Abstract

This study was aimed to identify the potential use of active compounds extracted from Staurogyne sp as an antibacterial agent to control disease-causing bacteria in fish. Staurogyne sp, an aquatic plant collected from Bantimurung, South Sulawesi were subjected to allelochemical compound. Plant extracts were tested to five bacteria including four types of bacterial pathogen, such as Aeromonas hydrophilla, Edwardsiella ictaluri, Streptococcus agalactiae, and Flavobacterium columnare, and one bacterial sensing quoroum, Chromobacterium violaceum. Based on phytochemical analysis, Staurogyne’s extracts derived from both stem and root contained flavonoids, phenols, and antioxidants compounds with the concentration of 0.018 mgQE/g, 0.3471 mgGAE/g, and  1004,391 IC50 µg/mL, respectively. In addition, Staurogyne plant extracts derived from both their stem and root has also produced both saponins and glycosides compounds. Plant extracts derived from Staurogyne’s leaves revealed three major chemical compounds such as flavonoids (0.77 mgQE/g), phenol (0.0629 mgGAE/g), and glycosides (+). However, no antioxidants and saponin compounds were detected.  Applying plant extracts as an antibacterial on five disease-causing bacteria causing diseases in aquaculture, such as Aeromonas Hydrophilla, Edwardsiella ictaluri, Streptococcus agalactiae, Flavobacterium columnare, and Chromobacterium violaceum bacterials revealed that at concentration of 0.1 g the Staurogyne sp extracts did not influence all the bacterials growth. However, by application of plant extract at concentration of 0.2 g on the growth media,three out of 5 tested bacterials (Aeromonas hydrophilla, Edwardsiella ictaluri, and Streptococcus agalactiae) showed intermediate inhibition responses on bacterial growth. The growth of remaining two bacterials pathogen, Flavobacterium columnare and Chromobacterium violaceum at 0.2 g plant extract of Staurogyne sp was not affected. This study revealed that the use of active compound derived from Staurogyne sp would be potential to be used in inhibiting disease-causing bacterial in fish in future. However, optimum concentration of the plant extracts, in particular on the inhibition of the growth of disease-causing bacteria in fish is still needed to adjust.Key words: Antibacterial, aquatic plant, Staurogyne sp, fish disease

Abstract

Rumput laut merupakan salah satu komoditi budidaya laut yang menjadi unggulan Kab. Pangkep. Budidaya rumput laut K. alvarezii telah lama diusahakan oleh masyarakat di Kab. Pangkep, namun masih ditemui beberapa kendala dan permasalahan sehingga hasil yang diperoleh oleh petani dari usaha rumput laut belum maksimal. Penelitian ini bertujuan mengkaji strategi pengelolaan budidaya rumput laut di Kab. Pangkep. Penelitian dilaksanakan pada empat wilayah budidaya rumput laut di Kab. Pangkep yaitu Kec. Ma’rang, Kec. Mandalle, Kec. Segeri dan Kec. Labakkang. Data penelitian dikumpulkan menggunakan beberapa metode yaitu: Focus Group Discussion (FGD), observasi, wawancara terstruktur, dan studi literatur. Data hasil penelitian dianalisis menggunakan analisis SWOT untuk menentukan strategi pengelolaan budidaya rumput laut. Berdasarkan hasil analisis SWOT terhadap kondisi lingkungan internal dan eksternal yang berpengaruh pada kegiatan budidaya rumput laut di Kab. Pangkep, maka strategi yang terpilih adalah strategi yang memanfaatkan faktor peluang untuk mengatasi faktor kelemahan (strategi WO). Rumusan strategi WO yang diusulkan untuk perbaikan dan pengembangan budidaya rumput laut di Kab. Pangkep antara lain; peningkatkan bimbingan teknis dan pendampingan oleh penyuluh pada kegiatan usaha budidaya rumput laut; pembentukan usaha produksi “bibit sebar” hasil kaidah seleksi secara konsisten dan berkesinambungan di setiap kawasan/zona budidaya; kajian dan penetapan musim tanam sepanjang tahun sesuai karakter perairan dan musim di setiap zona budidaya.

Abstract

A total of 21 aquatic plant species were collected from Bantimurung waterfall areas, South Sulawesi, Indonesia, in October 2017. These plant materials were subjected to both species and phytochemicals identification. The aims of this study were to determine the species or taxonomic rank of Indonesian aquatic plants collected from Bantimurung waterfall, South Sulawesi, Indonesia and to identify their chemical compounds (phytochemicals) as a candidate for new herbal medicine. Plant genetic materials used in this study were collected from Bantimurung Bulusaraung waterfall and were then identified based on standard botanical techniques for species identification in the Herbarium Bogoriense, Research center for Biology Indonesian Institute of Science (LIPI), Cibinong, West Java. The samples were subjected to the phytochemistry screening such as alkaloids, flavonoids, tannins, saponins, glycosides, terpenoids and anthraquinone followed the procedures of Indonesian Materia Medika and Harborne.  Results showed that all collected aquatic plant samples were able to be identified, including their species names. Phytochemical screening of each sample revealed the presence of glycoside in all of the tested species. However, no alkaloids, anthraquinones, and terpenoids were observed in those tested plant samples. Of the total 21 aquatic plants, 14 species contained flavonoids, 8 species contained phenol compound, and 10 species contained saponins. Among these species Donnax canniformis possessed good antioxidant activity, which correlated to its total phenolic and flavonoid contents. Our results would be beneficial for any future effort in the development of new herbal drugs derived from aquatic plants.

Abstract

Kualitas dan pertumbuhan larva udang vaname sangat dipengaruhi oleh proses dan frekuensi molting, dimana pertumbuhan erat kaitannya dengan proses pergantian cangkang. Kalsium hidroksida Ca(OH)2 merupakan salah satu mineral kalsium yang berhubungan dengan kadar kalsium kulit dan kadar kalsium lingkungan seiring pertukaran kalsium secara terus-menerus antara tubuh dan lingkungan. Tujuan penelitian ini adalah mengevaluasi akselerasi dan frekuensi molting larva udang vaname serta pengaruh lanjut Kalsium Hidroksida Ca(OH)2 terhadap laju pertumbuhan larva udang vaname. Desain penelitian adalah eksperimental menggunakan Rancangan Acak Lengkap dengan 4 taraf dosis Ca(OH)2 : A. Tanpa penambahan Ca(OH)2 (kontrol), B. 2 mg/ L air, C. 4 mg/ L air, dan D. 6 mg/L air. Hasil penelitian menunjukkan bahwa dosis Ca(OH)2 sebanyak 4 mg/L air menunjukkan intensitas/persentase molting sebesar 67%, laju pertumbuhan berat mutlak sebesar 2.35 mg, pertumbuhan panjang mutlak sebesar 4,93 mm, dan tingkat kelulushidupan udang (SR) sebesar 49%.
