abstract: Telah dilakukan penelitian yang bertujuan mengetahui bentuk simulasi komputasi
dari pendeteksian gas NO2 pada sensor ZnO yang berbasiskan perubahan fungsi
kerja (Δφ). Hasil simulasi kemudian dibandingkan dengan hasil eksprimen
Widanarto (2011). Simulasi pada penelitian ini dijalankan menggunakan
MATLAB dengan Persamaan Differensal Biasa Orde Satu Terkopel didasarkan
pada lima persamaan reaksi yang digunakan. Dari penelitia ini, diketahui bahwa O
merupakan cakupan yang mendominasi dipermukaan ZnO, dan diperoleh hasil
bahwa nilai setiap parameter tidak saling bergantung dan mempengaruhi satu
sama lain ketika dilakukan optimasi. Simulasi ini menghasilkan grafik perubahan
fungsi kerja terhadap waktu kurang sesuai dengan hasil eksperimen yang
didapatkan Widanarto seiring dengan waktu berjalannya simulasi ini.

ABSTRACT

SIMULATION OF NO2 GAS DETECTION REACTION MECHANISM IN

ZnO MATERIAL BASED ON WORK FUNCTION

By

DIAH PURWARINI

Research has been carried out which aims to determine the form of computational
simulation of NO2 gas detection on ZnO sensors based on changes in work
function (Δφ). The simulation results were then compared with the experimental
results of Widanarto (2011). The simulations in this research were run using
MATLAB with Coupled First Order Ordinary Differential Equations based on the
five reaction equations used. From this research, it is known that O is the coverage
that dominates the surface of ZnO, and the results obtained are that the values of
each parameter are independent and influence each other when optimization is
carried out. This simulation produces a graph of changes in the work function
over time that is less in line with the experimental results obtained by Widanarto
as the simulation progresses.

Keywords: NO Gases, Work Function, ZnO Materials.
