Abstract

Abstrak. Pada makalah ini dikaji persamaan Schrodinger nonlinier diskrit nonlokal
(SNLD-N) yang menginterpolasi persamaan SNLD kubik nonlokal dan persamaan SNLD
Ablowitz-Ladik nonlokal. Salah satu hal yang menarik dari persamaan ini adalah eksis-
tensi solusi soliton yang dimilikinya. Solusi soliton pada persamaan SNLD-N ditentukan
dengan menggunakan metode aproksimasi variasional (AV). Solusi AV yang diperoleh se-
lanjutnya dibandingkan dengan solusi numerik. Hasil-hasil yang diperoleh menunjukkan
bahwa solusi AV valid dan mempunyai kesesuain yang baik dengan solusi numerik.
