Effectiveness of Pepaya Leaf Extract (Carica Papaya L.) to Control Ectoparasite Argulus on Common Carp (Cyprinus Carpio)

Abstract

Argulus controls on common carp can be done by using natural ingredients. However, due to the lack of information and products of natural ingredients, consumers choose to use chemicals products. One of natural ingredients that can be used is papaya leaf extract. Papaya leaves contain active ingredient alkaloid carpain, which is a vegetable insecticide and a potential antiparasite especially against Argulus. The method used in this extraction was the maseration method, which is a soaking process that continues to the treatment stage. The research design used was Completely Randomized Design with P0 control (without papaya leaf extract), 2 ppt, 4 ppt, and 6 ppt, and it was repeated five times. The main parameter in this study was the number of Argulus detached from goldfish. The data were then analyzed using Variance Analysis (ANAVA), then continued with Duncan Multiple Range Test with the lapse of the significance at 0.05%. The results showed that papaya leaf extract can control Argulus infestation on common carp and detach it from common carp. Treatment P0 (control) with an average percentage of the amount of Argulus that had been isolated was 0%, treatment P1 (2 ppt) equals to 24%, treatment P3 (4 ppt) equals to 52%, treatment P3 (6 ppt) equals to 88%. Treatments P1, P2, and P3 were not significantly different (P> 0.05), whereas P1, P2, and P3 were significantly different from P0 (P> 0.05). The effective dose of papaya leaf extract to control the Argulus infestation common carp was 6 ppt, which can isolate Argulus from common carp as much as 88%.
