I don't think so.. Just google-image Aselsan SARP and then compare the sensor at the front with this one (around 3:56), seems that they are using different sensors and different positions. Also looks like Aselsan is using specially built / heavily modified guns, while these guys only put an "everyday MG" (Minimi ..?) with very little modification (well, they have to modified AT LEAST the trigger-ing process). At 4:21 we can still see the rear sight and carrying handle
I'm NOT saying that they're doing a bad job, the little kinks can be iron out as time goes by, especially if they receive buying commitments from TNI (read: funds). To be fair, with tech nowadays it is quite easy to built an RCWS. Even the components available in civilian market is already good enough for this purpose.. I mean, they don't have to detect an ant movement on 2 kilometers radius do they?
With micro computers like Raspberry Pi, various sensors and a little coding skill, an RCWS is very feasible. There are lots of tutorial in internet for a start, such as:

and I even found one paper from Indos uni student that is talking about this:

There is no shame even it is not 100% "karya anak bangsa" and there is
very little thing to worry about getting an embargo as these things are quite cheap and available everywhere.
