Abstract

This research was carried out for 14 days starting on December 21, 2021 - January 03, 2022 at the Fish Seed Center Laboratory (BBI) Faculty of Agriculture, Riau Islamic University, Pekanbaru. The aim of this study was to determine the duration of immersion of the ethanolic extract of the leaves of senduduk bulu (Clidemia hirta) for the treatment of fungal infections of Saprolegnia sp and survival of gourami (Osphronemus gouramy) fry. The materials used in this study were 150 gourami fish seeds (10 fish/container) with a size of 3-4 cm, 95% ethanol solvent, ethanol extract of the leaves of senduduk bulu, Saprolegnia sp fungus from unfertilized catfish eggs and PF 500 pellets. The method used is an experimental method using a completely randomized design (CRD) with 5 levels of treatment and 3 replications, namely P1 (2 hours), P2 (3 hours), P3 (4 hours), P4 (5 hours) and P5 (6 hours). ) with a dose of 100 ppm of ethanol extract of the leaves of senduduk bulu used. The results showed that the best healing time for P5 treatment was (6 hours) of immersion for 7 days. Furthermore, the highest survival rate was found in treatment P1 with a (2 hour) immersion time of 90%. The results of water quality measurements in this study ranged from 27-31°C, pH 6.5-7.6, DO 2.6-4.3 and NH3 0.08-0.14 mg/l.
