Dengue Hemorrhagic Fever (DHF) continues to be a health issue in the world due to the fact many cases are detected late. A diagnostic device with a more efficient method is needed. By using the Finite Element Method (FEM) primarily based on field vectors and Raman enhancement more optimal sensors can be made. The methodology used is a simulation simulation to model the nanorod of a material irradiated with an electromagnetic wave in the Localized Surface Plasmon Resonance (LSPR) phenomenon. From the results obtained, the sensor will be optimal if using a metal material from silver, using a large Raman wavelength, using a nanorod with a smaller radius and have a small gap between. This is evidenced by the presence of the highest intensity compared to other variations. The higher the intensity of the EM wave field, the more sensitive the sensor can be. By using silver material, wavelength 785 nm, radius 20 nm, distance between nanorods 25 nm, the sensitivity of nanorod is 1.497 V/m for every 1 RIU increase in refractive index.
