Abstract
The use of mobile devices has become a primary necessity for the Indonesian society. The benefits of mobile devices are increasingly abundant. However, it is essential to consider the impact of electromagnetic exposure on health. Recently, government regulate Specific Absorption Rate (SAR) limits for mobile phones and computer tablets. The government strives to ensure that devices circulating in Indonesia comply with these SAR limits. Unfortunately, the number of laboratories in Indonesia capable of testing SAR is quite limited. This situation presents a business opportunity for telecommunications testing laboratories to invest in SAR testing systems. The author analyzes the techno-economic aspects of investing in SAR system tests using parameters such as Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PP). Two options are compared: the first involves investing in two complete SAR measurement systems, while the second entails investing in one measurement system with a backup probe. Both options allow for full operation of the SAR testing system, enabling consumers to request testing whenever needed. The calculations reveal that both options yield an NPV greater than zero, an IRR exceeding the specified interest rate, and the ability to recoup the investment within a six-year payback period. Consequently, this investment is deemed viable for implementation at present with current condition.
