Abstract

Metrik FLRW adalah sebuah metrik ruang-waktu yang digunakan untuk memodelkan alam semesta. Dalam membangun metrik ini, digunakan asumsi prinsip kosmologi, yaitu alam semesta isotropik dan homogen.
Setelah itu, metrik FLRW dikerjakan pada Persamaan Medan Einstein dengan Konstanta Kosmologi, sehingga didapatkan dua solusi Friedmann.
Solusi tersebut adalah solusi Friedmann jenis pertama dan solusi Friedmann jenis kedua. Pada tugas akhir ini, digunakan solusi Friedmann jenis
pertama yang telah dimodifikasi agar sesuai dengan keadaan fisis alam
semesta untuk memodelkan alam semesta. Dari model ini, dibandingkan antara model yang memiliki konstanta kosmologi dan tidak sehingga
didapatkan pengaruh konstanta kosmologi terhadap model standar alam
semesta.
====================================================================================================
Friedmann - Lemaitre - Robertson - Walker metric is a space-time metric
using to make a model of the universe. Cosmological principles, isotropic and homogeneous universe, is used to build this metric. After that,
the FLRW metric applied to Einstein Field Equation with Cosmological
Constant and consist two solutions. These solutions are first Friedmann
equation and second Friedmann equation. In this final project, first Friedmann equation with some modifications are chosen to so it would fit
the physical properties of the universe. From this model, universe with
cosmological constant can be compared to universe without cosmological
constant. In this work, we investigate the influence of cosmological constant to the standard model of the universe.
