One way to punctuate a compound sentence correctly is to join the two dependant clauses with a semicolon.

Explanation:

A semicolon is commonly used during writing in the English language. A semicolon can be used to punctuate the compound sentences. Also, a comma can be used if a corresponding word such as and or but is used. A semicolon is more pronounced in the sentence than a comma.

One example of a semicolon in a sentence is "I have to go to work tomorrow; I can't go to the party tonight." This sentence can be made into two sentences by using a period instead of a semicolon.
