We give two methods for a construction of self-orthogonal linear codes from equitable partitions of distance-regular graphs. By applying these methods, we construct self-orthogonal codes from equitable partitions of the graph of unitals in \begin{document}$ PG(2,4) $\end{document} and the only known strongly regular graph with parameters \begin{document}$ (216,40,4,8) $\end{document} . Some of the codes obtained are optimal.
