index.php/stc/article/view/272Plasma argon particle interactions in a non-equilibrium state through the Maxwell-Boltzmann kinetic equation2024-12-12T14:41:25+07:00Azza Ronaldsaktioto@lecturer.unri.ac.idSaktioto Saktiotosaktioto@lecturer.unri.ac.idKusherbayeva Maikulsaktioto@lecturer.unri.ac.idKushkimbayeva Bibarasaktioto@lecturer.unri.ac.idMohd Rendy Samudrasaktioto@lecturer.unri.ac.idDedi Irawansaktioto@lecturer.unri.ac.idHewa Yaseen Abdullahsaktioto@lecturer.unri.ac.id<p>Non-thermal Argon plasmas serve multiple functions, particularly in healthcare and industrial applications. Numerous particles of the same species exhibit varying velocities, referred to as a 'population'. The distribution function is a standard method for characterizing a population. The speed and energy distribution functions in the Maxwell-Boltzmann equation are simulated utilizing MATLAB. The density of each species was numerically calculated using the Runge-Kutta method. This research reviews various Argon species, including Ar*, Ar<sup>+</sup>, Ar(1s5), Ar(1s4), Ar(1s3), Ar(1s2), Ar, and electrons. The parameters utilized include a pressure of 10 mTorr, an Argon temperature about 400 K, and an electron temperature about 30,000 K. The maximum velocity probability density value is observed in the Ar<sup>+</sup> species at 6.18 x 10<sup>7</sup> (m/s)<sup>-1</sup>, while the minimum value is found in electrons at 1.93 (m/s)<sup>-1</sup>. The maximum energy probability density value is observed in the Ar<sup>+</sup> species at 2.13 x 10<sup>29</sup> (Joule)<sup>-1</sup>, while the minimum value is found in the Ar(1s3) species at 1.40 x 10<sup>25</sup> (Joule)<sup>-1</sup>. The time evolution of the distribution function, independent of the coordinates <em>r</em>, is associated with <em>v</em>, at t = 10<sup>-8</sup> s. The velocity distribution function is significantly affected by the density value, while the distribution function is contingent upon the velocity.</p>2025-02-02T00:00:00+07:00Copyright (c) 2024 Science, Technology and Communication Journal
