This flag is modification of this
flag. Yellow color is from star in emblem of Indonesia
. Pentagon is roundel of Indonesia
and symbolizes Pancasila. In SVG file there are two pentagons, one yellow in red stripe and one red in white stripe. Please comment what is better and I will delete the other.
Reasons for upper position: similarity with flag for Malaysian language and typical "canton" position
Reasons for lower position: Indonesia is south from Malaysia and roundel of Indonesia is red pentagon
