EFEK TOKSIK INSEKTISIDA NABATI BERBAHAN AKTIF EUGENOL DAN AZADIRACHTIN PADA KELANGSUNGAN HIDUP DAN PERTUMBUHAN IKAN MAS (Cyprinus carpio)

Abstract

This research aims to examine the effect of exposure to plant-based insecticides containing
active ingredients eugenol and azadirachtin on the survival and growth of common carp
(Cyprinus carpio). The study was conducted from September to October 2022 at the
Ciparanje Inland Fisheries Hatchery, Faculty of Fisheries and Marine Sciences, Universitas
Padjadjaran. The research method used was an experimental method, and the experimental
design employed was a completely randomized design (CRD). The study included six
treatments with three replications. The test fish used were Majalaya strain common carp
fingerling, measuring 7-8 cm, obtained from the Cibiru Fish Seed Center in Bandung City.
The treatments examined in this study were Treatment A (0 ppm), B (12.8 ppm), C (25.6
ppm), D (38.4 ppm), E (51.2 ppm), and F (64 ppm). The insecticides were administered
once at the beginning of the research in the water, which served as the maintenance
medium, according to the treatment concentrations. The parameters observed were survival
rate, growth, and water quality. Observations were conducted for 28 days after the
application of the plant-based insecticides. The highest percentage of survival was found in
Treatment A (control) at 100%, while the lowest percentage of survival was observed in
Treatment F (64 ppm) at 81.7%. The highest absolute length growth was recorded in
Treatment A (control) at 2.73 cm, and the lowest absolute length growth was observed in
Treatment F (64 ppm) at 1.97 cm. The highest weight growth was observed in Treatment A
(control) at 4.2 g, and the lowest absolute weight growth was found in Treatment F (64
ppm) at 2.6 g. The research indicates that the growth and survival of common carp
fingerling (Cyprinus carpio) decrease due to the influence of exposure to plant-based
insecticides containing active ingredients eugenol and azadirachtin.
