The solution of the Nonlocal SNLD equation is a soliton wave in the form of a Gaussian ansatz obtained using the method of Variational Approximation (VA). The stability of the solution is also analyzed using the VA. These semi-analytical results are then compared to numerical results. The soliton and its stability obtained via VA is concluded to be having a fairly good conformity with numerical results. %U https://journal.itera.ac.id/index.php/indojam/article/view/730 %J Indonesian Journal of Applied Mathematics %0 Journal Article %R 10.35472/indojam.v2i1.730 %P 17-24%V 2 %N 1 %@ 2774-2016 %8 2022-04-15
