Summary:The study was conducted to explore and confirm eight Thalassia hemprichii descriptors as indicators of two latent structures and to examine invariance in inhabited and uninhabited locations. Eight seagrass meadows at Kepulauan Seribu Marine National Park (TnLKs) were purposively selected to encompass anthropogenic gradient pressure. The T. hemprichii descriptors were analyzed using exploratory factor analysis in the confirmatory factor analysis (CFA) framework (E/CFA strategy), pure CFA model based on E/CFA strategy and multiple indicators multiple causes (MIMIC) modelling or CFA with covariates to examine invariance in two groups (inhabited and uninhabited locations) using the established CFA model. The final results indicated that the measured T. hemprichii descriptors have more clearer latent structures than the derived T. hemprichii descriptors, showed large effect differences between inhabited and uninhabited locations and T. hemprichii potentially could be used as bioindicator for biomonitoring environmental quality for tropical coastal waters.
