ABSTRACT Putri, Ni Luh Putu Dian Utami. 2018. Effectiveness Test of Soursop Leaf Extract (Annona muricata L) as Antibacterial to Escherichia Coli Bacterial Growth. Final Project, Doctor Education Study Program, Faculty of Medicine, Wijaya University Kusuma Surabaya. Advisor: dr.Sianny Suryawati, Sp.Rad. Escherichia coli is an opportunistic bacteria that can spread easily from hands touching contaminated food or water and causing horizontal gene transfer. Some studies say, ethanol extract of soursop leaf contains flavonoid compound, which can serve as an antiseptic disinfectant. This study aims to determine the effect of ethanol extract of soursop leaf (Annona muricata L.) on the growth of Escherichia coli bacteria. With the population of bacteria used in this study is the bacteria Escherichia coli obtained from the Laboratory of Microbiology Faculty of Medicine, University of Wijaya Kusuma Surabaya and a large sample of research taken as many as 28 samples. For independent variable (independent) this research is ethanol extract of soursop leaf (Annona muricata L.) and dependent variable of this research is growth of Escherichia coli bacteria and its controlled variables are soursop leaf (dry or wet), incubation temperature, and provision of test materials. While the data analysis research using One Way ANOVA statistical test. The results showed that there was significant difference between control group and treatment group so that it showed that MBC activity of Escherichia coli bacteria was formed by soursop leaf extract (Annona muricata L) as an antibacterial agent in vitro.
