Comma is optional. Comma is used in written language to indicate a pause in spoken language. There are other pose indicators such as semicolon and colon etc. In your two example sentences, even without the comma meaning is not lost. Commas become necessary in longwinding sentences with very long clauses, otherwise the reader loses track of the information conveyed in the sentences.
Your example sentences are fine without the commas.
