Abstract

The use of Bacillus amyloliquefaciens based fungicide has increased along with the modernization of agriculture. On the other hand, freshwater culture is generally juxtaposed with agricultural land. This study was conducted to determine the fungicide's sublethal effect on the survival and haematologist of common carp and tilapia as non-target organisms. The method used was a completely randomized design (CRD) with 4 treatments and 3 replications. The treatments used are: (A) control (0 ppm fungicide), (B) 0.5 ppm fungicide, (C) 1 ppm fungicide, and (D) 10 ppm fungicide. Observation time is 96 hours. Survival, white blood cells, and red blood cells are analyzed using analysis of variance, while the feed response, shock response, and water quality are analyzed descriptively. The results showed that 10 ppm fungicide was not lethal to common carp and tilapia with a survival rate of almost 100%. During 96 hours of fungicide exposure, the average white blood cell (WBC) of common carp increased from 8.84-10.46 x 104 cells/mm3 to 9.56-11.48 x 104 cells/mm3. Meanwhile, the mean WBC of tilapia increased from 11.36-19.44 x 104 cells/mm3 to 20.52-37.38 x 104 cells/mm3. The average red blood cell (RBC) of common carp decreased from 6.60-7.01 x 106 cells/mm3 to 6.06-6.76 x 106 cells/mm3. Meanwhile, the mean RBC of tilapia decreased from 5.26-7.55 x 106 cells/mm3 to 2.21-3.76 x 106 cells/mm3. The results showed that the feed response did not change during the study, but the shock response decreased at 96 hours. Water quality during the study was still in the optimal range for common carp and tilapia culture. Key words : Bacillus amyloliquefaciens, fungicide, sublethal effect, common carp, tilapia

Abstract

This research focused on determining the best survival performance of carp (C. carpio) fingerlings in circular containers combined with venturi aerators to generate water current, then challenged by A. hydrophila. The research used an experimental method of Completely Randomized Design (CRD) with four treatments and four replications. The treatment used was the use of venturi aerators on circular containers: without water current as a control (A), with a water current of 0.06 ms?¹ (B), 0.1 ms?¹ (C), and 0.14 ms?¹ (D). The study was initiated by rearing 5-7 cm fish fingerlings for 40 days and followed by a challenge test for 14 days. Carp fingerlings were challenged by A. hydrophila intraperitoneally at a density of 10? CFU ml?¹. Each tank consists of 15 fingerlings. Parameters observed included survival rate, the number of red blood cells and white blood cells, macroscopic symptoms, and water quality. The results showed survival rate in treatment (D) was the best (water current of 0.14 ms?¹), 98% before the challenge period and 95% after the challenge period. In addition, it can increase the hematological parameters as seen from the increase in the number of red and white blood cells after the challenge test, from 1.043 x 106 cells mm³?¹ to 2.36 x 106 cells mm³?¹ and 2.7 x 104 cells mm³?¹ to 9.3 x 104 cells mm³?¹ respectively. And it shows an increased immune response as seen from the recovery acceleration in macroscopic symptoms on the seventh day after A. hydrophila injection. While water quality did not differ between control and treatments.Keywords : current circular generating tank, carp fingerling, Aeromonas hydrophila, immune response

Abstract

Kondisi pandemi Covid-19 memberikan efek ekonomi yang cukup signifikan terhadap masyarakat Indonesia. Daya beli yang menurun, membuat masyarakat harus mencari solusi untuk memenuhi kebutuhan pangan yang bergizi dengan harga terjangkau. Sistem akuaponik merupakan salah satu jalan keluar untuk pemenuhan kebutuhan gizi tersebut. Dengan diadakannya pengabdian pada masyarakat ini, diharapkan dapat menjadi model untuk kegiatan urban farming dengan memanfaatkan lahan yang terbatas. Model yang digunakan dalam kegiatan ini adalah pendidikan masyarakat dan pelatihan. Sistem akuaponik yang memadukan budidaya ikan dengan tanaman sayur memberikan alternatif bagi masyarakat Desa Tanjungsari untuk mendapatkan sumber pangan berprotein tinggi yang organik serta dengan harga yang terjangkau.
