Abstract

This research was conducted to qualitatively analyze the phytochemical content of kepok banana (Musa paradisiaca) peel extract and the effectivity of the extract as antibacterial against Aeromonas hydrophila. Fresh yellow color banana peels were washed, drained, then cut into pieces, crushed and dried at room temperature. Extraction was carried out by maceration method with 70% and 95% ethanol as solvent. A total of 90 g was put in an elemeyer glass then added with solvent until all the banana peels were submerged. The immersion time was 3x24 hours at room temperature while stirring occasionally so that the extraction occurs properly. Furthermore, the extract was filtered with Whatman paper no. 42 to separate the residue from the filtrate. The filtrate was then concentrated using a rotary evaporator. Phytochemical examined consisted of alkaloid, flavonoid, sternoid, triterpenoid, saponin, and tannin. Inhibition test against A. hydrophila was carried out by disc diffusion method using 5 different extract concentrations as treatments, namely A: 0%, B:10%, C:20%, D:30%, E:40%, F:50%. In the inhibition test, the paper disc was dipped in each treatment and then placed on agar media previously stocked with bacteria. The inhibitory zone was measured based on the clear area formed around the disc and observed at 24, 48, and 72 hours. Phytochemical test found that phenol and tannin were only detected in extracts with 95% ethanol while terpenoids and steroids were only found in  ethanol70%.  Flavonoid was detected in the extract using either ethanol70% and 95%. The results of the inhibitory test showed that the kepok banana peel extract could inhibit the growth of A. hydrophila bacteria after 48 hours of incubation. Inhibition zones formed at both 48 hours and 72 hours tended to increase in line with the increase in concentration even though the inhibitory power produced was categorized as "medium".

Abstract

The objective of this research was to obtain probiotic bacteria isolated from the digestive tract of catfish Clarias batracus, to evaluate its effect on growth performances and survival rate of carp. After purified, the bacteria was identified through biochemical tests and selection was carried out through proteolytic, amylolytic, cellulolytic, tests as well as pathogenicity test. Probiotic candidate was administered orally to fish at different concentrations. The fish were fed for 30 days respectively as much as 3% of body weight per day with feeding frequency of two times a day. The results showed that addition of probiotics into feed significantly increased growth performance but not survival rate.Keywords: Probiotic, Clarias batracus,  growth performance, aquaculture. ABSTRAKTujuan dari penelitian ini adalah untuk mendapatkan bakteri probiotik yang diisolasi dari saluran pencernaan ikan lele Clarias batracus, dan mengevaluasi pengaruhnya terhadap kinerja pertumbuhan dan kelangsungan hidup benih ikan mas.

Abstract

Soft corals ar known to have a variety of bioactivity capabilities, one of them is antibacterial. Antibacterial is a compound that can interfere with the growth of bacteria or even kill the bacteria. The soft coral samples, Lobophytum sp., obtained from  Pangalisang, Bunaken Island, wer extracted by evaporative process, then fractionated into three fractions by aqueous partitioning technique with aqueous solvents, ethyl acetate, methanol and n-hexane. Antibacterial testing, with bacterial samples of Pseudomonas aeruginaso and Staphylococcus aureus were analyzed by agar diffusion / Kirby Bauer method. The results of the experiment showed that every fraction had antibacterial activity, where the largest activity was produce at concentration of 50 disc paper sampes with  7 mm (water fraction), 8 mm ( metanol fraction), 7,2 mm (n-hexane fraction) in Pseudomonas aeruginosa and 7 mm (water fraction), 8,7 mm ( metanol fraction) in Staphylcoccus aureus. It can be concluded that the  inhibition zone from soft corals, Lobophytum sp., is classified as a weak activity, so it does not potential to be developed into an antibacterial drug.Keywords: Antibacterial, Lobophytum sp., Pseudomonas aeruginosa, Staphylcoccus aureus.ABSTRAKKarang lunak diketahui mempunyai berbagai bioaktivitas salah satunya antibakteri. Antibakteri merupakan senyawa yang dapat mengganggu pertumbuhan atau bahkan dapat mematikan bakteri. Sampel karang lunak Lobophytum sp. yang diperoleh dari perairan Pangalisang Pulau Bunaken diambil ekstrak kentalnya melalui proses evaporasi, selanjutnya difraksinasi menjadi tiga fraksi dengan teknik partisi cair dengan pelarut aquades, etil asetat, metanol dan n-heksan. Pengujian antibakteri terhadap bakteri Pseudomonas aeruginosa  dan Staphylococcus aureus dianalisis dengan metode difusi agar (disc diffusion Kirby and Bauer). Hasil penelitian menunjukan ketiga fraksi memiliki aktivitas antibakteri, dimana aktivitas terbesar dihasilkan pada konsentrasi sampel dalam kertas cakram 50 μl dengan zona hambat 7mm (fraksi air), 8 mm (fraksi metanol), 7,2 mm (fraksi n-heksan) pada Pseudomonas aeruginosa dan 7 mm (fraksi air), 8,7 mm (fraksi metanol) pada Staphylococcuss aureus. Dapat disimpulkan bahwa zona hambat yang dihasilkan karang lunak Lobophytum sp. tergolong lemah sehingga tidak berpotensi untuk dikembangkan sebagai obat antibakteri.Kata kunci: Antibakteri, Lobophytum sp., Pseudomonas aeruginosa, Staphylcoccus aureus.

Abstract

The objective of research was to isolate probiotic bacteria from catfish intestine and to examine its effects on the growth and resistance of carp against Aeromonas hydrophila.  The probiotic isolated from intestine was grown on MRS agar.  Fish used in this research was juvenile of carp with an average weight of 5.5 g obtained from Freshwater Aquaculture Board at Tatelu Village, North Sulawesi Province.  Before running the experiment, the juveniles were adapted for one weeks in 15 glass aquaria at a density of 15 individuals each.  After acclimatization, the fish were fed diet supplemented with probiotic at different concentrations namely 1x109 , 1x108 , 1x107,  1x106 cfu/mL for three weeks. The fish were fed two times a dayat 08.00 am and 17.00 pm with a dose of 5% of body weight per day. At the end of feeding, the fish were challenged with A. hydrophila.  Data collected included average growth rate, absolute growth, feed efficiency, and food conversion ratio.  Research results found that the addition of probiotic into feed was  able to increase growth and feed efficiency and reduce food conversion ratio as well (p<0.01). The best growth, feed efficiency and food conversion ratio were obtained in fish fed diet added with probiotic bacteria at 1x108 cfu/mL.  The highest survival rate was also observed in fish probiotic diet containing 1x108 cfu/mL.  As conclusion, probiotic bacteria isolated from catfish intestine was potential to improve growth, feed efficiency, reduce food conversion ratio and increase resistance of fish against bacterial pathogen.Keywords: probiotic, carp, Aeromonas hydrophila, feed efficiency, food conversion ratioABSTRAKPenelitian ini bertujuan untuk mengisolasi bakteri probiotik dari usus ikan lele dan menguji pengaruh pemberian probiotik dari usus ikan lele terhadap pertumbuhan dan resistensi ikan mas terhadap infeksi Aeromonas hydrophilla.
