In the first order formalism of gravity theories, there are some theories
which are not Lorentz-diffeomorphism covariant. In the framework of such
theories we cannot apply the method of conserved charge calculation used in
Lorentz-diffeomorphism covariant theories. In this paper we firstly introduce
the total variation of a quantity due to an infinitesimal
Lorentz-diffeomorphism transformation. Secondly, in order to obtain the
conserved charges of Lorentz-diffeomorphism non-covariant theories, we extend
the Tachikawa method \cite{3}. This extension includes not only Lorentz gauge
transformation but also the diffeomorphism. We apply this method to the
Chern-Simons-like theories of gravity (CSLTG) and obtain a general formula for
the entropy of black holes in those theories. Finally, some examples on CSLTG
are provided and the entropy of the BTZ black hole is calculated in the context
of the examples.Comment: 13 pages, we have improved language of the pape
