In this final project a rotating and charged black hole is discussed with the NUT parameter in the gravity Rastall theory (KNN-R black hole). Rastall's theory of gravity which states that the momentum-energy tensor does not have to fulfill $ \ nabla ^ {\ mu} T _ {\ mu \ nu} = 0 $. Rotational parameters and NUT parameters are raised using the Newman-Janis algorithm. From the solution of the space-time metric for the KNN-R black hole, an analysis of the movement of massive and massless particles at the equator with a circular path is analyzed. The results are the greater the rotation parameters, causing the radius of the path to be smaller because the horizon gets smaller with increasing rotation parameters. In this final assignment, the radius of the massless particle path is also obtained and always smaller than the radius of the massive particle path. In this final project the Petrov type for KNN-R black hole is also obtained, namely Petrov type I which is a general case, or called algebraically general.
