Ethnophysics arises from the desire to uncover the physics underlying various customs and local wisdoms that have been practiced for generations by certain communities. Additionally, physics concepts and mathematics can be used to shed light on the dynamics of these local wisdoms. In this study, the phenomena of ritual shifts in Ngino Village were analysed via the lattice gas model in two dimensions (2D) by generating network mappings. The rituals in Ngino Village consisted of Mubeng Ringin, Nenepi, and Merti Desa. This theoretical study was conducted by establishing a correspondence between two mathematical models, namely the asymmetric simple exclusion process (ASEP) and the static equilibrium hard-core model. A second correspondence was established between the latter model and the Ngino Village rituals. The results of this correspondence showed network mapping density profiles of the ritual shifts of people in various age groups as particles caused by new activities in Ngino Village as external potentials. The Mubeng Ringin, Nenepi, and Merti Desa rituals demonstrated shifts in the network mapping density profiles caused by attractive potentials of career/occupation, religious and educational, and leisure and trade activities, respectively. The results of this study are valuable as considerations for the study and evaluation of government policies in efforts to preserve local cultures. © The Author(s), under exclusive licence to Società Italiana di Fisica and Springer-Verlag GmbH Germany, part of Springer Nature 2026.
