Abstract

Penelitian ini menggunakan metode deskriptif, diperoleh dari hasil analisis seluruh pengujian kemudian dideskripsikan hasil uji masing-masing parameter berdasarkan perlakuan dan diklasifikasikan berdasarkan nilai analisa hasil uji. Perlakuan berdasarkan pada perbedaan konsentrasi ekstrak lamun yaitu 500 p p m, 1.000 ppm, 1.500 ppm dan 2.000 ppm. Parameter yang diamati yaitu aktivitas antioksidan, antibakteri, kandungan fitokimia, dan fraksinasi lamun H.uninervis. Hasil penelitian menunjukkan bahwa ekstrak kasar lamun jenis H.uninervis memiliki kandungan aktivitas antioksidan yang lemah yaitu 1.575 ppm dan terdapat beberapa kandungan senyawa fitokimia yaitu flavonoid, alkaloid, steriod, tanin dan fenol. Aktivitas antibakteri menunjukkan bahwa ekstrak lamun dapat menghambat beberapa jenis bakteri Gram negatif (Aeromonas hydrophila dan Vibrio harveyi) dan bakteri Gram positif {Bacillus subtilis dan Listeria Monocytogenes). Sedangkan untuk aktivitas penghambatan tertinggi terdapat pada jenis bakteri Gram positif (Bacillus subtilis dan Listeria Monocytogenes) antara 7 mm sampai 9 mm.
