Abstrak (Berisi Bastraknya saja, Judul dan Nama Tidak Boleh di Masukan)
Radio Detection and Ranging (RADAR) is an electromagnetic wave technology used to detect objects at great distances. RADAR emits radio waves and if there are objects within the range of these waves, the radio waves will be reflected back towards the RADAR, so that the object will be detected by the RADAR. RADAR absorbing material (RAM) is a material that serves to absorb radio waves so that no reflected waves return to the RADAR. RAM is generally made of a carbon element core, and is in the form of paint that coats RADAR detection objects. In this study, a trial was conducted on the use of coconut shell charcoal as a carbon substitute. Coconut charcoal RAM was tested using VNA and proved to be successful as RAM in general with the smallest reflection-loss value obtained at -21.89 dB at a working frequency of 4-8 GHz. The researcher then ran a simulation using the CST studio suite 2019 to vary the thickness of the RAM, aiming to test the performance of the RAM. Based on previous research and simulations conducted by the author, it can be concluded that the thicker the RAM, the smaller the reflection-loss value obtained, which means the greater the absorption of RAM against electromagnetic waves. Key Words: Electromagnetic Waves, RADAR, RAM (RADAR Absorbing Material), Reflection-loss.
