Penggunaan Pemodelan Sumber Plasma Helium Pada Keadaan Setimbang Untuk Aplikasi Plak Gigi

---

Helium plasma source modeling was performed in order to obtain species density
at balanced conditions under pressure of 1 atm. The software used in this
modeling is matrix laboratory software (MATLAB). The equation used is a
continuity equation that depends on the position and parameters of Arrhenius.
Plasma temperatures used were 0.1 eV, 0.2 eV, 0.3 eV, and 0.5 eV. Species
involved in plasma consist of electrons, He, He+, He2
+, He* and He2
*. The
modeling results showed that the density value of He species increases as
temperature increases. It is noted that the obtained the density of He (nHe) when
reaching a balanced condition at the temperature of T = 0.1 eV, 0.2eV, 0.3 eV
and 0.5 eV are 3.0137 × 1025 m-3, 7.9506× 1026 m-3, nHe = 1.6489× 1028 m-3, and
7.1384× 1029 m-3, respectively. This is because He is a noble gas that is
monatomic and chemically inert. Thus resulting in stable plasma production and
gaining an increase in density value. Plasma-charged species are the main media
that cause disinfection of microorganisms because they can break the hydrogen
bond of the organic molecules that make up the dental plaque. So the influence of
charged species when applied to dental plaque has a more effect than that of
neutral reactive species.
