This study explores the implementation of the Internal Quality Assurance System (SPMI) in the academic field at Universitas Muhammadiyah Metro, Lampung, through the PPEPP cycle: determination, implementation, evaluation, control, and improvement. Using a qualitative approach with a naturalistic phenomenological perspective, data were collected through interviews, observations, and document analysis over six months. The findings indicate that UM Metro has developed a systematic quality assurance mechanism supported by validated instruments, online internal audits, structured quality teams, and continuous improvement practices. The Quality Assurance Institute (LPM) plays a central role in coordinating quality control across university units, faculties, and study programs. The implementation of SPMI refers to the National Higher Education Standards (SNPT) and Al-Islam and Kemuhammadiyahan (AIK) standards, reflecting the institution’s commitment to sustainable academic quality development.
