Psikologi Mepet Sawah (PsiMeWah) is a student activity unit of the Faculty of Psychology, Diponegoro University, which focuses on comedy theater arts. As a platform for developing student potential, PsiMeWah creates alternative activities that allow its members to channel their interests, talents, and potential. The primary goal of PsiMeWah is to harness and optimize the potential of psychology students at Diponegoro University, enabling them to become not only academically outstanding but also creative, expressive, and professional.

Every year, PsiMeWah produces a theater performance commonly referred to as Pentas Produksi, which serves as a platform for showcasing the outcomes of talent development and training. PsiMeWah is also frequently invited to collaborate or perform with various institutions, both within and outside the university.

However, its regular collaborative program is the Tetralogy, which involves collaboration with three other student activity units in the form of a musical drama theater production. PsiMeWah continues to provide training for its members and to develop its human resources so that they are able to compete in theater competitions, monologue performances, character makeup contests, and stand-up comedy events.
