PROFIL EKOSISTEM MANGROVE DI AREA REHABILITASI MANGROVE KABUPATEN TANGERANG

Kawasan mangrove di Kabupaten Tangerang adalah kawasan mangrove dalam proses rehabilitasi, yang merupakan upaya  dalam mengatasi permasalahan degradasi mangrove, salah satunya karena alih fungsi lahan. Umumnya, alih fungsi lahan di kawasan mangrove Kabupaten Tangerang dijadikan sebagai lahan tambak. Penelitian ini bertujuan untuk menganalisis jenis mangrove, indeks nilai penting, dan penutupan mangrove yang berada di kawasan mangrove alami dan rehabilitasi Kabupaten Tangerang. Penelitian dilaksanakan dari bulan Februari hingga Maret 2022 ditiga desa (stasiun) yaitu Desa Ketapang, Desa Patramanggala, dan Desa Tanjung Pasir, Kabupaten Tangerang. Pengambilan data vegetasi mangrove berdasarkan tiga kategori yaitu pohon pada transek berukuran 10 × 10 m2, anakan pada transek berukuran 5 × 5 m2, dan semai pada transek berukuran 2 × 2 m2. Hasil penelitian yang didapatkan ditemukan lima jenis mangrove dari tiga desa (stasiun) yaitu Avicennia marina, Avicennia alba, Rhizophora mucronata, Rhizophora stylosa, dan Bruguiera cylindrica. Penutupan mangrove tertinggi di Desa Tanjung Pasir sebesar 80,99% yang dijumpai  pada substasiun 3, masuk dalam kriteria baik dan sangat padat. Penutupan mangrove terendah di Desa Tanjung Pasir terdapat pada substasiun 2 yaitu 34,91%, masuk dalam kategori rusak dan jarang. Persen tutupan mangrove tertinggi dari tiga desa (stasiun) yaitu terdapat pada substasiun 3 berdasarkan Kepmen LH No. 201 tahun 2004 masuk kedalam kategori baik dan sangat padat. Kata kunci: mangrove, pesisir, penutupan kanopi.The mangrove area in Tangerang Regency is a mangrove area in the rehabilitation process, which is an effort to overcome the problem of mangrove degradation, one of which is due to land conversion. Ponds dominate land use change in the mangrove area of ​​Tangerang Regency. This study aims to analyze mangrove species, importance value index, and mangrove cover in the natural mangrove area and rehabilitation of Tangerang Regency. The research was conducted from February to March 2022 in three villages (stations): Ketapang Village, Patramanggala Village, and Tanjung Pasir Village, Tangerang Regency. Mangrove vegetation data was collected based on three categories: trees on a 10 × 10 m2 transect, saplings on a 5 × 5 m2 transect, and seedlings on a 2 × 2 m2 transect. The results of the study found five types of mangroves from three villages (stations), namely Avicennia marina, Avicennia alba, Rhizophora mucronata, Rhizophora stylosa, and Bruguiera cylindrica. The highest mangrove cover was in Tanjung Pasir Village of 80,99% which was found in substation 3, included in the good and very dense criteria. The lowest mangrove cover in Tanjung Pasir Village was at substation 2, namely 34,91%, included in the damaged and rare category. The highest percentage of mangrove cover of the three villages (stations) was located at substation 3 based on Minister of Environment Decree No. 201 of 2004 was included in the good and very dense category.
