      Abstract
      Solusi metrik Kerr-Newman merupakan solusi paling umum untuk black hole. Konstruksi metrik pada dimensi 4+1 didasarkan pada asumsi bahwa hukum-hukum fisika berlaku di semua dimensi. Tujuan penelitian ini adalah untuk mengonstruksi solusi metrik Kerr-Newman 4+1 dimensi beserta tensor medan elektromagnetiknya. Dilakukan pengambilan tebakan, reverse engineering, analisis persamaan medan Einstein, manipulasi aljabar, dan pengambilan limitasi untuk mengonstruksi dan membuktikan solusi metrik dan tensor medan elektromagnetik. Terdapat komponen-komponen off-diagonal pada tensor metrik yang diperoleh. Hal ini berkaitan dengan keberadaan parameter momentum angular a. Keberadaan parameter muatan Q dan parameter momentum angular a pada black hole Kerr-Newman mengindikasikan keberadaan parameter magnetik yang muncul pada black hole Kerr-Newman. Keberadaan parameter magnetik berkontribusi dalam membentuk medan potensial yang diajukan, dimana medan potensial tersebut terbukti benar dengan menganalisis komponen-komponen tensor medan elektromagnetik yang diperoleh.
       
      Kerr-Newman metric solution is the most common solution of black hole. Metric construction on 4+1 dimensions based on the assumption that physics law valid in all dimension. The aims of this research is to construct Kerr-Newman metric solution in 4+1 dimension and it’s electromagnetic field tensor. Guesswork, reverse engineering, analysis of Einstein’s field equation, algebraic manipulation, and limitation taking are carried out to construct and prove metric solution and electromagnetic field tensor. There is off-diagonal components in metric tensor obtained. It is related to the existence of angular momentum parameter a. The existence of charge parameter Q and angular momentum parameter a in Kerr-Newman black hole indicates the existence of magnetic parameter which appear in Kerr-Newman black hole. Magnetic parameter existence is contribute in the forming of potential field which submitted, whereby this potential field is proven correct by analyzing electromagnetic field tensor components obtained.
