This research aimed to study interaction of <em>Thalassia hemprichii</em> measured and derived variables (metrics), at two locations i.e., inhabited island (high anthropogenic location) and uninhabited island (low anthropogenic location). Confirmative approach was conducted using a developed conceptual model based on preliminary studies, the conceptual model was analyzed in multivariate context using data from field observation. The result showed that <em>Thalassia hemprichii</em> dominated and have higher above ground biomass value in inhabited area which indicated high nutrient input, meanwhile uninhabited area showed a higher below ground biomass value. Above ground of <em>Thalassia hemprichii</em> that have direct effect on its biomass and below ground metrics was leaf width, meanwhile leaf length of <em>Thalassia hemprichii </em>have indirect effect on its biomass and below ground metrics. The result also indicated some different metric covariations which were influenced by the degree of <em>Thalassia hemprichii</em> density. Leaf length, leaf width, density, and percent cover of <em>Thalassia hemprichii</em> potentially could be used as components in multimetric index and bioindicator for environmental quality.</p> <p>&nbsp;</p> <p>Keywords: anthropogenic disturbance, path analysis, structural equation modeling, <em>Thalassia hemprichii</em></p&gt;}, number={3}, journal={Jurnal Ilmu Pertanian Indonesia}, author={Zulfikar, Andi and BoerMennofatria and AdriantoLuky and PuspasariReny}, year={2020}, month={Jul.}, pages={356-364} }
