Abstract

The limited data and information on seagrass ecosystems in Negeri Oma provided the basis for this study. The lack of previous studies offers an opportunity to examine the ecological potential of seagrass more comprehensively and to contribute to the conservation and sustainable management of coastal resources. This study aimed to analyze the species composition and description of seagrass, density and relative density, as well as frequency of occurrence and relative frequency of seagrass species in the coastal waters of Hitalawa Beach, Negeri Oma. The study employed a line transect–quadrat method, consisting of six transects with a total of 30 quadrats. Six seagrass species were recorded, namely Cymodocea rotundata, Halodule pinifolia, Syringodium isoetifolium, Enhalus acoroides, Halophila ovalis, and Thalassia hemprichii. The overall seagrass density reached 89.55 shoots/m², placing the seagrass condition at Hitalawa Beach in scale category 3, namely moderately dense, with a density range of 75–125 shoots/m². The highest frequency of occurrence was recorded for T. hemprichii, which was found in most of the observation plots. Water temperature and salinity across the six transects ranged from 31.2–32.5°C and 27.7–31‰, respectively. The findings indicate that the coastal waters of Hitalawa Beach support a relatively diverse seagrass community with moderately dense seagrass conditions. This study provides updated baseline information on the condition of seagrass beds in the area and may support future coastal resource conservation and management efforts.

Abstract

Sanahu Village is a coastal area where most of the residents rely on fisheries as their primary source of livelihood. However, the growing population and increasing economic demands have led to the rise of environmentally unfriendly fishing practices, including the use of gear that damages aquatic habitats. This situation poses a serious threat to the sustainability of marine resources and the balance of coastal ecosystems. Therefore, efforts to provide understanding, education, and guidance to fishermen regarding the importance of using more environmentally friendly fishing gear are urgently needed. The results of the community service activity indicate that socialization on the use of selective fishing gear with minimal negative impact on the ecosystem is highly necessary and has been positively received by the fishermen of Sanahu Village. In addition to increasing awareness, the successful implementation of eco-friendly fishing tools also requires strong support from local government, non-governmental organizations, environmental activists, and active community participation. Such collaboration is essential to establish effective monitoring systems, ensuring that marine resources can be utilized sustainably while preserving the ecological integrity of coastal waters.
