Abstract

Pulau Payung merupakan kawasan hutan lindung menurut SK Menhut No.866/Menhut-II/2014. Keberadaan mangrove Pulau Payung di sekitar muara Sungai Musi, berada di alur pelayaran sehingga mangrove tersebut dapat mudah dijangkau. IUCN (International Union for Conservation of Nature and Natural Resources) menyatakan mangrove R.apiculata, A.alba, A.marina, A.officinalis dan Kandelia candel masuk kedalam kategori LC (Least Concern). Penelitian telah dilaksanakan pada bulan Oktober - Desember 2022. Penelitian ini bertujuan untuk Menganalisis keragaman genetik dan hubungan kekerabatan mangrove R. apiculata, A. alba, A. marina, A. officinalis dan K. candel menggunakan metode Sequence Related Amplified Polymorphism (SRAP). Hasil penelitian ini memiliki goodness of fit r=0,92603; Mantel t-test t = 19.9368 ;Probability random Z <observed Z: p = 1.0000. Nilai diversitas gen berkisar dari 0,8855 hingga 0,9188 dengan rerata 0,8999. dan nilai Polymorphic Information Content (PIC) berkisar antara 0,8645 hingga 0,9131 dengan rerata sebesar 0,8917. Hasil analisis dendogram 31 genotipe mangrove terbagi ke dalam lima klaster dengan koefisien kemiripan sebesar 0,86. Klaster pertama terdiri dari 14 aksesi yaitu 6 K. candel dan 8 R. apiculata, klaster kedua terdiri dari 3 aksesi yaitu A. alba, klaster ketiga 9 aksesi yaitu 3 A. alba, 3 A. marina 3 A. officinalis, klaster keempat terdiri dari 3 aksesi A. alba dan klaster kelima 2 aksesi A. alba. Seluruh marka SRAP dalam penelitian ini terbukti cukup informatif dan sangat sesuai dengan dibuktikan nilai r > 0,9 dan PIC > 0,7.
