Islamic University Spatial Network: Integrating Kinetic Fields and Spatial Nodes between the Campus and Urban Pesantren in Semarang, Indonesia

The expansion of State Islamic Universities (PTKIN) in Indonesian urban areas has reshaped spatial relations among campuses, residential neighborhoods, and surrounding Islamic boarding schools (pesantren). However, studies integrating Islamic campuses and pesantren within a socio-spatial network framework remain limited. This study examines the socio-spatial network connecting UIN Walisongo Campus and nearby pesantren, with the campus as the primary node, Jl. Prof. Hamka as the main corridor, and pesantren as religious nodes embedded in the urban fabric. This qualitative case study used field observation, morphological mapping, Doxiadis' kinetic field framework, and in-depth interviews with academic Kiai, religious Kiai, santri-students, residents, and university stakeholders. The findings show that Jl. Prof. Hamka links the campus to housing clusters, mosques, and open spaces through a branching road hierarchy. An approximately 830 m reference helps describe relative walking-field accessibility. Locations beyond it are discussed in relation to a motorized field. Non-physical connections are reflected in daily mobility, the practice of studying at university while living in a pesantren, and socio-religious interactions among Kiai, santri-students, academics, and residents. This study contributes to an understanding of urban Islamic campus networks by showing how physical proximity, mobility, everyday practices, and socio-religious interactions shape campus-pesantren-neighborhood relations. The tradition of combining university study with pesantren life is central to these relations. Thus, PTKIN expansion involves not only physical growth but also academic, spiritual, and social connections within the urban residential context.
