Scientific journals have a vital role, from developing and disseminating science and technology to becoming a source of income generating for universities. Semarang State University has 166 journals, both National and Scientific Journals, spread across all faculties, study programs, institutions, and postgraduate programs. Many journals demand a good governance system characterized by a comprehensive service system. These procedures ensure consistent implementation and clear division of roles, so that journal management is carried out consistently, accountable, transparently, and professionally. This study aims to compile the main indicators of core services that must exist in journal management units at universities to support improving the performance of university journals that are consistent, accountable, transparent, professional, and able to capture future business opportunities. This type of research uses Participatory Action Research. The sampling technique is purposive sampling, and qualitative data is analyzed using content analysis. The study results found that the management of professional journals that have an orientation to business development at the university level requires a minimum of 10 key roles with 12 minimum service systems that must be developed. From these results, the next step is to develop an adequate information system outside of OJS to improve the performance of managers and services.
