<![CDATA[This research was conducted at the Biology Laboratory, Faculty of Agriculture, Universitas Katolik Santo Thomas, Medan. This study aims to determine the potential of fragrant pandan leaf extract as a vegetable pesticide in controlling armyworm pests. This study used a non-factorial completely randomized design (CRD). The treatment factor was fragrant pandan leaf extract (Pw) which consisted of 5 treatments and 4 replications, namely: Pw0 = (control/without giving fragrant pandan leaf extract), Pw1 = 20 ml of fragrant pandan leaf extract, Pw2 = 40 ml of pandan leaf extract fragrant, Pw3 = 60 ml of fragrant pandan leaf extract and Pw4 = 80 ml of fragrant pandan leaf extract, each treatment added with 100 ml of distilled water. The results showed that the highest percentage of mortality (100%) at 108 hours after application (JSA) was found in the treatment of 80 ml of fragrant pandan leaf extract + 100 ml of aquadest. The fastest death time of 50% of armyworms was found in the treatment of 80 ml of fragrant pandan leaf extract + 100 ml of aquadest, which was 30 JSA.]]>
