One-loop amplitudes of gluons in supersymmetric Yang-Mills are four-dimensional cut-constructible. This means that they can be determined from their unitarity cuts. We present a new systematic procedure to explicitly carry out any finite unitarity cut integral. The procedure naturally separates the contributions from bubble, triangle and box scalar integrals. This technique allows the systematic calculation of $\mathcal{N}=1$ amplitudes of gluons. As an application we compute all next-to-MHV six-gluon amplitudes in $\mathcal{N}=1$ super-Yang-Mills.
