Disordered system material such as organic semiconductor is widely used in devices such as transistors, which are highly utilized in the modern age techonology. As such, studies on charge transport mechanism in disordered system become quite important to explore. A combination of experimental researches complemented with theoretical and numerical studies is needed to better characterize the intrinsic nature of the charge carrier transport. Percolation model itself is a simulation which study the transport of an object through a complex porous system. In the last few decades, there had been quite a few studies from the point of view of its mathematics bases in pursuit of constructing a theory which can reproduce natural physical transport phenomena consistently. Event though there is yet to be an exact analytical solution for percolation model, the existing applications of the mathematical model of percolation have managed to produce quite accurate results in simulating some of the natural physical transport phenomena. In this thesis, the author constructed a program for percolation model utilizing The Newman-Ziff Algorithm. Which to date, is the fastest percolation algorithm and the most widely used in various studies and researches. From this program, the author hopes to study how the charge transport phenomena will be manifested when modelled using the program the author constructed using the percolation model.
