The Journal of Marine Research and Technology (JMRT) (p-ISSN 2621-0088 | e-ISSN 2621-0096) is an open access, scientific journal that aims to publish the dynamic of the coastal and ocean, its ecosystems and coastal environment, and Observation technology. JMRT is a peer-reviewed journal publishes original articles and critical reviews of current issues in marine science and technology. The range of topics extends from research in Oceanography, marine habitats, living resources, management and conservation issues related to the marine resources. This includes remote sensing, ocean modelling, geographic information System (GIS), coastal engineering, coastal processes, marine instrument, ecology, genetics, marine pollution, fisheries, marine ecotourism, and it's economic and social. JMRT provides a forum for the discussion and sharing all the latest issues in marine research and technology. Editorial manager system is an online manuscript submission, review and tracking system. JMRT is issued twice a year, each February and August.

Abstract

Seagrass, a flowering marine plant, has adapted to thrive in shallow seas where its stems grow along the substrate. Seagrass meadows offer numerous benefits due to the mutual interaction between seagrass and marine biota. The primary objective of this study was to determine the precise composition of the epifauna community and establish the relationship between epifauna abundance and seagrass density. The research was conducted between October and December 2022. Purposive random sampling was employed as the research methodology, with three stations selected at each research location. The findings revealed the presence of nine seagrass species, namely Cymodocea rotundata, C. serrulata, Enhalus acoroides, Halodule pinifolia, H. uninervis, Halophila ovalis, H. minor, Thalassia hemprichii, and Syringodium iseotifolium. The highest species density, recorded at Prapat Agung Beach, was observed in the H. uninervis type with a density of 216 ind/m2. Conversely, at Segara Ayu Beach, the highest species density was found in the C. rotundata type, with a 320/m2 density. Segara Ayu Beach exhibited the highest epifauna diversity, scoring 3.46 in the high category. Additionally, it displayed the highest epifauna uniformity, with a score of 0.92 in the high category. Prapat Agung Beach had the highest epifauna dominance index, scoring 0.19 in the low category. The correlation analysis between seagrass density and epifauna abundance yielded a correlation coefficient (r) of 0.779, indicating a strong relationship. The ANOSIM test results indicated a significant difference in the abundance of epifauna, with an R-value of 0.9657 and a ???? value of 0.0001.
