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.
