Konektivitas Ekosistem Mangrove Dan Bentos Di Kabupaten Tangerang

Abstract

Ekosistem mangrove pada pesisir Kabupaten Tangerang telah mengalami kerusakan pada sebagian wilayah dan telah dilakukan upaya rehabilitasi. Biota asosiasi pada kawasan ekosistem mangrove salah satunya adalah makrozoobentos. Penelitian ini bertujuan untuk mengetahui kelimpahan dan keragaman makrozoobentos di kawasan rehabilitasi ekosistem mangrove di Kabupaten Tangerang. Penelitian dilakukan pada bulan Febuari 2022 di tiga desa, yaitu Desa Ketapang, Desa Patramanggala, dan Desa Tanjung Pasir. Analisis data terdiri dari penentuan stasiun pengambilan contoh, pengolahan data vegetasi mangrove, dan pengolahan data makrozoobentos. Hasil analisis komposisi jenis makrozoobentos di Desa Ketapang dan Desa Tanjung Pasir didominasi oleh family Nassaridae dan family Cerithideidae dari kelas Gastropoda, dan di Desa Patramanggala didominasi oleh family Donacidae dari kelas Bivalvia dan family Nassaridae dari kelas Gastropoda. Nilai kepadatan dan nilai indeks ekologi makrozoobentos menunjukkan kondisi ekosistem yang kurang stabil, tertekan dan stress

The mangrove ecosystem in the coast of Tangerang Regency has been damaged in some areas and rehabilitation efforts have been carried out. One of the associated biota in the mangrove ecosystem areas is macrozoobenthos. This study aims to determine the abundance and diversity of macrozoobenthos in the mangrove ecosystem rehabilitation area in Tangerang Regency. The study was conducted in February 2022 in three vilages, namely Ketapang Village, Patramanggala Village, and Tanjung Pasir Village. Data analysis consisted of determining sampling stations, processing mangrove vegetation data, and processing macrozoobentos data. The result of the analysis of the composition of macrozoobenthos spescies in Ketapang Village and Tanjung Pasir Village were dominated by the Nassaridae family and the Cerithideidae family from the Gastropoda class, and Patramanggala Village was dominated by the Donacidae family from the BIvalvia class and the Nassaridae family from the Gastropoda class. The density value and ecological index value of macrozoobenthos indicate an unstable, deperessed and stressed ecosystem condition
