Abstract

Kawasan pesisir merupakan daerah yang rawan terkena erosi. Mangrove menjadi ekosistem pesisir yang berpengaruh terhadap laju sedimentasi. Keberadaan hutan mangrove dapat membantu menangani erosi di wilayah pesisir. Adanya bentuk perakaran mangrove yang bervariasi dapat memberikan pengaruh yang berbeda terhadap laju sedimentasi. Penelitian ini bertujuan untuk mengetahui perbandingan laju sedimentasi antara mangrove jenis Rhizophora sp. dengan Avicennia sp., serta untuk mengetahui pengaruh perbedaan bentuk akar mangrove terhadap laju sedimentasi. Penelitian dilakukan pada tanggal 7 April – 30 Juli 2018 di kawasan Hutan Mangrove Bedono, Demak. Kegiatan penelitian meliputi penentuan lokasi sampling melalui metode survei, pengukuran laju sedimentasi menggunakan sediment trap , pengukuran parameter fisika kimia dan analisis tekstur sedimen. Lokasi terdiri dari tiga stasiun, masing – masing stasiun terdapat enam titik. Tiga sediment trap diletakkan pada mangrove jenis Rhizophora sp. dan tiga lainnya pada mangrove jenis Avicennia sp. sehingga terdapat delapan belas titik.
