Seachem and tetra only market substrate additive in Indonesia and not the substrate itself.
Seachem with the flourish tabs/starter pack.
Tetra selling initial sticks.
You need to add gravel to both.
Another alternative is to use JBL aquabasis/florapol or sera base fertiliser.
Sometimes you can also find dennerle.
So far a complete enriched substrate existing in the market is only Azoo plant bed. Look for then at ACE or Malaliwe LFSs. It looks a bit like ADA soil.
