Abstract

Indonesia is known as a maritime country that is rich in various marine biota, both flora and fauna, for example such as seagrass, in the world there are 60 species of seagrass and 12 species are found in Indonesia. This study aims to determine the community structure and percentage of seagrass cover in the waters of Pinasungkulan Village, Tombariri District, Minahasa Regency, this study used the seagrass watch method, observations were made at 2 station points (ST.1 and ST.2) using the equation formula from Cox, 1967. In the waters of Pinasungkulan Village there are 3 types of seagrass, namely Enhalus acoroides, Halodule pinifolia and Cymodocea rotundata. The percentage of seagrass cover in ST.1 was 22.54% and ST.2 was 28.22%, the average value obtained from these two stations was 25.38%. Overall, the community structure of ST.1 species Halodule pinifolia has the highest important value index of 143.46% and ST.2 species Cymodocea rotundata which has the highest important value index of 133.24%. Parameters in the waters of Pinasungkulan Village, Tombariri District, Minahasa Regency have a normal pH and a stable temperature with sand and silt as a substrate. Keywords: seagrass, percentage cover, community structure ABSTRAK Indonesia dikenal sebagai negara maritim yang kaya dengan berbagai biota laut baik flora maupun fauna contonya seperti lamun, di dunia terdapat 60 jenis lamun dan 12 jenisnya terdapat di Indonesia. Dalam penelitian ini bertujuan untuk mengetahui struktur komunitas dan persentase tutupan lamun di perairan Desa Pinasungkulan Kecamatan Tombariri Kabupaten Minahasa, penelitian ini menggunakan metode seagrass watch, pengamatan dilakukan pada 2 titik stasiun (ST.1 dan ST.2) dengan menggunakan rumus persamaan dari Cox, 1967. Di perairan Desa Pinasungkulan terdapat 3 jenis lamun yaitu Enhalus acoroides, Halodule pinifolia dan Cymodocea rotundata. Hasil tutupan persentase lamun pada ST.1 yaitu 22,54% dan ST.2 yaitu 28,22%, nilai rata-rata yang diperoleh dari kedua stasiun ini yaitu 25,38%. Secara keseluruhan struktur komunitas dari ST.1 jenis Halodule pinifolia memiliki indeks nilai penting tertinggi yaitu 143,46% dan ST.2 jenis Cymodocea rotundata yang memiliki indeks nilai penting tertinggi yaitu sebanyak 133,24%. Parameter di periran Desa Pinasungkulan Kecamatan Tombariri Kabupaten minahasa memiliki pH normal dan suhu yang stabil dengan substrat pasir dan pasir lumpuran.

Abstract

The purpose of this study is to analyze the potential conditions of the mangrove ecosystem, land suitability, conditions and perceptions of the Teling village community to be developed as an ecotourism area. The survey of the potential of the mangrove ecosystem used the transect-quadrant method, while the potential for socio-economic conditions, infrastructure and perceptions of the Teling village community was carried out using the interview method. There are 6 (six) types of mangroves found in Teling Village, namely Avicennia officinalis, Bruguiera gymnorrhiza, Rhizophora mucronata, Sonneratia alba and Sonneratia caseolaris. The mangrove species with the highest average density value is R. mucronata at 33.33 individuals/300m², the highest average frequency value is found in the B. gymnorrhiza and R. stylosa species, which is 0.89, the highest average cover value is found in the S. alba species, which is 1.0265 m2/300 m2, the highest average Importance Value Index (INP) is found in the Rhizophora mucronata species, which is 111.0 with the "moderate" category, the average mangrove diversity index of Teling village is 2.66 with the "moderate" category, while the average mangrove evenness index is 0.693 with the "moderate" category. The mangrove tourism suitability index of Teling village is 2.5, which means that this area is "very suitable". Keywords: ecotourism, mangrove, Teling Village ABSTRAK Tujuan dari penelitian ini adalah menganalisa potensi kondisi ekosistem mangrove, kesesuaian lahan, kondisi dan persepsi masyarakat Desa Teling untuk dikembangkan sebagai kawasan ekowisata. Survei potensi ekosistem mangrove menggunakan metode transek-kuadran, sedangkan potensi kondisi sosial ekonomi, infrastruktur dan persepsi masyarakat desa Teling melalui metode wawancara dan pengisian lembar kuisioner. Ada 6 (enam) jenis mangrove yang ditemukan di Desa Teling yaitu Avicennia officinalis, Bruguiera gymnorrhiza, Rhizophora mucronata, Sonneratia alba dan Sonneratia caseolaris. Jenis mangrove dengan nilai rata-rata kepadatan jenis tertinggi adalah Rhizophora mucronata sebesar 33,33 individu/300m², nilai rata-rata frekuensi jenis tertinggi terdapat pada jenis B. gymnorrhiza dan R. stylosa yaitu sebesar 0,89, nilai rata-rata penutupan jenis tertinggi terdapat pada jenis Sonneratia alba yaitu 1,0265 m2/300 m2, rata-rata Indeks Nilai Penting (INP) tertinggi pada jenis Rhizophora mucronata yaitu 111,0 dengan kategori “sedang”, rata-rata indeks keanekaragaman mangrove desa Teling sebesar 2,66 dengan kategori “sedang”, sedangkan rata-rata indeks kemerataan mangrove-nya yaitu 0,693 dengan kategori “sedang”. Indeks kesesuaian wisata mangrove desa Teling adalah 2,5 yang artinya kawasan ini “sangat sesuai” untuk dikembangkan sebagai kawasan ekowisata mangrove. Kata kunci: ekowisata, mangrove, Desa Teling
