Penggunaan ekstrak Ciplukan (Physalis angulata) untuk memacu pertumbuhan ikan Nila (Oreochromis niloticus)

Abstract

This study aimed to examine the effect of adding ciplukan (Physalis angulata) to feed on the growth of tilapia and to find a dose of ciplukan that was able to increase the growth of tilapia (Oreochromis niloticus). The test fish used were tilapia with an average size of 5-8 cm as many as 300 fish from the Center for Freshwater Aquaculture (BPBAT), Talelu. This research was conducted at the Aquaculture Technology Laboratory, Faculty of Fisheries and Marine Sciences, Sam Ratulangi University. This study used a completely randomized design (CRD) with 4 treatments, where each treatment had 3 replications so there were 15 experimental units, the treatment used was ciplukan flour with different concentrations consisting of: A: 0 g flour/kg feed, B : 10 g flour/ kg feed, C : 15 g flour/ kg feed, D : 20 g flour/ kg feed. The data collected consisted of fish weight to measure the fish growth. The results showed that the addition of ciplukan leaf extract in feed with different concentrations gave significantly different effects on the growth of tilapia with treatment B (10 g) showing the highest fish growth reaching 5.24 g, followed by treatment C (15 g) with the highest growth. reached 4.35 g. While the fish treated with D (20 g) only reached 3.16 g in weight where this value was not much different from the growth of fish in control A. Duncan's further test results showed that treatments B, C, D were not significantly different from each other, but these three treatments were very significantly different compared to fish that were not given ciplukan leaf extract. The study showed that ciplukan leaf extract added to feed gave significantly different effects on fish growth, with the best dose of 10 g extract/kg feed. Thus it can be concluded that ciplukan leaf extract can increase growth of Nile tilapia.
