<![CDATA[Seagrasses are flowering plants (angiosperms) that live on a substrate of sand, muddy sand, and sand mixed with coral fragments. Seagrass beds have an important role both for supports the life of various types of marine biota as well as protein source for the coastal community. The purposes of this study were to find out the types of seagrasses and to assess seagrass bed conditions around Lantung village waters. The line transect quadrat method was using for data collection. Four transects were laid perpendicular from the sea to the shoreline. A 50 x 50 cm frame was used to asstimet seagrass percent cover and laid every ten meters along the transect line. This study found 7 species of seagrass namely Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Syringodium isoetifolium, Halodule pinifolia, Halophila decipiens, and Halophila ovalis. The average value of seagrass percent cover at the location was 66.44% and it was categorized as ‘healthy’. The environmental parameters values were 29.86°C, 29.05‰ and 8.45 for temperature, salinity and pH respectively.Keywords: Lantung, seagrass, health condition, percent coverABSTRAK Lamun adalah tumbuh-tumbuhan berbunga (angiospermae) yang hidup pada substrat pasir, pasir berlumpur, dan pasir bercampur pecahan karang. Padang lamun memiliki peran penting dalam suatu ekosistem perairan dangkal yang menunjang kehidupan beragam jenis biota laut dan lumbung protein bagi masyarakat. Adapun tujuan dari penelitian ini ialah mengetahui jenis-jenis lamun yang ada di lokasi penelitian dan mengkaji kondisi kesehatan padang lamun dengan teknik pengumpulan data mengunakan metode transek kuadran yang ditarik tegak lurus garis pantai, dengan ukuran frame 50x 50 cm. Hasil penelitian di Perairan Lantung, Kecamatan Wori, Kabupaten Minahasa Utara, Sulawesi Utara ditemukan 7 jenis lamun yaitu Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Syringodium isoetifolium, Halodule pinifolia, Halophila decipiens, dan Halophila ovalis. Nilai rata- rata penutupan lamun pada lokasi penelitian sebesar 66,44% dan di kategorikan sehat. Parameter di Perairan Lantung yaitu suhu, salinitas, pH, dan substrat tergolong baik dengan nilai rata- rata parameter tergolong optimun dan berada pada kisaran baku mutu air laut dan dapat di toleransi lamun dengan nilai suhu 29,86°C, nilai salinitas 29,05‰ dan nilai pH 8,45.Kata kunci: Lantung, lamun, kondisi kesehatan, penutupan]]>
