Abstract
Prime submodule is the abstraction to module theory of prime ideal in ring theory. A proper submodule N of an R-module M is called prime submodule if for all r in R and m in M such that rm in N implies r in (N:M) or m in N. Prime submodule also generalized into weakly prime submodule and almost prime submodule. This study deal with particular cases of both of them in Z-module M_2x2(Z_9), the three submodules are equivalent in case of non-zero submodule.

Summary
Pada ‐modul ( ), submodul prima dapat dikarakterisasi sesuai teorema berikut. . Submodul adalah submodul prima dari ( ) jika dan hanya jika submodul berbentuk. Akibatnya untuk semua , sehingga diperoleh atau untuk semua. Definisi ini submodul prima kemudian diperlemah Hadi yang kemudian dinamakan submodul prima lemah. Submodul prima lemah didefinisikan oleh Hadi sebagai berikut. Dari definisi jelas submodul nol pasti merupakan submodul prima lemah. Berdasarkan definisi juga, submodul prima pasti merupakan submodul prima lemah, tapi tidak sebaliknya. {(̅̅ ̅̅)} adalah contoh submodul prima lemah, tapi bukan submodul prima. Hal ini (̅̅ ̅̅) (̅̅ ̅̅) tidak berakibat atau (̅̅ ̅̅) {(̅̅ ̅̅)}
