I think people get confused,
Langkah (with H) Baru is a silat school based in Gladstone, in central-nothern part Queensland- Australia.
It is definitely of Indonesian root. As far as I heard, the seniors (or the founder?) used to train Perisai Diri in Brisbane.
I agree with with kang Eric , the Indonesian should not adopt a holier-than-thou attitude toward Malaysia (or any other) with regard to Silat. All puak Melayu (and now everybody) have exactly the same right to claim as the inheritor of Silat.
Cheers
