Abstract

Water quality plays an important role in maintaining and increasing fish production. Tilapia (Oreochromis niloticus) is one of Indonesia's freshwater fish that has economic value. To increase production, tilapia cultivation is carried out intensively, characterized by high stocking density and provision of protein-rich feed. Good water quality control and feeding are key to the success of this intensive culture. Biofloc technology is one of the appropriate technologies for intensive tilapia rearing since fish can live at high densities and have a wide environmental tolerance. biofloc technology is an alternative solution to problems in overcoming cultivation waste such as ammonia and nitrite. Based on the above, this study was conducted to determine the effectiveness of the biofloc system in converting ammonia compounds, improving water quality in the aquaculture environment, and understanding the relationship between water quality and tilapia growth. The research was conducted for 60 days to measure several water quality parameters, namely temperature, dissolved oxygen, acidity (pH), and ammonia, and to observe the growth parameters of tilapia. The treatment applied in this study was the addition of probiotics in feed with four treatments and three replications. The results showed that the biofloc system's water quality is tolerant to tilapia growth. The best growth results in treatment A with each value of absolute weight 14.70±0.10d, absolute length 6.70 ± 0.10d, specific growth rate 3.87±0.01c, and survival rate 100±0.00b

Abstract

Lactic Acid Bacteria (LAB) are probiotic-forming bacteria that have characteristics, like be able to ferment sugar or carbohydrates and produce lactic acid as the final product of fermentation. The purpose of this study was to obtain isolates of lactic acid bacteria from the digestive tract of Asian Swamp Eel (Monopterus albus) and to determine the inhibition produced by these lactic acid bacteria in inhibiting pathogenic bacteria such as Aeromonas hydrophila and Pseudomonas sp. The method was used in this study is experimental method, by taking the digestive tract of Asian Swamp Eel and then identifying the lactic acid bacteria and characterized by morphological and biochemical characteristics and tested of the antagonist against the pathogenic bacteria A.hydrophila and Pseudomonas sp. using the Kirby Bauer disc method (disc method). From the research results obtained 5 types of candidate lactic acid bacteria with each code BL121, BL263, BL142, BL242 and BL342. The five isolates of lactic acid bacteria were able to inhibit A.hydrophila and Pseudomonas sp. with a Inhibition range of 8-16 mm. Based on the results of the study, there were three isolates that had inhibitory power against bacteria A. hydrophila (12-16 mm) and Pseudomonas sp (11-13 mm) with codes BL121, BL263 and BL142 and were classified as strong. The identification results obtained are bacteria from the genus Bacillus sp.

Abstract

Penelitian ini bertujuan untuk mengetahui gejala klinis ikan komet yang terinfeksi bakteri Aeromonas hydrophila dan pascapengobatan dengan larutan propolis. Metode yang digunakan adalah metode eksperimen dengan menerapkan rancangan acak lengkap (RAL) dengan satu faktor lima taraf perlakuan dan tiga kali ulangan perlakuan. Perlakuan tersebut adalah adalah Kn (tidak terinfeksi A.hydrophila dan tidak diobati propolis), Kp (terinfeksi A. hydrophila  tetapi tidak diobati propolis), sedangkan ikan terinfeksi A.hydrophila diobati dengan propolis dosis P1 (700 ppm), P2 (800 ppm), dan P3 (900 ppm). Pengobatan dilakukan dengan cara penyuntikan propolis pada ikan yang terinfeksi A.hydrophila di bagian intramuscular sebanyak 0,1 ml. Bahan uji yang digunakan adalah ikan komet (Carassius auratus) ukuran 8-10 cm sebanyak 150 ekor. Hasil penelitian menunjukkan bahwa ikan yang terinfeksi bakteri A.hydrophila menunjukkan gejala klinis sirip ekor gripis, bercak merah, mata menonjol (exopthalmia), perut mengembung (dropsy), sisik tubuh lepas. Setelah 14 hari pascapengobatan dengan larutan propolis perlakuan terbaik adalah perlakuan P2 dosis (800 ppm) mengalami kondisi pemulihan mendekati gejala klinis kondisi ikan normal terlihat dari warna tubuh cerah, produksi lendir normal, sirip ekor utuh, tidak terdapat mata menonjol (exopthalmia), dan perut tidak mengembung (dropsy).
