Jakarta. Dozens of mosques belonging to state-owned enterprises, ministries and government institutions have strong radical inclinations, a study has shown, revealing a new urgency for the government to step up preventive efforts on its own turf.

The study by the Association of Islamic Boarding Schools and Society Development (P3M) and social organization Rumah Kebangsaan in 2017 listed 41 out of 100 mosques surveyed in Jakarta as radical.

P3M and Rumah Kebangsaan conducted the survey between Sept. 29 and Oct. 21 by analyzing hundreds of video and audio recordings taken by volunteers at 35 mosques in ministries, 28 in government institutions and 37 in state-owned enterprises.

Released on Sunday (08/07), the study found that radical narratives were spread especially during Friday sermons, and included hate speech, calls for the establishment of a caliphate, and a negative portrayal of other faiths.

Mosques at state-owned enterprises are especially vulnerable. According to the study, 21 of them have been infiltrated by radical groups.

"The high indication of radicalism at these mosques shows a lack of attention from the government, as they are structurally under its management," it said and advised that the Indonesian Mosques Council (DMI) should look into the findings to take appropriate measures.

P3M chairman Agus Muhammad said moderate Islamic preachers should deliver sermons at government mosques.

"If moderate Islamic preachers are not active, these mosques will be overwhelmed by hardliners," Agus said, as quoted by NU Online.

He added that preventive measures can also be undertaken by ordinary citizens, who should report indications of radicalism to relevant authorities.
