Abstract

Tuna hand lines have been used by fishermen to catch big pelagic species. Most of the fishermen still used natural bait in their catching operation, and just a few of them who used artificial bait. Therefore, the objective of this research was to study the effect of artificial bait toward the capture of tuna hand line. The artificial bait which been used in this research was non comercial bait, made from a plastic bag with silver color. The natural bait that been used was fish meat. This research was done by descriptive method based on case study; worked on October 2012 until January 2013 in Molucca Sea; hand line with artificial bait caugth 113 fish and with natural bait 67 fish. Analysis of t-test showed that t0 = 4,55 > t0,05;5 = 2,080; which means that the use of artificial bait could affected the catch of tuna hand line© Pancing ulur tuna biasa digunakan oleh nelayan untuk menangkap ikan pelagis besar. Umumnya mereka masih menggunakan umpan alami; masih sedikit nelayan yang menggunakan umpan buatan dalam operasi penangkapannya. Oleh karena itu, penelitian ini bertujuan untuk mempelajari pengaruh penggunaan umpan buatan terhadap hasil tangkapan pancing ulur tuna. Umpan buatan yang digunakan adalah umpan non-komersial (buatan sendiri) yang terbuat dari bahan plastik berwarna perak mengkilat, sedangkan umpan alami yang digunakan adalah daging ikan. Penelitian ini dilakukan dengan metode deskriptif yang didasarkan pada studi kasus yang dilaksanapan pada bulan Oktober 2012 sampai Januari 2013 di perairan Laut Maluku. Pancing ulur tuna dengan umpan buatan menangkap 113 ekor dan dengan umpan alami menangkap 67 ekor. Uji-t menunjukan bahwa t0 = 4,55 > t0,05;5 = 2,080 yang berarti bahwa penggunaan umpan buatan berpengaruh terhadap hasil tangkapan pancing ulur tuna©

Abstract

Hutan mangrove memiliki fungsi dan manfaat yang sangat besar, baik ditinjau secara fisik, kimia, biologi, ekonomi, bahkan wahana wisata.Penelitian ini bertujuan untuk Mengukur tingkat keberhasilan hidup pohon mangrove yang ditanam di lokasi penelitian, Mengukur tingkat pertumbuhan pohon mangrove di lokasi penelitian. Hasil penelitian mendapatkan bahwa Tingkat keberhasilan hidup atau Survival Rate (SR) pada tiga lokasi penelitian adalah sebagai berikut : SR Dagho : 25.9, SR Matahit : 10.45, SR Pasirpanjang : 46.4. Pengukuran Tingkat pertumbuhan Mangrove atau Growth Rate (GR) hanya dilakukan di pasirpanjang. Adapun  GR Pasirpanjang berkisar antara 2,67 cm sampai dengan 17,02 cm.

Abstract

Penyakit infeksi merupakan salah satu penyakit yang menyebabkan mortalitas dan morbiditas di dunia yang dapat diterapi menggunakan antibotik. Adanya resistensi dapat mengancam efektivitas antibiotik. Penelitian ini bertujuan untuk mencari kandidat antibiotik yang bersumber dari fungi tanah muara yang diuji aktivitasnya terhadap bakteri Pseudomonas aeruginosa. Ekosistem tanah muara  mangrove memiliki kondisi ekstrem sehingga menuntut mikroorganisme untuk bertahan hidup dengan memproduksi senyawa antibiotik untuk bersaing dengan mikroorganisme lain. Sampel tanah diambil dari Muara Sungai Desa Kalinaun, Kecamatan Likupang Timur, Kabupaten Minahasa Utara, Provinsi Sulawesi Utara. Sampel tanah yang didapat sebanyak empat isolat fungi berpotensi dalam menghambat bakteri uji, yaitu IS2-BTG11-1-1, IS2-BTG11-2-1, IS2-BTG11-2-2, IS2-BTG11-2-3. Keempat isolat tersebut dilakukan fermentasi selama 14 hari lalu diekstraksi dengan pelarut etil asetat. Setelah didapatkan ekstrak etil asetat, dilakukan skrining fitokimia dan didapatkan hasil bahwa keempat ekstrak mengandung senyawa golongan terpenoid. Setelah dilakukan skrining fitokimia, dilakukan uji aktivitas antibakteri menggunakan metode mikrodilusi. Uji mikrodilusi dilakukan dengan konsentrasi tunggal 50 µg/mL. Berdasarkan uji mikrodilusi, keempat ekstrak fungi tanah muara memberikan aktivitas penghambatan berturut-turut dari terbesar ke terkecil : IS2-BTG11-2-3 (50,9% ± 7,6); IS2-BTG11-2-1 (49,8% ± 13,5); IS2-BTG11-1-1 (34,4% ± 2,4); IS2-BTG11-2-2 (37,2% ± 7,7). Pada penelitian ini senyawa yang berperan sebagai antibakteri belum bisa dipastikan, sehingga membutuhkan penelitian lebih lanjut. Kata Kunci: Antibakteri, Pseudomonas aeruginosa, Fungi Tanah Muara, Mikrodilusi, Desa Kalinaun  Infectious diseases are one of the leading causes of mortality and morbidity in the world that  can be treated with antibiotics. The existence of resistance can threaten the effectiveness of antibiotics. This study aims to find new antibiotic candidates from fungi in estuary soils and tested the activity against Pseudomonas aeruginosa bacteria. Estuary soil ecosystems have extreme conditions that require microorganisms to be able to survive Soil samples were taken from the Estuary of the Kalinaun Village, East Likupang District, North Minahasa Regency, North Sulawesi Province. Soil samples obtained were 4 isolates of fungi that had the potential bacteria inhibition, namely IS2-BTG11-1-1, IS2-BTG11-2-1, IS2-BTG11-2-2, IS2-BTG11-2-3. Four isolates were fermented for 14 days and extracted with ethyl acetate solvent. Phytochemical screening of the extract was carried out and the results showed that the four extracts contained terpenoid compounds. Antibacterial activity was tested using the microdilution methods with a single concentration of 50 µg/mL. Based on the microdilution test, four estuary soil fungal extracts gave inhibitory activity from the largest to the smallest: IS2-BTG11-2-3 (50.9% ± 7.6); IS2-BTG11-2-1 (49.8% ± 13.5); IS2-BTG11-1-1 (34.4% ± 2.4); IS2-BTG11-2-2 (37.2% ± 7.7). In this study, the compound that acts as an antibacterial has not been determined, so it requires further research.

Abstract

Pseudomonas aeruginosa is a bacterial pathogen that causes various kinds of infections. The use of antibiotics is usually done to treat the infection. However, Pseudomonas aeruginosa has various resistance abilities that can avoid the efficacy of antibiotics. The emergence of drug resistance events encourages the need for the discovery of new antibiotic drugs, one of which comes from fungals secondary metabolite. Soil fungi from mangrove ecosystems have not been studied much. Interestingly, these soil fungi have unique adaptive responses. This response also affects the secondary metabolites it contains. Knowing this information, mangrove soil samples were cultured on fungi media which were then tested against Pseudomonas aeruginosa through antagonist test and microdilution test. Three fungal cultures with yeast characteristics were obtained and each of the secondary metabolite ethyl acetate extracts of these three fungi had antibacterial activity. The antibacterial activity was indicated by the % inhibition parameter. The terpenoid content in fungal cultures may be responsible for the antibacterial activity against Pseudomonas aeruginosa. This research is an initial screening of the search for new antibiotic candidates, so further research study such as isolation and species determination needs to be done.
