Monday, July 28, 2025, the Ministry of Digital Communications (KOMDIGI) and the Directorate General of Digital Infrastructure (DJID) presented a Draft Ministerial Decree (RKM) on new standards for Technical Requirements for Broadcast Radio Receivers.
To ensure that broadcast radio receivers circulating in Indonesia are safe, compatible, ready to support digital broadcasting, and have disaster features as referenced in the new draft standard for Technical Requirements for Broadcast Radio Receivers, DJID invited stakeholders to present the DKM.
The new standard for Technical Requirements for Broadcast Radio Receivers focuses on the technical aspects that must be met by two categories of devices, namely passenger vehicle head units and portable receivers for households.

New Standard for Technical Requirements for Broadcast Radio Receivers
The draft Ministerial Decree (RKM) on the new standard for Technical Requirements for Broadcast Radio Receivers covers all aspects, such as power supply, electrical safety requirements, electromagnetic compatibility (EMC) requirements, radio frequency requirements, disaster early warning feature (EWF or EWS) requirements, and functionality requirements. The following are the details:
Power supply
The device shall support an AC or DC power source, according to the type of use. The working voltage must be within the SELV (Safety Extra Low Voltage) limit, maximum 42.4 V peak or 60 V DC.
Electrical safety
Electrical safety assessment parameters Broadcast Radio Receiver:
- Overvoltage or electrical strength or dielectric strength; and
- Leakage current or touch current
Technical reference standard test method:
- SNI IEC 60950-1
- SNI IEC 62368-1
- SNI 04-6253
- IEC 60065
Electromagnetic compatibility (EMC) requirements
Electromagnetic compatibility (EMC) requirements must meet three aspects: classification, immunity, and emission requirements. Here are the details:
- Classification requirements: Vehicular, fixed, or portable equipment.
- Immunity requirements: Following the provisions in the Sixth Dictum of the Ministerial Decree
- Emission requirements: SNI CISPR 32:2015 or IEC CISPR 32
Radio frequency requirements
Radio frequency requirements must fulfill three aspects, namely receiver working frequency, sensitivity, and Adjacent Channel Selectivity (ACS). Details of each requirement follow:

Through this Draft Ministerial Decree on Technical Requirements for Broadcast Radio Receivers, the Indonesian government hopes that the industry can be better prepared to provide devices that are reliable, safe, and in accordance with the development of global digital broadcast technology.
This new standard will serve as a reference for DJID certification in the future. Therefore, knowing the updates of this draft decision is necessary so that when it is enacted, broadcast radio receiver devices circulating in Indonesia are following the latest regulations.
