PERFORMA PERTUMBUHAN DAN KELANGSUNGAN HIDUP IKAN NILA (Oreochromis niloticus) PASCA PAPARAN INSEKTISIDA NABATI BERBAHAN AKTIF AZADIRACHTIN

Abstract

Insecticides can be used to overcome pest attacks in agricultural and plantation sectors. The
botanical insecticide is more widely used because more friendly to the environment than
chemical insecticides. Neem is one of the plants that can be used as basic ingredient for
botanical insecticides because it contains the compound azadirachtin. Insecticide enter the
cultivation area because carried by flowing water. Tilapia is a fish that can be used as a
bioindicator of pollution levels, water quality, and changes in the aquatic environment. This
study aims to determine the effect of exposure insecticide with azadirachtin active ingredient
on growth and survival rate of tilapia. This research was conducted in March and August for
the preliminary test and September-October 2022 for the main test at Ciparanje Inland
Aquaculture Hatchery, Padjadjaran University. The fish used in this study averaged 6,70 ±
0,014 cm. This study used experimental method, Completely Randomized Design with five
treatments and three replications. The treatments used were exposure to insecticides with
different doses, namely A(0 ppm), B(26.25 ppm), C(52.5 ppm), D(78.75 ppm), E(105 ppm).
Parameters observed included absolute length growth and weight growth, survival rate, and
water quality until 28th day. Growth and survival data analyzed using the F test and
continued with Duncan's test at the 95% level of confidence. The results showed that
exposure insecticide can inhibited growth and affected the survival of tilapia. Treatment
C(52.5 ppm) is a safe concentration for the survival of tilapia and the highest growth is the
treatment without addition of insecticide.
