Abstract
Specific Absorption Rate (SAR) is used to evaluate the safety of human exposure to Electromagnetic Fields, particularly from mobile devices. In Indonesia, based on the Decree of the Minister of Communication and Information No. 177 of 2024, all phones and tablets sold must undergo SAR testing in domestic laboratories. However, 5G device SAR testing is time consuming due to the large number of configurations required, delaying product launches and new technology adoption. This study conducted measurement trials using a Base Station Simulator (BSS), dipole antenna, and SAR Test System to propose a more efficient SAR testing method for 5G. The configuration involved fixed parameters (transmit power and resource block) and varied parameters (frequency, bandwidth, and modulation) to examine their effect on SAR values. The proposed configuration are high frequency, QPSK modulation, and the largest bandwidth proved optimal. By implementing this configuration, SAR testing time was reduced by 98.74%, and the testing process became 69.33 times more efficient.
