Hello GrabID_Utami Gendis, 
I noticed a jersey barrier was added to a segment of the secondary roundabout (https://www.openstreetmap.org/way/675198862). Is this barrier feature in OSM intended to model a divide between two opposing oneway lanes as seen in Mapillary (https://www.mapillary.com/app/?lat=-6.109019999999987&lng=106.73932439999999&z=17&pKey=312146917822785&focus=photo)? If so, it may be better to model as a feature separated linear feature between the two highway features - (linear barrier features are acceptable via OSMWiki - https://wiki.openstreetmap.org/wiki/Tag:barrier%3Djersey_barrier). 

The current modeling as a node-based barrier member of that way will block routing clock-wise around this roundabout for many users of OSM. If the barrier is intended to block travel on this roundabout, do you have updated resources to share for this change? That would be very helpful. Thanks and I look forward to hearing from you.
