JAKARTA, Indonesia – Indonesian Mosque Council (DMI) chairman Jusuf Kalla announced Sunday (January 26th) the launch of a nationwide campaign to reduce noise from amplified sermons, and improve quality of mosques, local media reported.

Saying most mosques-- even in affluent areas-- had substandard sound systems, Jusuf sent out 50 cars with more than 150 technicians, according to The Jakarta Post.

He also pushed for an amplification ban, saying loudspeakers should only be used for the call to prayer.

Jusuf called on government to do more to care for the country's mosques, warning they could become radicalism breeding grounds if not looked after.

He estimated improvement costs over three years for about 100,000 mosques at Rp. 300 billion ($24.7m), Republika reported.
