Description Ekosistem mangrove merupakan salah satu ekosistem pesisir dengan tingkat produktivitas yang tinggi, sehingga keberadaannya dapat memperkaya kawasan pesisir dan menjaga keseimbangan ekosistem. Penelitian ini bertujuan untuk menjelaskan perubahan luasan dan sebaran ekosistem mangrove dalam kurun waktu 20 tahun, yakni dari tahun 2000 sampai dengan 2020 dan untuk mengetahui kondisi vegetasi ekosistem mangrove di Pulau Tanakeke. Penelitian ini dilakukan pada bulan Januari hingga April 2020 di Pulau Tanakeke. Penentuan lokasi penelitian menggunakan metode purposive sampling. Analisis perubahan luasan ekosistem mangrove dari tahun 2000 sampai 2020 menggunakan metode supervised classification dengan analisis maximum likelihood, sedangkan kondisi vegetasi ekosistem mangrove menggunakan metode analisis indeks nilai penting (INP) dan indeks keanekaragaman jenis. Hasil penelitian menunjukkan bahwa ekosistem mangrove di Pulau Tanakeke dari tahun 2000 sampai 2020 mengalami degradasi seluas -337,41 ha (28,32% dari luas tahun 2000). Pada lokasi penelitian ditemukan 9 jenis mangrove, yaitu Bruguiera gymnorrhiza, Ceriops tagal, Rhizophora stylosa, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, Phemphis acidula, Lumnitzera racemosa dan Ceriops decandra. Mangrove jenis Rhizophora mucronata memiliki indeks nilai penting tertinggi yaitu sebesar 192,55%, sementara untuk keanekaragaman jenis secara umum tergolong rendah.
Mangrove ecosystem is one of the coastal ecosystems with a high level of productivity, so its existence can be enrich coastal areas and maintain the balance of ecosystems. This study aims to explain the changes in the extent and distribution of mangrove ecosystems within 20 years, from 2000 to 2020 and to know the condition of mangrove ecosystem vegetation in Tanakeke Island. This research was conducted from January to April 2020 in Tanakeke Island. Determination of research location using purposive sampling method. Analysis of changes in mangrove ecosystem area from 2000 to 2020 using supervised classification method with maximum likelihood analysis, while the condition of mangrove ecosystem vegetation using important value index (INP) analyst method and species diversity index. The results showed that mangrove ecosystems in Tanakeke Island from 2000 to 2020 degraded for about -337.41 ha (28.32% of the area in 2000). At the research site found 9 types of mangroves, such as Bruguiera gymnorrhiza, Ceriops tagal, Rhizophora stylosa, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, Phemphis acidula, Lumnitzera racemosa and Ceriops decandra. Mangrove type Rhizophora mucronata has the highest important value index of 192.55%, while for diversity of species in general is relatively low.
