Abstrak

Abstrak Target pemerintah dalam bidang perikanan adalah meningkatkan produksi perikanan sebesar 300% hingga tahun 2015. Salah satu kegiatan yang dilakukan dalam meningkatkan produksi perikananadalah melalui proses budidaya. Dalam proses budidaya, salah satu hambatan yang sering dihadapi adalah timbulnya penyakit, Penyakit yang disebabkan oleh bakteri dapat menyebabkan kerugian yang cukup besar, bahkan kadang dapat menyebabkan proses budidaya terhenti. Selama ini pencegahan terhadap serangan bakteri pada umumnya dilakukan dengan pemberian antibiotik dan bahan kimia, pemberian antibiotik secara terus menerus dapat menyebabkan organisme patogen menjadi resisten, sehingga penggunaan antimikroba menjadi tidak efektif. Ekstrak dan bahan mentah dari mangrove telah banyak dimanfaatkan oleh masyarakat pesisir untuk keperluan obat-obatan alamiah, baik bagian daun, buah, maupun kulit batangnya.Penelitian dilaksanakan pada bulan November sampai dengan Desember 2011. Hasil penelitian menunjukan (1) Daun bagian pucuk mangrove jenis Rhizophora mucronata merupakan bagian daun yang paling efektif digunakan sebagai antibakteri alami, (2) Pelarut etil asetat efektif digunakan sebagai larutan penyari untuk mengekstrak daun mangrove (Rhizophora mucronata), (3) Ekstrak daun mangrove (Rhizophora mucronata) memiliki potensi dalam menghambat bakteri Vibrio harveyi, (4)Ekstrak daun mangrove (Rhizophora mucronata) dapat menghambat bakteri V. harveyi pada konsentrasi 300 ppm di uji MIC dan 200 ppm pada uji LC-50. Kata kunci : Ekstrak Rhizophora mucronata ,Antibakteri, Aeromonas salmonicida Vibrio harveyi. Abstract The target of government in fishery sector is increase the production of fishery until 2015 is 300%. One of the activity that had done in increase the fishery product is cultivating process. In cultivating process, the one of common obstacle is disease. The disease that caused by bacteria causing a big loss. All this time the common avoidance toward bacteria attact is by giving antibiotic and chemical, the continuity of giving the chemical causing the patogen organism became resistant. The escence and direct material of mangrove was using by littoral society as natural medichine, the part of leave, fruit, and also bark of the steam. The research was conducted on November until December in 2011. Methodology of this research used maserasi, sensitivity testing, in vitro testing, TPC (Total Plate Count) and LC 50. The result of this research showed : (1) The tip of mangrove leave type of Rhizophora muncronata is the most effective part to apply as natural antibiotic, (2) Etil acetate solvent is more effective to use as finding liquid to extracting mongrove leave (Rhizophora muncronata), (3) Mangrove leave escence (Rhizophora muncronata) has a potential in constraining Vibrio harveyi, (4) The leave escence (Rhizophora muncronata) of mangrove in constraining Vibrio harveyibacteria result of MIC 300 ppm and LC-50 testing 200 ppm. Keyword : Rhizophora muncronata escence, Antibiotic, Aeromonas salmonicida, Vibrio harveyi.
