Abstract

This research aims to identify the types of bioactive compounds in the methanol extract of betel leaves (Piper betle L) observing the Clear Zone. And knowing the inhibitory ability of methanol extract of betel leaves (Piper betle L). through determining the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against V. parahaemolyticus. This research used experimental methods and completely random sampling (RAL). By carrying out a GC-MS test to identify the bioactive compounds contained in betel leaves. Antibacterial activity test and minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) tests to determine the ability of betel leaf extract to inhibit Vibrio parahaemolyticus bacteria. And a challenge test to determine the survival rate. The results of descriptive analysis and Anova statistical tests show that betel leaf extract contains 5 secondary metabolic compounds. The use of betel leaf extract 10 mg/ml, 15 mg/ml, 20 mg/ml shows strong inhibitory power with a minimum concentration of 3.12 mg/ml and 6.25 mg/ml after the Survival Rate challenge test was carried out for vaname shrimp treated with 85% betel leaf extract, while the administration of betel leaves was also able to reduce the clinical symptoms experienced by vaname shrimp with a concentration of 50 mg/ml. Conclusion: These results identify that betel leaf extract has secondary metabolic compounds that can be used as antibacterials in white shrimp cultivation activities.

Abstract

Tilapia (Oreochromis niloticus, Linnaeus, 1758) is a dominant commodity in the Indonesian freshwater fishery industry, and its growth relies on feed. Pellet are feed that is processed through a factory mechanism or human intervention, based on the cultivators needs. Therefore, the purpose of this study was to determine the effect of pelleted feed with varying protein content on growth and survival of tilapia (Oreochromis niloticus) fry. This was conducted from April 2022 to June 2022, in Tasiwalie Village, Suppa District, Pinrang Regency. The test animals used were tilapia aged 30 days, and feed include omega-3, Hi-Pro-vite 781, and Prima feed 500 grams each. An experimental method was employed using a Completely Randomized Design (CRD) with three treatment and replications, where treatment A, B, and C were Prima Feed (39 41%), Hi-Pro Vite (protein 31 33%), and Omega feed (protein 13 16%), respectively. Artificial feed was given at a dose of 5%/body weight 3 times a day. Also, water quality management was carried out by measuring temperature, dissolved oxygen, pH, and ammonia. The results showed that different feed affected protein retention with the highest average value of 43.23%, the highest average fat retention of 48.56%, absolute weight growth of 1.58 g, absolute length growth of 2.33 cm, daily specific weight growth rate of 3.75%, daily specific length growth rate of 5.56%, and feed utilization efficiency 70.60%. Furthermore, the best growth was obtained in treatment A, involving Prime Feed from 39 41%. This study showed that the percentage of protein had a significant effect on growth and survival of tilapia. Therefore, the feed industry is needed to formulate requirements based on tilapia fish, to increase production.Keywords:TilapiaFeedGrowthSurvival
