Development of the SPMI Model Based on Planning and Sustainability (PCQI) to Improve the Quality of Academic Services at PTS Medan City

This research aims to develop an Internal Quality Assurance System (SPMI) model based on Planning and Sustainability (PCQI) to improve the quality of academic services at Private Universities (PTS) in Medan City. This model is designed to overcome challenges in improving the quality of higher education through a systematic and sustainable approach, with an emphasis on stakeholder and alumni involvement.The research method used is development research with the 4D approach (Define, Design, Develop, Disseminate) introduced by Sivasailan Thiagarajan. The Define stage includes identifying needs and problems in implementing SPMI at PTS, including collecting data from stakeholders and alumni. The Design stage involves designing a PCQI model that integrates components of strategic planning, measurable implementation, continuous evaluation, and sustainability efforts. In the Develop stage, the PCQI model was tested in several private universities in Medan City to assess its effectiveness in improving various indicators of academic service quality, such as student satisfaction, teaching quality and graduate success. The Disseminate stage focuses on the wide application and dissemination of this model in other private universities.The research results show that the implementation of the PCQI model significantly improves the quality of academic services.
