    Abstract: The duration of immersion in water and the composition of the filler material affects the performance of silicon rubber insulation material. This has been proven in studies that have been conducted on high voltage engineering laboratory, University of Hasanuddin. The objective of this study was to determine the effect of immersion time in the silicon rubber filled with fly ash. Besides this, another goal is to get the effect of fly ash filler material composition of the value of the relative permittivity, hydrophobic contact angle value and the value of the percentage change in the mass of silicon rubber insulators. This study uses a filler of coal fly ash with a variation of the mass of the silicon rubber composition of 0, 10, 20 and 30% (with code FFA 0, 10, 20 and 30%). Materials testing and test developed and implemented with the ASTM standard. The test results showed that the soaking time and the variation of the mass of filler material composition will worsen silicon rubber insulator material is shown by the increase relative permittivity value, increasing the value of the percentage change in mass and decrease the value of the contact angle.
