PEMANFAATAN TEPUNG PACI-PACI (Leucas lavandulaefolia) UNTUK MENGOBATI INFEKSI Aeromonas hydrophila PADA IKAN PATIN (Pangasius sp.)

Abstract

Motile Aeromonas Septicaemia (MAS) is one of bacterial A. hydrophila disease frequently infecting freshwater fish include catfish (Pangasius sp.). Controling the disease of bacterial use chemical antibiotic will cause environment pollution. The aim of this research was to determine utilization of natural material that contain antibacterial such Leucas lavandulaefolia powder as antibacterial to treat of A. hydrophila infection for catfish. The implementation of research was from September until October 2014 at the Laboratorium Budidaya Perairan, Faculty of Agriculture, Sriwijaya University and Laboratorium UPT Klinik Kesehatan Sriwijaya University. Research method was using Completely Randomized Design (CRD) with five treat and three replications. The catfish was infected by A. hydrophila with clinical feature were (inflamed and hemorrhage) that give addition Leucas lavandulaefolia powder on commercial feed as many as 4%, 6%, 8%, and 10%. The result showed that addition 10 % of Leucas lavandulaefolia powder on commercial feed was the best to treat of A. hydrophila infection for catfish were significant (P<0,05). In vitro test result showed that Leucas lavandulaefolia powder at a concentration 10% as an antibacterial potential of A.hydrophila with inhibitor zone diameter 0.5 cm, at in vivo test the catfish that gives addition Leucas lavandulaefolia powder on commercial pellet as many as 10% capable hematocrit increase, reducing leucocyte completely, produce recovery percentage 84.44%, the survival rate 76.67%, highest absolute growth of catfish 3.03 g and higest absolute length of catfish 0.89 cm. Keywords : A. hydrophila, catfish, Leucas lavandulaefolia powder

Effectiveness of Herbal Diet Nigella sativa and Gracilaria verrucosa Against Non-specific Immunity of Tilapia (Oreochromis niloticus)

“…The results of the study Abd El-Hack et al (2020) proved that the bioactive compounds contained in black cumin such as alkaloids, triterpenoids, steroids, saponins, phenolics and flavonoids function as immunostimulants which can increase the percentage of hematocrit. African catfish fed black cumin diet can increase hematocrite levels (Dontriska, 2014). The black cumin diet at a dose of 50 g kg -1 feed on tilapia effectively increased the non-specific immune response which was marked by an increase in the percentage of hematocrite up to 34% (Silviana et al, 2022).…”

Improved immune response of common carp (Cyprinus carpio) by administration of mahang sirap (Macaranga involucrate) Leaf Extract

“…Respon antibodi merupakan respon imun humoral ketika dipapar dengan antigen. Pada ikan, respon imunnya terjadi secara seluler, biasa terjadi pada hari ke 1-5 setelah pemaparan (Rejeki et al, 2018).…”

Analisis In Vitro : Efektivitas Daun dan Kulit Durian (Durio zibethinus Murr) Terhadap Bakteri Edwardsiella tarda

“…Alkaloid dapat mencegah terbentuknya sintesis protein sehingga proses metabolimse pada bakteri menjadi terganggu dan akan membuat terhambatnya pertumbuhan bakteri (Munfaati et al, 2015). Alkaloid merupakan salah satu senyawa aktif yang dapat meningkatkan nafsu makan dan sistem imum pada ikan (Muntari et al, 2015). Tanin mempunyai kemampuan sebagai antibakteri yang dapat merusakkan lapisan pada sel bakteri (Suhartati & Roziqin, 2017).…”
