PENGARUH EKSTRAK DAUN PLETEKAN (Ruellia tuberosa L.) TERHADAP KADAR SGPT DAN SGOT PADA AYAM PEDAGING BROILER (Gallus gallus domesticus L.) SEBAGAI SUMBER BELAJAR BIOLOGI

The use of synthetic antibiotics as Antibiotic Growth Promoters (AGP) in broiler chickens (Gallus gallus domesticus L.) can indeed improve reproduction, maintain the health of livestock, and increase the efficiency of feed use. If these synthetic antibiotics are used excessively and continuously, it will cause residues and increase resistance to bacteria both in Gallus gallus domesticus L. and those who consume it. Tetracycline antibiotics are antibiotics that are often found in poultry meat such as Gallus gallus domesticus L.
This study aims to utilize the existence of wild plants, namely pletekan leaves (Ruellia tuberosa L.) as an alternative to antibiotics by looking at their effect on SGPT and SGPT levels of broiler broilers (Gallus gallus domesticus L.) and can be utilized as a learning resource at SMK Agribusiness Poultry. This research uses a quantitative approach with the type of research true experiment research. In this study gave treatment to broiler broilers (Gallus gallus domesticus L.) using pletekan leaf extract (Ruellia tuberosa L.) with concentrations of 125 ppm, 250 ppm, 375 ppm, 500 ppm, 625 ppm, and 1000 ppm. Furthermore, on day 35, chicken blood was taken to test SGPT and SGOT levels with the IFCC Kinetic method. The sampling technique used was simple random sampling and data analysis using normality test, homogeneity test, non-parametric test and anova test.
The results obtained were at a concentration of 125 ppm pletekan leaf extract (Ruellia tuberosa L.) did not increase SGPT and SGOT levels in broiler chickens (Gallus gallus domesticus L.). The conclusion of this study is that from the results of phytochemical screening on pletekan leaf extract (Ruellia tuberosa L.) there are secondary metabolite compounds of alkaloids and tannins. The concentration of 125 ppm is the optimal concentration and the results of this study can be used as a biology learning resource at SMK Agribusiness Poultry Phase F with learning outcomes on feed management and animal health.
